+
+       Ivan's description of the patch follows. Note that a few pieces like
+       the GC_malloc(0) patch, were not applied since an alternate had been
+       previously applied.  A few differed stylistically from the rest of
+       the code (mostly casts to void * instead of target type),
+       or were classified as too minor to bother.  Note that
+       all of Ivan's static declarations which did not correct outright
+       naming bugs (as a few did), where replaced by STATIC, which is
+       ignored by default.
+
+       - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
+       GC_malloc(0));
+       - addition of missing getter/setter functions for public variables
+       (may be useful if compiled as Win32 DLL);
+       - addition of missing GC_API for some exported functions;
+       - addition of missing "static" declarator for internal functions
+       and variables (where possible);
+       - replacement of all remaining K&R-style definitions with ANSI
+       C ones (__STDC__ macro is not used anymore);
+       - addition of some Win32 macro definitions (that may be missing in
+       the standard headers supplied with a compiler) for GWW_VDB mode;
+       - elimination of most compiler warnings (except for
+       "uninitialized data" warning);
+       - several typos correction;
+       - missing parenthesis addition in macros in some header files of
+       "libatomic_ops" module.
+
+       My highlights based on reading the patch:
+
+       * allchblk.c: Remove GC_freehblk_ptr decl.

+#
+#  Rename this file "Makefile".
+#
+
+# Primary targets:
+# gc.a - builds basic library
+# c++ - adds C++ interface to library and include directory
+# cords - adds cords (heavyweight strings) to library and include directory
+# test - prints porting information, then builds basic version of gc.a, and runs
+#        some tests of collector and cords.  Does not add cords or c++ interface to gc.a
+# cord/de.exe - builds dumb editor based on cords.

+# without optimization.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+# -DFIND_LEAK causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions
+# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
+#   (Clients should also define SOLARIS_THREADS and then include
+#   gc.h before performing thr_ or GC_ operations.)
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_private.h for consequences.)
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,

+# test - prints porting information, then builds basic version of gc.a,

+
+A few files have other copyright holders. A few of the files needed
+to use the GNU-style build procedure come with a modified GPL license
+that appears not to significantly restrict use of the collector, though
+use of those files for a purpose other than building the collector may
+require the resulting code to be covered by the GPL.
+
+For more details and the names of other contributors, see the
+doc/README* files and include/gc.h.  This file describes typical use of
+the collector on a machine that is already supported.
+
+For the version number, see doc/README or version.h.
+
+INSTALLATION:
+Under UN*X, Linux:
+Alternative 1 (the old way): type "make test" in this directory.
+        Link against gc.a.  With the most recent GC distributions
+        you may have to type "make -f Makefile.direct test" or
+        copy Makefile.direct to Makefile first.
+
+Alternative 2 (the new way): type
+        "./configure --prefix=<dir>; make; make check; make install".
+        Link against <dir>/lib/libgc.a or <dir>/lib/libgc.so.
+        See README.autoconf for details
+
+Under Windows 95, 98, Me, NT, or 2000:
+copy the appropriate makefile to MAKEFILE, read it, and type "nmake test".
+(Under Windows, this assumes you have Microsoft command-line tools
+installed, and suitably configured.)
+Read the machine specific README in the doc directory if one exists.
+
+If you need thread support, you will need to follow the special
+platform-dependent instructions (win32), or define GC_THREADS
+as described in doc/README.macros, or possibly use
+--enable-threads=posix when running the configure script.
+
+If you wish to use the cord (structured string) library with the stand-alone
+Makefile.direct, type "make cords", after copying to "Makefile".
+(This requires an ANSI C compiler.  You may
+need to redefine CC in the Makefile. The CORD_printf implementation in
+cordprnt.c is known to be less than perfectly portable.  The rest of the
+package should still work.)
+
+If you wish to use the collector from C++, type "make c++", or use
+--enable-cplusplus with the configure script.   With Makefile.direct,
+these ones add further files to gc.a and to the include subdirectory.
+With the alternate build process,this generates libgccpp.
+See cord/cord.h and include/gc_cpp.h.
+
+TYPICAL USE:
+Include "gc.h" from the include subdirectory.  Link against the
+appropriate library ("gc.a" under UN*X).  Replace calls to malloc
+by calls to GC_MALLOC, and calls to realloc by calls to GC_REALLOC.
+If the object is known to never contain pointers, use GC_MALLOC_ATOMIC
+instead of GC_MALLOC.
+
+Define GC_DEBUG before including gc.h for additional checking.
+
+More documentation on the collector interface can be found at
+http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcinterface.html,
+in doc/README and other files in the doc directory, and in include/gc.h .
+
+WARNINGS:
+
+Do not store the only pointer to an object in memory allocated
+with system malloc, since the collector usually does not scan
+memory allocated in this way.
+
+Use with threads may be supported on your system, but requires the
+collector to be built with thread support.  See Makefile.  The collector
+does not guarantee to scan thread-local storage (e.g. of the kind
+accessed with pthread_getspecific()).  The collector does scan
+thread stacks though, so generally the best solution is to ensure that
+any pointers stored in thread-local storage are also stored on the
+thread's stack for the duration of their lifetime.

+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+OVERVIEW

+    This is intended to be a general purpose, garbage collecting storage
+allocator.  The algorithms used are described in:

+
+  Possible interactions between the collector and optimizing compilers are
+discussed in
+
+Boehm, H., and D. Chase, "A Proposal for GC-safe C Compilation",
+The Journal of C Language Translation 4, 2 (December 1992).
+
+and
+
+Boehm H., "Simple GC-safe Compilation", Proceedings
+of the ACM SIGPLAN '96 Conference on Programming Language Design and
+Implementation.
+
+(Some of these are also available from
+http://www.hpl.hp.com/personal/Hans_Boehm/papers/, among other places.)
+
+  Unlike the collector described in the second reference, this collector
+operates either with the mutator stopped during the entire collection
+(default) or incrementally during allocations.  (The latter is supported
+on fewer machines.)  On the most common platforms, it can be built
+with or without thread support.  On a few platforms, it can take advantage
+of a multiprocessor to speed up garbage collection.
+
+  Many of the ideas underlying the collector have previously been explored
+by others.  Notably, some of the run-time systems developed at Xerox PARC
+in the early 1980s conservatively scanned thread stacks to locate possible
+pointers (cf. Paul Rovner, "On Adding Garbage Collection and Runtime Types
+to a Strongly-Typed Statically Checked, Concurrent Language"  Xerox PARC
+CSL 84-7).  Doug McIlroy wrote a simpler fully conservative collector that
+was part of version 8 UNIX (tm), but appears to not have received
+widespread use.
+
+  Rudimentary tools for use of the collector as a leak detector are included
+(see http://www.hpl.hp.com/personal/Hans_Boehm/gc/leak.html),
+as is a fairly sophisticated string package "cord" that makes use of the
+collector.  (See doc/README.cords and H.-J. Boehm, R. Atkinson, and M. Plass,
+"Ropes: An Alternative to Strings", Software Practice and Experience 25, 12
+(December 1995), pp. 1315-1330.  This is very similar to the "rope" package
+in Xerox Cedar, or the "rope" package in the SGI STL or the g++ distribution.)

+
+
+GENERAL DESCRIPTION
+
+  This is a garbage collecting storage allocator that is intended to be
+used as a plug-in replacement for C's malloc.
+
+  Since the collector does not require pointers to be tagged, it does not
+attempt to ensure that all inaccessible storage is reclaimed.  However,
+in our experience, it is typically more successful at reclaiming unused
+memory than most C programs using explicit deallocation.  Unlike manually
+introduced leaks, the amount of unreclaimed memory typically stays
+bounded.
+
+  In the following, an "object" is defined to be a region of memory allocated
+by the routines described below.
+
+  Any objects not intended to be collected must be pointed to either
+from other such accessible objects, or from the registers,
+stack, data, or statically allocated bss segments.  Pointers from
+the stack or registers may point to anywhere inside an object.
+The same is true for heap pointers if the collector is compiled with
+ALL_INTERIOR_POINTERS defined, or GC_all_interior_pointers is otherwise
+set, as is now the default.
+
+Compiling without ALL_INTERIOR_POINTERS may reduce accidental retention
+of garbage objects, by requiring pointers from the heap to the beginning
+of an object.  But this no longer appears to be a significant
+issue for most programs occupying a small fraction of the possible
+address space.
+
+There are a number of routines which modify the pointer recognition
+algorithm.  GC_register_displacement allows certain interior pointers
+to be recognized even if ALL_INTERIOR_POINTERS is nor defined.
+GC_malloc_ignore_off_page allows some pointers into the middle of large objects
+to be disregarded, greatly reducing the probability of accidental
+retention of large objects.  For most purposes it seems best to compile
+with ALL_INTERIOR_POINTERS and to use GC_malloc_ignore_off_page if
+you get collector warnings from allocations of very large objects.
+See README.debugging for details.
+
+  WARNING: pointers inside memory allocated by the standard "malloc" are not
+seen by the garbage collector.  Thus objects pointed to only from such a
+region may be prematurely deallocated.  It is thus suggested that the
+standard "malloc" be used only for memory regions, such as I/O buffers, that
+are guaranteed not to contain pointers to garbage collectable memory.
+Pointers in C language automatic, static, or register variables,
+are correctly recognized.  (Note that GC_malloc_uncollectable has semantics
+similar to standard malloc, but allocates objects that are traced by the
+collector.)
+
+  WARNING: the collector does not always know how to find pointers in data
+areas that are associated with dynamic libraries.  This is easy to
+remedy IF you know how to find those data areas on your operating
+system (see GC_add_roots).  Code for doing this under SunOS, IRIX 5.X and 6.X,
+HP/UX, Alpha OSF/1, Linux, and win32 is included and used by default.  (See
+README.win32 for win32 details.)  On other systems pointers from dynamic
+library data areas may not be considered by the collector.
+If you're writing a program that depends on the collector scanning
+dynamic library data areas, it may be a good idea to include at least
+one call to GC_is_visible() to ensure that those areas are visible
+to the collector.
+
+  Note that the garbage collector does not need to be informed of shared
+read-only data.  However if the shared library mechanism can introduce
+discontiguous data areas that may contain pointers, then the collector does
+need to be informed.
+
+  Signal processing for most signals may be deferred during collection,
+and during uninterruptible parts of the allocation process.
+Like standard ANSI C mallocs, by default it is unsafe to invoke
+malloc (and other GC routines) from a signal handler while another
+malloc call may be in progress. Removing -DNO_SIGNALS from Makefile
+attempts to remedy that.  But that may not be reliable with a compiler that
+substantially reorders memory operations inside GC_malloc.
+
+  The allocator/collector can also be configured for thread-safe operation.
+(Full signal safety can also be achieved, but only at the cost of two system
+calls per malloc, which is usually unacceptable.)
+WARNING: the collector does not guarantee to scan thread-local storage
+(e.g. of the kind accessed with pthread_getspecific()).  The collector
+does scan thread stacks, though, so generally the best solution is to
+ensure that any pointers stored in thread-local storage are also
+stored on the thread's stack for the duration of their lifetime.
+(This is arguably a longstanding bug, but it hasn't been fixed yet.)
+
+INSTALLATION AND PORTABILITY
+
+  As distributed, the collector operates silently
+In the event of problems, this can usually be changed by defining the
+GC_PRINT_STATS or GC_PRINT_VERBOSE_STATS environment variables.  This
+will result in a few lines of descriptive output for each collection.
+(The given statistics exhibit a few peculiarities.
+Things don't appear to add up for a variety of reasons, most notably
+fragmentation losses.  These are probably much more significant for the
+contrived program "test.c" than for your application.)
+
+  On most Un*x-like platforms, the collector can be built either using a
+GNU autoconf-based build infrastructure (type "configure; make" in the
+simplest case), or with a classic makefile by itself (type
+"cp Makefile.direct Makefile; make").  Here we focus on the latter option.
+On other platforms, typically only the latter option is available, though
+with a different supplied Makefile.)
+
+  For the Makefile.direct-based process, typing "make test" instead of "make"
+will automatically build the collector and then run setjmp_test and gctest.
+Setjmp_test will give you information about configuring the collector, which is
+useful primarily if you have a machine that's not already supported.  Gctest is
+a somewhat superficial test of collector functionality.  Failure is indicated
+by a core dump or a message to the effect that the collector is broken.  Gctest
+takes about a second to two to run on reasonable 2007 vintage desktops.  It may
+use up to about 30MB of memory.  (The multi-threaded version will use more.
+64-bit versions may use more.) "Make test" will also, as its last step, attempt
+to build and test the "cord" string library.)
+
+  Makefile.direct will generate a library gc.a which you should link against.
+Typing "make cords" will add the cord library to gc.a.
+
+  The GNU style build process understands the usual targets.  "Make check"
+runs a number of tests.  "Make install" installs at least libgc, and libcord.
+Try "./configure --help" to see the configuration options.  It is currently
+not possible to exercise all combinations of build options this way.
+
+  It is suggested that if you need to replace a piece of the collector
+(e.g. GC_mark_rts.c) you simply list your version ahead of gc.a on the
+ld command line, rather than replacing the one in gc.a.  (This will
+generate numerous warnings under some versions of AIX, but it still
+works.)
+
+  All include files that need to be used by clients will be put in the
+include subdirectory.  (Normally this is just gc.h.  "Make cords" adds
+"cord.h" and "ec.h".)
+
+  The collector currently is designed to run essentially unmodified on
+machines that use a flat 32-bit or 64-bit address space.
+That includes the vast majority of Workstations and X86 (X >= 3) PCs.
+(The list here was deleted because it was getting too long and constantly
+out of date.)
+
+  In a few cases (Amiga, OS/2, Win32, MacOS) a separate makefile
+or equivalent is supplied.  Many of these have separate README.system
+files.
+
+  Dynamic libraries are completely supported only under SunOS/Solaris,
+(and even that support is not functional on the last Sun 3 release),
+Linux, FreeBSD, NetBSD, IRIX 5&6, HP/UX, Win32 (not Win32S) and OSF/1
+on DEC AXP machines plus perhaps a few others listed near the top
+of dyn_load.c.  On other machines we recommend that you do one of
+the following:
+
+  1) Add dynamic library support (and send us the code).
+  2) Use static versions of the libraries.
+  3) Arrange for dynamic libraries to use the standard malloc.
+     This is still dangerous if the library stores a pointer to a
+     garbage collected object.  But nearly all standard interfaces
+     prohibit this, because they deal correctly with pointers
+     to stack allocated objects.  (Strtok is an exception.  Don't
+     use it.)
+
+  In all cases we assume that pointer alignment is consistent with that
+enforced by the standard C compilers.  If you use a nonstandard compiler
+you may have to adjust the alignment parameters defined in gc_priv.h.
+Note that this may also be an issue with packed records/structs, if those
+enforce less alignment for pointers.
+
+  A port to a machine that is not byte addressed, or does not use 32 bit
+or 64 bit addresses will require a major effort.  A port to plain MSDOS
+or win16 is hard.
+
+  For machines not already mentioned, or for nonstandard compilers,
+some porting suggestions are provided in the "porting.html" file.
+
+THE C INTERFACE TO THE ALLOCATOR
+
+  The following routines are intended to be directly called by the user.
+Note that usually only GC_malloc is necessary.  GC_clear_roots and GC_add_roots
+calls may be required if the collector has to trace from nonstandard places
+(e.g. from dynamic library data areas on a machine on which the
+collector doesn't already understand them.)  On some machines, it may
+be desirable to set GC_stacktop to a good approximation of the stack base.
+(This enhances code portability on HP PA machines, since there is no
+good way for the collector to compute this value.)  Client code may include
+"gc.h", which defines all of the following, plus many others.
+
+1)  GC_malloc(nbytes)
+    - allocate an object of size nbytes.  Unlike malloc, the object is
+      cleared before being returned to the user.  Gc_malloc will
+      invoke the garbage collector when it determines this to be appropriate.
+      GC_malloc may return 0 if it is unable to acquire sufficient
+      space from the operating system.  This is the most probable
+      consequence of running out of space.  Other possible consequences
+      are that a function call will fail due to lack of stack space,
+      or that the collector will fail in other ways because it cannot
+      maintain its internal data structures, or that a crucial system
+      process will fail and take down the machine.  Most of these
+      possibilities are independent of the malloc implementation.
+
+2)  GC_malloc_atomic(nbytes)
+    - allocate an object of size nbytes that is guaranteed not to contain any
+      pointers.  The returned object is not guaranteed to be cleared.
+      (Can always be replaced by GC_malloc, but results in faster collection
+      times.  The collector will probably run faster if large character
+      arrays, etc. are allocated with GC_malloc_atomic than if they are
+      statically allocated.)
+
+3)  GC_realloc(object, new_size)
+    - change the size of object to be new_size.  Returns a pointer to the
+      new object, which may, or may not, be the same as the pointer to
+      the old object.  The new object is taken to be atomic iff the old one
+      was.  If the new object is composite and larger than the original object,
+      then the newly added bytes are cleared (we hope).  This is very likely
+      to allocate a new object, unless MERGE_SIZES is defined in gc_priv.h.
+      Even then, it is likely to recycle the old object only if the object
+      is grown in small additive increments (which, we claim, is generally bad
+      coding practice.)
+
+4)  GC_free(object)
+    - explicitly deallocate an object returned by GC_malloc or
+      GC_malloc_atomic.  Not necessary, but can be used to minimize
+      collections if performance is critical.  Probably a performance
+      loss for very small objects (<= 8 bytes).
+
+5)  GC_expand_hp(bytes)
+    - Explicitly increase the heap size.  (This is normally done automatically
+      if a garbage collection failed to GC_reclaim enough memory.  Explicit
+      calls to GC_expand_hp may prevent unnecessarily frequent collections at
+      program startup.)
+
+6)  GC_malloc_ignore_off_page(bytes)
+        - identical to GC_malloc, but the client promises to keep a pointer to
+          the somewhere within the first 256 bytes of the object while it is
+          live.  (This pointer should normally be declared volatile to prevent
+          interference from compiler optimizations.)  This is the recommended
+          way to allocate anything that is likely to be larger than 100Kbytes
+          or so.  (GC_malloc may result in failure to reclaim such objects.)
+
+7)  GC_set_warn_proc(proc)
+        - Can be used to redirect warnings from the collector.  Such warnings
+          should be rare, and should not be ignored during code development.
+
+8) GC_enable_incremental()
+    - Enables generational and incremental collection.  Useful for large
+      heaps on machines that provide access to page dirty information.
+      Some dirty bit implementations may interfere with debugging
+      (by catching address faults) and place restrictions on heap arguments
+      to system calls (since write faults inside a system call may not be
+      handled well).
+
+9) Several routines to allow for registration of finalization code.
+   User supplied finalization code may be invoked when an object becomes
+   unreachable.  To call (*f)(obj, x) when obj becomes inaccessible, use
+        GC_register_finalizer(obj, f, x, 0, 0);
+   For more sophisticated uses, and for finalization ordering issues,
+   see gc.h.
+
+  The global variable GC_free_space_divisor may be adjusted up from its
+default value of 4 to use less space and more collection time, or down for
+the opposite effect.  Setting it to 1 or 0 will effectively disable collections
+and cause all allocations to simply grow the heap.
+
+  The variable GC_non_gc_bytes, which is normally 0, may be changed to reflect
+the amount of memory allocated by the above routines that should not be
+considered as a candidate for collection.  Careless use may, of course, result
+in excessive memory consumption.
+
+  Some additional tuning is possible through the parameters defined
+near the top of gc_priv.h.
+
+  If only GC_malloc is intended to be used, it might be appropriate to define:
+
+#define malloc(n) GC_malloc(n)
+#define calloc(m,n) GC_malloc((m)*(n))
+
+  For small pieces of VERY allocation intensive code, gc_inl.h
+includes some allocation macros that may be used in place of GC_malloc
+and friends.
+
+  All externally visible names in the garbage collector start with "GC_".
+To avoid name conflicts, client code should avoid this prefix, except when
+accessing garbage collector routines or variables.
+
+  There are provisions for allocation with explicit type information.
+This is rarely necessary.  Details can be found in gc_typed.h.
+
+THE C++ INTERFACE TO THE ALLOCATOR:
+
+  The Ellis-Hull C++ interface to the collector is included in
+the collector distribution.  If you intend to use this, type
+"make c++" after the initial build of the collector is complete.
+See gc_cpp.h for the definition of the interface.  This interface
+tries to approximate the Ellis-Detlefs C++ garbage collection
+proposal without compiler changes.
+
+  Very often it will also be necessary to use gc_allocator.h and the
+allocator declared there to construct STL data structures.  Otherwise
+subobjects of STL data structures will be allocated using a system
+allocator, and objects they refer to may be prematurely collected.
+
+USE AS LEAK DETECTOR:
+
+  The collector may be used to track down leaks in C programs that are
+intended to run with malloc/free (e.g. code with extreme real-time or
+portability constraints).  To do so define FIND_LEAK in Makefile
+This will cause the collector to invoke the report_leak
+routine defined near the top of reclaim.c whenever an inaccessible
+object is found that has not been explicitly freed.  Such objects will
+also be automatically reclaimed.
+  If all objects are allocated with GC_DEBUG_MALLOC (see next section), then
+the default version of report_leak will report at least the source file and
+line number at which the leaked object was allocated.  This may sometimes be
+sufficient.  (On a few machines, it will also report a cryptic stack trace.
+If this is not symbolic, it can sometimes be called into a sympolic stack
+trace by invoking program "foo" with "callprocs foo".  Callprocs is a short
+shell script that invokes adb to expand program counter values to symbolic
+addresses.  It was largely supplied by Scott Schwartz.)
+  Note that the debugging facilities described in the next section can
+sometimes be slightly LESS effective in leak finding mode, since in
+leak finding mode, GC_debug_free actually results in reuse of the object.
+(Otherwise the object is simply marked invalid.)  Also note that the test
+program is not designed to run meaningfully in FIND_LEAK mode.
+Use "make gc.a" to build the collector.
+
+DEBUGGING FACILITIES:
+
+  The routines GC_debug_malloc, GC_debug_malloc_atomic, GC_debug_realloc,
+and GC_debug_free provide an alternate interface to the collector, which
+provides some help with memory overwrite errors, and the like.
+Objects allocated in this way are annotated with additional
+information.  Some of this information is checked during garbage
+collections, and detected inconsistencies are reported to stderr.
+
+  Simple cases of writing past the end of an allocated object should
+be caught if the object is explicitly deallocated, or if the
+collector is invoked while the object is live.  The first deallocation
+of an object will clear the debugging info associated with an
+object, so accidentally repeated calls to GC_debug_free will report the
+deallocation of an object without debugging information.  Out of
+memory errors will be reported to stderr, in addition to returning NULL.
+
+  GC_debug_malloc checking  during garbage collection is enabled
+with the first call to GC_debug_malloc.  This will result in some
+slowdown during collections.  If frequent heap checks are desired,
+this can be achieved by explicitly invoking GC_gcollect, e.g. from
+the debugger.
+
+  GC_debug_malloc allocated objects should not be passed to GC_realloc
+or GC_free, and conversely.  It is however acceptable to allocate only
+some objects with GC_debug_malloc, and to use GC_malloc for other objects,
+provided the two pools are kept distinct.  In this case, there is a very
+low probability that GC_malloc allocated objects may be misidentified as
+having been overwritten.  This should happen with probability at most
+one in 2**32.  This probability is zero if GC_debug_malloc is never called.
+
+  GC_debug_malloc, GC_malloc_atomic, and GC_debug_realloc take two
+additional trailing arguments, a string and an integer.  These are not
+interpreted by the allocator.  They are stored in the object (the string is
+not copied).  If an error involving the object is detected, they are printed.
+
+  The macros GC_MALLOC, GC_MALLOC_ATOMIC, GC_REALLOC, GC_FREE, and
+GC_REGISTER_FINALIZER are also provided.  These require the same arguments
+as the corresponding (nondebugging) routines.  If gc.h is included
+with GC_DEBUG defined, they call the debugging versions of these
+functions, passing the current file name and line number as the two
+extra arguments, where appropriate.  If gc.h is included without GC_DEBUG
+defined, then all these macros will instead be defined to their nondebugging
+equivalents.  (GC_REGISTER_FINALIZER is necessary, since pointers to
+objects with debugging information are really pointers to a displacement
+of 16 bytes form the object beginning, and some translation is necessary
+when finalization routines are invoked.  For details, about what's stored
+in the header, see the definition of the type oh in debug_malloc.c)
+
+INCREMENTAL/GENERATIONAL COLLECTION:
+
+The collector normally interrupts client code for the duration of
+a garbage collection mark phase.  This may be unacceptable if interactive
+response is needed for programs with large heaps.  The collector
+can also run in a "generational" mode, in which it usually attempts to
+collect only objects allocated since the last garbage collection.
+Furthermore, in this mode, garbage collections run mostly incrementally,
+with a small amount of work performed in response to each of a large number of
+GC_malloc requests.
+
+This mode is enabled by a call to GC_enable_incremental().
+
+Incremental and generational collection is effective in reducing
+pause times only if the collector has some way to tell which objects
+or pages have been recently modified.  The collector uses two sources
+of information:
+
+1. Information provided by the VM system.  This may be provided in
+one of several forms.  Under Solaris 2.X (and potentially under other
+similar systems) information on dirty pages can be read from the
+/proc file system.  Under other systems (currently SunOS4.X) it is
+possible to write-protect the heap, and catch the resulting faults.
+On these systems we require that system calls writing to the heap
+(other than read) be handled specially by client code.
+See os_dep.c for details.
+
+2. Information supplied by the programmer.  We define "stubborn"
+objects to be objects that are rarely changed.  Such an object
+can be allocated (and enabled for writing) with GC_malloc_stubborn.
+Once it has been initialized, the collector should be informed with
+a call to GC_end_stubborn_change.  Subsequent writes that store
+pointers into the object must be preceded by a call to
+GC_change_stubborn.
+
+This mechanism performs best for objects that are written only for
+initialization, and such that only one stubborn object is writable
+at once.  It is typically not worth using for short-lived
+objects.  Stubborn objects are treated less efficiently than pointerfree
+(atomic) objects.
+
+A rough rule of thumb is that, in the absence of VM information, garbage
+collection pauses are proportional to the amount of pointerful storage
+plus the amount of modified "stubborn" storage that is reachable during
+the collection.
+
+Initial allocation of stubborn objects takes longer than allocation
+of other objects, since other data structures need to be maintained.
+
+We recommend against random use of stubborn objects in client
+code, since bugs caused by inappropriate writes to stubborn objects
+are likely to be very infrequently observed and hard to trace.
+However, their use may be appropriate in a few carefully written
+library routines that do not make the objects themselves available
+for writing by client code.
+
+
+BUGS:
+
+  Any memory that does not have a recognizable pointer to it will be
+reclaimed.  Exclusive-or'ing forward and backward links in a list
+doesn't cut it.
+  Some C optimizers may lose the last undisguised pointer to a memory
+object as a consequence of clever optimizations.  This has almost
+never been observed in practice.  Send mail to gc@linux.hpl.hp.com
+for suggestions on how to fix your compiler.
+  This is not a real-time collector.  In the standard configuration,
+percentage of time required for collection should be constant across
+heap sizes.  But collection pauses will increase for larger heaps.
+They will decrease with the number of processors if parallel marking
+is enabled.
+(On 2007 vintage machines, GC times may be on the order of 5 msecs
+per MB of accessible memory that needs to be scanned and processor.
+Your mileage may vary.)  The incremental/generational collection facility
+may help in some cases.
+  Please address bug reports to gc@linux.hpl.hp.com.  If you are
+contemplating a major addition, you might also send mail to ask whether
+it's already been done (or whether we tried and discarded it).

+    Garbage Collector (parallel iversion) for ix86 DG/UX Release R4.20MU07
+
+
+     *READ* the file README.QUICK.
+
+     You need the GCC-3.0.3 rev (DG/UX) compiler to build this tree.
+     This compiler has the new "dgux386" threads package implemented.
+     It also supports the switch "-pthread" needed to link correctly
+     the DG/UX's -lrte -lthread with -lgcc and the system's -lc.
+     Finally we support parralleli-mark for the SMP DG/UX machines.
+     To build the garbage collector do:
+
+      ./configure --enable-parallel-mark
+      make
+      make gctest
+
+     Before you run "gctest" you need to set your LD_LIBRARY_PATH
+     correctly so that "gctest" can find the shared library libgc.
+     Alternatively you can do a configuration
+
+      ./configure --enable-parallel-mark --disable-shared
+
+     to build only the static version of libgc.
+
+     To enable debugging messages please do:
+     1) Add the "--enable-gc-debug" flag during configuration.
+     2) Edit the file linux-threads.c and uncommnect the line:
+
+     /* #define DEBUG_THREADS 1 */ to --->
+
+     #define DEBUG_THREADS 1
+
+     Then give "make" as usual.
+
+     In a machine with 4 CPUs (my own machine) the option parallel
+     mark (aka --enable-parallel-mark) makes a BIG difference.

+
+Patrick Beard's Notes for building GC v4.12 with CodeWarrior Pro 2:
+----------------------------------------------------------------------------
+The current build environment for the collector is CodeWarrior Pro 2.
+Projects for CodeWarrior Pro 2 (and for quite a few older versions)
+are distributed in the file Mac_projects.sit.hqx. The project file
+:Mac_projects:gc.prj builds static library versions of the collector.
+:Mac_projects:gctest.prj builds the GC test suite.
+
+Configuring the collector is still done by editing the files
+:Mac_files:MacOS_config.h and :Mac_files:MacOS_Test_config.h.
+
+Lars Farm's suggestions on building the collector:
+----------------------------------------------------------------------------
+Garbage Collection on MacOS - a manual 'MakeFile'
+-------------------------------------------------
+
+Project files and IDE's are great on the Macintosh, but they do have
+problems when used as distribution media. This note tries to provide
+porting instructions in pure TEXT form to avoid those problems. A manual
+'makefile' if you like.
+
+    GC version:     4.12a2
+    Codewarrior:    CWPro1
+    date:           18 July 1997
+
+The notes may or may not apply to earlier or later versions of the
+GC/CWPro. Actually, they do apply to earlier versions of both except that
+until recently a project could only build one target so each target was a
+separate project. The notes will most likely apply to future versions too.
+Possibly with minor tweaks.
+
+This is just to record my experiences. These notes do not mean I now
+provide a supported port of the GC to MacOS. It works for me. If it works
+for you, great. If it doesn't, sorry, try again...;-) Still, if you find
+errors, please let me know.

+
+Porting to MacOS is a bit more complex than it first seems. Which MacOS?
+68K/PowerPC? Which compiler? Each supports both 68K and PowerPC and offer a
+large number of (unique to each environment) compiler settings. Each
+combination of compiler/68K/PPC/settings require a unique combination of
+standard libraries. And the IDE's does not select them for you. They don't
+even check that the library is built with compatible setting and this is
+the major source of problems when porting the GC (and otherwise too).
+
+You will have to make choices when you configure the GC. I've made some
+choices here, but there are other combinations of settings and #defines
+that work too.
+
+As for target settings the major obstacles may be:
+- 68K Processor: check "4-byte Ints".
+- PPC Processor: uncheck "Store Static Data in TOC".
+
+What you need to do:
+===================
+
+1) Build the GC as a library
+2) Test that the library works with 'test.c'.
+3) Test that the C++ interface 'gc_cpp.cc/h' works with 'test_cpp.cc'.
+
+1) The Libraries:
+=================
+I made one project with four targets (68K/PPC tempmem or appheap). One target
+will suffice if you're able to decide which one you want. I wasn't...
+
+Codewarrior allows a large number of compiler/linker settings. I used these:
+
+Settings shared by all targets:
+------------------------------
+o Access Paths:
+  - User Paths:   the GC folder
+  - System Paths: {Compiler}:Metrowerks Standard Library:
+                  {Compiler}:MacOS Support:Headers:
+                  {Compiler}:MacOS Support:MacHeaders:
+o C/C++ language:
+  - inlining: normal
+  - direct to SOM: off
+  - enable/check: exceptions, RTTI, bool (and if you like pool strings)
+
+PowerPC target settings
+-----------------------
+o Target Settings:
+  - name of target
+  - MacOS PPC Linker
+o PPC Target
+  - name of library
+o C/C++ language
+  - prefix file as described below
+o PPC Processor
+  - Struct Alignment: PowerPC
+  - uncheck "Store Static Data in TOC" -- important!
+    I don't think the others matter, I use full optimization and its ok
+o PPC Linker
+  - Factory Settings (SYM file with full paths, faster linking, dead-strip
+    static init, Main: __start)
+
+
+68K target settings
+-------------------
+o Target Settings:
+  - name of target
+  - MacOS 68K Linker
+o 68K Target
+  - name of library
+  - A5 relative data
+o C/C++ language
+  - prefix file as described below
+o 68K Processor
+  - Code model: smart
+  - Struct alignment: 68K
+  - FP: SANE
+  - enable 4-Byte Ints -- important!
+    I don't think the others matter. I selected...
+  - enable: 68020
+  - enable: global register allocation
+o IR Optimizer
+  - enable: Optimize Space, Optimize Speed
+    I suppose the others would work too, but haven't tried...
+o 68K Linker
+  - Factory Settings (New Style MacsBug,SYM file with full paths,
+    A6 Frames, fast link, Merge compiler glue into segment 1,
+    dead-strip static init)
+
+Prefix Files to configure the GC sources
+----------------------------------------
+The Codewarrior equivalent of commandline compilers -DNAME=X is to use
+prefix-files. A TEXT file that is automatically #included before the first byte
+of every source file. I used these:
+
+---- ( cut here ) ----  gc_prefix_tempmem.h     -- 68K and PPC -----

+same as for test.c
+
+For convenience I used one test-project with several targets so that all
+test apps are build at once. Two for each library to test: test.c and
+gc_app.cc. When I was satisfied that the libraries were ok. I put the
+libraries + gc.h + the c++ interface-file in a folder that I then put into
+the MSL hierarchy so that I don't have to alter access-paths in projects
+that use the GC.
+
+After that, just add the proper GC library to your project and the GC is in
+action! malloc will call GC_malloc and free GC_free, new/delete too. You
+don't have to call free or delete. You may have to be a bit cautious about
+delete if you're freeing other resources than RAM. See gc_cpp.h. You can
+also keep coding as always with delete/free. That works too. If you want,
+"include <gc.h> and tweak it's use a bit.
+
+Symantec SPM
+============
+It has been a while since I tried the GC in SPM, but I think that the above
+instructions should be sufficient to guide you through in SPM too. SPM
+needs to know where the global data is. Use the files 'datastart.c' and
+'dataend.c'. Put 'datastart.c' at the top of your project and 'dataend.c'
+at the bottom  of your project so that all data is surrounded. This is not
+needed in Codewarrior because it provides intrinsic variables
+__datastart__, __data_end__ that wraps all globals.
+
+Source Changes (GC 4.12a2)
+==========================
+Very few. Just one tiny in the GC, not strictly needed.
+- MacOS.c line 131 in routine GC_MacFreeTemporaryMemory()
+  change #       if !defined(SHARED_LIBRARY_BUILD)
+  to     #       if !defined(SILENT) && !defined(SHARED_LIBRARY_BUILD)
+  To turn off a message when the application quits (actually, I faked
+  this change by #defining SHARED_LIBRARY_BUILD in a statically linked
+  library for more than a year without ill effects but perhaps this is
+  better).
+
+- test_cpp.cc
+  made the first lines of main() look like this:
+  ------------
+  int main( int argc, char* argv[] ) {
+  #endif
+  #if macintosh                             // MacOS
+    char* argv_[] = {"test_cpp","10"};      //   doesn't
+    argv=argv_;                             //     have a
+    argc = sizeof(argv_)/sizeof(argv_[0]);  //       commandline
+  #endif                                    //
+
+  int i, iters, n;
+  # ifndef __GNUC__
+   alloc dummy_to_fool_the_compiler_into_doing_things_it_currently_cant_handle;
+  ------------
+
+- config.h [now gcconfig.h]
+  __MWERKS__ does not have to mean MACOS. You can use Codewarrior to
+  build a Win32 or BeOS library and soon a Rhapsody library. You may
+  have to change that #if...
+
+
+
+   It worked for me, hope it works for you.

+
+
+Patrick Beard's instructions (may be dated):
+
+v4.3 of the collector now runs under Symantec C++/THINK C v7.0.4, and
+Metrowerks C/C++ v4.5 both 68K and PowerPC. Project files are provided
+to build and test the collector under both development systems.
+
+Configuration
+-------------
+
+To configure the collector, under both development systems, a prefix file
+is used to set preprocessor directives. This file is called "MacOS_config.h".
+Also to test the collector, "MacOS_Test_config.h" is provided.
+
+Testing
+-------
+
+To test the collector (always a good idea), build one of the gctest projects,
+gctest.¹ (Symantec C++/THINK C), mw/gctest.68K.¹, or mw/gctest.PPC.¹. The
+test will ask you how many times to run; 1 should be sufficient.
+
+Building 
+--------
+
+For your convenience project files for the major Macintosh development
+systems are provided.
+
+For Symantec C++/THINK C, you must build the two projects gclib-1.¹ and
+gclib-2.¹. It has to be split up because the collector has more than 32k
+of static data and no library can have more than this in the Symantec
+environment. (Future versions will probably fix this.)
+
+For Metrowerks C/C++ 4.5 you build gc.68K.¹/gc.PPC.¹ and the result will
+be a library called gc.68K.lib/gc.PPC.lib.
+
+Using
+-----
+
+Under Symantec C++/THINK C, you can just add the gclib-1.¹ and gclib-2.¹
+projects to your own project. Under Metrowerks, you add gc.68K.lib or
+gc.PPC.lib and two additional files. You add the files called datastart.c
+and dataend.c to your project, bracketing all files that use the collector.
+See mw/gctest.¹ for an example.
+
+Include the projects/libraries you built above into your own project,
+#include "gc.h", and call GC_malloc. You don't have to call GC_free.

+            Kjetil S. Matheussen's notes (28-11-2000)
+===========================================================================
+Compiles under SAS/C again. Should allso still compile under other
+amiga compilers without big changes. I haven't checked if it still
+works under gcc, because I don't have gcc for amiga. But I have
+updated 'Makefile', and hope it compiles fine.
+
+
+WHATS NEW:
+
+1.
+   Made a pretty big effort in preventing GCs allocating-functions from returning
+   chip-mem.
+
+   The lower part of the new file AmigaOS.c does this in various ways, mainly by
+   wrapping GC_malloc, GC_malloc_atomic, GC_malloc_uncollectable,
+   GC_malloc_atomic_uncollectable, GC_malloc_stubborn, GC_malloc_ignore_off_page
+   and GC_malloc_atomic_ignore_off_page. GC_realloc is allso wrapped, but
+   doesn't do the same effort in preventing to return chip-mem.
+   Other allocating-functions (f.ex. GC_*_typed_) can probably be
+   used without any problems, but beware that the warn hook will not be called.
+   In case of problems, don't define GC_AMIGA_FASTALLOC.
+
+   Programs using more time actually using the memory allocated
+   (instead of just allocate and free rapidly) have
+   the most to earn on this, but even gctest now normally runs twice
+   as fast and uses less memory, on my poor 8MB machine.
+
+   The changes have only effect when there is no more
+   fast-mem left. But with the way GC works, it
+   could happen quite often. Beware that an atexit handler had to be added,
+   so using the abort() function will make a big memory-loss.
+   If you absolutely must call abort() instead of exit(), try calling
+   the GC_amiga_free_all_mem function before abort().
+
+   New amiga-spesific compilation flags:
+
+   GC_AMIGA_FASTALLOC - By NOT defining this option, GC will work like before,
+                        it will not try to force fast-mem out of the OS, and
+                        it will use normal calloc for allocation, and the rest
+                        of the following flags will have no effect.
+
+   GC_AMIGA_ONLYFAST - Makes GC never to return chip-mem. GC_AMIGA_RETRY have
+                       no effect if this flag is set.
+
+   GC_AMIGA_GC - If gc returns NULL, do a GC_gcollect, and try again. This
+                 usually is a success with the standard GC configuration. 
+                 It is allso the most important flag to set to prevent
+                 GC from returning chip-mem. Beware that it slows down a lot
+                 when a program is rapidly allocating/deallocating when
+                 theres either very little fast-memory left or verly little
+                 chip-memory left. Its not a very common situation, but gctest
+                 sometimes (very rare) use many minutes because of this.
+
+   GC_AMIGA_RETRY - If gc succeed allocating memory, but it is chip-mem,
+                    try again and see if it is fast-mem. Most of the time,
+                    it will actually return fast-mem for the second try.
+                    I have set max number of retries to 9 or size/5000. You
+                    can change this if you like. (see GC_amiga_rec_alloc())
+
+   GC_AMIGA_PRINTSTATS - Gather some statistics during the execution of a
+                         program, and prints out the info when the atexit-handler
+                         is called.
+
+   My reccomendation is to set all this flags, except GC_AMIGA_PRINTSTATS and
+   GC_AMIGA_ONLYFAST.
+
+   If your program demands high response-time, you should
+   not define GC_AMIGA_GC, and possible allso define GC_AMIGA_ONLYFAST.
+   GC_AMIGA_RETRY does not seem to slow down much.
+
+   Allso, when compiling up programs, and GC_AMIGA_FASTALLOC was not defined when
+   compilling gc, you can define GC_AMIGA_MAKINGLIB to avoid having these allocation-
+   functions wrapped. (see gc.h)
+
+   Note that GC_realloc must not be called before any of
+   the other above mentioned allocating-functions have been called. (shouldn't be
+   any programs doing so either, I hope).
+
+   Another note. The allocation-function is wrapped when defining
+   GC_AMIGA_FASTALLOC by letting the function go thru the new
+   GC_amiga_allocwrapper_do function-pointer (see gc.h). Means that
+   sending function-pointers, such as GC_malloc, GC_malloc_atomic, etc.,
+   for later to be called like f.ex this, (*GC_malloc_functionpointer)(size),
+   will not wrap the function. This is normally not a big problem, unless
+   all allocation function is called like this, which will cause the
+   atexit un-allocating function never to be called. Then you either
+   have to manually add the atexit handler, or call the allocation-
+   functions function-pointer functions like this;
+   (*GC_amiga_allocwrapper_do)(size,GC_malloc_functionpointer).
+   There are probably better ways this problem could be handled, unfortunately,
+   I didn't find any without rewriting or replacing a lot of the GC-code, which
+   I really didn't want to. (Making new GC_malloc_* functions, and just
+   define f.ex GC_malloc as GC_amiga_malloc should allso work).
+
+
+   New amiga-spesific function:
+
+     void GC_amiga_set_toany(void (*func)(void));
+
+   'func' is a function that will be called right before gc has to change
+   allocation-method from MEMF_FAST to MEMF_ANY. Ie. when it is likely
+   it will return chip-mem.
+
+
+2. A few small compiler-spesific additions to make it compile with SAS/C again.
+
+3. Updated and rewritten the smakefile, so that it works again and that
+   the "unnecesarry" 'SCOPTIONS' files could be removed. Allso included
+   the cord-smakefile stuff in the main smakefile, so that the cord smakefile
+   could be removed too. By writing smake -f Smakefile.smk, both gc.lib and
+   cord.lib will be made.
+
+
+
+STILL MISSING:
+
+Programs can not be started from workbench, at least not for SAS/C. (Martin
+Tauchmanns note about that it now works with workbench is definitely wrong
+when concerning SAS/C). I guess it works if you use the old "#if 0'ed"-code,
+but I haven't tested it. I think the reason for MT to replace the
+"#if 0'ed"-code was only because it was a bit to SAS/C-spesific. But I
+don't know. An iconx-script solves this problem anyway.
+
+
+BEWARE!
+
+-To run gctest, set the stack to around 200000 bytes first.
+-SAS/C-spesific: cord will crash if you compile gc.lib with
+ either parm=reg or parm=both. (missing legal prototypes for
+ function-pointers someplace is the reason I guess.).

+===========================================================================
+WHO DID WHAT
+
+The original Amiga port was made by Jesper Peterson. I (Michel Schinz)
+modified it slightly to reflect the changes made in the new official
+distributions, and to take advantage of the new SAS/C 6.x features. I also
+created a makefile to compile the "cord" package (see the cord
+subdirectory).
+
+TECHNICAL NOTES
+
+In addition to Jesper's notes, I have the following to say:
+
+- Starting with version 4.3, gctest checks to see if the code segment is
+  added to the root set or not, and complains if it is. Previous versions
+  of this Amiga port added the code segment to the root set, so I tried to
+  fix that. The only problem is that, as far as I know, it is impossible to
+  know which segments are code segments and which are data segments (there
+  are indeed solutions to this problem, like scanning the program on disk
+  or patch the LoadSeg functions, but they are rather complicated). The
+  solution I have chosen (see os_dep.c) is to test whether the program
+  counter is in the segment we are about to add to the root set, and if it
+  is, to skip the segment. The problems are that this solution is rather
+  awkward and that it works only for one code segment. This means that if
+  your program has more than one code segment, all of them but one will be
+  added to the root set. This isn't a big problem in fact, since the
+  collector will continue to work correctly, but it may be slower.
+
+  Anyway, the code which decides whether to skip a segment or not can be
+  removed simply by not defining AMIGA_SKIP_SEG. But notice that if you do
+  so, gctest will complain (it will say that "GC_is_visible produced wrong
+  failure indication"). However, it may be useful if you happen to have
+  pointers stored in a code segment (you really shouldn't).
+
+  If anyone has a good solution to the problem of finding, when a program
+  is loaded in memory, whether a segment is a code or a data segment,
+  please let me know.
+
+PROBLEMS
+
+If you have any problem with this version, please contact me at
+schinz@alphanet.ch (but do *not* send long files, since we pay for
+every mail!).

+
+WHY I PORTED TO THE AMIGA
+
+The sole reason why I made this port was as a first step in getting
+the Sather(*) language on the Amiga. A port of this language will
+be done as soon as the Sather 1.0 sources are made available to me.
+Given this motivation, the garbage collection (GC) port is rather
+minimal.

+This port assumes that the startup code linked with target programs
+is that supplied with SAS/C versions 6.0 or later. This allows
+assumptions to be made about where to find the stack base pointer
+and data segments when programs are run from WorkBench, as opposed
+to running from the CLI. The compiler dependent code is all in the
+GC_get_stack_base() and GC_register_data_segments() functions, but
+may spread as I add Amiga specific features.
+
+Given that SAS/C was assumed, the port is set up to be built with
+"smake" using the "SMakefile". Compiler options in "SCoptions" can
+be set with "scopts" program. Both "smake" and "scopts" are part of
+the SAS/C commercial development system.
+
+In keeping with the porting philosophy outlined above, this port
+will not behave well with Amiga specific code. Especially not inter-
+process comms via messages, and setting up public structures like
+Intuition objects or anything else in the system lists. For the
+time being the use of this library is limited to single threaded
+ANSI/POSIX  compliant or near-complient code. (ie. Stick to stdio
+for now). Given this limitation there is currently no mechanism for
+allocating "CHIP" or "PUBLIC" memory under the garbage collector.
+I'll add this after giving it considerable thought. The major
+problem is the entire physical address space may have to me scanned,
+since there is no telling who we may have passed memory to.
+
+If you allocate your own stack in client code, you will have to
+assign the pointer plus stack size to GC_stackbottom.
+
+The initial stack size of the target program can be compiled in by
+setting the __stack symbol (see SAS documentaion). It can be over-
+ridden from the CLI by running the AmigaDOS "stack" program, or from
+the WorkBench by setting the stack size in the tool types window.
+
+SAS/C COMPILER OPTIONS (SCoptions)
+
+You may wish to check the "CPU" code option is appropriate for your
+intended target system.
+
+Under no circumstances set the "StackExtend" code option in either
+compiling the library or *ANY* client code.
+
+All benign compiler warnings have been suppressed. These mainly
+involve lack of prototypes in the code, and dead assignments
+detected by the optimizer.
+
+THE GOOD NEWS
+
+The library as it stands is compatible with the GigaMem commercial
+virtual memory software, and probably similar PD software.
+
+The performance of "gctest" on an Amiga 2630 (68030 @ 25Mhz)
+compares favourably with an HP9000 with similar architecture (a 325
+with a 68030 I think).
+
+-----------------------------------------------------------------------
+
+The Amiga port has been brought to you by:
+
+Jesper Peterson.
+
+jep@mtiame.mtia.oz.au          (preferred, but 1 week turnaround)
+jep@orca1.vic.design.telecom.au (that's orca<one>, 1 day turnaround)
+
+At least one of these addresses should be around for a while, even
+though I don't work for either of the companies involved.

+From: Margaret Fleck
+
+Here's the key details of what worked for me, in case anyone else needs them.
+There may well be better ways to do some of this, but ....
+   -- Margaret
+
+
+The badge4 has a StrongArm-1110 processor and a StrongArm-1111 coprocessor.  
+
+Assume that the garbage collector distribution is unpacked into /home/arm/gc6.0,
+which is visible to both the ARM machine and a linux desktop (e.g. via NFS mounting).
+
+Assume that you have a file /home/arm/config.site with contents something like the
+example attached below.  Notice that our local ARM toolchain lives in
+/skiff/local.
+
+Go to /home/arm/gc6.0 directory.  Do
+  CONFIG_SITE=/home/arm/config.site ./configure --target=arm-linux
+--prefix=/home/arm/gc6.0
+
+On your desktop, do:
+   make
+   make install
+The main garbage collector library should now be in ../gc6.0/lib/libgc.so.  
+
+To test the garbage collector, first do the following on your desktop
+   make gctest
+   ./gctest
+Then do the following on the ARM machine
+   cd .libs
+   ./lt-gctest
+
+Do not try to do "make test" (the usual way of running the test
+program).  This does not work and seems to erase some of the important
+files.
+
+The gctest program claims to have succeeded.  Haven't run any further tests
+with it, though I'll be doing so in the near future.

+Starting from GC v6.0, we support GNU-style builds based on automake,
+autoconf and libtool.  This is based almost entirely on Tom Tromey's work
+with gcj.
+
+To build and install libraries use
+
+configure; make; make install
+
+The advantages of this process are:
+
+1) It should eventually do a better job of automatically determining the
+right compiler to use, etc.  It probably already does in some cases.
+
+2) It tries to automatically set a good set of default GC parameters for
+the platform (e.g. thread support).  It provides an easier way to configure
+some of the others.
+
+3) It integrates better with other projects using a GNU-style build process.
+
+4) It builds both dynamic and static libraries.
+
+The known disadvantages are:
+
+1) The build scripts are much more complex and harder to debug (though largely
+standard).  I don't understand them all, and there's probably lots of redundant
+stuff.
+
+2) It probably doesn't work on all Un*x-like platforms yet.  It probably will
+never work on the rest.
+
+3) The scripts are not yet complete.  Some of the standard GNU targets don't
+yet work.  (Corrections/additions are very welcome.)
+
+The distribution should contain all files needed to run "configure" and "make",
+as well as the sources needed to regenerate the derived files.  (If I missed
+some, please let me know.)
+
+Note that the distribution comes with a "Makefile" which will be overwritten
+by "configure" with one that is not at all equivalent to the original.  The
+distribution contains a copy of the original "Makefile" in "Makefile.direct".
+
+Important options to configure:
+
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [/usr/local]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [same as prefix]
+  --enable-threads=TYPE   choose threading package
+  --enable-parallel-mark  parallelize marking and free list construction
+  --enable-gc-debug (--enable-full-debug before about 7.0)
+                          include full support for pointer back-tracing etc.
+
+
+Unless --prefix is set (or --exec-prefix or one of the more obscure options),
+make install will install libgc.a and libgc.so in /usr/local/bin, which
+would typically require the "make install" to be run as root.
+
+Most commonly --enable-threads=posix or will be needed.  --enable-parallel-mark
+is recommended for multiprocessors if it is supported on the platform.

+This is a rough history of garbage collector bugs and versions.
+
+This has been maintained with varying diligence over the years.
+
+I made an attempt to include recent contributors here.  I apologize for any
+omissions.
+
+RECENT UPDATES ARE RECORDED IN ../ChangeLog FILE INSTEAD TO CONFORM TO
+MORE COMMON CONVENTIONS.
+
+-------------------------
+
+  Version 1.3 and immediately preceding versions contained spurious
+assembly language assignments to TMP_SP.  Only the assignment in the PC/RT
+code is necessary.  On other machines, with certain compiler options,
+the assignments can lead to an unsaved register being overwritten.
+Known to cause problems under SunOS 3.5 WITHOUT the -O option.  (With
+-O the compiler recognizes it as dead code.  It probably shouldn't,
+but that's another story.)
+
+  Version 1.4 and earlier versions used compile time determined values
+for the stack base.  This no longer works on Sun 3s, since Sun 3/80s use
+a different stack base.  We now use a straightforward heuristic on all
+machines on which it is known to work (incl. Sun 3s) and compile-time
+determined values for the rest.  There should really be library calls
+to determine such values.
+
+  Version 1.5 and earlier did not ensure 8 byte alignment for objects
+allocated on a sparc based machine.
+
+  Version 1.8 added ULTRIX support in gc_private.h.
+  
+  Version 1.9 fixed a major bug in gc_realloc.
+  
+  Version 2.0 introduced a consistent naming convention for collector
+routines and added support for registering dynamic library data segments
+in the standard mark_roots.c.  Most of the data structures were revamped.
+The treatment of interior pointers was completely changed.  Finalization
+was added.  Support for locking was added.  Object kinds were added.
+We added a black listing facility to avoid allocating at addresses known
+to occur as integers somewhere in the address space.  Much of this
+was accomplished by adapting ideas and code from the PCR collector.
+The test program was changed and expanded.
+
+  Version 2.1 was the first stable version since 1.9, and added support
+for PPCR.
+
+  Version 2.2 added debugging allocation, and fixed various bugs.  Among them:
+- GC_realloc could fail to extend the size of the object for certain large object sizes.
+- A blatant subscript range error in GC_printf, which unfortunately
+  wasn't exercised on machines with sufficient stack alignment constraints.
+- GC_register_displacement did the wrong thing if it was called after
+  any allocation had taken place.
+- The leak finding code would eventually break after 2048 byte
+  byte objects leaked.
+- interface.c didn't compile.
+- The heap size remained much too small for large stacks.
+- The stack clearing code behaved badly for large stacks, and perhaps
+  on HP/PA machines.
+
+  Version 2.3 added ALL_INTERIOR_POINTERS and fixed the following bugs:
+- Missing declaration of etext in the A/UX version.
+- Some PCR root-finding problems.
+- Blacklisting was not 100% effective, because the plausible future
+  heap bounds were being miscalculated.
+- GC_realloc didn't handle out-of-memory correctly.
+- GC_base could return a nonzero value for addresses inside free blocks.
+- test.c wasn't really thread safe, and could erroneously report failure
+  in a multithreaded environment.  (The locking primitives need to be
+  replaced for other threads packages.)
+- GC_CONS was thoroughly broken.
+- On a SPARC with dynamic linking, signals stayed diabled while the
+  client code was running.
+  (Thanks to Manuel Serrano at INRIA for reporting the last two.)
+  
+  Version 2.4 added GC_free_space_divisor as a tuning knob, added
+  support for OS/2 and linux, and fixed the following bugs:
+- On machines with unaligned pointers (e.g. Sun 3), every 128th word could
+  fail to be considered for marking.
+- Dynamic_load.c erroneously added 4 bytes to the length of the data and
+  bss sections of the dynamic library.  This could result in a bad memory
+  reference if the actual length was a multiple of a page.  (Observed on
+  Sun 3.  Can probably also happen on a Sun 4.)
+  (Thanks to Robert Brazile for pointing out that the Sun 3 version
+  was broken.  Dynamic library handling is still broken on Sun 3s
+  under 4.1.1U1, but apparently not 4.1.1.  If you have such a machine,
+  use -Bstatic.)
+  
+  Version 2.5 fixed the following bugs:
+- Removed an explicit call to exit(1)
+- Fixed calls to GC_printf and GC_err_printf, so the correct number of
+  arguments are always supplied.  The OS/2 C compiler gets confused if
+  the number of actuals and the number of formals differ.  (ANSI C
+  doesn't require this to work.  The ANSI sanctioned way of doing things
+  causes too many compatibility problems.)
+  
+  Version 3.0  added generational/incremental collection and stubborn
+  objects.
+
+  Version 3.1 added the following features:
+- A workaround for a SunOS 4.X SPARC C compiler
+  misfeature that caused problems when the collector was turned into
+  a dynamic library.  
+- A fix for a bug in GC_base that could result in a memory fault.
+- A fix for a performance bug (and several other misfeatures) pointed
+  out by Dave Detlefs and Al Dosser.
+- Use of dirty bit information for static data under Solaris 2.X.
+- DEC Alpha/OSF1 support (thanks to Al Dosser).
+- Incremental collection on more platforms.
+- A more refined heap expansion policy.  Less space usage by default.
+- Various minor enhancements to reduce space usage, and to reduce
+  the amount of memory scanned by the collector.
+- Uncollectable allocation without per object overhead.
+- More conscientious handling of out-of-memory conditions.
+- Fixed a bug in debugging stubborn allocation.
+- Fixed a bug that resulted in occasional erroneous reporting of smashed
+  objects with debugging allocation.
+- Fixed bogus leak reports of size 4096 blocks with FIND_LEAK.
+
+  Version 3.2 fixed a serious and not entirely repeatable bug in
+  the incremental collector.  It appeared only when dirty bit info
+  on the roots was available, which is normally only under Solaris.
+  It also added GC_general_register_disappearing_link, and some
+  testing code.  Interface.c disappeared.
+
+  Version 3.3 fixes several bugs and adds new ports:
+- PCR-specific bugs.
+- Missing locking in GC_free, redundant FASTUNLOCK
+  in GC_malloc_stubborn, and 2 bugs in
+  GC_unregister_disappearing_link.
+  All of the above were pointed out by Neil Sharman
+  (neil@cs.mu.oz.au).
+- Common symbols allocated by the SunOS4.X dynamic loader
+  were not included in the root set.
+- Bug in GC_finalize (reported by Brian Beuning and Al Dosser)
+- Merged Amiga port from Jesper Peterson (untested)
+- Merged NeXT port from Thomas Funke (significantly
+  modified and untested)
+
+  Version 3.4:
+- Fixed a performance bug in GC_realloc.
+- Updated the amiga port.
+- Added NetBSD and 386BSD ports.
+- Added cord library.
+- Added trivial performance enhancement for
+  ALL_INTERIOR_POINTERS.  (Don't scan last word.)
+  
+  Version 3.5
+- Minor collections now mark from roots only once, if that
+  doesn't cause an excessive pause.
+- The stack clearing heuristic was refined to prevent anomalies
+  with very heavily recursive programs and sparse stacks.
+- Fixed a bug that prevented mark stack growth in some cases.
+  GC_objects_are_marked should be set to TRUE after a call
+  to GC_push_roots and as part of GC_push_marked, since
+  both can now set mark bits.  I think this is only a performance
+  bug, but I wouldn't bet on it.  It's certainly very hard to argue
+  that the old version was correct.
+- Fixed an incremental collection bug that prevented it from
+  working at all when HBLKSIZE != getpagesize()
+- Changed dynamic_loading.c to include gc_priv.h before testing
+  DYNAMIC_LOADING.  SunOS dynamic library scanning
+  must have been broken in 3.4.
+- Object size rounding now adapts to program behavior.
+- Added a workaround (provided by Manuel Serrano and
+  colleagues) to a long-standing SunOS 4.X (and 3.X?) ld bug
+  that I had incorrectly assumed to have been squished.
+  The collector was broken if the text segment size was within
+  32 bytes of a multiple of 8K bytes, and if the beginning of
+  the data segment contained interesting roots.  The workaround
+  assumes a demand-loadable executable.  The original may have
+  have "worked" in some other cases.
+- Added dynamic library support under IRIX5.
+- Added support for EMX under OS/2 (thanks to Ari Huttunen).
+  
+Version 3.6:
+- fixed a bug in the mark stack growth code that was introduced
+  in 3.4.
+- fixed Makefile to work around DEC AXP compiler tail recursion
+  bug.
+
+Version 3.7:
+- Added a workaround for an HP/UX compiler bug.
+- Fixed another stack clearing performance bug.  Reworked
+  that code once more.
+  
+Version 4.0:
+- Added support for Solaris threads (which was possible
+  only by reimplementing some fraction of Solaris threads,
+  since Sun doesn't currently make the thread debugging
+  interface available).
+- Added non-threads win32 and win32S support.
+- (Grudgingly, with suitable muttering of obscenities) renamed
+  files so that the collector distribution could live on a FAT
+  file system.  Files that are guaranteed to be useless on
+  a PC still have long names.  Gc_inline.h and gc_private.h
+  still exist, but now just include  gc_inl.h and gc_priv.h.
+- Fixed a really obscure bug in finalization that could cause
+  undetected mark stack overflows.  (I would be surprised if
+  any real code ever tickled this one.)
+- Changed finalization code to dynamically resize the hash
+  tables it maintains.  (This probably does not matter for well-
+  -written code.  It no doubt does for C++ code that overuses
+  destructors.)
+- Added typed allocation primitives.  Rewrote the marker to
+  accommodate them with more reasonable efficiency.  This
+  change should also speed up marking for GC_malloc allocated
+  objects a little.  See gc_typed.h for new primitives.
+- Improved debugging facilities slightly.  Allocation time
+  stack traces are now kept by default on SPARC/SUNOS4.
+  (Thanks to Scott Schwartz.)
+- Added better support for small heap applications.
+- Significantly extended cord package.  Fixed a bug in the
+  implementation of lazily read files.  Printf and friends now
+  have cord variants.  Cord traversals are a bit faster.
+- Made ALL_INTERIOR_POINTERS recognition the default.
+- Fixed de so that it can run in constant space, independent
+  of file size.  Added simple string searching to cords and de.
+- Added the Hull-Ellis C++ interface.
+- Added dynamic library support for OSF/1.
+  (Thanks to Al Dosser and Tim Bingham at DEC.)
+- Changed argument to GC_expand_hp to be expressed
+  in units of bytes instead of heap blocks.  (Necessary
+  since the heap block size now varies depending on
+  configuration.  The old version was never very clean.)
+- Added GC_get_heap_size().  The previous "equivalent"
+  was broken.
+- Restructured the Makefile a bit.  
+
+Since version 4.0:
+- Changed finalization implementation to guarantee that
+  finalization procedures are called outside of the allocation
+  lock, making direct use of the interface a little less dangerous.
+  MAY BREAK EXISTING CLIENTS that assume finalizers
+  are protected by a lock.  Since there seem to be few multithreaded
+  clients that use finalization, this is hopefully not much of
+  a problem.
+- Fixed a gross bug in CORD_prev.
+- Fixed a bug in blacklst.c that could result in unbounded
+  heap growth during startup on machines that do not clear
+  memory obtained from the OS (e.g. win32S).
+- Ported de editor to win32/win32S.  (This is now the only
+  version with a mouse-sensitive UI.)
+- Added GC_malloc_ignore_off_page to allocate large arrays
+  in the presence of ALL_INTERIOR_POINTERS.
+- Changed GC_call_with_alloc_lock to not disable signals in
+  the single-threaded case.
+- Reduced retry count in GC_collect_or_expand for garbage
+  collecting when out of memory.
+- Made uncollectable allocations bypass black-listing, as they
+  should.
+- Fixed a bug in typed_test in test.c that could cause (legitimate)
+  GC crashes.
+- Fixed some potential synchronization problems in finalize.c
+- Fixed a real locking problem in typd_mlc.c.
+- Worked around an AIX 3.2 compiler feature that results in
+  out of bounds memory references.
+- Partially worked around an IRIX5.2 beta problem (which may
+  or may not persist to the final release).
+- Fixed a bug in the heap integrity checking code that could
+  result in explicitly deallocated objects being identified as
+  smashed.  Fixed a bug in the dbg_mlc stack saving code
+  that caused old argument pointers to be considered live.
+- Fixed a bug in CORD_ncmp (and hence CORD_str).
+- Repaired the OS2 port, which had suffered from bit rot
+  in 4.0.  Worked around what appears to be CSet/2 V1.0
+  optimizer bug.
+- Fixed a Makefile bug for target "c++".
+
+Since version 4.1:
+- Multiple bug fixes/workarounds in the Solaris threads version.
+  (It occasionally failed to locate some register contents for
+  marking.  It also turns out that thr_suspend and friends are
+  unreliable in Solaris 2.3.  Dirty bit reads appear
+  to be unreliable under some weird 
+  circumstances.  My stack marking code
+  contained a serious performance bug.  The new code is
+  extremely defensive, and has not failed in several cpu
+  hours of testing.  But  no guarantees ...)
+- Added MacOS support (thanks to Patrick Beard.)
+- Fixed several syntactic bugs in gc_c++.h and friends.  (These
+  didn't bother g++, but did bother most other compilers.)
+  Fixed gc_c++.h finalization interface.  (It didn't.)
+- 64 bit alignment for allocated objects was not guaranteed in a
+  few cases in which it should have been.
+- Added GC_malloc_atomic_ignore_off_page.
+- Added GC_collect_a_little.
+- Added some prototypes to gc.h.
+- Some other minor bug fixes (notably in Makefile).
+- Fixed OS/2 / EMX port (thanks to Ari Huttunen).
+- Fixed AmigaDOS port. (thanks to Michel Schinz).
+- Fixed the DATASTART definition under Solaris.  There
+  was a 1 in 16K chance of the collector missing the first
+  64K of static data (and thus crashing).
+- Fixed some blatant anachronisms in the README file.
+- Fixed PCR-Makefile for upcoming PPCR release.
+
+Since version 4.2:
+- Fixed SPARC alignment problem with GC_DEBUG.
+- Fixed Solaris threads /proc workaround.  The real
+  problem was an interaction with mprotect.
+- Incorporated fix from Patrick Beard for gc_c++.h (now gc_cpp.h).
+- Slightly improved allocator space utilization by
+  fixing the GC_size_map mechanism.
+- Integrated some Sony News and MIPS RISCos 4.51
+  patches.  (Thanks to Nobuyuki Hikichi of
+  Software Research Associates, Inc. Japan)
+- Fixed HP_PA alignment problem.  (Thanks to
+  xjam@cork.cs.berkeley.edu.)
+- Added GC_same_obj and friends.  Changed GC_base
+  to return 0 for pointers past the end of large objects.
+  Improved GC_base performance with ALL_INTERIOR_POINTERS
+  on machines with a slow integer mod operation.
+  Added GC_PTR_ADD, GC_PTR_STORE, etc. to prepare
+  for preprocessor.
+- changed the default on most UNIX machines to be that
+  signals are not disabled during critical GC operations.
+  This is still ANSI-conforming, though somewhat dangerous
+  in the presence of signal handlers. But the performance
+  cost of the alternative is sometimes problematic.
+  Can be changed back with a minor Makefile edit.
+- renamed IS_STRING in gc.h, to CORD_IS_STRING, thus
+  following my own naming convention.  Added the function
+  CORD_to_const_char_star.
+- Fixed a gross bug in GC_finalize.  Symptom: occasional
+  address faults in that function.  (Thanks to Anselm
+  Baird-Smith (Anselm.BairdSmith@inria.fr)
+- Added port to ICL DRS6000 running DRS/NX.  Restructured
+  things a bit to factor out common code, and remove obsolete
+  code.  Collector should now run under SUNOS5 with either
+  mprotect or /proc dirty bits.  (Thanks to Douglas Steel
+  (doug@wg.icl.co.uk)).
+- More bug fixes and workarounds for Solaris 2.X.  (These were
+  mostly related to putting the collector in a dynamic library,
+  which didn't really work before.  Also SOLARIS_THREADS
+  didn't interact well with dl_open.)  Thanks to btlewis@eng.sun.com.
+- Fixed a serious performance bug on the DEC Alpha.  The text
+  segment was getting registered as part of the root set.
+  (Amazingly, the result was still fast enough that the bug
+  was not conspicuous.) The fix works on OSF/1, version 1.3.
+  Hopefully it also works on other versions of OSF/1 ...
+- Fixed a bug in GC_clear_roots.
+- Fixed a bug in GC_generic_malloc_words_small that broke
+  gc_inl.h.  (Reported by Antoine de Maricourt.  I broke it
+  in trying to tweak the Mac port.) 
+- Fixed some problems with cord/de under Linux.
+- Fixed some cord problems, notably with CORD_riter4.
+- Added DG/UX port.
+  Thanks to Ben A. Mesander (ben@piglet.cr.usgs.gov)
+- Added finalization registration routines with weaker ordering
+  constraints.  (This is necessary for C++ finalization with
+  multiple inheritance, since the compiler often adds self-cycles.)
+- Filled the holes in the SCO port. (Thanks to Michael Arnoldus
+  <chime@proinf.dk>.)
+- John Ellis' additions to the C++ support:  From John:
+
+* I completely rewrote the documentation in the interface gc_c++.h
+(later renamed gc_cpp.h).  I've tried to make it both clearer and more
+precise.
+
+* The definition of accessibility now ignores pointers from an
+finalizable object (an object with a clean-up function) to itself.
+This allows objects with virtual base classes to be finalizable by the
+collector.  Compilers typically implement virtual base classes using
+pointers from an object to itself, which under the old definition of
+accessibility prevented objects with virtual base classes from ever
+being collected or finalized.
+
+* gc_cleanup now includes gc as a virtual base.  This was enabled by
+the change in the definition of accessibility.
+
+* I added support for operator new[].  Since most (all?) compilers
+don't yet support operator new[], it is conditionalized on
+-DOPERATOR_NEW_ARRAY.  The code is untested, but its trivial and looks
+correct.
+
+* The test program test_gc_c++ (later renamed test_cpp.cc)
+tries to test for the C++-specific functionality not tested by the
+other programs.
+- Added <unistd.h> include to misc.c.  (Needed for ppcr.)
+- Added PowerMac port. (Thanks to Patrick Beard again.)
+- Fixed "srcdir"-related Makefile problems.  Changed things so
+  that all externally visible include files always appear in the
+  include subdirectory of the source.  Made gc.h directly
+  includable from C++ code.  (These were at Per
+  Bothner's suggestion.)
+- Changed Intel code to also mark from ebp (Kevin Warne's
+  suggestion).
+- Renamed C++ related files so they could live in a FAT
+  file system. (Charles Fiterman's suggestion.)
+- Changed Windows NT Makefile to include C++ support in
+  gc.lib.  Added C++ test as Makefile target.
+  
+Since version 4.3:
+ - ASM_CLEAR_CODE was erroneously defined for HP
+   PA machines, resulting in a compile error.
+ - Fixed OS/2 Makefile to create a library.  (Thanks to
+   Mark Boulter (mboulter@vnet.ibm.com)).
+ - Gc_cleanup objects didn't work if they were created on
+   the stack.  Fixed.
+ - One copy of Gc_cpp.h in the distribution was out of 
+   synch, and failed to document some known compiler
+   problems with explicit destructor invocation.  Partially
+   fixed.  There are probably other compilers on which
+   gc_cleanup is miscompiled.
+ - Fixed Makefile to pass C compiler flags to C++ compiler.
+ - Added Mac fixes.
+ - Fixed os_dep.c to work around what appears to be
+   a new and different VirtualQuery bug under newer
+   versions of win32S.
+ - GC_non_gc_bytes was not correctly maintained by
+   GC_free.  Fixed.  Thanks to James Clark (jjc@jclark.com).
+ - Added GC_set_max_heap_size.
+ - Changed allocation code to ignore blacklisting if it is preventing
+   use of a very large block of memory.  This has the advantage
+   that naive code allocating very large objects is much more
+   likely to work.  The downside is you might no
+   longer find out that such code should really use
+   GC_malloc_ignore_off_page.
+ - Changed GC_printf under win32 to close and reopen the file
+   between calls.  FAT file systems otherwise make the log file
+   useless for debugging.
+ - Added GC_try_to_collect and GC_get_bytes_since_gc.  These
+   allow starting an abortable collection during idle times. 
+   This facility does not require special OS support.  (Thanks to
+   Michael Spertus of Geodesic Systems for suggesting this.  It was
+   actually an easy addition.  Kumar Srikantan previously added a similar
+   facility to a now ancient version of the collector.  At the time
+   this was much harder, and the result was less convincing.)
+ - Added some support for the Borland development environment.  (Thanks
+   to John Ellis and Michael Spertus.)
+ - Removed a misfeature from checksums.c that caused unexpected 
+   heap growth.  (Thanks to Scott Schwartz.)
+ - Changed finalize.c to call WARN if it encounters a finalization cycle.
+   WARN is defined in gc_priv.h to write a message, usually to stdout.
+   In many environments, this may be inappropriate.
+ - Renamed NO_PARAMS in gc.h to GC_NO_PARAMS, thus adhering to my own
+   naming convention.
+ - Added GC_set_warn_proc to intercept warnings.
+ - Fixed Amiga port. (Thanks to Michel Schinz (schinz@alphanet.ch).)
+ - Fixed a bug in mark.c that could result in an access to unmapped
+   memory from GC_mark_from_mark_stack on machines with unaligned
+   pointers.
+ - Fixed a win32 specific performance bug that could result in scanning of
+   objects allocated with the system malloc.
+ - Added REDIRECT_MALLOC.
+
+Since version 4.4:
+ - Fixed many minor and one major README bugs. (Thanks to Franklin Chen
+   (chen@adi.com) for pointing out many of them.)
+ - Fixed ALPHA/OSF/1 dynamic library support. (Thanks to Jonathan Bachrach
+   (jonathan@harlequin.com)).
+ - Added incremental GC support (MPROTECT_VDB) for Linux (with some
+   help from Bruno Haible).
+ - Altered SPARC recognition tests in gc.h and config.h (mostly as
+   suggested by Fergus Henderson).
+ - Added basic incremental GC support for win32, as implemented by
+   Windows NT and Windows 95.  GC_enable_incremental is a noop
+   under win32s, which doesn't implement enough of the VM interface.
+ - Added -DLARGE_CONFIG.
+ - Fixed GC_..._ignore_off_page to also function without
+   -DALL_INTERIOR_POINTERS.
+ - (Hopefully) fixed RS/6000 port.  (Only the test was broken.)
+ - Fixed a performance bug in the nonincremental collector running
+   on machines supporting incremental collection with MPROTECT_VDB
+   (e.g. SunOS 4, DEC AXP).  This turned into a correctness bug under
+   win32s with win32 incremental collection.  (Not all memory protection
+   was disabled.)
+ - Fixed some ppcr related bit rot.
+ - Caused dynamic libraries to be unregistered before reregistering.
+   The old way turned out to be a performance bug on some machines.
+ - GC_root_size was not properly maintained under MSWIN32.
+ - Added -DNO_DEBUGGING and GC_dump.
+ - Fixed a couple of bugs arising with SOLARIS_THREADS +
+   REDIRECT_MALLOC.
+ - Added NetBSD/M68K port.  (Thanks to Peter Seebach
+   <seebs@taniemarie.solon.com>.)
+ - Fixed a serious realloc bug.  For certain object sizes, the collector
+   wouldn't scan the expanded part of the object.  (Thanks to Clay Spence
+   (cds@peanut.sarnoff.com) for noticing the problem, and helping me to
+   track it down.)
+   
+Since version 4.5:
+ - Added Linux ELF support.  (Thanks to Arrigo Triulzi <arrigo@ic.ac.uk>.)
+ - GC_base crashed if it was called before any other GC_ routines.
+   This could happen if a gc_cleanup object was allocated outside the heap
+   before any heap allocation.
+ - The heap expansion heuristic was not stable if all objects had finalization
+   enabled.  Fixed finalize.c to count memory in finalization queue and
+   avoid explicit deallocation.  Changed alloc.c to also consider this count.
+   (This is still not recommended.  It's expensive if nothing else.)  Thanks
+   to John Ellis for pointing this out.
+ - GC_malloc_uncollectable(0) was broken.  Thanks to Phong Vo for pointing
+   this out.
+ - The collector didn't compile under Linux 1.3.X.  (Thanks to Fred Gilham for
+   pointing this out.)  The current workaround is ugly, but expected to be
+   temporary.
+ - Fixed a formatting problem for SPARC stack traces.
+ - Fixed some '=='s in os_dep.c that should have been assignments.
+   Fortunately these were in code that should never be executed anyway.
+   (Thanks to Fergus Henderson.)
+ - Fixed the heap block allocator to only drop blacklisted blocks in small
+   chunks.  Made BL_LIMIT self adjusting.  (Both of these were in response
+   to heap growth observed by Paul Graham.)
+ - Fixed the Metrowerks/68K Mac code to also mark from a6.  (Thanks
+   to Patrick Beard.)
+ - Significantly updated README.debugging.
+ - Fixed some problems with longjmps out of signal handlers, especially under
+   Solaris.  Added a workaround for the fact that siglongjmp doesn't appear to
+   do the right thing with -lthread under Solaris.
+ - Added MSDOS/djgpp port.  (Thanks to Mitch Harris  (maharri@uiuc.edu).)
+ - Added "make reserved_namespace" and "make user_namespace".  The
+   first renames ALL "GC_xxx" identifiers as "_GC_xxx".  The second is the
+   inverse transformation.  Note that doing this is guaranteed to break all
+   clients written for the other names.
+ - descriptor field for kind NORMAL in GC_obj_kinds with ADD_BYTE_AT_END
+   defined should be -ALIGNMENT not WORDS_TO_BYTES(-1).  This is
+   a serious bug on machines with pointer alignment of less than a word.
+ - GC_ignore_self_finalize_mark_proc didn't handle pointers to very near the
+   end of the object correctly.  Caused failures of the C++ test on a DEC Alpha
+   with g++.
+ - gc_inl.h still had problems.  Partially fixed.  Added warnings at the
+   beginning to hopefully specify the remaining dangers.
+ - Added DATAEND definition to config.h.
+ - Fixed some of the .h file organization.  Fixed "make floppy".
+Since version 4.6:
+ - Fixed some compilation problems with -DCHECKSUMS (thanks to Ian Searle)
+ - Updated some Mac specific files to synchronize with Patrick Beard.
+ - Fixed a serious bug for machines with non-word-aligned pointers.
+   (Thanks to Patrick Beard for pointing out the problem.  The collector
+   should fail almost any conceivable test immediately on such machines.)
+
+Since version 4.7:
+ - Changed a "comment" in a MacOS specific part of mach-dep.c that caused
+   gcc to fail on other platforms.
+
+Since version 4.8
+ - More README.debugging fixes.
+ - Objects ready for finalization, but not finalized in the same GC
+   cycle, could be prematurely collected.  This occasionally happened
+   in test_cpp.
+ - Too little memory was obtained from the system for very large
+   objects.  That could cause a heap explosion if these objects were
+   not contiguous (e.g. under PCR), and too much of them was blacklisted.
+ - Due to an improper initialization, the collector was too hesitant to
+   allocate blacklisted objects immediately after system startup.
+ - Moved GC_arrays from the data into the bss segment by not explicitly
+   initializing it to zero.  This significantly
+   reduces the size of executables, and probably avoids some disk accesses
+   on program startup.  It's conceivable that it might break a port that I
+   didn't test.
+ - Fixed EMX_MAKEFILE to reflect the gc_c++.h to gc_cpp.h renaming which
+   occurred a while ago.
+
+Since 4.9:
+ - Fixed a typo around a call to GC_collect_or_expand in alloc.c.  It broke
+   handling of out of memory.  (Thanks to Patrick Beard for noticing.)
+
+Since 4.10:
+ - Rationalized (hopefully) GC_try_to_collect in an incremental collection
+   environment.  It appeared to not handle a call while a collection was in
+   progress, and was otherwise too conservative.
+ - Merged GC_reclaim_or_delete_all into GC_reclaim_all to get rid of some
+   code.
+ - Added Patrick Beard's Mac fixes, with substantial completely untested
+   modifications.
+ - Fixed the MPROTECT_VDB code to deal with large pages and imprecise
+   fault addresses (as on an UltraSPARC running Solaris 2.5).  Note that this
+   was not a problem in the default configuration, which uses PROC_VDB.
+ - The DEC Alpha assembly code needed to restore $gp between calls.
+   Thanks to Fergus Henderson for tracking this down and supplying a
+   patch.
+ - The write command for "de" was completely broken for large files.
+   I used the easiest portable fix, which involved changing the semantics
+   so that f.new is written instead of overwriting f.  That's safer anyway.
+ - Added README.solaris2 with a discussion of the possible problems of
+   mixing the collector's sbrk allocation with malloc/realloc.
+ - Changed the data segment starting address for SGI machines.  The
+   old code failed under IRIX6.
+ - Required double word alignment for MIPS.
+ - Various minor fixes to remove warnings.
+ - Attempted to fix some Solaris threads problems reported by Zhiying Chen.
+   In particular, the collector could try to fork a thread with the
+   world stopped as part of GC_thr_init.  It also failed to deal with
+   the case in which the original thread terminated before the whole
+   process did.
+ - Added -DNO_EXECUTE_PERMISSION.  This has a major performance impact
+   on the incremental collector under Irix, and perhaps under other
+   operating systems.
+ - Added some code to support allocating the heap with mmap.  This may
+   be preferable under some circumstances.
+ - Integrated dynamic library support for HP.
+   (Thanks to Knut Tvedten <knuttv@ifi.uio.no>.)
+ - Integrated James Clark's win32 threads support, and made a number
+   of changes to it, many of which were suggested by Pontus Rydin.
+   This is still not 100% solid.
+ - Integrated Alistair Crooks' support for UTS4 running on an Amdahl
+   370-class machine.
+ - Fixed a serious bug in explicitly typed allocation.  Objects requiring
+   large descriptors where handled in a way that usually resulted in
+   a segmentation fault in the marker.  (Thanks to Jeremy Fitzhardinge
+   for helping to track this down.)
+ - Added partial support for GNU win32 development.  (Thanks to Fergus
+   Henderson.)
+ - Added optional support for Java-style finalization semantics.  (Thanks
+   to Patrick Bridges.)  This is recommended only for Java implementations.
+ - GC_malloc_uncollectable faulted instead of returning 0 when out of
+   memory.  (Thanks to dan@math.uiuc.edu for noticing.)
+ - Calls to GC_base before the collector was initialized failed on a
+   DEC Alpha.  (Thanks to Matthew Flatt.)
+ - Added base pointer checking to GC_REGISTER_FINALIZER in debugging
+   mode, at the suggestion of Jeremy Fitzhardinge.
+ - GC_debug_realloc failed for uncollectable objects.  (Thanks to
+   Jeremy Fitzhardinge.)
+ - Explicitly typed allocation could crash if it ran out of memory.
+   (Thanks to Jeremy Fitzhardinge.)
+ - Added minimal support for a DEC Alpha running Linux.
+ - Fixed a problem with allocation of objects whose size overflowed
+   ptrdiff_t.  (This now fails unconditionally, as it should.)
+ - Added the beginning of Irix pthread support.
+ - Integrated Xiaokun Zhu's fixes for djgpp 2.01.
+ - Added SGI-style STL allocator support (gc_alloc.h).
+ - Fixed a serious bug in README.solaris2.  Multithreaded programs must include
+   gc.h with SOLARIS_THREADS defined.
+ - Changed GC_free so it actually deallocates uncollectable objects.
+   (Thanks to Peter Chubb for pointing out the problem.)
+ - Added Linux ELF support for dynamic libararies.  (Thanks again to
+   Patrick Bridges.)
+ - Changed the Borland cc configuration so that the assembler is not
+   required.
+ - Fixed a bug in the C++ test that caused it to fail in 64-bit
+   environments.
+
+Since 4.11:
+ - Fixed ElfW definition in dyn_load.c. (Thanks to Fergus Henderson.)
+   This prevented the dynamic library support from compiling on some
+   older ELF Linux systems.
+ - Fixed UTS4 port (which I apparently mangled during the integration)
+   (Thanks to again to Alistair Crooks.)
+ - "Make C++" failed on Suns with SC4.0, due to a problem with "bool".
+   Fixed in gc_priv.h.
+ - Added more pieces for GNU win32.  (Thanks to Timothy N. Newsham.)
+   The current state of things should suffice for at least some
+   applications.
+ - Changed the out of memory retry count handling as suggested by
+   Kenjiro Taura.  (This matters only if GC_max_retries > 0, which
+   is no longer the default.)
+ - If a /proc read failed repeatedly, GC_written_pages was not updated
+   correctly.  (Thanks to Peter Chubb for diagnosing this.)
+ - Under unlikely circumstances, the allocator could infinite loop in
+   an out of memory situation.  (Thanks again to Kenjiro Taura for
+   identifying the problem and supplying a fix.)
+ - Fixed a syntactic error in the DJGPP code.  (Thanks to Fergus
+   Henderson for finding this by inspection.)  Also fixed a test program
+   problem with DJGPP (Thanks to Peter Monks.)
+ - Atomic uncollectable objects were not treated correctly by the
+   incremental collector.  This resulted in weird log statistics and
+   occasional performance problems.  (Thanks to Peter Chubb for pointing
+   this out.)
+ - Fixed some problems resulting from compilers that dont define
+   __STDC__.  In this case void * and char * were used inconsistently
+   in some cases.  (Void * should not have been used at all.  If
+   you have an ANSI superset compiler that does not define __STDC__,
+   please compile with -D__STDC__=0. Thanks to Manuel Serrano and others
+   for pointing out the problem.)
+ - Fixed a compilation problem on Irix with -n32 and -DIRIX_THREADS.
+   Also fixed some other IRIX_THREADS problems which may or may not have
+   had observable symptoms.
+ - Fixed an HP PA compilation problem in dyn_load.c.  (Thanks to
+   Philippe Queinnec.)
+ - SEGV fault handlers sometimes did not get reset correctly.  (Thanks
+   to David Pickens.)
+ - Added a fix for SOLARIS_THREADS on Intel.  (Thanks again to David
+   Pickens.)  This probably needs more work to become functional.
+ - Fixed struct sigcontext_struct in os_dep.c for compilation under
+   Linux 2.1.X.        (Thanks to Fergus Henderson.)
+ - Changed the DJGPP STACKBOTTOM and DATASTART values to those suggested
+   by Kristian Kristensen.  These may still not be right, but it is
+   it is likely to work more often than what was there before.  They may
+   even be exactly right.
+ - Added a #include <string.h> to test_cpp.cc.  This appears to help
+   with HP/UX and gcc.  (Thanks to assar@sics.se.)
+ - Version 4.11 failed to run in incremental mode on recent 64-bit Irix
+   kernels.  This was a problem related to page unaligned heap segments.
+   Changed the code to page align heap sections on all platforms.
+   (I had mistakenly identified this as a kernel problem earlier.
+   It was not.)
+ - Version 4.11 did not make allocated storage executable, except on
+   one or two platforms, due to a bug in a #if test.  (Thanks to Dave
+   Grove for pointing this out.)
+ - Added sparc_sunos4_mach_dep.s to support Sun's compilers under SunOS4.
+ - Added GC_exclude_static_roots.
+ - Fixed the object size mapping algorithm.  This shouldn't matter,
+   but the old code was ugly.
+ - Heap checking code could die if one of the allocated objects was
+   larger than its base address.  (Unsigned underflow problem.  Thanks
+   to Clay Spence for isolating the problem.)
+ - Added RS6000 (AIX) dynamic library support and fixed STACK_BOTTOM.
+   (Thanks to Fred Stearns.)
+ - Added Fergus Henderson's patches for improved robustness with large
+   heaps and lots of blacklisting.
+ - Added Peter Chubb's changes to support Solaris Pthreads, to support
+   MMAP allocation in Solaris, to allow Solaris to find dynamic libraries
+   through /proc, to add malloc_typed_ignore_off_page, and a few other
+   minor features and bug fixes.
+ - The Solaris 2 port should not use sbrk.  I received confirmation from
+   Sun that the use of sbrk and malloc in the same program is not
+   supported.  The collector now defines USE_MMAP by default on Solaris.
+ - Replaced the djgpp makefile with Gary Leavens' version.
+ - Fixed MSWIN32 detection test.
+ - Added Fergus Henderson's patches to allow putting the collector into
+   a DLL under GNU win32.
+ - Added Ivan V. Demakov's port to Watcom C on X86.
+ - Added Ian Piumarta's Linux/PowerPC port.
+ - On Brian Burton's suggestion added PointerFreeGC to the placement
+   options in gc_cpp.h.  This is of course unsafe, and may be controversial.
+   On the other hand, it seems to be needed often enough that it's worth
+   adding as a standard facility.
+
+Since 4.12:
+ - Fixed a crucial bug in the Watcom port.  There was a redundant decl
+   of GC_push_one in gc_priv.h.
+ - Added FINALIZE_ON_DEMAND.
+ - Fixed some pre-ANSI cc problems in test.c.
+ - Removed getpagesize() use for Solaris.  It seems to be missing in one
+   or two versions.
+ - Fixed bool handling for SPARCCompiler version 4.2.
+ - Fixed some files in include that had gotten unlinked from the main
+   copy.
+ - Some RS/6000 fixes (missing casts).  Thanks to Toralf Foerster.
+ - Fixed several problems in GC_debug_realloc, affecting mostly the
+   FIND_LEAK case.
+ - GC_exclude_static_roots contained a buggy unsigned comparison to
+   terminate a loop.  (Thanks to Wilson Ho.)
+ - CORD_str failed if the substring occurred at the last possible position.
+   (Only affects cord users.)
+ - Fixed Linux code to deal with RedHat 5.0 and integrated Peter Bigot's
+   os_dep.c code for dealing with various Linux versions.
+ - Added workaround for Irix pthreads sigaction bug and possible signal
+   misdirection problems.
+Since alpha1:
+ - Changed RS6000 STACKBOTTOM.
+ - Integrated Patrick Beard's Mac changes.
+ - Alpha1 didn't compile on Irix m.n, m < 6.
+ - Replaced Makefile.dj with a new one from Gary Leavens.
+ - Added Andrew Stitcher's changes to support SCO OpenServer.
+ - Added PRINT_BLACK_LIST, to allow debugging of high densities of false
+   pointers.
+ - Added code to debug allocator to keep track of return address
+   in GC_malloc caller, thus giving a bit more context.
+ - Changed default behavior of large block allocator to more
+   aggressively avoid fragmentation.  This is likely to slow down the
+   collector when it succeeds at reducing space cost.
+ - Integrated Fergus Henderson's CYGWIN32 changes.  They are untested,
+   but needed for newer versions.
+ - USE_MMAP had some serious bugs.  This caused the collector to fail
+   consistently on Solaris with -DSMALL_CONFIG.
+ - Added Linux threads support, thanks largely to Fergus Henderson.
+Since alpha2:
+ - Fixed more Linux threads problems.
+ - Changed default GC_free_space_divisor to 3 with new large block allocation.
+   (Thanks to Matthew Flatt for some measurements that suggest the old
+   value sometimes favors space too much over time.)
+ - More CYGWIN32 fixes.
+ - Integrated Tyson-Dowd's Linux-M68K port.
+ - Minor HP PA and DEC UNIX fixes from Fergus Henderson.
+ - Integrated Christoffe Raffali's Linux-SPARC changes.
+ - Allowed for one more GC fixup iteration after a full GC in incremental
+   mode.  Some quick measurements suggested that this significantly
+   reduces pause times even with smaller GC_RATE values.
+ - Moved some more GC data structures into GC_arrays.  This decreases
+   pause times and GC overhead, but makes debugging slightly less convenient.
+ - Fixed namespace pollution problem ("excl_table").
+ - Made GC_incremental a constant for -DSMALL_CONFIG, hopefully shrinking
+   that slightly.
+ - Added some win32 threads fixes.
+ - Integrated Ivan Demakov and David Stes' Watcom fixes.
+ - Various other minor fixes contributed by many people.
+ - Renamed config.h to gcconfig.h, since config.h tends to be used for
+   many other things.
+ - Integrated Matthew Flatt's support for 68K MacOS "far globals".
+ - Fixed up some of the dynamic library Makefile targets for consistency
+   across platforms.
+ - Fixed a USE_MMAP typo that caused out-of-memory handling to fail
+   on Solaris.
+ - Added code to test.c to test thread creation a bit more.
+ - Integrated GC_win32_free_heap, as suggested by Ivan Demakov.
+ - Fixed Solaris 2.7 stack base finding problem.  (This may actually
+   have been done in an earlier alpha release.)
+Since alpha3:
+ - Fixed MSWIN32 recognition test, which interfered with cygwin.
+ - Removed unnecessary gc_watcom.asm from distribution.  Removed
+   some obsolete README.win32 text.
+ - Added Alpha Linux incremental GC support.  (Thanks to Philipp Tomsich
+   for code for retrieving the fault address in a signal handler.)
+   Changed Linux signal handler context argument to be a pointer.
+ - Took care of some new warnings generated by the 7.3 SGI compiler.
+ - Integrated Phillip Musumeci's FreeBSD/ELF fixes.
+ - -DIRIX_THREADS was broken with the -o32 ABI (typo in gc_priv.h>
+
+Since 4.13:
+ - Fixed GC_print_source_ptr to not use a prototype.
+ - generalized CYGWIN test.
+ - gc::new did the wrong thing with PointerFreeGC placement.
+   (Thanks to Rauli Ruohonen.)
+ - In the ALL_INTERIOR_POINTERS (default) case, some callee-save register
+   values could fail to be scanned if the register was saved and
+   reused in a GC frame.  This showed up in verbose mode with gctest
+   compiled with an unreleased SGI compiler.  I vaguely recall an old
+   bug report that may have been related.  The bug was probably quite old.
+   (The problem was that the stack scanning could be deferred until
+   after the relevant frame was overwritten, and the new save location
+   might be outside the scanned area.  Fixed by more eager stack scanning.)
+ - PRINT_BLACK_LIST had some problems.  A few source addresses were garbage.
+ - Replaced Makefile.dj and added -I flags to cord make targets.
+   (Thanks to Gary Leavens.)
+ - GC_try_to_collect was broken with the nonincremental collector.
+ - gc_cleanup destructors could pass the wrong address to
+   GC_register_finalizer_ignore_self in the presence of multiple
+   inheritance.  (Thanks to Darrell Schiebel.)
+ - Changed PowerPC Linux stack finding code.
+
+Since 4.14alpha1
+ - -DSMALL_CONFIG did not work reliably with large (> 4K) pages.
+   Recycling the mark stack during expansion could result in a size
+   zero heap segment, which confused things.  (This was probably also an
+   issue with the normal config and huge pages.)
+ - Did more work to make sure that callee-save registers were scanned
+   completely, even with the setjmp-based code.  Added USE_GENERIC_PUSH_REGS
+   macro to facilitate testing on machines I have access to.
+ - Added code to explicitly push register contents for win32 threads.
+   This seems to be necessary.  (Thanks to Pierre de Rop.)
+
+Since 4.14alpha2
+ - changed STACKBOTTOM for DJGPP (Thanks to Salvador Eduardo Tropea).
+Since 4.14
+ - Reworked large block allocator.  Now uses multiple doubly linked free
+   lists to approximate best fit.
+ - Changed heap expansion heuristic.  Entirely free blocks are no longer
+   counted towards the heap size.  This seems to have a major impact on
+   heap size stability; the old version could expand the heap way too
+   much in the presence of large block fragmentation.
+ - added -DGC_ASSERTIONS and some simple assertions inside the collector.
+   This is mainlyt for collector debugging.
+ - added -DUSE_MUNMAP to allow the heap to shrink.  Suupported on only
+   a few UNIX-like platforms for now.
+ - added GC_dump_regions() for debugging of fragmentation issues.
+ - Changed PowerPC pointer alignment under Linux to 4.  (This needs
+   checking by someone who has one.  The suggestions came to me via a
+   rather circuitous path.)
+ - Changed the Linux/Alpha port to walk the data segment backwards until
+   it encounters a SIGSEGV.  The old way to find the start of the data
+   segment broke with a recent release.
+ - cordxtra.c needed to call GC_REGISTER_FINALIZER instead of
+   GC_register_finalizer, so that it would continue to work with GC_DEBUG.
+ - allochblk sometimes cleared the wrong block for debugging purposes
+   when it dropped blacklisted blocks.  This could result in spurious
+   error reports with GC_DEBUG.
+ - added MACOS X Server support.  (Thanks to Andrew Stone.)
+ - Changed the Solaris threads code to ignore stack limits > 8 MB with
+   a warning.  Empirically, it is not safe to access arbitrary pages
+   in such large stacks.  And the dirty bit implementation does not
+   guarantee that none of them will be accessed.
+ - Integrated Martin Tauchmann's Amiga changes.
+ - Integrated James Dominy's OpenBSD/SPARC port.
+
+Since 5.0alpha1
+ - Fixed bugs introduced in alpha1 (OpenBSD & large block initialization).
+ - Added -DKEEP_BACK_PTRS and backptr.h interface.  (The implementation
+   idea came from Al Demers.)
+
+Since 5.0alpha2
+ - Added some highly incomplete code to support a copied young generation.
+   Comments on nursery.h are appreciated.
+ - Changed -DFIND_LEAK, -DJAVA_FINALIZATION, and -DFINALIZE_ON_DEMAND,
+   so the same effect could be obtained with a runtime switch.   This is
+   a step towards standardizing on a single dynamic GC library.
+ - Significantly changed the way leak detection is handled, as a consequence
+   of the above.
+
+Since 5.0 alpha3
+ - Added protection fault handling patch for Linux/M68K from Fergus
+   Henderson and Roman Hodek.
+ - Removed the tests for SGI_SOURCE in new_gc_alloc.h.  This was causing that
+   interface to fail on nonSGI platforms.
+ - Changed the Linux stack finding code to use /proc, after changing it
+   to use HEURISTIC1.  (Thanks to David Mossberger for pointing out the
+   /proc hook.)
+ - Added HP/UX incremental GC support and HP/UX 11 thread support.
+   Thread support is currently still flakey.
+ - Added basic Linux/IA64 support.
+ - Integrated Anthony Green's PicoJava support.
+ - Integrated Scott Ananian's StrongARM/NetBSD support.
+ - Fixed some fairly serious performance bugs in the incremental
+   collector.  These have probably been there essentially forever.
+   (Mark bits were sometimes set before scanning dirty pages.
+   The reclaim phase unnecessarily dirtied full small object pages.)
+ - Changed the reclaim phase to ignore nearly full pages to avoid
+   touching them.
+ - Limited GC_black_list_spacing to roughly the heap growth increment.
+ - Changed full collection triggering heuristic to decrease full GC
+   frequency by default, but to explicitly trigger full GCs during
+   heap growth.  This doesn't always improve things, but on average it's
+   probably a win.
+ - GC_debug_free(0, ...) failed.  Thanks to Fergus Henderson for the
+   bug report and fix.
+
+Since 5.0 alpha4
+ - GC_malloc_explicitly_typed and friends sometimes failed to
+   initialize first word.
+ - Added allocation routines and support in the marker for mark descriptors
+   in a type structure referenced by the first word of an object.  This was
+   introduced to support gcj, but hopefully in a way that makes it
+   generically useful.
+ - Added GC_requested_heapsize, and inhibited collections in nonincremental
+   mode if the actual used heap size is less than what was explicitly
+   requested.
+ - The Solaris pthreads version of GC_pthread_create didn't handle a NULL
+   attribute pointer.  Solaris thread support used the wrong default thread
+   stack size.  (Thanks to Melissa O'Neill for the patch.)
+ - Changed PUSH_CONTENTS macro to no longer modify first parameter.
+   This usually doesn't matter, but it was certainly an accident waiting
+   to happen ...
+ - Added GC_register_finalizer_no_order and friends to gc.h.  They're
+   needed by Java implementations.
+ - Integrated a fix for a win32 deadlock resulting from clock() calling
+   malloc.  (Thanks to Chris Dodd.)
+ - Integrated Hiroshi Kawashima's port to Linux/MIPS.  This was designed
+   for a handheld platform, and may or may not be sufficient for other
+   machines.
+ - Fixed a va_arg problem with the %c specifier in cordprnt.c.  It appears
+   that this was always broken, but recent versions of gcc are the first to
+   report the (statically detectable) bug.
+ - Added an attempt at a more general solution to dlopen races/deadlocks.
+   GC_dlopen now temporarily disables collection.  Still not ideal, but ...
+ - Added -DUSE_I686_PREFETCH, -DUSE_3DNOW_PREFETCH, and support for IA64
+   prefetch instructions.  May improve performance measurably, but I'm not
+   sure the code will run correctly on processors that don't support the
+   instruction.  Won't build except with very recent gcc.
+ - Added caching for header lookups in the marker.  This seems to result
+   in a barely measurable performance gain.  Added support for interleaved
+   lookups of two pointers, but unconfigured that since the performance
+   gain is currently near zero, and it adds to code size.
+ - Changed Linux DATA_START definition to check both data_start and
+   __data_start, since nothing else seems to be portable.
+ - Added -DUSE_LD_WRAP to optionally take advantage of the GNU ld function
+   wrapping mechanism.  Probably currently useful only on Linux.
+ - Moved some variables for the scratch allocator into GC_arrays, on
+   Martin Hirzel's suggestion.
+ - Fixed a win32 threads bug that caused the collector to not look for
+   interior pointers from one of the thread stacks without
+   ALL_INTERIOR_POINTERS.  (Thanks to Jeff Sturm.)
+ - Added Mingw32 support.  (Thanks again to Jeff Sturm for the patch.)
+ - Changed the alpha port to use the generic register scanning code instead
+   of alpha_mach_dep.s.  Alpha_mach_dep.s doesn't look for pointers in fp
+   registers, but gcc sometimes spills pointers there.  (Thanks to Manuel
+   Serrano for helping me debug this by email.)  Changed the IA64 code to
+   do something similar for similar reasons.
+
+[5.0alpha5 doesn't really exist, but it may have escaped.]
+
+Since 5.0alpha6:
+ - -DREDIRECT_MALLOC was broken in alpha6. Fixed.
+ - Cleaned up gc_ccp.h slightly, thus also causing the HP C++ compiler to
+   accept it.
+ - Removed accidental reference to dbg_mlc.c, which caused dbg_mlc.o to be
+   linked into every executable.
+ - Added PREFETCH to bitmap marker.  Changed it to use the header cache.
+ - GC_push_marked sometimes pushed one object too many, resulting in a
+   segmentation fault in GC_mark_from_mark_stack.  This was probably an old
+   bug.  It finally showed up in gctest on win32.
+ - Gc_priv.h erroneously #defined GC_incremental to be TRUE instead of FALSE
+   when SMALL_CONFIG was defined.  This was no doubt a major performance bug for
+   the default win32 configuration.
+ - Removed -DSMALL_CONFIG from NT_MAKEFILE.  It seemed like an anchronism now
+   that the average PC has 64MB or so.
+ - Integrated Bryce McKinley's patches for linux threads and dynamic loading
+   from the libgcj tree.  Turned on dynamic loading support for Linux/PPC.
+ - Changed the stack finding code to use environ on HP/UX.  (Thanks
+   to Gustavo Rodriguez-Rivera for the suggestion.)  This should probably
+   be done on other platforms, too.  Since I can't test those, that'll
+   wait until after 5.0.
+
+Since 5.0alpha7:
+ - Fixed threadlibs.c for linux threads.  -DUSE_LD_WRAP was broken and
+   -ldl was omitted.  Fixed Linux stack finding code to handle
+   -DUSE_LD_WRAP correctly.
+ - Added MSWIN32 exception handler around marker, so that the collector
+   can recover from root segments that are unmapped during the collection.
+   This caused occasional failures under Windows 98, and may also be
+   an issue under Windows NT/2000.
+
+Since 5.0
+ - Fixed a gc.h header bug which showed up under Irix.  (Thanks to
+   Dan Sullivan.)
+ - Fixed a typo in GC_double_descr in typd_mlc.c.
+   This probably could result in objects described by array descriptors not
+   getting traced correctly.  (Thanks to Ben Hutchings for pointing this out.)
+ - The block nearly full tests in reclaim.c were not correct for 64 bit
+   environments.  This could result in unnecessary heap growth under unlikely
+   conditions.
+
+Since 5.1
+ - dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it
+   was defined as a macro.  This prevented the collector from building on
+   Irix.
+ - We quietly assumed that indirect mark descriptors were never 0.
+   Our own typed allocation interface violated that.  This could result
+   in segmentation faults in the marker with typed allocation.
+ - Fixed a _DUSE_MUNMAP bug in the heap block allocation code.
+   (Thanks to Ben Hutchings for the patch.)
+ - Taught the collector about VC++ handling array operator new.
+   (Thanks again to Ben Hutchings for the patch.)
+ - The two copies of gc_hdrs.h had diverged.  Made one a link to the other
+   again.
+
+Since 5.2  (A few 5.2 patches are not in 6.0alpha1)
+ - Fixed _end declaration for OSF1.
+ - There were lots of spurious leak reports in leak detection mode, caused
+   by the fact that some pages were not being swept, and hence unmarked
+   objects weren't making it onto free lists.  (This bug dated back to 5.0.)
+ - Fixed a typo in the liblinuxgc.so Makefile rule.
+ - Added the GetExitCodeThread to Win32 GC_stop_world to (mostly) work
+   around a Windows 95 GetOpenFileName problem.  (Thanks to Jacob Navia.)
+
+Since 5.3
+ - Fixed a typo that prevented compilation with -DUSE_3DNOW_PREFETCH.
+   (Thanks to Shawn Wagner for actually testing this.)
+ - Fixed GC_is_thread_stack in solaris_threads.c.  It forgot to return a value
+   in the common case.  I wonder why nobody noticed?
+ - Fixed another silly syntax problem in GC_double_descr.  (Thanks to
+   Fergus Henderson for finding it.)
+ - Fixed a GC_gcj_malloc bug: It tended to release the allocator lock twice.
+
+Since 5.4  (A few 5.3 patches are not in 6.0alpha2)
+ - Added HP/PA prefetch support.
+ - Added -DDBG_HDRS_ALL and -DSHORT_DBG_HDRS to reduce the cost and improve
+   the reliability of generating pointer backtrace information, e.g. in
+   the Bigloo environment.
+ - Added parallel marking support (-DPARALLEL_MARK).  This currently
+   works only under IA32 and IA64 Linux, but it shouldn't be hard to adapt
+   to other platforms.  This is intended to be a lighter-weight (less
+   new code, probably not as scalable) solution than the work by Toshio Endo
+   et al, at the University of Tokyo.  A number of their ideas were
+   reused, though the code wasn't, and the underlying data structure
+   is significantly different.  In particular, we keep the global mark
+   stack as a single shared data structure, but most of the work is done
+   on smaller thread-local mark stacks.
+ - Changed GC_malloc_many to be cheaper, and to require less mutual exclusion
+   with -DPARALLEL_MARK.
+ - Added full support for thread local allocation under Linux
+   (-DTHREAD_LOCAL_ALLOC).  This is a thin veneer on GC_malloc_many, and
+   should be easily portable to other platforms, especially those that
+   support pthreads.
+ - CLEAR_DOUBLE was not always getting invoked when it should have been.
+ - GC_gcj_malloc and friends used different out of memory handling than
+   everything else, probably because I forgot about one when I implemented
+   the other.  They now both call GC_oom_fn(), not GC_oom_action().
+ - Integrated Jakub Jelinek's fixes for Linux/SPARC.
+ - Moved GC_objfreelist, GC_aobjfreelist, and GC_words_allocd out of
+   GC_arrays, and separately registered the first two as excluded roots.
+   This makes code compiled with gc_inl.h less dependent on the
+   collector version.  (It would be nice to remove the inclusion of
+   gc_priv.h by gc_inl.h completely, but we're not there yet.  The
+   locking definitions in gc_priv.h are still referenced.)
+   This change was later coniditoned on SEPARATE_GLOBALS, which
+   is not defined by default, since it involves a performance hit.
+ - Register GC_obj_kinds separately as an excluded root region.  The
+   attempt to register it with GC_arrays was usually failing.  (This wasn't
+   serious, but seemed to generate some confusion.) 
+ - Moved backptr.h to gc_backptr.h.
+
+Since 6.0alpha1
+ - Added USE_MARK_BYTES to reduce the need for compare-and-swap on platforms
+   for which that's expensive.
+ - Fixed a locking bug ib GC_gcj_malloc and some locking assertion problems.
+ - Added a missing volatile to OR_WORD and renamed the parameter to
+   GC_compare_and_swap so it's not a C++ reserved word.  (Thanks to
+   Toshio Endo for pointing out both of those.)
+ - Changed Linux dynamic library registration code to look at /proc/self/maps
+   instead of the rld data structures when REDIRECT_MALLOC is defined.
+   Otherwise some of the rld data data structures may be prematurely garbage
+   collected.  (Thanks to Eric Benson for helping to track this down.)
+ - Fixed USE_LD_WRAP a bit more, so it should now work without threads.
+ - Renamed XXX_THREADS macros to GC_XXX_THREADS for namespace correctness.
+   Tomporarily added some backward compatibility definitions.  Renamed
+   USE_LD_WRAP to GC_USE_LD_WRAP.
+ - Many MACOSX POWERPC changes, some additions to the gctest output, and
+   a few minor generic bug fixes.  (Thanks to Dietmar Planitzer.)
+
+Since 6.0 alpha2
+ - Fixed the /proc/self/maps code to not seek, since that apparently is not
+   reliable across all interesting kernels.
+ - Fixed some compilation problems in the absence of PARALLEL_MARK
+   (introduced in alpha2).
+ - Fixed an algorithmic problem with PARALLEL_MARK.  If work needs to
+   be given back to the main mark "stack", the BOTTOM entries of the local
+   stack should be given away, not the top ones.  This has substantial
+   performance impact, especially for > 2 processors, from what I can tell.
+ - Extracted gc_lock.h from gc_priv.h.  This should eventually make it a
+   bit easier to avoid including gc_priv.h in clients.
+ - Moved all include files to include/ and removed duplicate links to the
+   same file.  The old scheme was a bad idea because it was too easy to get the
+   copies out of sync, and many systems don't support hard links.
+   Unfortunately, it's likely that I broke some of the non-Unix Makefiles in
+   the process, although I tried to update them appropriately.
+ - Removed the partial support for a copied nursery.  It's not clear that
+   this would be a tremendous win, since we don't consistently lose to
+   generational copying collectors.  And it would significantly complicate
+   many things.  May be reintroduced if/when it really turns out to win.
+ - Removed references to IRIX_JDK_THREADS, since I believe there never
+   were and never will be any clients.
+ - Added some code to linux_threads.c to possibly support HPUX threads
+   using the Linux code.  Unfortunately, it doesn't work yet, and is
+   currently disabled.
+ - Added support under Linux/X86 for saving the call chain, both in (debug)
+   objects for client debugging, and in GC_arrays._last_stack for GC
+   debugging.  This was previously supported only under Solaris.  It is
+   not enabled by default under X86, since it requires that code be compiled
+   to explicitly dave frame pointers on the call stack.  (With gcc this
+   currently happens by default, but is often turned off explicitly.)
+   To turn it on, define SAVE_CALL_CHAIN.
+Since 6.0 alpha3
+ - Moved up the detection of mostly full blocks to the initiatiation of the
+   sweep phase.  This eliminates some lock conention in the PARALLEL_MARK case,
+   as multiple threads try to look at mostly full blocks concurrently.
+ - Restored the code in GC_malloc_many that grabs a prefix of the global
+   free list.  This avoids the case in which every GC_malloc_many call
+   tries and fails to allocate a new heap block, and the returns a single
+   object from the global free list.
+ - Some minor fixes in new_hblk.c.  (Attempted to build free lists in order
+   of increasing addresses instead of decreasing addresses for cache performance
+   reasons.  But this seems to be only a very minor gain with -DEAGER_SWEEP,
+   and a loss in other cases.  So the change was backed out.)
+ - Fixed some of the documentation.  (Thanks in large part to Fergus
+   Henderson.)
+ - Fixed the Linux USE_PROC_FOR_LIBRARIES code to deal with apps that perform
+   large numbers of mmaps.  (Thanks to Eric Benson.)  Also fixed that code to
+   deal with short reads.
+ - Added GC_get_total_bytes(). 
+ - Fixed leak detection mode to avoid spurious messages under linuxthreads.
+   (This should also now be easy for the other supported threads packages.
+   But the code is tricky enough that I'm hesitant to do it without being able
+   to test.  Everything allocated in the GC thread support itself should be
+   explicitly deallocated.)
+ - Made it possible (with luck) to redirect malloc to GC_local_malloc.
+
+Since 6.0 alpha4
+ - Changed the definition of GC_pause in linux_threads.c to use a volatile
+   asm.  Some versions of gcc apparently optimize away writes to local volatile
+   variables.  This caused poor locking behaviour starting at about
+   4 processors.
+ - Added GC_start_blocking(), GC_end_blocking() calls and wrapper for sleep
+   to linux_threads.c.
+   The first two calls could be used to generally avoid sending GC signals to
+   blocked threads, avoiding both premature wakeups and unnecessary overhead.
+ - Fixed a serious bug in thread-local allocation.  At thread termination,
+   GC_free could get called on small integers.  Changed the code for thread
+   termination to more efficiently return left-over free-lists.
+ - Integrated Kjetil Matheussen's BeOS support.
+ - Rearranged the directory structure to create the doc and tests
+   subdirectories.
+ - Sort of integrated Eric Benson's patch for OSF1.  This provided basic
+   OSF1 thread support by suitably extending hpux_irix_threads.c.  Based
+   on earlier email conversations with David Butenhof, I suspect that it
+   will be more reliable in the long run to base this on linux_threads.c
+   instead.  Thus I attempted to patch up linux_threads.c based on Eric's code.
+   The result is almost certainly broken, but hopefully close enough that
+   someone with access to a machine can pick it up.
+ - Integrated lots of minor changes from the NetBSD distribution.  (These
+   were supplied by David Brownlee.  I'm not sure about the original
+   authors.)
+ - Hacked a bit more on the HP/UX thread-support in linux_threads.c.  It
+   now appears to work in the absence of incremental collection.  Renamed
+   hpux_irix_threads.c back to irix_threads.c, and removed the attempt to
+   support HPUX there.
+ - Changed gc.h to define _REENTRANT in cases in which it should already
+   have been defined. It is still safer to also define it on the command
+   line. 
+
+Since 6.0alpha5:
+ - Changed the definition of DATASTART on ALPHA and IA64, where data_start
+   and __data_start are not defined by earlier versions of glibc.  This might
+   need to be fixed on other platforms as well.
+ - Changed the way the stack base and backing store base are found on IA64.
+   This should now remain reliable on future kernels.  But since it relies
+   on /proc, it will no longer work in the simulated NUE environment.
+ - Made the call to random() in dbg_mlc.c with -DKEEP_BACK_PTRS dependent
+   on the OS.  On non-Unix systems, rand() should be used instead.  Handled
+   small RAND_MAX.  (Thanks to Peter Ross for pointing this out.)
+ - Fixed the cord make rules to create the cord subdirectory, if necessary.
+   (Thanks to Doug Moen.)
+ - Changed fo_object_size calculation in finalize.c.  Turned finalization
+   of nonheap object into a no-op.  Removed anachronism from GC_size()
+   implementation.
+ - Changed GC_push_dirty call in solaris_threads.c to GC_push_selected.
+   It was missed in a previous renaming. (Thanks to Vladimir Tsichevski
+   for pointing this out.)
+ - Arranged to not not mask SIGABRT in linux_threads.c.  (Thanks to Bryce
+   McKinlay.) 
+ - Added GC_no_dls hook for applications that want to register their own
+   roots.
+ - Integrated Kjetil Matheussen's Amiga changes.
+ - Added FREEBSD_STACKBOTTOM.  Changed the X86/FreeBSD port to use it.
+   (Thanks to Matthew Flatt.)
+ - Added pthread_detach interception for platforms supported by linux_threads.c
+   and irix_threads.c.  Should also be added for Solaris?
+ - Changed the USE_MMAP code to check for the case in which we got the
+   high end of the address space, i.e. mem_ptr + mem_sz == 0.  It appears
+   that this can happen under Solaris 7.  It seems to be allowed by what
+   I would claim is an oversight in the mmap specification.  (Thanks to Toshio
+   Endo for pointing out the problem.)
+ - Cleanup of linux_threads.c.  Some code was originally cloned from
+   irix_threads.c and now unnecessary.  Some comments were obviously wrong.
+ - (Mostly) fixed a longstanding problem with setting of dirty bits from
+   a signal handler.  In the presence of threads, dirty bits could get lost,
+   since the etting of a bit in the bit vector was not atomic with respect
+   to other updates.  The fix is 100% correct only for platforms for which
+   GC_test_and_set is defined.  The goal is to make that all platforms with
+   thread support.  Matters only if incremental GC and threads are both
+   enabled.
+ - made GC_all_interior_pointers (a.k.a. ALL_INTERIOR_POINTERS) an
+   initialization time, instead of build-time option.  This is a 
+   nontrivial, high risk change.  It should slow down the code measurably
+   only if MERGE_SIZES is not defined, which is a very nonstandard
+   configuration.   
+ - Added doc/README.environment, and implemented what it describes.  This
+   allows a number of additional configuration options to be set through
+   the environment.  It documents a few previously undocumented options.
+ - Integrated Eric Benson's leak testing improvements.
+ - Removed the option to throw away the beginning of each page (DISCARD_WORDS).
+   This became less and less useful as processors enforce stricter alignment.
+   And it hadn't been tested in ages, and was thus probably broken anyway.
+
+Since 6.0alpha6:
+ - Added GC_finalizer_notifier.  Fixed GC_finalize_on_demand.  (The variable
+   actually wasn't being tested at the right points.  The build-time flag
+   was.)
+ - Added Tom Tromey's S390 Linux patch.
+ - Added code to push GC_finalize_now in GC_push_finalizer_structures.
+   (Thanks to Matthew Flatt.)
+ - Added GC_push_gc_structures() to push all GC internal roots.
+ - Integrated some FreeBSD changes from Matthew Flatt.
+ - It looks like USRSTACK is not always correctly defined under Solaris.
+   Hacked gcconfig.h to attempt to work around the problem.  The result
+   is not well tested.  (Thanks again to Matthew Flatt for pointing this
+   out.  The gross hack is mine. - HB)
+ - Added Ji-Yong Chung's win32 threads and C++ fixes.
+ - Arranged for hpux_test_and_clear.s to no longer be needed or built.
+   It was causing build problems with gas, and it's not clear this is
+   better than the pthreads alternative on this platform.
+ - Some MINGW32 fixes from Hubert Garavel.
+ - Added Initial Hitachi SH4 port from Kaz Kojima.
+ - Ported thread-local allocation and parallel mark code to HP/UX on PA_RISC.
+ - Made include/gc_mark.h more public and separated out the really private
+   pieces.  This is probably still not quite sufficient for clients that
+   want to supply their own kind of type information.  But it's a start.
+   This involved lots of identifier renaming to make it namespace clean.
+ - Added GC_dont_precollect for clients that need complete control over
+   the root set.
+ - GC_is_visible didn't do the right thing with gcj objects.  (Not that
+   many people are likely to care, but ...)
+ - Don't redefine read with GC_USE_LD_WRAP.
+ - Initial port to LINUX/HP_PA.  Incremental collection and threads are not
+   yet supported.  (Incremental collection should work if you have the
+   right kernel.  Threads may work with a sufficiently patched pthread
+   library.)
+ - Changed gcconfig.h to recognize __i386__ as an alternative to i386 in
+   many places.  (Thanks to Benjamin Lerman.)
+ - Made win32_threads.c more tolerant of detaching a thread that it didn't
+   know about.  (Thanks to Paul Nash.)
+ - Added Makefile.am and configure.in from gcc to the distribution, with
+   minimal changes.  For the moment, those are just placeholders.  In the
+   future, we're planning to switch to a GNU-style build environment for
+   Un*x-like systems, though the old Makefile will remain as a backup.
+ - Turned off STUBBORN_ALLOC by default, and added it back as a Makefile
+   option.
+ - Redistributed some functions between malloc.c and mallocx.c, so that
+   simple statically linked apps no longer pull in mallocx.o.
+ - Changed large object allocation to clear the first and last few words
+   of each block before releassing the lock.  Otherwise the marker could see
+   objects with nonsensical type descriptors.
+ - Fixed a couple of subtle problems that could result in not recognizing
+   interior pointers from the stack.  (I believe these were introduced
+   in 6.0alpha6.)
+ - GC_debug_free_inner called GC_free, which tried to reacquire the
+   allocator lock, and hence deadlocked.  (DBG_HDRS_ALL probably never worked
+   with threads?)
+ - Fixed several problems with back traces.  Accidental references to a free
+   list could cause the free list pointer to be overwritten by a back pointer.
+   There seemed to be some problems with the encoding of root and finalizer
+   references.
+  
+Since 6.0alpha7:
+ - Changed GC_debug_malloc_replacement and GC_debug_realloc_replacement
+   so that they compile under Irix.  (Thanks to Dave Love.)
+ - Updated powerpc_macosx_mach_dep.s so that it works if the collector
+   is in a dynamic library.  (Thanks to Andrew Begel.)
+ - Transformed README.debugging into debugging.html, updating and
+   expanding it in the process.  Added gcdescr.html and tree.html
+   from the web site to the GC distribution.
+ - Fixed several problems related to PRINT_BLACK_LIST. This involved
+   restructuring some of the marker macros.
+ - Fixed some problems with the sizing of objects with debug information.
+   Finalization was broken KEEP_BACK_PTRS or PRINT_BLACK_LIST.  Reduced the
+   object size with SHORT_DEBUG_HDRS by another word.
+ - The "Needed to allocate blacklisted ..." warning had inadvertently
+   been turned off by default, due to a buggy test in allchblk.c.  Turned
+   it back on.
+ - Removed the marker macros to deal with 2 pointers in interleaved fashion.
+   They were messy and the performance improvement seemed minimal.  We'll
+   leave such scheduling issues to the compiler.
+ - Changed Linux/PowerPC test to also check for __powerpc__ in response
+   to a discussion on the gcc mailing list.
+ - On Matthew Flatt's suggestion removed the "static" from the jmp_buf
+   declaration in GC_generic_push_regs.  This was causing problems in
+   systems that register all of their own roots.  It looks far more correct
+   to me without the "static" anyway. 
+ - Fixed several problems with thread local allocation of pointerfree or
+   typed objects.  The collector was reclaiming thread-local free lists, since
+   it wasn't following the link fields.
+ - There was apparently a long-standing race condition related to multithreaded
+   incremental collection.  A collection could be started and a thread stopped
+   between the memory unprotect system call and the setting of the
+   corresponding dirt bit.  I believe this did not affect Solaris or PCR, which
+   use a different dirty-bit implementation.  Fixed this by installing
+   signal handlers with sigaction instead of signal, and disabling the thread
+   suspend signal while in the write-protect handler.  (It is unclear
+   whether this scenario ever actually occurred.  I found it while tracking
+   down the following:)
+ - Incremental collection did not cooperate correctly with the PARALLEL_MARK
+   implementation of GC_malloc_many or the local_malloc primitves.  It still
+   doesn't work well, but it shouldn't lose memory anymore.
+ - Integrated some changes from the gcc source tree that I had previously
+   missed.  (Thanks to Bryce McKinley for the reminder/diff.)
+ - Added Makefile.direct as a copy of the default Makefile, which would
+   normally be overwritten if configure is run.
+ - Changed the gc.tar target in Makefile.direct to embed the version number
+   in the gc directory name.  This will affect future tar file distributions.
+ - Changed the Irix dynamic library finding code to no longer try to
+   eliminate writable text segments under Irix6.x, since that is probably no
+   longer necessary, and can apparently be unsafe on occasion.  (Thanks to
+   Shiro Kawai for pointing this out.)
+ - GC_cleanup with GC_DEBUG enabled passed a real object base address to
+   GC_debug_register_finalizer_ignore_self, which expected a pointer past the
+   debug header.  Call GC_register_finalizer_ignore_self instead, even with
+   debugging enabled.  (Thanks to Jean-Daniel Fekete for catching this.)
+ - The collector didn't build with call chain saving enabled but NARGS=0.
+   (Thanks to Maarten Thibaut.)
+ - Fixed up the GNU-style build files enough so that they work in some
+   obvious cases.
+ - Added initial port to Digital Mars compiler for win32. (Thanks to Walter
+   Bright.)
+
+Since 6.0alpha8:
+ - added README.macros.
+ - Made gc.mak a symbolic link to work around winzip's tendency to ignore
+   hard links.
+ - Simplified the setting of NEED_FIND_LIMIT in os_dep.c, possibly breaking
+   it on untested platforms.
+ - Integrated initial GNU HURD port. (Thanks to Chris Lingard and Igor
+   Khavkine.)
+ - A few more fixes for Digital Mars compiler (Walter Bright).
+ - Fixed gcc version recognition.  Renamed OPERATOR_NEW_ARRAY to
+   GC_OPERATOR_NEW_ARRAY.  Changed GC_OPERATOR_NEW_ARRAY to be the default.
+   It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY.  (Thanks to
+   Cesar Eduardo Barros.) 
+ - Changed the byte size to free-list mapping in thread local allocation
+   so that size 0 allocations are handled correctly.
+ - Fixed Linux/MIPS stackbottom for new toolchain. (Thanks to Ryan Murray.)
+ - Changed finalization registration to invoke GC_oom_fn when it runs out
+   of memory.
+ - Removed lvalue cast in finalize.c.  This caused some debug configurations
+   not to build with some non-gcc compilers.
+
+Since 6.0alpha9:
+ - Two more bug fixes for KEEP_BACK_PTRS and DBG_HDRS_ALL.
+ - Fixed a stack clearing problem that resulted in SIGILL with a
+   misaligned stack pointer for multithreaded SPARC builds.
+ - Integrated another HURD patch (thanks to Igor Khavkine).
+
+Since 6.0:
+ - Non-debug, atomic allocations could result in bogus smashed object
+   reports with debugging on.  (Thanks to Patrick Doyle for the small
+   test case.)
+ - Fixed GC_get_register_stack_base (Itanium only) to work around a glibc
+   2.2.4 bug.
+ - Initial port to HP/UX on Itanium.  Thread support and both 32 and 64
+   bit ABIs appear to work.  Parallel mark support doesn't yet, due to
+   some inline assembly code issues.  Thread local allocation does appear
+   to work.
+ - ifdef'ed out glibc2.1/Itanium workaround.  I suspect nobody is using
+   that combination anymore.
+ - Added a patch to make new_gc_alloc.h usable with gcc3.0.  (Thanks to
+   Dimitris Vyzovitis for the patch.)
+ - Debugged 64-bit support on HP/UX PA-RISC.
+ - Turned on dynamic loading support for FreeBSD/ELF.  (Thanks to Peter
+   Housel.)
+ - Unregistering of finalizers with debugging allocation was broken.
+   (Thanks to Jani Kajala for the test case.)
+ - Old finalizers were not returned correctly from GC_debug_register_finalizer.
+ - Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work.
+ - Cleaned up some statistics gathering code in reclaim.c (Thanks to Walter
+   Bright.)
+ - Added some support for OpenBSD/ELF/Linux.  (Thanks to Suzuki Toshiya.)
+ - Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library
+   traversal to dyn_load.c.  Changed it to weakly reference dl_iterate_phdr,
+   so that the old code is stilll used with old versions of glibc.
+ - Cleaned up feature test macros for various threads packages and
+   integrated (partially functional) FreeBSD threads code from Loren Rittle.
+   It's likely that the cleanup broke something, since it touched lots of
+   code.  It's also likelly that it fixed some unreported bugs in the
+   less common thread implementations, since some of the original code
+   didn't stand up to close scrutiny.  Support for the next pthreads
+   implementation should be easier to add.
+
+Since 6.1alpha1:
+ - No longer wrap read by default in multithreaded applications.  It was
+   pointed out on the libgcj list that this holds the allocation lock for
+   way too long if the read blocks.  For now, reads into the heap are
+   broken with incremental collection.  It's possible to turn this back on
+   if you make sure that read calls don't block (e.g. by calling select
+   first).
+ - Fix ifdef in Solaris_threads.h to refer to GC_SOLARIS_THREADS.
+ - Added check for environment variable GC_IGNORE_GCJ_INFO.
+ - Added printing of stop-the-world GC times if GC_PRINT_STATS environment
+   variable is set.
+ - The calloc definition in leak_detector.h was missing parentheses, and
+   realloc was missing a second argument to GC_REALLOC.
+   (Thanks to Elrond (elrond<at>samba-tng.org).)
+ - Added GC_PRINT_BACK_HEIGHT environment variable and associated
+   code, mostly in the new file backgraph.c.  See doc/README.environment.
+ - Added -DUSE_GLOBAL_ALLOC to work around a Windows NT issue.  (Thanks to
+   Jonathan Clark.)
+ - Integrated port to NEC EWS4800 (MIPS-based workstation, with somewhat
+   different address-space layout). This may help for other machines with
+   holes in the data segment.  (Thanks to Hironori Sakamoto.)
+ - Changed the order in which GC_push_roots and friends push things onto
+   the mark stack.  GC_push_all calls need to come first, since we can't
+   necessarily recovere if those overflow the mark stack.  (Thanks to
+   Matthew Flatt for tracking down the problem.)
+ - Some minor cleanups to mostly support the Intel compiler on Linux/IA64.
+
+Since 6.1 alpha2:
+ - Minor cleanup on the gcconfig.h section for SPARC.
+ - Minor fix to support Intel compiler for I386/Linux. (Thanks to Sven
+   Hartrumpf.)
+ - Added SPARC V9 (64-bit) support.  (Thanks to Jeff Sturm.)
+ - Restructured the way in which we determine whether or not to keep
+   call stacks for debug allocation.  By default SAVE_CALL_COUNT is
+   now zero on all platforms.  Added SAVE_CALL_NARGS parameters.
+   If possible, use execinfo.h to capture call stack.  (This should
+   add support for a number of new platforms, though often at
+   considerable runtime expense.)
+ - Try to print symbolic information for call stacks.  On Linux, we
+   do this with a combination of execinfo.h and running addr2line in
+   a separate process.  This is both much more expensive and much more
+   useful.  Amazingly, it seems to be fast enough for most purposes.
+ - Redefined strdup if -DREDIRECT_MALLOC is given.
+ - Changed incremental collector and MPROTECT_VDB implementation so that,
+   under favorable conditions, pointerfree objects are not protected.
+   Added GC_incremental_protection_needs() to determine ahead of time whether
+   pointerfree objects may be protected.  Replaced GC_write_hint() with
+   GC_remove_protection().
+ - Added test for GC_ENABLE_INCREMENTAL environment variable.
+ - Made GC_time_limit runtime configurable.  Added GC_PAUSE_TIME_TARGET
+   environment variable.
+ - Eliminated GC_page_sz, a duplicate of GC_page_size.
+ - Caused the Solaris and Irix thread creation primitives to call
+   GC_init_inner().
+Since 6.1alpha3:
+ - Fixed typo in sparc_mach_dep.S, preventing the 64-bit version from
+   building.  Increased 64-bit heap size limit in test.c slightly, since
+   a functional SPARC collector seems to slightly exceed the old limits.
+   (Thanks again to Jeff Sturm.)
+ - Use NPRGREG in solaris_threads.c, thus printing all registers if things
+   go wrong.
+ - Added GC_MARKERS environment variable to allow use of a single marker
+   thread on an MP without confusing the lock implementation.
+ - Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED.
+   This is really a purely generational mode, and we can afford to 
+   postpone the collection until the heap is (nearly) full.
+ - Remove read() wrapper for MPROTECT_VDB.  It was causing more harm than
+   good.  It is often no longer needed if system calls avoid writing to
+   pointerfull heap objects.
+ - Fix MACOSX test in gcconfig.h. (Thanks to John Clements.)
+ - Change GC_test_and_set so that it consistently has one argument.
+   Add spaces to ::: in powerpc assembly code in gc_locks.h.
+   (Thanks to Ryan Murray.)
+ - Fixed a formatting error in dbg_mlc.c.  Added prototype to GC_abort()
+   declaration.   (Thanks to Michael Smith.)
+ - Removed "source" argument to GC_find_start().  Eliminate GC_FIND_START().
+ - Added win32 recognition code in configure.in.  Changed some of the
+   dllimport/export defines in gc.h.  (Thanks to Adam Megacz.)
+ - GC_malloc_many didn't set hb_last_reclaimed when it called 
+   GC_reclaim_generic.  (I'm not sure this matters much, but ...)
+ - Allocating uncollectable objects with debug information sometimes
+   allocated objects that were one byte too small, since uncollectable
+   objects don't have the extra byte added at the end.  (Thanks to
+   Wink Saville for pointing this out.)
+ - Added a bit more assertion checking to make sure that gcj objects
+   on free lists never have a nonzero second word.
+ - Replaced BCC_MAKEFILE with an up-to-date one.  (Thanks to 
+   Andre Leiradella.)
+ - Upgraded libtool, cinfigure.in and some related files to hopefully
+   support NetBSD/SPARC.  (Thanks to Adrian Bunk.)  Unfortunately,
+   libtool 1.4.2 seemed to be buggy due to missing quotes in several
+   "test" invocations.  Fixed those in the ltmain.sh script.
+ - Some win32-specific patches, including the introduction of
+   GC_CreateThread.  (Thanks to Adam Megacz.)
+ - Merged in gcj changes from Anthony Green to support embedded systems.
+ - Tried to consistently rename preprocessed assembly files with a capital
+   .S extension.
+ - Use alpha_mach_dep.S on ALPHA again.  It doesn't really matter, but this
+   makes our distribution consistent with the gcc one, avoiding future merge
+   problems.
+ - Move GET_MEM definition into gcconfig.h.  Include gcconfig.h slightly
+   later in gc_priv.h to avoid forward references to ptr_t.
+ - Add some testing of local allocation to test.c.
+ - Change definition of INVALID_QTID in specific.h.  The -1 value was used
+   inconsistently, and too likely to collide with a valid stack address.
+   Some general clean-up of specific.[ch].  Added assertions.  (Thanks
+   to Michael Smith for tracking down an intermittent bug to this
+   general area.  I'm not sure it has been squashed yet, however.)
+ - On Pthread systems it was not safe to call GC_malloc() between fork()
+   and exec().  According to the applicable standards, it doesn't appear
+   to be safe to call malloc() or many other libc functions either, thus
+   it's not clear this is fixable.  Added experimental support for
+   -DHANDLE_FORK in linux_threads.c which tries to support it.  It may
+   succeed if libc does the right thing.  I'm not sure whether it does.
+   (Thanks to Kenneth Schalk for pointing out this issue.)
+ - Documented thread local allocation primitives to require an
+   explicit GC_init call.  GC_init_parallel is no longer declared to
+   be a constructor function, since that isn't portable and often
+   seems to lead to initialization order problems.
+ - Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them
+   compatible with Visual C++ 6.  (Thanks to Wink Saville for the
+   patch.)
+ - Some more patches for Linux on HP PA-RISC.
+ - Added include/gc_allocator.h.  It implements (hopefully) standard
+   conforming (as opposed to SGI-style) allocators that allocate
+   collectable (gc_allocator) or GC-traceable, but not collectable
+   (traceable_allocator) objects.  This borrows heavily from libstc++,
+   which borrows heavily from the SGI implementation, this part of
+   which was written by Matt Austern.  Changed test_cpp.cc to very
+   minimally test this.
+ - On Linux/X86, retry mmap with a different start argument.  That should
+   allow the collector to use more (closer to 3GB) of the address space.
+   (Thanks to Jeffrey Mark Siskind for tracking this down.)
+ - Force 64 bit alignment with GCJ support.  (Reflects Bryce McKinley's
+   patch to the gcc tree.)
+ - Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init
+   to accomodate some glibc5 systems.  (Thanks to Dan Fandrich for the
+   patch.)
+ - Compensated for the fact that current versions of glibc set
+   __libc_stack_end incorrectly on Linux/IA64 while initialization code
+   is running.  This could cause the collector to miss 16 bytes of
+   the memory stack if GC_malloc or friends where called before main().
+ - Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86.
+   This will probably take another iteration to work, since his
+   patch conflicted with the libtool upgrade. 
+ - Added README.arm.cross containing some information about cross-
+   compiling to an ARM processor from Margaret Fleck.
+
+Since 6.1alpha4:
+ - Added GC_finalizer_mem_freed, and changed some of the code that
+   decided on heap expansion to look at it.  Memory explicitly
+   deallocated by finalizers essentially needs to be counted as reclaimed
+   by the GC.  Otherwise there are cases in which the heap can grow
+   unboundedly.  (Thanks to Mark Reichert for the test case.)
+ - Integrated Adam Megacz patches to not scan dynamic libraries if
+   we are compiling with gcc on win32.  Otherwise we need structured
+   exception handling to deal with asynchronously unmapped root
+   segments, and gcc doesn't directly support that.
+ - Integrated Anthony Green's patch to support Wine.
+ - GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
+   places, including gc_cpp.cc.  (Thanks to Wink Saville for pointing
+   this out.)
+ - Integrated Loren James Rittle's Alpha FreeBSD patches.  In
+   response to Richard Henderson's suggestion, these also
+   changed the declarations of symbols like _end on many platforms to
+   that they wouldn't mistakenly be declared as short data symbols.
+ - Integrated changes from the Debian distribution.  (Thanks to Ryan Murray
+   for pointing these out.)  Fix C++ comments in POWERPC port.  Add ARM32
+   incremental GC support.  Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
+   this time for real.  Use va_copy to get rid of cord printf problems
+   (finally).
+ - Close file descriptor used to count cpus.  Thanks to Jeff Sturm for
+   pointing out the omission.
+ - Don't just drop gcj free lists in GC_start_reclaim, since that can
+   eventually cause the marker to see a bogus mark descriptor in the 
+   dropped objects.  The usual symptom was a very intermittent segmentation
+   fault in the marker.  This mattered only if one of the GC_gcj_malloc
+   variants was used.  (Thanks to Michael Smith, Jeff Sturm, Bryce
+   McKinley and Tom Tromey for helping to track this down.)
+ - Fixed Linux and Solaris/64 SPARC configuration.  (Thanks to David Miller,
+   Jeff Sturm, Tom Tromey, and Christian Joensson.)
+ - Fixed a typo in strdup definition.  (Thanks to Gerard A Allan.)
+ - Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
+   This is needed on Linux.  I'm not sure whether it's better or worse
+   on Tru64.
+ - Changed gc_cpp.h once more to declare operator new and friends only in
+   a Microsoft environment.  This may need further fine tuning.  (Thanks to
+   Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4.)
+ - Don't ever override strdup if it's already macro defined.  (Thanks to
+   Adnan Ali for pointing out the problem.)
+ - Changed gc_cpp.h yet again to also overload placement new.  Due to the
+   C++ overloading rules, the other overloaded new operations otherwise hide
+   placement new, which causes many STL uses to break.  (Thanks to Reza
+   Shahidi for reporting this, and to Matt Austern for proposing a fix.)
+ - Integrated cygwin pthreads support from Dan Bonachea.
+ - Turn on DYNAMIC_LOADING for NetBSD.  (Thanks to Krister Walfridsson.)
+ - Changed printing code to print more complete GC times.
+ - Applied Mark Mitchell's Irix patch to correct some bitrot.
+ - Clarified which object-printing routines in dbg_mlc.c should hold
+   the allocation lock.  Restructured the code to allow reasonable object
+   printing with -DREDIRECT_MALLOC.
+ - Fix the Linux mmap code to always start with 0x1000 as the initial hint.
+   Minor patches for 64-bit AIX, particularly to STACKBOTTOM.
+   (Thanks again to Jeffrey Mark Siskind.)
+ - Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
+   with a system header. (Thanks to Philp Brown.)
+ - Cause win32_threads.c to handle an out of range stack pointer correctly,
+   though currently with a warning.  (Thanks to Jonathan Clark for
+   observing that win32 applications may temporarily use the stack
+   pointer for other purposes, and suggesting a fix.  Unfortunately, it's
+   not clear that there is a complete solution to this problem.)
+
+Since 6.1alpha5:
+ - Added GC_MAXIMUM_HEAP_SIZE environment variable.
+ - Fix configure.in for MIPS/LINUX. (Thanks to H.J. Lu.)
+ - Double page hash table size for -DLARGE_CONFIG.
+ - Integrated Bo Thorsen's X86-64 support.
+ - STACKBOTTOM definition for LINUX/MIPS was partially changed back.
+   (Thanks to H.J. Lu and Hiroshi Kawashima for resolving this.)
+ - Replaced all occurrences of LINUX_DATA_START in gcconfig.h with
+   SEARCH_FOR_DATA_START.  It doesn't hurt to falll back to a search.
+   And __data_start doesn't seem to get defined correctly of the GC
+   library is loaded with LD_PRELOAD, e.g. for leak detection.
+ - If the GC_find_leak environment variable is set, do a
+   atexit(GC_gcollect) to give us at least one chance to detect leaks.
+   This may report some very benign leaks, but ...
+ - Addeded REDIRECT_FREE.  It's necessary if we want leak detection with
+   LD_PRELOAD.
+ - Defer printing of leaked objects, as for smashed objects.
+ - Fixed process and descriptor leak in GC_print_callers.  Try for
+   line number even if we got function name.)
+ - Ported parallel GC support and thread local allocation to Alpha.
+   Not yet well-tested.
+ - Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump().
+ - Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct
+   alpha_mach_dep.s.  (Thanks to Fergus Henderson.)
+ - Incorporated a change to new_gc_alloc.h, suggested by Johannes Schmidt,
+   which should make it work with gcc3.1.  (I would still like to encourage
+   use of gc_allocator.h instead.) 
+ - Use alpha_mach_dep.S only on Linux.  (It's not clear that this is
+   optimal, but it otherwise didn't build on Tru64.  Thanks to Fergus
+   Henderson.)
+ - Added ifdef to guard free() in os_dep.c.  Otherwise we get a
+   compilation error on Irix.  (Thanks to Dai Sato.)
+ - Added an experimental version of GC_memalign to mallocx.c.  This can't
+   always work, since we don't handle alignment requests in the hblk-level
+   allocator, and we can't handle arbitrary pointer displacements unless
+   GC_all_interior_pointers is enabled.  But it should work for alignment
+   requests up to HBLKSIZE.  This is not yet documented in the standard
+   places.
+ - Finally debugged the OSF1/Tru64 thread support.  This needs more testing,
+   since I needed to add a somewhat unconvincing workaround for signal
+   delivery issues that I don't yet completely understand.  But it does
+   pass my tests, even in parallel GC mode.  Incremental GC support is
+   disabled if thread support is enabled, due to the signal issues.
+ - Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h.
+ - Added GC_debug_malloc_replacement and GC_debug_realloc_replacement
+   declarations to gc.h.  On IA64, this is required for REDIRECT_MALLOC
+   to work correctly with these.
+ - Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
+
+Since 6.1:
+ - Guard the test for GC_DUMP_REGULARLY in misc.c with
+   "#ifndef NO_DEBUGGING".  Otherwise it fails to build with NO_DEBUGGING
+   defined.  (Thanks to Manuel Serrano.)
+ - Message about retrying suspend signals was incorrectly generated even when
+   flag was not set.
+ - Cleaned up MACOSX/NEXT root registration code.  There was apparently a
+   separate ifdef case in GC_register_data_segments() for no reason.
+ - Removed MPROTECT_VDB for MACOSX port, based on one negative report.
+ - Arrange for gc.h and friends to be correctly installed with GNU-style
+   "make install".
+ - Enable the GNU-style build facility include C++ support in the library
+   with --enable-cplusplus. (Thanks to Thomas Maier for some of the patch.)
+ - Mark from GC_thread_key in linux_threads.c, in case that's allocated
+   from the garbage collected heap, as it is with our own thread-specific
+   storage implementation.  (Thanks to Jeff Sturm.)
+ - Mark all free list header blocks if they are heap allocated.  This avoids
+   some unnecessary tracing.  And it remains correct if we clear the
+   root set. (Thanks to Jeff Sturm for identifying the bug.)
+ - Improved S390/Linux support.  Add S390/Linux 64-bit support.  (Thanks
+   to Ulrich Weigand.)
+ - Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to
+   GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h.  This is technically
+   an interface change.  Based on the fact that nobody reported this,
+   I suspect/hope there were no clients.
+ - Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration
+   when appropriate, (2) doesn't generate references to undefined internal
+   macros, and (3) allows easier manual construction of descriptors.
+ - Close the file descriptor used by GC_print_address_map().
+ - Set the "close-on-exec" bit for various file descriptors maintained
+   for the collector's internal use.
+ - Added a hack to find memory segments owned by the system allocator
+   under win32.  Based on my tests, this tends to eventually find all
+   segments, though it may take a while.  There appear to be cleaner,
+   but slower solutions under NT/XP.  But they rely on an API that's
+   unsupported under 9X.
+ - Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM.  (Thanks
+   to Akira Tagoh for pointing out that HEURISTIC1 doesn't work on
+   64-bit kernels.)
+ - Added GC_set_free_space_divisor to avoid some Windows dll issues.
+ - Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing
+   of candidate pointers for tagging, etc.
+ - Always lock around GC_notify_full_gc().  Simplified code for
+   invoking GC_notify_full_gc().
+ - Changed the way DATASTART is defined on FreeBSD to be robust against
+   an unmapped page after etext.  (Thanks to Hironori Sakamoto for
+   tracking down the intermittent failure.)
+ - Made GC_enable() and GC_disable() official.  Deprecated direct update
+   of GC_dont_gc.  Changed GC_gcollect to be a noop when garbage collection
+   is disabled.
+ - Call GC_register_dynamic_libraries before stopping the world on Linux,
+   in order to avoid a potential deadlock due to the dl_iterate_phdr lock.
+ - Introduced a more general mechanism for platform-dependent code to
+   decide whether the main data segment should be handled separately
+   from dynamic libraries, or registered by GC_register_dynamic_libraries.
+   The latter is more reliable and easier on Linux with dl_iterate_phdr. 
+
+Since 6.2alpha1:
+ - Fixed the completely broken FreeBSD code in 6.2alpha1.  (Thanks to
+   Hironori Sakamoto for the patch.)
+ - Changed IRIX reference in dbg_mlc.c to IRIX5. (Thanks to Marcus Herbert.)
+ - Attempted to work around the problems with .S filenames and the SGI
+   compiler.  (Reported by several people. Untested.)
+ - Worked around an HP/UX make issue with the GNU-style build process.
+ - Fixed the --enable-cplusplus build machinery to allow builds without
+   a C++ compiler.  (That was always the intent ...)
+ - Changed the debugging allocation macros to explicitly pass the return
+   address for Linux and XXXBSD on hardware for which we can't get stack
+   traces.  Use __builtin_return_address(0) to generate it when possible.
+   Some of the configuration work was cleaned up (good) and moved to gc.h
+   (bad, but necessary).  This should make leak detection more useful
+   on a number of platforms.  (Thanks to Fabian Thylman for the suggestion.)
+ - Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER.
+ - Bumped revision number for dynamic library.
+
+Since 6.2alpha2:
+ - Don't include execinfo.h in os_dep.c when it's not needed, and may not exist.
+
+Since 6.2alpha3:
+ - Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS.  (See Debian bug
+   # 177204)
+ - Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches.
+ - Integrated Grzegorz Jakacki's substantial GNU build patch.  "Make dist"
+   should now work for the GNU build process.  Documentation files
+   are installed under share/gc.
+ - Tweaked gc_cpp.h to again support the Borland compiler.  (Thanks to
+   Rene Girard for pointing out the problems.)
+ - Updated BCC_MAKEFILE (thanks to Rene Girard).
+ - Added GC_ASSERT check for minimum thread stack size.
+ - Added --enable-gc-assertions.
+ - Added some web documentation to the distribution.  Updated it in the
+   process.
+ - Separate gc_conf_macros.h from gc.h.
+ - Added generic GC_THREADS client-defined macro to set the appropriate
+   GC_XXX_THREADS internal macro.  (gc_config_macros.h.)
+ - Add debugging versions of _ignore_off_page allocation primitves.
+ - Moved declarations of GC_make_closure and GC_debug_invoke_finalizer
+   from gc.h to gc_priv.h.
+ - Reset GC_fail_count even if only a small allocation succeeds.
+ - Integrated Brian Alliet's patch for dynamic library support on Darwin.
+ - gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF
+   when it should have called the lower case version, since it was
+   explicitly computing a base pointer.
+
+Since 6.2alpha4:
+ - GC_invoke_finalizers could, under rare conditions, set
+   GC_finalizer_mem_freed to an essentially random value.  This could
+   possibly cause unbounded heap growth for long-running applications
+   under some conditions.  (The bug was introduced in 6.1alpha5, and
+   is not in gcc3.3.  Thanks to Ben Hutchings for finding it.)
+ - Attempted to sanitize the various DLL macros.  GC_USE_DLL disappeared.
+   GC_DLL is used instead.  All internal tests are now on GC_DLL.
+   README.macros is now more precise about the intended meaning.
+ - Include DllMain in the multithreaded win32 version only if the
+   collector is actually built as a dll.  (Thanks to Mohan Embar for
+   a version of the patch.)
+ - Hide the cygwin threadAttach/Detach functions.  They were violating our
+   namespace rules.  
+ - Fixed an assertion in GC_check_heap_proc.  Added GC_STATIC_ASSERT.
+   (Thanks again to Ben Hutchings.)
+ - Removed some obsolete definitions for Linux/PowerPC in gcconfig.h.
+ - CORD_cat was not rebalancing unbalanced trees in some cases, violating
+   a CORD invariant.  Also tweaked the rebalancing rule for
+   CORD_cat_char_star.  (Thanks to Alexandr Petrosian for the bug report
+   and patch.)
+ - Added hand-coded structured exception handling support to mark.c.
+   This should enable support of dynamic libraries under win32 with
+   gcc-compiled code.  (Thanks to Ranjit Mathew for the patch.)
+   Turned on dynamic library scanning for win32/gcc.
+ - Removed some remnants of read wrapping.  (Thanks to Kenneth Schalk.)
+   GC_USE_LD_WRAP ws probably broken in recent versions.
+ - The build could fail on some platforms since gcconfig.h could include
+   declarations mentioning ptr_t, which was not defined, e.g. when if_mach
+   was built.  (Thanks to Yann Dirson for pointing this out.)  Also
+   cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit. 
+ - The GC_LOOP_ON_ABORT environment variable interfered with incremental
+   collection, since the write fault handler was erroneously overridden.
+   Handlers are now set up in the correct order.
+ - It used to be possible to call GC_mark_thread_local_free_lists() while
+   the world was not stopped during an incremental GC.  This was not safe.
+   Fortunately, it was also unnecessary.  Added GC_world_stopped flag
+   to avoid it.  (This caused occasional crashes in GC_set_fl_marks
+   with thread local allocation and incremental GC.  This probably happened
+   primarily on old, slow multiprocessors.)
+ - Allowed overriding of MAX_THREADS in win32_threads.c from the build
+   command line.  (Patch from Yannis Bres.)
+ - Taught the IA64/linux code to determine the register backing store base from
+   /proc/self/maps after checking the __libc symbol, but before guessing.
+   (__libc symbols are on the endangered list, and the guess is likely to not
+   always be right for 2.6 kernels.)  Restructured the code to read and parse
+   /proc/self/maps so it only exists in one place (all platforms).
+ - The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux.  It claimed that it
+   also registered the main data segment, but didn't actually do so.  (I don't
+   think anyone actually uses this configuration, but ...)
+ - Made another attempt to get --enablecplusplus to do the right thing.
+   Since there are unavoidable problems with C programs linking against a
+   dynamic library that includes C++ code, I separated out the c++ code into
+   libgccpp.
+
+Since 6.2alpha5:
+ - There was an extra underscore in the name of GC_save_registers_in_stack
+   for NetBSD/SPARC.  (Thanks to Jaap Boender for the patch.)
+ - Integrated Brian Alliet's patch for Darwin.  This restructured the
+   linuxthreads/pthreads support to separate generic pthreads support
+   from more the system-dependent thread-stopping code.  I believe this
+   should make it easier to eliminate the code duplication between
+   pthreads platforms in the future.  The patch included some other
+   code cleanups.
+ - Integrated Dan Bonachea's patch to support AIX threads.  This required
+   substantial manual integration, mostly due to conflicts with other
+   recent threads changes.  It may take another iteration to
+   get it to work.
+ - Removed HPUX/PA-RISC support from aix_irix_threads.c.  It wasn't used
+   anyway and it cluttered up the code.  And anything we can do to migrate
+   towards generic pthreads support is a good thing.
+ - Added a more explicit test for tracing of function arguments to test.c.
+   (Thanks to Dan Grayson.)
+ - Added Akira Tagoh's PowerPC64 patch.
+ - Fixed some bit rot in the Cygwin port.  (Thanks to Dan Bonachea for
+   pointing it out.)  Gc.h now includes just windows.h, not winbase.h.
+ - Declared GC_save_regs_in_stack() in gc_priv.h.  Remove other declarations.
+ - Changed --enable-cplusplus to use automake consitionals.  The old way
+   confused libtool.  "Make install" didn't work correctly for the old version.
+   Previously --enable-cplusplus was broken on cygwin.
+ - Changed the C version of GC_push_regs to fail at compile time if it is
+   generated with an empty body.  This seems to have been the cause of one
+   or two subtle failures on unusual platforms.  Those failures should
+   now occur at build time and be easily fixable.
+
+Since 6.2alpha6:
+ - Integrated a second round of Irix/AIX patches from Dan Bonachea.
+   Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires
+   the Irix assembler to do the C preprocessing; gcc -E doesn't work.
+ - Fixed Makefile.direct for DARWIN.  (Thanks to Manuel Serrano.)
+ - There was a race between GC_pthread_detach and thread exit that could
+   result in a thread structure being deallocated by GC_pthread_detach
+   eventhough it was still needed by the thread exit code.  (Thanks to
+   Dick Porter for the small test case that allowed this to be debugged.)
+ - Fixed version parsing for non-alpha versions in acinclude.m4 and
+   version checking in version.h.
+
+Since 6.2:
+ - Integrated some NetBSD patches forwarded to me by Marc Recht.  These
+   were already in the NetBSD package.    
+ - GC_pthread_create waited for the semaphore even if pthread_create failed.
+   Thanks to Dick Porter for the pthread_support.c patch.  Applied the
+   analogous fix for aix_irix_threads.c.
+ - Added Rainer Orth's Tru64 fixes.
+ - The check for exceeding the thread table size in win32 threadDetach
+   was incorrect.  (Thanks to Alexandr Petrosian for the patch.)
+ - Applied Andrew Begel's patch to correct some reentrancy issues
+   with dynamic loading on Darwin.
+ - GC_CreateThread() was neglecting to duplicate the thread handle in
+   the table.  (Thanks to Tum Nguyen for the patch.)
+ - Pass +ESdbgasm only on PA-RISC machines with vendor compiler.
+   (Thanks to Roger Sayle for the patch.)
+ - Applied more AIX threads patches from Scott Ananian.
+
+Since 6.3alpha1:
+ - Reenabled I_HOLD_LOCK assertion in aix_irix_threads.h.
+ - Put back the WINABI qualifier for GC_CreateThread.  (Thanks to
+   Danny Smith for the patch.  6.3alpha1 had the qualifier in one place
+   but not elsewhere, which was clearly wrong.)
+ - Sometimes explicitly define __private_extern__ before DARWIN dyld.h
+   include.  (Thanks to Andreas Tobker for postting the patch.)
+ - Included signal.h from pthread_support.c.  Removed GC_looping_handler,
+   which was dead code.
+ - GC_find_start was misdeclared by gc_pmark.h if PRINT_BLACK_LIST was
+   defined.  (Thanks to Glauco Masotti for testing and reporting this.)
+   Changed GC_find_start to never just return 0.  According to its
+   comment it doesn't, and it's unclear that's correct.
+ - GC_alloc_large had several largely compensating bugs in the
+   computation of GC_words_wasted.  (It was confused about bytes vs.
+   words in two places.)
+ - Integrated Slava Sysoltev's patch to support more recent versions of
+   the Intel compiler on IA64/Linux.
+ - Changed win32 spinlock initialization to conditionally set a spin count.
+   (Emmanual Stumpf pointed out that enabling this makes a large performance
+   difference on win32 multiprocessors.)  Also cleaned up the win32 spinlock
+   initialization code a bit.
+ - Fixed thread support for HP/UX/IA64.  The register backing store base for
+   the main thread was sometimes not set correctly.  (Thanks to Laurent
+   Morichetti.)
+ - Added -DEMPTY_GETENV_RESULTS flag to work around Wine problem.
+ - Declare GC_stack_alloc and GC_stack_free in solaris_threads.h to
+   avoid 64-bit size mismatches.  (Thanks to Bernie Solomon.)
+ - Fixed GC_generic_push_regs to avoid a potential and very unfortunate
+   tail call optimization.  This could lead to prematurely reclaimed
+   objects on configurations that used the generic routine and the new
+   build infrastructure (which potentially optimizes mach_dep.c).
+   This was a serious bug, but it's unclear whether it has resulted in
+   any real failures.
+ - Fixed CORD_str to deal with signed characters.  (Thanks to Alexandr
+   Petrosian for noticing the problem and supplying the patch.)
+ - Merged a couple of NOSYS/ECOS tests into os_dep.c from gcj.  (Thanks
+   to Anthony Green.)
+ - Partially merged a win32 patch from Ben Hutchings, and substantially
+   revised other parts of win32_threads.c.  It had several problems.
+   Under MinGW with a statically linked library, the main thread was
+   not registered.  Cygwin detached threads leaked thread descriptors.
+   There were several race conditions.  For now, unfortunately the
+   static threads limit remains, though we increased it, and made table
+   traversal cost depend on the actual thread count.
+   There is also still some code duplication with pthread_support.c.
+   (Thread descriptors did become much smaller, since Ben Hutchings
+   removed the thread context from them.)
+ - Integrated a Solaris configure.in patch from Rainer Orth.
+ - Added GC_IGNORE_FB and associated warning to very partially address
+   the issue of the collector treating a mapped frame buffer as part
+   of the root set.  (Thanks to David Peroutka for providing some
+   insight.  More would be helpful.  Is there anything that can be used
+   to at least partially identify such memory segments?)
+   
+Since 6.3alpha2:
+ - Removed -DSMALL_CONFIG from BCC_MAKEFILE.
+ - Changed macros to test for an ARM processor (Patch from Richard Earnshaw.)
+ - Mostly applied a DJGPP patch from Doug Kaufman.  Especially Makefile.dj
+   had suffered from serious bit rot.
+ - Rewrote GC_apply_to_maps, eliminating an off-by-one subscript error,
+   and a call to alloca (for lcc compatibility).
+ - Changed USE_MUNMAP behavior on posixy platforms to immediately remap
+   the memory with PROT_NONE instead of unmapping it.  The latter risks
+   an intervening mmap grabbing the address space out from underneath us.
+   Updated this code to reflect a cleaner patch from Ulrich Drepper.
+ - Replaced _T with _Tp in new_gc_alloc.h to avoid a MACOS X conflict.
+   (Patch from Andrew Begel.)
+ - Dynamically choose whether or not lock should spin on win32.  (Thanks
+   to Maurizio Vairani for the patch.)  This may be a significant performance
+   improvement for win32.
+ - Fix Makefile.direct to actually include NT_STATIC_THREADS_MAKEFILE
+   in the distribution.  (Again thanks to Maurizio Vairani.)
+ - Maybe_install_looping_handler() was accidentally exported, violating
+   our name space convention.
+ - Made os_dep.c use sigsetjmp and SA_NODEFER for NetBSD.  (Thanks to
+   Christian Limpach.)  (I generalized the patch to use sigsetjmp on all
+   UNIX_LIKE platforms, admittedly a slightly risky move.  But it may avoid
+   similar problems on some other platforms. I also cleaned up the defn
+   of UNIX_LIKE a bit. - Hans)
+ - Integrated Andrew Begel's Darwin threads patch, adjusted according to
+   some of Fergus Hendersons's comments.  (Patch didn't apply cleanly,
+   errors are possible.)
+ - Added another test or two for the Intel 8.0 compiler to avoid
+   confusing it with gcc.  The single-threaded collector should now build
+   with icc, at least on ia64. 
+
+Since 6.3alpha3:
+ - USE_MMAP was broken by confusion in the code dealing with USE_MMAP_ANON.
+   (This was pointed out, and fixes were suggested by several other people.)
+ - Darwin supprt was broken in alpha3 as a result of my misintegration of
+   Andrew Begel's patches.  Fixed with another patch from Andrew Begel.
+ - A new sanity check in pthread_stop_world.c:GC_push_all_stacks() was
+   overly aggressive.  We may collect from an unregistered thread during
+   thread creation.  Fixed by explicitly checking for that case.  (Added
+   GC_in_thread_creation.)
+
+Since 6.3alpha4:
+ - Fix & vs && typo in GC_generic_malloc and
+   GC_generic_malloc_ignore_off_page.  (Propagated from the gcc tree.)
+ - Removed SA_NODEFER hack from NetBSD and Solaris write-protect handler.
+   (According to Christian Limpach, the NetBSD problem is fixed.
+   Presumably so is the Solaris 2.3 problem.)
+ - Removed placement delete from gc_cpp.h for the SGI compiler.
+   (Thanks to Simon Gornall for the patch.)
+ - Changed semantics of the GC_IGNORE_FB environment variable, based 
+   on experimentation by Nicolas Cannasse pointing out that the old
+   interpretation was useless.  We still need help in identifying win32
+   graphics memory mappings.  The current "solution" is a hack.
+ - Removed "MAKEOVERRIDES =" from Makefile.am and thus Makefile.in.
+   It probably made more sense in the gcc context.
+ - Explicitly ensure that NEED_FIND_LIMIT is defined for {Open,Net}BSD/ELF.
+ - Replaced USE_HPUX_TLS macro by USE_COMPILER_TLS, since gcc often
+   supports the same extension on various platforms.
+ - Added some basic (completely untested) defines for win64, in support
+   of future work.
+ - Declared GC_jmp_buf in os_dep.s as JMP_BUF instead of jmp_buf, fixing
+   a memory overwrite bug on Solaris and perhaps other platforms.
+ - Added 0 != __libc_stack_end test to GC_linux_stack_base.  (Thanks to Jakub
+   Jelinek, both for the patch, and for explaining the problem to me.)
+   Otherwise "prelink"ing could cause the collector to fail.
+ - Changed default thread local storage implementation to USE_PTHREAD_SPECIFIC
+   for HP/UX with gcc.  The compiler-based implementation appears to work
+   only with the vendor compiler.
+ - Export GC_debug_header_size and GC_USR_PTR_FROM_BASE from gc_mark.h,
+   making client mark code cleaner and less dependent on GC version.
+ - Export several new procedures and GC_generic_malloc from gc_mark.h
+   to support user-defined kinds.  Use the new procedures to replace existing
+   code in gcj_mlc.c and typd_mlc.c.
+ - Added support for GC_BACKTRACES.
+ - Fixed a remaining problem in CORD_str with signed characters.  (Thanks
+   to Alexandr Petrosian for the patch.)
+ - Removed supposedly redundant, but very buggy, definitions of finalizer
+   macros from javaxfc.h.  Fortunately this file probably has no users.
+   The correct declarations were already in gc.h.
+ - Also need to set GC_in_thread_creation while waiting for GC during
+   thread termination, since it is also possible to collect from an
+   unregistered thread in that case.
+ - Define NO_GETENV for Windows CE, since getenv doesn't appear to exist.
+   + some other minor WinCE fixes. (Thanks to Alain Novak.)
+ - Added GC_register_describe_type_fn.
+ - Arrange for debugging finalizer registration to ignore non-heap
+   registrations, since the regular version of the routine also behaves
+   that way.
+ - GC_gcj_malloc and friends need to check for finalizers waiting to be run.
+   One of the more obscure allocation routines with missing a LOCK() call.
+ - Fixed cvtres invocations in NT_MAKEFILE and NT_STATIC_THREADS_MAKEFILE
+   to work with VS.NET.
+ - Cleaned up GC_INIT calls in test.  Updated gc.man to encourage GC_INIT
+   use in portable code.
+ - Taught the GC to use libunwind if --enable-full-debug is specified on
+   IA64 and libunwind is present.
+ - The USE_MUNMAP code could get confused about the age of a block and
+   prematurely unmap it.  GC_unmap_old had a bug related to wrapping of
+   GC_gc_no.  GC_freehblk and GC_merge_unmapped didn't maintain
+   hb_last_reclaimed reasonably when blocks were merged.  The code was
+   fixed to reflect original intent, but that may not always be an
+   improvement.  See todo list item.
+
+Since 6.3alpha5:
+ - Define USE_GENERIC_PUSH_REGS for NetBSD/M68K.
+ - Fixed the X86_64 PREFETCH macros to correctly handle ia32e (which uses
+   different prefetch instructions from AMD64).  (Thanks to H.J. Lu.)
+ - GC_config_macros.h did not correctly define GC_WIN32_THREADS from
+   GC_THREADS. 
+ - Added simple_example.html.
+ - Merged Andrew Gray's patch to correctly restore signal handlers on
+   FreeBSD.
+ - Merged a patch from Andreas Jaeger to deal with prefetch-related warnings
+   on x86-64.  Added some other casts so that the PREFETCH macros
+   always get a ptr_t argument.  Removed some casts inthe PREFETCH
+   implementations.
+ - At Jesse Jones suggestion: Added a header guard for gc_allocator.h
+   and changed GC_debug_free to clobber contents of deallocated object.
+ - The signal masking code in pthread_stop_world.c contained some errors.
+   In particular SIGSEGV was masked in the handler, in spite of the fact that
+   it wrote to the heap.  This could lead to an uncaught SIGSEGV, which
+   apparently became much more likely in Linux 2.6.  Also fixed some
+   typos, and reduced code duplication in the same area.
+ - Remove ltconfig, clean up configure messages for DGUX (thanks to
+   Adrian Bunk for the patches).
+ - Integrated NetBSD/OpenBSD patches from Marc Recht and Matthias Drochner.
+
+Since 6.3alpha6:
+ - Compile test_cpp.cc with CXXCOMPILE instead of COMPILE.
+ - Very large allocations could cause a collector hang.  Correct
+   calculation of GC_collect_at_heapsize.
+ - GC_print_hblkfreelist printed some bogus results if USE_MUNMAP
+   was defined.
+ - Include gc_config_macros.h in threadlibs.c.
+ - Correct MacOSX thread stop code. (Thanks to Dick Porter.)
+ - SMALL_OBJ definition was off by one.  This could cause crashes
+   at startup.  (Thanks to Zoltan Varga for narrowing this down to
+   a trivial test case.)
+ - Integrate Paolo Molara's patch to deal with a race in the Darwin
+   thread stopping code.
+ - Changed X86_64 implementation to use SA_SIGINFO in the MPROTECT_VDB
+   implementation.  The old approach appears to have been broken by
+   recent kernels.
+ - Added GC_ATTR_UNUSED to eliminate a warning in gc_allocator.h (Thanks
+   to Andrew Begel.)
+ - Fix GC_task_self declaration in os_dep.c.  (Thanks to Andrew Pinski.)
+ - Increase INITIAL_BUF_SZ in os_dep.c for Solaris /proc reads.
+
+Since gc6.3:
+ - Merge gcconfig.h changes from gcc tree.
+ - Unconditionally include gc_priv.h in solaris_pthreads.c, win32_threads.h,
+   aix_irix_threads.c, and solaris_threads.c to get thread definitions.
+ - Start marker threads in GC_thr_init, so that they get started even
+   if no other threads are ever started.  (Oddly enough, the parallel
+   collector worked correctly, though not well, with no helper threads.)
+ - Go ahead and split large blocks in GC_allochblk_nth if GC_dont_gc
+   is set.  (Thanks to Alexander Petrossian.)
+ - GC_PRINT_BACK_HEIGHT would deadlock with thread support.
+ - Let in_progress_space in backgraph.s grow dynamically.
+ - Fix README.solaris2.  The GC_thr_init() hack doesn't work anymore.
+ - Convert GC_finalizer_mem_freed to bytes in allchblk.c.
+ - Add missing declaration for GC_generic_malloc_words_small_inner.
+   Without it, s390x breaks.  (Thanks to Ulrich Weigand.)
+ - Applied several MacOSX patches to support older tool chains.
+   (Thanks to Stefan Ring.)
+ - Bug fix for NetBSD/amd64.  (Thanks to Marc Recht.)  Add NetBSD/sh3
+   support.  (Thanks to Uchiyama Yasushi.)
+ - Fixed an uninitialized variable in cordprnt.c.  (Thanks to gcc for
+   providing the warning.)
+ - Eliminated some, but not all, gcc -Wall warnings.
+ - Changed some old style casts to reinterpret_cast in new_gc_alloc.h.
+   (Thanks to Dan Grayson.)
+ - GC_extend_size_map shouldn't adjust for GC_all_interior_pointers if
+   GC_DONT_ADD_BYTE_AT_END is set.
+ - Changed some (long) casts to (word) in preparation for win64.
+   (Thanks to Peter Colson.)
+ - Changed "int stack_size" declaration in pthread_support.c to use
+   size_t.  (Only mattered with GC_ASSERTIONS enabled.)
+ - Added CRIS (etrax) support.  (Thanks to Simon Posnjak and
+   Hans-Peter Nilsson.)
+ - Removed GC_IGNORE_FB frame buffer recognition, and replaced
+   it with a check that the mapping type is MEM_IMAGE.
+   In theory, this should work much better, but it is a high
+   risk change for win32.  (Thanks to Ashley Bone for the crucial
+   experimental data behind this, and to Rutger Ovidus for
+   some further experiments.)
+ - GC_allochblk_nth incremented GC_words_wasted by bytes rather than
+   words.
+ - Consider GC_words_wasted in GC_adj_words_allocd only if it is within
+   reason.  (A hack to avoid some extremely unlikely scenarios in which
+   we manage to allocate only "wasted" space.  7.0 has a better fix.)
+ - Changed PowerPC GC_clear implementation to use lwsync instead of
+   eieio, since the documentation recommends against eieio, and
+   it seems to be incorrect if the preceding memory op is a load.
+ - Fixed print_block_list to print the correct kind number for
+   STUBBORN.  (Thanks to Rutger Ovidus.)
+ - Have configure.in generate an error if it is asked to support
+   pthreads, but doesn't know how to.
+ - Added Kazuhiro Inaoka's patch for Renesas M32R support.
+ - Have the GNU build mechanism link with -ldl.  Rename THREADLIBS
+   to THREADDLLIBS to reflect this.  (Thanks to Sven Verdoolaege.)
+ - Added Hannes Mehnert's patch for FreeBSD/SPARC support.
+ - Merged some FreeBSD specific patches to threadlibs.c and dyn_load.c.
+   (Thanks tp John Merryweather Cooper.)
+ - Define MPROTECT_VDB on MACOSX only if threads are being used, since the
+   dirty page tracking mechanism uses threads.  (This avoids an undefined
+   reference to _GC_darwin_register_mach_handler_thread.)
+ - By popular demand, use __libc symbols only if we are built with
+   USE_LIBC_PRIVATES, which is off by default, and not otherwise documented.
+ - Ignore GC_enable_incremental() requests when KEEP_BACK_PTRS is set.
+   The GC itself will dirty lots of pages in this cases, probably making
+   it counterproductive on all platforms.  And the DARWIN port crashes.
+Since gc6.4:
+ - Integrated Paolo Molaro's patch to deal with EINTR in sem_wait.
+ - Make GC_approx_sp() write to dummy location to ensure that stack
+   is grown here, when sp looks reasonable, rather than later, when
+   it might look like a bad memory reference.  (Problem was never
+   observed that I know of.  But on rereading the code it seemed
+   dubious.)
+ - Separate out GC_with_callee_saves_pushed and sometimes call
+   it from GC_suspend_handler in pthread_stop_world.c.  Callee-save
+   register values sometimes failed to get traced under HP/UX on
+   PA-RISC.  Linux/IA64 had the same problem, though non-stacked
+   callee-save registers seem to be so rarely used there that nobody
+   ever noticed.
+ - Integrated an ancient Darwin powerpc_darwin_machine_dep.s patch
+   from Andreas Tobler, which I had lost.
+ - Fix compare_and_exchange implementation for gcc/IA64 to deal with
+   pickier compiler versions.
+ - Fixed Itanium 32-bit ABI support (HP/UX).  In particular, the
+   compare_and_exchange implementation didn't consider that possibility.
+ - Undefine GC_pthread_detach in win32_threads.c.  (Thanks to
+   Tagliapietra Tommaso.)
+ - Fixed inclusion of frame.h for NETBSD in os_dep.c.
+ - Applied Dan Bonachea's patch to use mmap on AIX.
+ - Several fixes to resurrect the Irix port on recent OS versions.
+ - Change ALPHA to use LINUX_STACKBOTTOM.
+ - Change SPARC64/LINUX to also use LINUX_STACKBOTTOM.  Deal with potential
+   bad values of __libc_stack_end on that platform.  (Thanks to David Miller.)
+ - Relax gctest to allow larger heap if ALIGN_DOUBLE isn't set.
+   (Unnecessary in 7.0)
+ - Force a define of __STDC__=0 for the IBM compiler on AIX, so that
+   we get prototypes.  (Unnecessary in 7.0)
+ - GC_INIT definition for AIX and CYGWIN referred to DATASTART and DATAEND
+   which are only defined in private include files.
+ - Integrated some small gcconfig.h patches from Dan Bonachea.  Also
+   relaxed assertion about FreeBSD stack size in pthread_support.c.
+ - Integrated Andrew Begel's darwin_stop_world.c patch for 64-bit
+   support.  This may need additional work.
+ - Avoided potentially infinite recursion in GC_save_callers if
+   the system backtrace calls malloc.  The workaround currently requires
+   __thread support if this code is used with threads.
+ - Avoided another similar infinite recursion by conditionally
+   invoking GC_save_callers in alloc.c.  (Thanks to Matthias Andree
+   for helping to track down both of these.)
+ - Removed all traces of aix_irix_threads.c.  AIX and Irix now use
+   pthread_support.c and pthread_stop_world.c.  The old code appeared
+   to be unreliable for AIX, and was not regularly maintained.
+ - On Irix, ignore segments with MA_FETCHOP or MA_NOTCACHED attributed;
+   they're not always safe to read.
+ - Fixed a previously vacuous assertion (diagnosed by the SGI compiler)
+   in GC_remove_from_fl.
+ - Fix stack_size assertion in GC_pthread_create.
+ - Fix assertion in GC_steal_mark_stack.
+
+Since gc6.5:
+ - Fix CPU count detection for Irix and FreeBSD. (Thanks to Dan Bonachea.)
+ - Integrate Dan Bonachea's patch for the IBM XLC compiler on Darwin.
+ - Integrated Andreas Tobler's FreeBSD/PowerPC patch.
+ - Don't access the GC thread structure from the restart handler.  It's
+   unsafe, since the handler may run too late.  (Thanks to Ben Maurer for
+   tracking this down.)
+ - Applied Christian Thalinger's patch to change comment syntax in
+   alpha_mach_dep.S.
+ - Added test for GC_no_dls in GC_dyld_image_add for DARWIN. (Thanks to
+   Juan Jose Garcia Ripoli).
+ - Use LINUX_STACKBOTTOM for Linux/SH and LINUX/ARM. (Thanks to Sugioka
+   Toshinobu and Christian Thalinger.)
+ - Rewrote GC_parse_map_entry.  This assumed a fixed column layout of
+   /proc/self/maps on Linux.  This ceased to be true about 2 years ago.
+   The old code is probably quite problemetic with -DREDIRECT_MALLOC.  It
+   is also used by default for IA64, though I haven't seen actual failures
+   there.
+ - More consistently define HBLKSIZE to 4096 on 64 bit architectures with
+   4K pages.  (Thanks to Andrew Haley.)
+ - With win32 threads, GC_stop_world needs to acquire GC_write_cs.  (Thanks
+   to Ben Hutchings for the observation and patch.)
+ - Move up struct callinfo declaration to make gcc 4.0.2. happy.
+
+Since 6.6:
+ - Add "int" to Solaris "end" and "etext" declaration in gc.h.  Declared
+   the symbols with underscores and as arrays, since that's what's actually
+   used.  Perhaps this could all just be removed?  (Thanks to John Bowman.)
+ - Fixed ARM GC_test_and_set code.  (Thanks to Kazu Hirata and Paul Brook.)
+ - Added casts for assignments to hb_last_reclaimed, which truncate the
+   value.  Added a cast to GC_adj_words_allocd.  Use GetModuleHandleA
+   when retrieving a handle to kernel32.dll under win32.  (Thanks to the
+   Visual Prolog developers.)
+ - Added Tandem S-Series support.  (Thanks to Craig McDaniel.  A modified
+   version of his patch was applied, and hence breakage is probably not
+   his fault.)
+ - Remove spurious gc:: qualifier for operator delete[] in gc_cpp.h.
+   (Thanks to Hanno Boeck.)
+ - Changed a test for LINUX in config_macros.h to one for __linux__.
+ - Add prototypes for GC_finalizer_notifier and GC_thr_init.  (Thanks to
+   David Ayers.)
+ - Use ld instead of nonexitent ldz instruction in Darwin FindTopOfStack.
+   (Thanks to Andreas Tobler.)
+ - Add support for Darwin/X86.  (Thanks to Geoff Norton and the Mono
+   developers.)
+ - Merge in some recent gcc fixes.  Add ppc64 asm code.  (Thanks to Bryce
+   McKinley and other gcj developers.)
+ - Scan MEM_PRIVATE sections under Windows ME and predecessors.
+ - Interior pointers with some largish offsets into large objects could
+   be ignored, if GC_all_interior_pointers was set.  (Oddly this worked
+   correctly for stack references if it was not set.  Otherwise it failed
+   for both stack and heap references.)  Thanks to Andrew McKinlay for the
+   critical test case.
+ - Integrated Tatsuya Bizenn's NETBSD threads support, with some
+   untested changes.
+ - Added GC_strdup and friends to make leak detection work correctly
+   for strdup clients.  (Thanks to Jon Moore.)  Fixed the existing strdup
+   with malloc redirection to handle a null malloc return correctly.
+
+Since gc6.7:
+ - Added some support for Dragonfly BSD.  (Thanks to Joerg Sonnenberger and
+   Thomas Klausner.)
+ - Improvements to the HP/UX section of configure.in/configure.ac.
+   (Thanks to Andreas Tobler)
+ - GC_unix_get_mem could neglect to release the malloc lock on Irix, under
+   extremely unlikely circumstances.  Thanks to Jean-Baptiste Nivois for
+   some careful code reading.
+ - Added support for kFreeBSD + glibc (Thanks to Petr Salinger)
+ - Fix more MacOS threads memory leaks (Thanks to Allan Hsu)
+ - Added initial Solaris/X86-64 support (Thanks to Rainer Orth)
+
+Since gc6.8:
+ - Fix typo in PREFETCH implementation for X86_64.  (Thanks to Peter Wang.)
+ - Fix M68K LINUX port. (Thanks to Debian packagers.)
+ - __GNUC__ was misspelled as __GNUC in new_gc_alloc.h. (Thanks to Peter Wang.)
+ - Integrated Allan Hsu's patch for OS X VM deallocation problems.
+ - Applied FreeBSD/X86_64 patch.
+
+Since gc6.9:
+ - Remove GC_PROTO, VOLATILE, GC_PTR, and GC_CONST.  Assume ANSI C compiler
+   and use ANSI constructs unconditionally.
+ - Introduce #elif and #error in some of the appropriate places.
+ - Remove GC_printf cruft. Use stdargs.
+ - Remove separate Solaris threads support.  Use the more generic Posix
+   implementation.
+ - Use atomic_ops for atomic operations and memory barriers.
+ - Clean up MPROTECT_VDB implementation.  Use SA_SIGINFO wherever
+   possible.
+ - Remove broken SIGNALS stuff.
+ - Use size_t instead of word, where appropriate.
+ - Add .S.o rule to Makefile.am.
+ - Officially unsupport SunOS4, several old flavors of M68K (SunOS4,
+   A/UX, HP), IBM PC/RTs and RISCOS/Irix4.  (I doubt the old code worked.
+   If anyone cares, these should be easy to resurrect.)
+ - Add EXPECT() in some critical places.
+ - Redefined hb_sz and hb_body to deal with bytes rather than words.
+   This affected a great deal of code.  I would like to consistently use
+   byte offsets and sizes where there's not a convincing reason to do
+   otherwise.
+ - Redefined several other variables (GC_mem_found, GC_words_allocd)
+   etc. to use units of bytes.  Most of these were also renamed to
+   reflect that fact.
+ - Killed as many "register" declarations as possible.
+ - Partially replaced stubborn allocation with manual write barrier.
+   It's currently broken.
+ - Restructured mark code, to allow mark bits to be kept either on
+   a per allocation granule or per object basis.  The emphasis is
+   now on the -DUSE_MARK_BYTES option, since individual bits perform
+   quite badly on hyperthreaded P4s, and are probably suboptimal on
+   other architectures.  -DUSE_MARK_BITS is currently broken, and may
+   be resurrected only for the single-threaded case.  This significantly
+   reduced the cache footprint required by auxiliary GC data structures.
+   It also reduces space overhead for small heaps.  It probably slows
+   things down slightly if interior pointers are very common.
+ - As part of the above, we now maintain an approximate count of set
+   mark bits in each heap block.
+ - As part of the above, the semantics of hb_map changed drastically.
+   For MARK_BIT_PER_OBJ, it doesn't exist.  For MARK_BIT_PER_GRANULE,
+   it is purely a way to replace a mod instruction with a table lookup.
+   (Somewhat to my surprise, this still wins on modern hardware.)
+ - Removed PRINTSTATS, GATHERSTATS, and SILENT macros.  Everything is
+   now controlled by GC_print_stats variable and GC_PRINT_STATS
+   and new GC_PRINT_VERBOSE_STATS environment variables.
+ - Add GC_log_printf and use it consistently for logging output.
+ - Unconditionally count the objects we reclaim in the sweep phase.
+   For thread local allocation, we need that anyway, and we expect
+   that's increasingly the only case that matters.  And it simplifies
+   the code.  In general expect minor performance hacks that benefit
+   only the single-threaded case to disappear.
+ - Remove GC_quiet from gc.h and elsewhere.
+ - Changed the heap expansion heuristic, and the definition of
+   GC_free_space_divisor, to refer to live data size, instead of total
+   heap size.  I believe this is much more robust.  It wasn't previously
+   possible, because we didn't have access to live data size.
+ - Thread local allocation added the extra byte in twice: Once in
+   thread_local_alloc, and once in malloc_many.
+ - Removed GC_malloc_words_small and GC_gcj_fast_malloc.  A new
+   mechanism based on the thread local allocation data structures
+   is expected to be added instead.  This should allow inlined code
+   that is both fast and doesn't rely on collector internals.
+ - Changed both free lists and reclaim lists to be indexed by granules
+   instead of words, norming halving their size.
+ - MERGE_SIZE is now the only option, and the macro was removed.
+   (Without it, we need a memory reference to GC_all_interior_pointers
+   anyway.  Thus it costs us nothing.)
+ - Change GC_size_map to map to granules instead of words.  Make sure
+   that every possible size up to TINY_FREELISTS is present.
+ - Split of macros need for fast inline allocation into gc_tiny_fl.h
+   in anticipation of a new inline allocator that doesn't rely on GC
+   internals.
+ - Changed thread local allocation to use GRANULE_BYTES and TINY_FREELISTS
+   in anticipation of a merge with the inline allocation code.
+ - Removed ALIGN_DOUBLE.  This is mostly handled by GRANULE_BYTES.
+ - Make locking on most platforms conditional on GC_need_to_lock.
+
+Since gc7.0alpha1:
+ - GC_bytes_allocd was incremented by a possibly uninitialized variable
+   in GC_generic_malloc_inner.  (Bug introduced in gc7.0alpha1.  Thanks
+   to Ben Hutchings for tracking it down.)
+ - Win32 fixes.  (Thanks to Ben Hutchings and Maurizio Vairani.)
+ - Integrated Ben Hutchings' GetWriteWatch-based virtual dirty bit
+   implementation for win32.
+ - Removed pc_gc.tar and floppy targets in Makefile.direct.  Removed
+   pc_excludes file.
+ - No longer include GC_bytes_wasted when evaluating allocation progress.
+   Since we are now counting live memory, it no longer makes sense.
+ - Applied Davide Angelocola's configury patch.  There are now separate
+   Makefile.am's in the cord and tests subdirectory, more tests, etc.
+ - Renamed configure.in to configure.ac.
+ - Merged a very small number of Nathanael Nerode's configure.ac
+   cleanups from the gcc tree.  Unfortunately, that file is a bit
+   different from ours.
+ - Changed EINTR handling in sem_wait slightly.
+ - Restructure the root marking code.  Remove all traces of
+   USE_GENERIC_PUSH_REGS, and effectively make it the default.
+   Make it easier to pass a context pointer to the mark routine, in
+   case we ever want to do precise stack marking.
+ - Replace GC_start_blocking() and GC_end_blocking() with GC_do_blocking().
+   This remains undocumented, and only implemented for pthreads.  But it
+   removes an otherwise unavoidable race with stores of callee-save
+   registers.
+ - Fix GC_n_mark_bits for the default MARK_BIT_PER_GRANULE case.  This
+   resulted in bogus complaints in heap dumps.
+ - Upgrade to libatomic_ops-1.0, and update build structure to match.
+ - Remove SRC_M3 support. Clean up lock initialization code in misc.c.
+ - Removed gc_local_alloc.h.  If THREAD_LOCAL_ALLOC is defined, the
+   thread local allocation routines are now called automatically.
+ - Renamed gc_inl.h back to gc_inline.h.  Changed the interface appreciably
+   since locking has turned into a dominant issue, and in-line allocation
+   only makes sense if it's no worse than thread-local allocation.
+   Gc_inline.h is now also used to implement thread-local allocation.
+ - Finished replacing stubborn allocation with manual write barrier.
+   Untested.
+ - Use thread-local allocation code by default.
+ - Added GC_register_my_thread and friends for Posix and win32.
+ - Patch for GWW_VDB from Ben Hutchings.
+ - Removed explicit THREAD_LOCAL_ALLOC tests, since that now always
+   redefines GC_malloc.
+ - Removed now unused AIX memory allocation code.
+ - Various minor fixes for bugs introduced in 7.0alpha1.
+
+Since gc7.0alpha2
+ - Added support for dlopen-based interception of pthread functions.
+   This is only half done.  The gc.h redefinitions currently interfere.
+ - Integrated major automake overhaul from Petter Urkedal.
+
+Since gc7.0alpha3
+   (various 6.5, 6.6 changes)
+ - Removed GC_brief_async_signal_safe_sleep and used atomic_ops instead.
+   (Thanks to Ben Maurer.)
+ - Integrated build patches from David Angelocola and Petter Urkedal.
+ - Fix dynamic-linker-based pthread call redirection.
+ - Renamed RS6000 to POWERPC/AIX.
+ - Allow recovery from SIGSEGV in marker on Linux.  This works around
+   a race in thread stack marking if /proc is used to find roots.  We do
+   that by default with malloc redirection and threads.  This involved
+   moving some GC_find_limit and SETJMP related declarations to gc_priv.h.
+ - Added doc/porting.html file.
+ - Added ADD_HEAP_GUARD_PAGES for sbrk/*nix platforms to debug extreme
+   memory overwrite errors.
+ - Added trivial NO_INCREMENTAL flag to facilitate debugging.
+ - Added GC_getattr_np-based GC_get_stack_base (untested).
+ - Separated thread local allocation into a separate file and added the
+   beginning of win32 support for that.
+
+Since gc7.0alpha4
+   (more 6.6, 6.7 changes)
+ - Some Solaris fixes, including some more general changes in how
+   the assembly pieces of mach_dep.c are handled.
+ - Removed a lot of SOLARIS_THREADS-specific code that was only
+   needed with the old implementation.  This included many (mostly no-op)
+   versions of GC_is_fresh.
+ - Don't use atomic_ops in gc_locks.h unless we need threads.
+ - Fixed USE_MARK_BITS, which is once againthe default without PARALLEL_MARK.
+ - Removed Solaris GC_INIT hack.  It's a workaround for a long dead bug,
+   and it seemed to be wrong anyway.
+ - Changed win32_threads.c to require preprocessor-based interception
+   of thread routines by default.  A client call to GC_use_DllMain is
+   now required to get the old behavior in which DllMain is used to implicitly
+   register threads.  This was doen for uniformity with other platforms, and
+   because the DllMain solution seemed to require very tricky code which,
+   at least in the past, imposed hard bounds onthe number of threads.
+ - Many small changes to make thread support work again on Cygwin.
+ - Moved definition of allocator lock etc. to pthread_support.c and
+   win32_threads.c for those two cases.
+ - Got rid of the FASTLOCK() machinery.  It doesn't seem useful on modern
+   platforms.
+ - Cleaned up the uncollectable allocation routines, speeding up the
+   slower paths.  The code did enough unnecessary work off the critical path
+   that the underlying logic was getting hard to extract.
+ - No longer turn off THREAD_LOCAL_ALLOC with DBG_HDRS_ALL.  Indications
+   are it just works, and I think the reasons for it not working disappeared
+   a while ago.
+ - Fixed bugs in hb_n_marks calculation and assertion.
+ - Don't use __builtin_expect for pre-3.0 gcc.
+ - Define GWW_VDB only for recent Microsoft tool chains.
+ - Add overview.html to doc directory.
+ - Fix NT_STATIC_THREADS_MAKEFILE, various compiler warnings.
+ - Made thread local allocation sort of work with Cygwin.  The code should
+   be there to deal with other Windows variants, But non-Cygwin Windows
+   threads need more bug fixes.
+
+Since gc7.0alpha5
+   (more 6.7 changes)
+ - Declare GC_dump() in gc.h.
+ - Add --enable-large-config, which just defines the LARGE_CONFIG macro.
+ - Make GlobalAlloc address alignment a bit more intuitive.  (Thanks to
+   Charles Mills.)
+ - Use #elif in the definitions of GET_MEM.
+ - Overhaul porting.html.  Remove corresponding text from README.
+ - Fix typo in DARWIN section of gcconfig.h.
+ - Fix Darwin thread memory leak.  (Thanks to Bruce Mitchener.)
+ - Update x86 AO_test_and_set implementation to use "=q".
+ - Add $(EXEEXT) to many tests in tests/tests.am.  (Corresponds to a
+   6.7 fix, which no longer applied.)
+ - Fix Darwin/PPC port.
+ - Fix Cygwin/threads port.
+ - Fix gcj malloc support.
+ - For GNU-style make, don't build libatomic_ops unless threads are requested.
+   This should allow single-threaded builds on platforms which do not
+   currently support libatomic_ops.
+ - Clean up and hopefully fix the CFLAGS calculation for GNU build.
+   (Substantially improves things on HP/UX.)
+ - Integrated Andrei Polushin's Visual C++ patches.  These provide for
+   stack traces, better C++ debug support, and better log file handling.
+   Note that these change the location of the log file to a the path of the
+   executable with a .log extension.  To get the old behavior back, define
+   OLD_WIN32_LOG_FILE.  For the time being, I'm checking his project
+   files and the like into a windows-untested subdirectory.  They
+   are almost certainly already out of date, but better than what we had
+   before.
+ - Fixed some win32 threads bugs, and added support for _beginthreadex.
+ - Fix zero size thread local allocation so that explicit deallocation
+   works correctly.
+ - Removed serious bug in GC_malloc_uncollectable(large size).
+ - Do not try to do thread-local gcj allocation in incremental mode.  There
+   are races in setting up the descriptor.
+ - Add GC_INIT() to middle.c, fix some more GC_printfn calls.
+ - Some assertions erroneously used I_HOLD_LOCK() negatively, eventhough
+   it can now spuriously return TRUE.
+ - Rename SUNOS5 macro and OS name to SOLARIS and SUNOS5DL to SOLARISDL.
+ - On Linux and some Un*x variants, allocate memory by first trying sbrk,
+   and then switching to mmap if that fails.
+ - Fixed /proc/x/maps reading to deal with asynchronous deletions.
+ - Fix REDIRECT_MALLOC with threads on Linux.  It now usually seems to work
+   with ugly hacks that include having calloc behave differently when it is
+   called from ld.so or the pthreads library.  A reasonable amount of
+   infrastructure was added to support some of this.  Thanks to Roland McGrath
+   for ideas and information.
+ - Import various updated build scripts.
+ - Add GC_register_has_static_roots_callback.  (Thanks to Andrew Haley.)
+ - Fix serious bugs in GC_malloc_atomic_uncollectable().

+[gc7.0alpha7 was released and version bumped to gc7.0alpha8]
+
+Since first gc7.0alpha8 version:
+ [ Some gc6.9 changes ]
+ - Change FindTopOfStack decl in darwin_stop_world.c.
+ - Move some static tests from misc.c to gcconfig.h.  Use #error.
+ - Add GC_print_free_list() function.  (Thanks to Bruce Hoult.)
+ - Add GC_GNU_THREADS support on HURD. (Thanks to Aleksey Demakov,
+   Barry DeFreese, and possibly other Debian maintainers.)
+ - __GNUC__ was misspelled as __GNUC in thread_local_alloc.h.
+   (Thanks to Peter Wang.)
+ - Integrated various MacOSX patches and tried to reconcile them.
+   Thanks to Allan Hsu, several contributers at Apple, and probably
+   others.
+ - Added some casts to powerpc.h in libatomic_ops to silence warnings.
+
+FOR FURTHER UPDATES SEE ../ChangeLog FILE.
+  
+To do:
+ - REDIRECT_MALLOC and threads combination should work on more platforms,
+   and needs more testing on Linux.
+ - Clone marker inner loop to support arch-dependent prefetching,
+   and counting of objects marked for finalization.
+ - The USE_MUNMAP code should really use a separate data structure
+   indexed by physical page to keep track of time since last use of
+   a page.  Using hblk headers means we lose track of ages when
+   blocks are merged, and we can't unmap pages that have been allocated and
+   dropped by the blacklisting code.  I suspect both of these matter.
+ - A dynamic libgc.so references dlopen unconditionally, but doesn't link
+   against libdl.
+ - GC_proc_fd for Solaris is not correctly updated in response to a
+   fork() call.  Thus incremental collection in the child won't work
+   correctly.  (Thanks to Ben Cottrell for pointing this out.)
+ - --enable-redirect-malloc is mostly untested and known not to work
+   on some platforms. 
+ - There seem to be outstanding issues on Solaris/X86, possibly with
+   finding the data segment starting address.  Information/patches would
+   be appreciated.
+ - Very large root set sizes (> 16 MB or so) could cause the collector
+   to abort with an unexpected mark stack overflow.  (Thanks again to
+   Peter Chubb.)  NOT YET FIXED.  Workaround is to increase the initial
+   size.
+ - The SGI version of the collector marks from mmapped pages, even
+   if they are not part of dynamic library static data areas.  This
+   causes performance problems with some SGI libraries that use mmap
+   as a bitmap allocator.  NOT YET FIXED.  It may be possible to turn
+   off DYNAMIC_LOADING in the collector as a workaround.  It may also
+   be possible to conditionally intercept mmap and use GC_exclude_static_roots.
+   The real fix is to walk rld data structures, which looks possible.
+ - Incremental collector should handle large objects better.  Currently,
+   it looks like the whole object is treated as dirty if any part of it
+   is.

+This is an attempt to acknowledge early contributions to the garbage
+collector.  Later contributions should instead be mentioned in
+README.changes.
+
+HISTORY -
+
+  Early versions of this collector were developed as a part of research
+projects supported in part by the National Science Foundation
+and the Defense Advance Research Projects Agency.
+
+The garbage collector originated as part of the run-time system for
+the Russell programming language implementation. The first version of the
+garbage collector was written primarily by Al Demers.  It was then refined
+and mostly rewritten, primarily by Hans-J. Boehm, at Cornell U., 
+the University of Washington, Rice University (where it was first used for
+C and assembly code), Xerox PARC, SGI, and HP Labs.  However, significant
+contributions have also been made by many others.
+
+Some other contributors:  
+
+More recent contributors are mentioned in the modification history in
+README.changes.  My apologies for any omissions.
+
+The SPARC specific code was originally contributed by Mark Weiser.
+The Encore Multimax modifications were supplied by
+Kevin Kenny (kenny@m.cs.uiuc.edu).  The adaptation to the IBM PC/RT is largely
+due to Vernon Lee, on machines made available to Rice by IBM.
+Much of the HP specific code and a number of good suggestions for improving the
+generic code are due to Walter Underwood.
+Robert Brazile (brazile@diamond.bbn.com) originally supplied the ULTRIX code.
+Al Dosser (dosser@src.dec.com) and Regis Cridlig (Regis.Cridlig@cl.cam.ac.uk)
+subsequently provided updates and information on variation between ULTRIX
+systems.  Parag Patel (parag@netcom.com) supplied the A/UX code.
+Jesper Peterson(jep@mtiame.mtia.oz.au), Michel Schinz, and
+Martin Tauchmann (martintauchmann@bigfoot.com) supplied the Amiga port.
+Thomas Funke (thf@zelator.in-berlin.de(?)) and
+Brian D.Carlstrom (bdc@clark.lcs.mit.edu) supplied the NeXT ports.
+Douglas Steel (doug@wg.icl.co.uk) provided ICL DRS6000 code.
+Bill Janssen (janssen@parc.xerox.com) supplied the SunOS dynamic loader
+specific code. Manuel Serrano (serrano@cornas.inria.fr) supplied linux and

+Dave Detlefs(detlefs@src.dec.com) also provided several generic bug fixes.
+Alistair G. Crooks(agc@uts.amdahl.com) supplied the NetBSD and 386BSD ports.
+Jeffrey Hsu (hsu@soda.berkeley.edu) provided the FreeBSD port.
+Brent Benson (brent@jade.ssd.csd.harris.com) ported the collector to

+Ari Huttunen (Ari.Huttunen@hut.fi) generalized the OS/2 port to
+nonIBM development environments (a nontrivial task).
+Patrick Beard (beard@cs.ucdavis.edu) provided the initial MacOS port.

+Darwin/MacOSX Support - December 16, 2003
+=========================================
+
+Build Notes
+===========
+
+Building can be done with autoconf as normal. If you want to build
+a Universal library using autoconf, you need to disable dependency
+tracking and specify your desired architectures in CFLAGS:
+
+CFLAGS="-arch ppc -arch i386 -arch x86_64" ./configure --disable-dependency-tracking
+
+
+Important Usage Notes
+=====================
+
+GC_init() MUST be called before calling any other GC functions. This
+is necessary to properly register segments in dynamic libraries. This
+call is required even if you code does not use dynamic libraries as the
+dyld code handles registering all data segments.
+
+When your use of the garbage collector is confined to dylibs and you
+cannot call GC_init() before your libraries' static initializers have
+run and perhaps called GC_malloc(), create an initialization routine
+for each library to call GC_init():
+
+#include <gc/gc.h>
+extern "C" void my_library_init() { GC_init(); }
+
+Compile this code into a my_library_init.o, and link it into your
+dylib. When you link the dylib, pass the -init argument with
+_my_library_init (e.g. gcc -dynamiclib -o my_library.dylib a.o b.o c.o
+my_library_init.o -init _my_library_init). This causes
+my_library_init() to be called before any static initializers, and
+will initialize the garbage collector properly.
+
+Note: It doesn't hurt to call GC_init() more than once, so it's best,
+if you have an application or set of libraries that all use the
+garbage collector, to create an initialization routine for each of
+them that calls GC_init(). Better safe than sorry.
+
+The incremental collector is still a bit flaky on darwin. It seems to
+work reliably with workarounds for a few possible bugs in place however
+these workaround may not work correctly in all cases. There may also
+be additional problems that I have not found.
+
+Thread-local GC allocation will not work with threads that are not
+created using the GC-provided override of pthread_create(). Threads
+created without the GC-provided pthread_create() do not have the
+necessary data structures in the GC to store this data.
+
+
+Implementation Information
+==========================
+Darwin/MacOSX support is nearly complete. Thread support is reliable on
+Darwin 6.x (MacOSX 10.2) and there have been reports of success on older
+Darwin versions (MacOSX 10.1). Shared library support had also been
+added and the gc can be run from a shared library.
+
+Thread support is implemented in terms of mach thread_suspend and
+thread_resume calls. These provide a very clean interface to thread
+suspension. This implementation doesn't rely on pthread_kill so the
+code works on Darwin < 6.0 (MacOSX 10.1). All the code to stop and
+start the world is located in darwin_stop_world.c.
+
+Since not all uses of the GC enable clients to override pthread_create()
+before threads have been created, the code for stopping the world has
+been rewritten to look for threads using Mach kernel calls. Each
+thread identified in this way is suspended and resumed as above. In
+addition, since Mach kernel threads do not contain pointers to their
+stacks, a stack-walking function has been written to find the stack
+limits. Given an initial stack pointer (for the current thread, a
+pointer to a stack-allocated local variable will do; for a non-active
+thread, we grab the value of register 1 (on PowerPC)), it
+will walk the PPC Mach-O-ABI compliant stack chain until it reaches the
+top of the stack. This appears to work correctly for GCC-compiled C,
+C++, Objective-C, and Objective-C++ code, as well as for Java
+programs that use JNI. If you run code that does not follow the stack
+layout or stack pointer conventions laid out in the PPC Mach-O ABI,
+then this will likely crash the garbage collector.
+
+The original incremental collector support unfortunately no longer works
+on recent Darwin versions. It also relied on some undocumented kernel
+structures. Mach, however, does have a very clean interface to exception
+handing. The current implementation uses Mach's exception handling.
+
+Much thanks goes to Andrew Stone, Dietmar Planitzer, Andrew Begel,
+Jeff Sturm, and Jesse Rosenstock for all their work on the
+Darwin/OS X port.

+gc_cpp.h usage
+==============
+
+Replacement of operator new and delete is apparently not supported with
+dynamic libraries.  This means that applications using gc_cpp.h
+(including the built-in test) will probably not work correctly with
+the collector in a dynamic library, unless special care is taken.

+
+
+Older Information (Most of this no longer applies to the current code)
+======================================================================
+
+While the GC should work on MacOS X Server, MacOS X and Darwin, I only tested
+it on MacOS X Server.
+I've added a PPC assembly version of GC_push_regs(), thus the setjmp() hack is
+no longer necessary. Incremental collection is supported via mprotect/signal.
+The current solution isn't really optimal because the signal handler must decode
+the faulting PPC machine instruction in order to find the correct heap address.
+Further, it must poke around in the register state which the kernel saved away
+in some obscure register state structure before it calls the signal handler -
+needless to say the layout of this structure is no where documented.
+Threads and dynamic libraries are not yet supported (adding dynamic library
+support via the low-level dyld API shouldn't be that hard).
+
+The original MacOS X port was brought to you by Andrew Stone.

+
+Note from Andrew Begel:
+
+One more fix to enable gc.a to link successfully into a shared library for
+MacOS X. You have to add -fno-common to the CFLAGS in the Makefile. MacOSX
+disallows common symbols in anything that eventually finds its way into a
+shared library. (I don't completely understand why, but -fno-common seems to
+work and doesn't mess up the garbage collector's functionality).
+
+Feb 26, 2003
+
+Jeff Sturm and Jesse Rosenstock provided a patch that adds thread support.
+GC_MACOSX_THREADS should be defined in the build and in clients.  Real
+dynamic library support is still missing, i.e. dynamic library data segments
+are still not scanned.  Code that stores pointers to the garbage collected
+heap in statically allocated variables should not reside in a dynamic
+library.  This still doesn't appear to be 100% reliable.
+
+Mar 10, 2003
+Brian Alliet contributed dynamic library support for MacOSX.  It could also
+use more testing.

+                                specified with a multiplier ('k', 'M' or 'G')
+                                suffix.
+
+GC_MAXIMUM_HEAP_SIZE=<bytes> - Maximum collected heap size.  Allows
+                               a multiplier suffix.
+
+GC_LOOP_ON_ABORT - Causes the collector abort routine to enter a tight loop.
+                   This may make it easier to debug, such a process, especially
+                   for multi-threaded platforms that don't produce usable core
+                   files, or if a core file would be too large.  On some
+                   platforms, this also causes SIGSEGV to be caught and
+                   result in an infinite loop in a handler, allowing
+                   similar debugging techniques.
+
+GC_PRINT_STATS - Turn on GC logging.  Not functional with SMALL_CONFIG.
+
+GC_LOG_FILE - The name of the log file.  Stderr by default.  Not functional
+              with SMALL_CONFIG.
+
+GC_ONLY_LOG_TO_FILE - Turns off redirection of GC stdout and stderr to the log
+                      file specified by GC_LOG_FILE.  Has no effect unless
+                      GC_LOG_FILE is set.  Not functional with SMALL_CONFIG.
+
+GC_PRINT_VERBOSE_STATS - Turn on even more logging.  Not functional with
+                         SMALL_CONFIG.
+
+GC_DUMP_REGULARLY - Generate a GC debugging dump GC_dump() on startup
+                    and during every collection.  Very verbose.  Useful
+                    if you have a bug to report, but please include only the
+                    last complete dump.
+
+GC_BACKTRACES=<n> - Generate n random back-traces (for heap profiling) after
+                    each GC.  Collector must have been built with
+                    KEEP_BACK_PTRS.  This won't generate useful output unless
+                    most objects in the heap were allocated through debug
+                    allocators.  This is intended to be only a statistical
+                    sample;  individual traces may be erroneous due to
+                    concurrent heap mutation.
+
+GC_PRINT_ADDRESS_MAP - Linux only.  Dump /proc/self/maps, i.e. various address
+                       maps for the process, to stderr on every GC.  Useful for
+                       mapping root addresses to source for deciphering leak
+                       reports.
+
+GC_NPROCS=<n> - Linux w/threads only.  Explicitly sets the number of processors
+                that the GC should expect to use.  Note that setting this to 1
+                when multiple processors are available will preserve
+                correctness, but may lead to really horrible performance,
+                since the lock implementation will immediately yield without
+                first spinning.
+
+GC_MARKERS=<n> - Only if compiled with PARALLEL_MARK.  Set the number
+                of marker threads.  This is normally set to the number of
+                processors.  It is safer to adjust GC_MARKERS than GC_NPROCS,
+                since GC_MARKERS has no impact on the lock implementation.
+
+GC_NO_BLACKLIST_WARNING - Prevents the collector from issuing
+                warnings about allocations of very large blocks.
+                Deprecated.  Use GC_LARGE_ALLOC_WARN_INTERVAL instead.
+
+GC_LARGE_ALLOC_WARN_INTERVAL=<n> - Print every nth warning about very large
+                block allocations, starting with the nth one.  Small values
+                of n are generally benign, in that a bounded number of
+                such warnings generally indicate at most a bounded leak.
+                For best results it should be set at 1 during testing.
+                Default is 5.  Very large numbers effectively disable the
+                warning.
+
+GC_IGNORE_GCJ_INFO - Ignore the type descriptors implicitly supplied by
+                     GC_gcj_malloc and friends.  This is useful for debugging
+                     descriptor generation problems, and possibly for
+                     temporarily working around such problems.  It forces a
+                     fully conservative scan of all heap objects except
+                     those known to be pointer-free, and may thus have other
+                     adverse effects.
+
+GC_PRINT_BACK_HEIGHT - Print max length of chain through unreachable objects
+                     ending in a reachable one.  If this number remains
+                     bounded, then the program is "GC robust".  This ensures
+                     that a fixed number of misidentified pointers can only
+                     result in a bounded space leak.  This currently only
+                     works if debugging allocation is used throughout.
+                     It increases GC space and time requirements appreciably.
+                     This feature is still somewhat experimental, and requires
+                     that the collector have been built with MAKE_BACK_GRAPH
+                     defined.  For details, see Boehm, "Bounding Space Usage
+                     of Conservative Garbage Collectors", POPL 2001, or
+                     http://lib.hpl.hp.com/techpubs/2001/HPL-2001-251.html .
+
+GC_RETRY_SIGNALS, GC_NO_RETRY_SIGNALS - Try to compensate for lost
+                     thread suspend signals in linux_threads.c.  On by
+                     default for GC_OSF1_THREADS, off otherwise.  Note
+                     that this does not work around a possible loss of
+                     thread restart signals.  This seems to be necessary for
+                     some versions of Tru64.  Since we've previously seen
+                     similar issues on some other operating systems, it
+                     was turned into a runtime flag to enable last-minute
+                     work-arounds.
+
+GC_USE_GETWRITEWATCH=<n> - Only if MPROTECT_VDB and GWW_VDB are both defined
+                     (Win32 only).  Explicitly specify which strategy of
+                     keeping track of dirtied pages should be used.
+                     If n=0 then GetWriteWatch() is not used (falling back to
+                     protecting pages and catching memory faults strategy)
+                     else the collector tries to use GetWriteWatch-based
+                     strategy (GWW_VDB) first if available.
+
+GC_DISABLE_INCREMENTAL - Ignore runtime requests to enable incremental GC.
+                     Useful for debugging.
+
+The following turn on runtime flags that are also program settable.  Checked
+only during initialization.  We expect that they will usually be set through
+other means, but this may help with debugging and testing:
+
+GC_ENABLE_INCREMENTAL - Turn on incremental collection at startup.  Note that,
+                     depending on platform and collector configuration, this
+                     may involve write protecting pieces of the heap to
+                     track modifications.  These pieces may include
+                     pointer-free objects or not.  Although this is intended
+                     to be transparent, it may cause unintended system call
+                     failures.  Use with caution.
+
+GC_PAUSE_TIME_TARGET - Set the desired garbage collector pause time in msecs.
+                     This only has an effect if incremental collection is
+                     enabled.  If a collection requires appreciably more time
+                     than this, the client will be restarted, and the collector
+                     will need to do additional work to compensate.  The
+                     special value "999999" indicates that pause time is
+                     unlimited, and the incremental collector will behave
+                     completely like a simple generational collector.  If
+                     the collector is configured for parallel marking, and
+                     run on a multiprocessor, incremental collection should
+                     only be used with unlimited pause time.
+
+GC_FULL_FREQUENCY - Set the desired number of partial collections between full
+                    collections.  Matters only if GC_incremental is set.
+                    Not functional with SMALL_CONFIG.
+
+GC_FREE_SPACE_DIVISOR - Set GC_free_space_divisor to the indicated value.
+                      Setting it to larger values decreases space consumption
+                      and increases GC frequency.
+
+GC_UNMAP_THRESHOLD - Set the desired memory blocks unmapping threshold (the
+                   number of sequential garbage collections for which
+                   a candidate block for unmapping should remain free).  The
+                   special value "0" completely disables unmapping.
+
+GC_FORCE_UNMAP_ON_GCOLLECT - Turn "unmap as much as possible on explicit GC"
+                mode on (overrides the default value).  Has no effect on
+                implicitly-initiated garbage collections.  Has no effect if
+                memory unmapping is disabled (or not compiled in) or if the
+                unmapping threshold is 1.
+
+GC_FIND_LEAK - Turns on GC_find_leak and thus leak detection.  Forces a
+               collection at program termination to detect leaks that would
+               otherwise occur after the last GC.
+
+GC_FINDLEAK_DELAY_FREE - Turns on deferred freeing of objects in the
+                       leak-finding mode (see the corresponding macro
+                       description for more information).
+
+GC_ABORT_ON_LEAK - Causes the application to be terminated once leaked or
+                   smashed objects are found.
+
+GC_ALL_INTERIOR_POINTERS - Turns on GC_all_interior_pointers and thus interior
+                           pointer recognition.
+
+GC_DONT_GC - Turns off garbage collection.  Use cautiously.
+
+GC_USE_ENTIRE_HEAP - Set desired GC_use_entire_heap value at start-up.  See
+                     the similar macro description in README.macros.
+
+GC_TRACE=addr - Intended for collector debugging.  Requires that the collector
+                have been built with ENABLE_TRACE defined.  Causes the debugger
+                to log information about the tracing of address ranges
+                containing addr.  Typically addr is the address that contains
+                a pointer to an object that mysteriously failed to get marked.
+                Addr must be specified as a hexadecimal integer.

+See README.alpha for Linux on DEC AXP info.
+
+This file applies mostly to Linux/Intel IA32.  Ports to Linux on an M68K, IA64,
+SPARC, MIPS, Alpha and PowerPC are also integrated.  They should behave
+similarly, except that the PowerPC port lacks incremental GC support, and
+it is unknown to what extent the Linux threads code is functional.
+See below for M68K specific notes.
+
+Incremental GC is generally supported.
+
+Dynamic libraries are supported on an ELF system.  A static executable
+should be linked with the gcc option "-Wl,-defsym,_DYNAMIC=0".
+
+The collector appears to work reliably with Linux threads, but beware
+of older versions of glibc and gdb.
+
+The garbage collector uses SIGPWR and SIGXCPU if it is used with
+Linux threads.  These should not be touched by the client program.
+
+To use threads, you need to abide by the following requirements:
+
+1) You need to use LinuxThreads or NPTL (which are included in libc6).
+
+   The collector relies on some implementation details of the LinuxThreads
+   package.  This code may not work on other
+   pthread implementations (in particular it will *not* work with
+   MIT pthreads).
+
+2) You must compile the collector with -DGC_LINUX_THREADS (or
+   just -DGC_THREADS) and -D_REENTRANT specified in the Makefile.
+
+3a) Every file that makes thread calls should define GC_LINUX_THREADS and
+   _REENTRANT and then include gc.h.  Gc.h redefines some of the
+   pthread primitives as macros which also provide the collector with
+   information it requires.
+
+3b) A new alternative to (3a) is to build the collector and compile GC clients
+   with -DGC_USE_LD_WRAP, and to link the final program with
+
+   (for ld) --wrap dlopen --wrap pthread_create \
+            --wrap pthread_join --wrap pthread_detach \
+            --wrap pthread_sigmask --wrap pthread_exit --wrap pthread_cancel
+
+   (for gcc) -Wl,--wrap -Wl,dlopen -Wl,--wrap -Wl,pthread_create \
+             -Wl,--wrap -Wl,pthread_join -Wl,--wrap -Wl,pthread_detach \
+             -Wl,--wrap -Wl,pthread_sigmask -Wl,--wrap -Wl,pthread_exit \
+             -Wl,--wrap -Wl,pthread_cancel
+
+   In any case, _REENTRANT should be defined during compilation.
+
+4) Dlopen() disables collection during its execution.  (It can't run
+   concurrently with the collector, since the collector looks at its
+   data structures.  It can't acquire the allocator lock, since arbitrary
+   user startup code may run as part of dlopen().)  Under unusual
+   conditions, this may cause unexpected heap growth.
+
+5) The combination of GC_LINUX_THREADS, REDIRECT_MALLOC, and incremental
+   collection is probably not fully reliable, though it now seems to work
+   in simple cases.
+
+6) Thread local storage may not be viewed as part of the root set by the
+   collector.  This probably depends on the linuxthreads version.  For the
+   time being, any collectable memory referenced by thread local storage should
+   also be referenced from elsewhere, or be allocated as uncollectable.
+   (This is really a bug that should be fixed somehow.  The current GC
+   version probably gets things right if there are not too many tls locations
+   and if dlopen is not used.)

+M68K LINUX:
+(From Richard Zidlicky)

+The collector uses a large amount of conditional compilation in order to
+deal with platform dependencies.  This violates a number of known coding
+standards.  On the other hand, it seems to be the only practical way to
+support this many platforms without excessive code duplication.
+
+A few guidelines have mostly been followed in order to keep this manageable:
+
+1) #if and #ifdef directives are properly indented whenever easily possible.
+All known C compilers allow whitespace between the "#" and the "if" to make
+this possible.  ANSI C also allows white space before the "#", though we
+avoid that.  It has the known disadvantages that it differs from the normal
+GNU conventions, and that it makes patches larger than otherwise necessary.
+In my opinion, it's still well worth it, for the same reason that we indent
+ordinary "if" statements.
+
+2) Whenever possible, tests are performed on the macros defined in gcconfig.h
+instead of directly testing platform-specific predefined macros.  This makes
+it relatively easy to adapt to new compilers with a different set of
+predefined macros.  Currently these macros generally identify platforms
+instead of features.  In many cases, this is a mistake.
+
+Many of the tested configuration macros are at least somewhat defined in
+either include/private/gcconfig.h or in Makefile.direct.  Here is an attempt
+at documenting these macros:  (Thanks to Walter Bright for suggesting
+this.  This is a work in progress)
+
+MACRO           EXPLANATION
+-----           -----------
+
+GC_DEBUG        Tested by gc.h.  Causes all-upper-case macros to
+                expand to calls to debug versions of collector routines.
+
+GC_DEBUG_REPLACEMENT    Tested by gc.h. Causes GC_MALLOC/REALLOC() to be
+                defined as GC_debug_malloc/realloc_replacement().
+
+GC_NO_THREAD_REDIRECTS  Tested by gc.h.  Prevents redirection of thread
+                creation routines etc. to GC_ versions.  Requires the
+                programmer to explicitly handle thread registration.
+
+GC_NO_THREAD_DECLS      Tested by gc.h.  MS Windows only.  Do not declare
+                Windows thread creation routines and do not include windows.h.
+
+GC_UNDERSCORE_STDCALL   Tested by gc.h.  Explicitly prefix exported/imported
+                WINAPI (__stdcall) symbols with '_' (underscore).  Could be
+                used with MinGW (for x86) compiler (in conjunction with
+                GC_DLL) to follow MS conventions for __stdcall symbols naming.
+
+_ENABLE_ARRAYNEW
+                #define'd by the Digital Mars C++ compiler when
+                operator new[] and delete[] are separately
+                overloadable. Used in gc_cpp.h.
+
+_DLL            Tested by gc_config_macros.h. Defined by Visual C++ if runtime
+                dynamic libraries are in use.  Used (only if none of GC_DLL,
+                GC_NOT_DLL, __GNUC__ are defined) to test whether
+                __declspec(dllimport) needs to be added to declarations
+                to support the case in which the collector is in a DLL.
+
+GC_DLL          Defined by user if dynamic libraries are being built
+                or used.  Also set by gc.h if _DLL is defined (except for
+                mingw) while GC_NOT_DLL and __GNUC__ are both undefined.
+                This is the macro that is tested internally to determine
+                whether the GC is in its own dynamic library.  May need
+                to be set by clients before including gc.h.  Note that
+                inside the GC implementation it indicates that the
+                collector is in its own dynamic library, should export
+                its symbols, etc.  But in clients it indicates that the
+                GC resides in a different DLL, its entry points should
+                be referenced accordingly, and precautions may need to
+                be taken to properly deal with statically allocated
+                variables in the main program.  Used for MS Windows.
+                Also used by GCC v4+ (only when the dynamic shared library
+                is being built) to hide internally used symbols.
+
+GC_NOT_DLL      User-settable macro that overrides _DLL, e.g. if runtime
+                dynamic libraries are used, but the collector is in a static
+                library.  Tested by gc_config_macros.h.
+
+GC_REQUIRE_WCSDUP       Force GC to export GC_wcsdup() (the Unicode version
+                of GC_strdup); could be useful in the leak-finding mode.
+
+
+These define arguments influence the collector configuration:
+
+FIND_LEAK       Causes GC_find_leak to be initially set.  This causes the
+  collector to assume that all inaccessible objects should have been
+  explicitly deallocated, and reports exceptions.  Finalization and the test
+  program are not usable in this mode.
+
+GC_FINDLEAK_DELAY_FREE  Turns on deferred freeing of objects in the
+  leak-finding mode letting the collector to detect alter-object-after-free
+  errors as well as detect leaked objects sooner (instead of only when program
+  terminates).  Has no effect if SHORT_DBG_HDRS.
+
+GC_ABORT_ON_LEAK        Causes the application to be terminated once leaked or
+  smashed (corrupted on use-after-free) objects are found (after printing the
+  information about that objects).
+
+SUNOS5SIGS      Solaris-like signal handling.  This is probably misnamed,
+  since it really doesn't guarantee much more than POSIX.  Currently set only
+  for Solaris2.X, HPUX, and DRSNX.  Should probably be set for some other
+  platforms.
+
+PCR     Set if the collector is being built as part of the Xerox Portable
+  Common Runtime.
+
+USE_COMPILER_TLS  Assume the existence of __thread-style thread-local storage.
+  Set automatically for thread-local allocation with the HP/UX vendor
+  compiler.  Usable with gcc on sufficiently up-to-date ELF platforms.
+
+IMPORTANT: Any of the _THREADS options must normally also be defined in
+  the client before including gc.h.  This redefines thread primitives to
+  invoke the GC_ versions instead.  Alternatively, linker-based symbol
+  interception can be used on a few platforms.
+
+GC_THREADS      Should set the appropriate one of the below macros,
+  except GC_WIN32_PTHREADS, which must be set explicitly.  Tested by gc.h.
+
+GC_SOLARIS_THREADS      Enables support for Solaris pthreads.
+  Must also define _REENTRANT.
+
+GC_IRIX_THREADS         Enables support for Irix pthreads.  See README.sgi.
+
+GC_HPUX_THREADS         Enables support for HP/UX 11 pthreads.
+  Also requires _REENTRANT or _POSIX_C_SOURCE=199506L. See README.hp.
+
+GC_LINUX_THREADS        Enables support for Xavier Leroy's Linux threads
+  or NPTL threads. See README.linux.  _REENTRANT may also be required.
+
+GC_OSF1_THREADS         Enables support for Tru64 pthreads.
+
+GC_FREEBSD_THREADS      Enables support for FreeBSD pthreads.
+  Appeared to run into some underlying thread problems.
+
+GC_NETBSD_THREADS       Enables support for NetBSD pthreads.
+
+GC_OPENBSD_THREADS      Enables support for OpenBSD pthreads.
+
+GC_DARWIN_THREADS       Enables support for Mac OS X pthreads.
+
+GC_AIX_THREADS  Enables support for IBM AIX threads.
+
+GC_DGUX386_THREADS      Enables support for DB/UX on I386 threads.
+  See README.DGUX386.  (Probably has not been tested recently.)
+
+GC_WIN32_THREADS        Enables support for Win32 threads.  That makes sense
+  for this Makefile only under Cygwin.
+
+GC_WIN32_PTHREADS       Enables support for Ming32 pthreads.  This cannot be
+  enabled automatically by GC_THREADS, which would assume Win32 native
+  threads.
+
+PTW32_STATIC_LIB        Causes the static version of the Mingw pthreads
+  library to be used.  Requires GC_WIN32_PTHREADS.
+
+GC_PTHREADS_PARAMARK    Causes pthread-based parallel mark implementation
+  to be used even if GC_WIN32_PTHREADS is undefined.  (Useful for WinCE.)
+
+ALL_INTERIOR_POINTERS   Allows all pointers to the interior of objects to be
+  recognized.  (See gc_priv.h for consequences.)  Alternatively,
+  GC_all_interior_pointers can be set at process initialization time.
+
+SMALL_CONFIG    Tries to tune the collector for small heap sizes,
+  usually causing it to use less space in such situations.  Incremental
+  collection no longer works in this case.  Also, removes some
+  statistic-printing code.  Turns off some optimization algorithms (like data
+  prefetching in the mark routine).
+
+GC_DISABLE_INCREMENTAL  Turn off the incremental collection support.
+
+NO_INCREMENTAL  Causes the gctest program to not invoke the incremental
+  collector.  This has no impact on the generated library, only on the test
+  program.  (This is often useful for debugging failures unrelated to
+  incremental GC.)
+
+LARGE_CONFIG    Tunes the collector for unusually large heaps.
+  Necessary for heaps larger than about 4 GiB on most (64-bit) machines.
+  Recommended for heaps larger than about 500 MiB.  Not recommended for
+  embedded systems.  Could be used in conjunction with SMALL_CONFIG to
+  generate smaller code (by disabling incremental collection support,
+  statistic printing and some optimization algorithms).
+
+DONT_ADD_BYTE_AT_END    Meaningful only with ALL_INTERIOR_POINTERS or
+  GC_all_interior_pointers = 1.  Normally ALL_INTERIOR_POINTERS
+  causes all objects to be padded so that pointers just past the end of
+  an object can be recognized.  This can be expensive.  (The padding
+  is normally more than one byte due to alignment constraints.)
+  DONT_ADD_BYTE_AT_END disables the padding.
+
+NO_EXECUTE_PERMISSION   May cause some or all of the heap to not
+  have execute permission, i.e. it may be impossible to execute
+  code from the heap.  Currently this only affects the incremental
+  collector on UNIX machines.  It may greatly improve its performance,
+  since this may avoid some expensive cache synchronization.  Alternatively,
+  GC_set_pages_executable can be called at the process initialization time.
+
+GC_NO_OPERATOR_NEW_ARRAY        Declares that the C++ compiler does not
+  support the  new syntax "operator new[]" for allocating and deleting arrays.
+  See gc_cpp.h for details.  No effect on the C part of the collector.
+  This is defined implicitly in a few environments.  Must also be defined
+  by clients that use gc_cpp.h.
+
+REDIRECT_MALLOC=<X>     Causes malloc to be defined as alias for X.
+  Unless the following macros are defined, realloc is also redirected
+  to GC_realloc, and free is redirected to GC_free.
+  Calloc and str[n]dup are redefined in terms of the new malloc.  X should
+  be either GC_malloc or GC_malloc_uncollectable, or
+  GC_debug_malloc_replacement.  (The latter invokes GC_debug_malloc
+  with dummy source location information, but still results in
+  properly remembered call stacks on Linux/X86 and Solaris/SPARC.
+  It requires that the following two macros also be used.)
+  The former is occasionally useful for working around leaks in code
+  you don't want to (or can't) look at.  It may not work for
+  existing code, but it often does.  Neither works on all platforms,
+  since some ports use malloc or calloc to obtain system memory.
+  (Probably works for UNIX, and Win32.)  If you build with DBG_HDRS_ALL,
+  you should only use GC_debug_malloc_replacement as a malloc
+  replacement.
+
+REDIRECT_REALLOC=<X>    Causes GC_realloc to be redirected to X.
+  The canonical use is REDIRECT_REALLOC=GC_debug_realloc_replacement,
+  together with REDIRECT_MALLOC=GC_debug_malloc_replacement to
+  generate leak reports with call stacks for both malloc and realloc.
+  This also requires REDIRECT_FREE.
+
+REDIRECT_FREE=<X>       Causes free to be redirected to X.  The canonical use
+  is REDIRECT_FREE=GC_debug_free.
+
+IGNORE_FREE     Turns calls to free into a no-op.  Only useful with
+  REDIRECT_MALLOC.
+
+NO_DEBUGGING    Removes GC_dump and the debugging routines it calls.
+  Reduces code size slightly at the expense of debuggability.
+
+DEBUG_THREADS   Turn on printing additional thread-support debugging
+  information.
+
+JAVA_FINALIZATION       Makes it somewhat safer to finalize objects out of
+  order by specifying a nonstandard finalization mark procedure  (see
+  finalize.c).  Objects reachable from finalizable objects will be marked
+  in a separate post-pass, and hence their memory won't be reclaimed.
+  Not recommended unless you are implementing a language that specifies
+  these semantics.  Since 5.0, determines only the initial value
+  of GC_java_finalization variable.
+
+FINALIZE_ON_DEMAND      Causes finalizers to be run only in response
+  to explicit GC_invoke_finalizers() calls.
+  In 5.0 this became runtime adjustable, and this only determines the
+  initial value of GC_finalize_on_demand.
+
+ATOMIC_UNCOLLECTABLE    Includes code for GC_malloc_atomic_uncollectable.
+  This is useful if either the vendor malloc implementation is poor,
+  or if REDIRECT_MALLOC is used.
+
+MARK_BIT_PER_GRANULE    Requests that a mark bit (or often byte)
+  be allocated for each allocation granule, as opposed to each object.
+  This often improves speed, possibly at some cost in space and/or
+  cache footprint.  Normally it is best to let this decision be
+  made automatically depending on platform.
+
+MARK_BIT_PER_OBJ        Requests that a mark bit be allocated for each
+  object instead of allocation granule.  The opposite of
+  MARK_BIT_PER_GRANULE.
+
+HBLKSIZE=<ddd>  Explicitly sets the heap block size (where ddd is a power of
+  2 between 512 and 16384).  Each heap block is devoted to a single size and
+  kind of object.  For the incremental collector it makes sense to match
+  the most likely page size.  Otherwise large values result in more
+  fragmentation, but generally better performance for large heaps.
+
+USE_MMAP        Use MMAP instead of sbrk to get new memory.
+  Works for Linux, FreeBSD, Cygwin, Solaris and Irix.
+
+USE_MUNMAP      Causes memory to be returned to the OS under the right
+  circumstances.  This currently disables VM-based incremental collection
+  (except for Win32 with GetWriteWatch() available).
+  Works under some Unix, Linux and Windows versions.
+  Requires USE_MMAP except for Windows.
+
+MUNMAP_THRESHOLD=<value>        Set the desired memory blocks unmapping
+  threshold (the number of sequential garbage collections for which
+  a candidate block for unmapping should remain free).
+
+GC_FORCE_UNMAP_ON_GCOLLECT      Set "unmap as much as possible on explicit GC"
+  mode on by default.  The mode could be changed at run-time.  Has no effect
+  unless unmapping is turned on.  Has no effect on implicitly-initiated
+  garbage collections.
+
+MMAP_STACKS (for Solaris threads)       Use mmap from /dev/zero rather than
+  GC_scratch_alloc() to get stack memory.
+
+PRINT_BLACK_LIST        Whenever a black list entry is added, i.e. whenever
+  the garbage collector detects a value that looks almost, but not quite,
+  like a pointer, print both the address containing the value, and the
+  value of the near-bogus-pointer.  Can be used to identify regions of
+  memory that are likely to contribute misidentified pointers.
+
+KEEP_BACK_PTRS  Add code to save back pointers in debugging headers
+  for objects allocated with the debugging allocator.  If all objects
+  through GC_MALLOC with GC_DEBUG defined, this allows the client
+  to determine how particular or randomly chosen objects are reachable
+  for debugging/profiling purposes.  The gc_backptr.h interface is
+  implemented only if this is defined.
+
+GC_ASSERTIONS   Enable some internal GC assertion checking.  Currently
+  this facility is only used in a few places.  It is intended primarily
+  for debugging of the garbage collector itself, but could also...
+
+DBG_HDRS_ALL    Make sure that all objects have debug headers.  Increases
+  the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging
+  code (especially KEEP_BACK_PTRS).  Makes SHORT_DBG_HDRS possible.
+  Assumes that all client allocation is done through debugging allocators.
+
+SHORT_DBG_HDRS  Assume that all objects have debug headers.  Shorten
+  the headers to minimize object size, at the expense of checking for
+  writes past the end of an object.  This is intended for environments
+  in which most client code is written in a "safe" language, such as
+  Scheme or Java.  Assumes that all client allocation is done using
+  the GC_debug_ functions, or through the macros that expand to these,
+  or by redirecting malloc to GC_debug_malloc_replacement.
+  (Also eliminates the field for the requested object size.)
+  Occasionally could be useful for debugging of client code.  Slows down the
+  collector somewhat, but not drastically.
+
+SAVE_CALL_COUNT=<n>     Set the number of call frames saved with objects
+  allocated through the debugging interface.  Affects the amount of
+  information generated in leak reports.  Only matters on platforms
+  on which we can quickly generate call stacks, currently Linux/(X86 & SPARC)
+  and Solaris/SPARC and platforms that provide execinfo.h.
+  Default is zero.  On X86, client
+  code should NOT be compiled with -fomit-frame-pointer.
+
+SAVE_CALL_NARGS=<n>     Set the number of functions arguments to be saved
+  with each call frame.  Default is zero.  Ignored if we don't know how to
+  retrieve arguments on the platform.
+
+CHECKSUMS       Reports on erroneously clear dirty bits, and unexpectedly
+  altered stubborn objects, at substantial performance cost.  Use only for
+  debugging of the incremental collector.  Not compatible with USE_MUNMAP
+  or threads.
+
+GC_GCJ_SUPPORT  Includes support for gcj (and possibly other systems
+  that include a pointer to a type descriptor in each allocated object).
+  Building this way requires an ANSI C compiler.
+
+USE_I686_PREFETCH       Causes the collector to issue Pentium III style
+  prefetch instructions.  No effect except on X86 Linux platforms.
+  Assumes a very recent gcc-compatible compiler and assembler.
+  (Gas prefetcht0 support was added around May 1999.)
+  Empirically the code appears to still run correctly on Pentium II
+  processors, though with no performance benefit.  May not run on other
+  X86 processors?  In some cases this improves performance by
+  15% or so.
+
+USE_3DNOW_PREFETCH      Causes the collector to issue AMD 3DNow style
+  prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
+  Minimally tested.  Didn't appear to be an obvious win on a K6-2/500.
+
+USE_PPC_PREFETCH        Causes the collector to issue PowerPC style
+  prefetch instructions.  No effect except on PowerPC OS X platforms.
+  Performance impact untested.
+
+GC_USE_LD_WRAP  In combination with the old flags listed in README.linux
+  causes the collector some system and pthread calls in a more transparent
+  fashion than the usual macro-based approach.  Requires GNU ld, and
+  currently probably works only with Linux.
+
+GC_USE_DLOPEN_WRAP      Causes the collector to redefine malloc and
+  intercepted pthread routines with their real names, and causes it to use
+  dlopen and dlsym to refer to the original versions.  This makes it possible
+  to build an LD_PRELOADable malloc replacement library.
+
+THREAD_LOCAL_ALLOC      Defines GC_malloc(), GC_malloc_atomic() and
+  GC_gcj_malloc() to use a per-thread set of free-lists. These then allocate
+  in a way that usually does not involve acquisition of a global lock.
+  Recommended for multiprocessors.  Requires explicit GC_INIT() call, unless
+  REDIRECT_MALLOC is defined and GC_malloc is used first.
+
+USE_COMPILER_TLS        Causes thread local allocation to use
+  the compiler-supported "__thread" thread-local variables.  This is the
+  default in HP/UX.  It may help performance on recent Linux installations.
+  (It failed for me on RedHat 8, but appears to work on RedHat 9.)
+
+PARALLEL_MARK   Allows the marker to run in multiple threads.  Recommended
+  for multiprocessors.
+
+DONT_USE_SIGNALANDWAIT (Win32 only)     Use an alternate implementation for
+  marker threads (if PARALLEL_MARK defined) synchronization routines based
+  on InterlockedExchange() (instead of AO_fetch_and_add()) and on multiple
+  event objects (one per each marker instead of that based on Win32
+  SignalObjectAndWait() using a single event object).  This is the default
+  for WinCE.
+
+GC_WINMAIN_REDIRECT (Win32 only)        Redirect (rename) an application
+  WinMain to GC_WinMain; implement the "real" WinMain which starts a new
+  thread to call GC_WinMain after initializing the GC.  Useful for WinCE.
+  Incompatible with GC_DLL.
+
+GC_REGISTER_MEM_PRIVATE (Win32 only)    Force to register MEM_PRIVATE R/W
+  sections as data roots.  Might be needed for some WinCE 6.0+ custom builds.
+  (May result in numerous "Data Abort" messages logged to WinCE debugging
+  console.)  Incompatible with GCC toolchains for WinCE.
+
+NO_GETENV       Prevents the collector from looking at environment variables.
+  These may otherwise alter its configuration, or turn off GC altogether.
+  I don't know of a reason to disable this, except possibly if the resulting
+  process runs as a privileged user.  (This is on by default for WinCE.)
+
+EMPTY_GETENV_RESULTS    Define to workaround a reputed Wine bug in getenv
+  (getenv() may return an empty string instead of NULL for a missing entry).
+
+GC_READ_ENV_FILE (Win32 only)   Read environment variables from the GC "env"
+  file (named as the program name plus ".gc.env" extension).  Useful for WinCE
+  targets (which have no getenv()).  In the file, every variable is specified
+  in a separate line and the format is as "<name>=<value>" (without spaces).
+  A comment line may start with any character except for the Latin letters,
+  the digits and the underscore ('_').  The file encoding is Latin-1.
+
+USE_GLOBAL_ALLOC (Win32 only)   Use GlobalAlloc() instead of VirtualAlloc()
+  to allocate the heap.  May be needed to work around a Windows NT/2000 issue.
+  Incompatible with USE_MUNMAP.  See README.win32 for details.
+
+MAKE_BACK_GRAPH         Enable GC_PRINT_BACK_HEIGHT environment variable.
+  See README.environment for details.  Experimental.  Limited platform
+  support.  Implies DBG_HDRS_ALL.  All allocation should be done using
+  the debug interface.
+
+GC_PRINT_BACK_HEIGHT    Permanently turn on back-height printing mode
+  (useful when NO_GETENV).  See the similar environment variable description
+  in README.environment.  Requires MAKE_BACK_GRAPH defined.
+
+STUBBORN_ALLOC  Allows allocation of "hard to change" objects, and thus
+  makes incremental collection easier.  Was enabled by default until 6.0.
+  Rarely used, to my knowledge.
+
+HANDLE_FORK (Unix and Cygwin only)      Attempt by default to make GC_malloc()
+  work in a child process fork()'ed from a multi-threaded parent.  Not fully
+  POSIX-compliant and could be disabled at runtime (before GC_INIT).
+
+TEST_WITH_SYSTEM_MALLOC         Causes gctest to allocate (and leak) large
+  chunks of memory with the standard system malloc.  This will cause the root
+  set and collected heap to grow significantly if malloc'ed memory is somehow
+  getting traced by the collector.  This has no impact on the generated
+  library; it only affects the test.
+
+POINTER_MASK=<0x...>    Causes candidate pointers to be AND'ed with the given
+  mask before being considered.  If either this or the following macro is
+  defined, it will be assumed that all pointers stored in the heap need to be
+  processed this way.  Stack and register pointers will be considered both
+  with and without processing.  These macros are normally needed only to
+  support systems that use high-order pointer tags.  EXPERIMENTAL.
+
+POINTER_SHIFT=<n>       Causes the collector to left shift candidate pointers
+  by the indicated amount before trying to interpret them.  Applied after
+  POINTER_MASK. EXPERIMENTAL.  See also the preceding macro.
+
+ENABLE_TRACE    Enables the GC_TRACE=addr environment setting to do its job.
+  By default this is not supported in order to keep the marker as fast as
+  possible.
+
+DARWIN_DONT_PARSE_STACK         Causes the Darwin port to discover thread
+  stack bounds in the same way as other pthread ports, without trying to
+  walk the frames on the stack.  This is recommended only as a fall-back for
+  applications that don't support proper stack unwinding.
+
+GC_NO_THREADS_DISCOVERY (Darwin and Win32+DLL only)     Exclude DllMain-based
+  (on Windows) and task-threads-based (on Darwin) thread registration support.
+
+GC_DISCOVER_TASK_THREADS (Darwin and Win32+DLL only)    Compile the collector
+  with the implicitly turned on task-threads-based (on Darwin) or
+  DllMain-based (on Windows) approach of threads registering.  Only for
+  compatibility and for the case when it is not possible to call
+  GC_use_threads_discovery() early (before other GC calls).
+
+USE_PROC_FOR_LIBRARIES  Causes the Linux collector to treat writable
+  memory mappings (as reported by /proc) as roots, if it doesn't have
+  other information about them.  It no longer traverses dynamic loader
+  data structures to find dynamic library static data.  This may be
+  required for applications that store pointers in mmapped segments without
+  informing the collector.  But it typically performs poorly, especially
+  since it will scan inactive but cached NPTL thread stacks completely.
+
+IGNORE_DYNAMIC_LOADING  Don't define DYNAMIC_LOADING even if supported by the
+  platform (that is, build the collector with disabled tracing of dynamic
+  library data roots).
+
+NO_PROC_STAT    Causes the collector to avoid relying on Linux
+  "/proc/self/stat".
+
+NO_GETCONTEXT   Causes the collector to not assume the existence of the
+  getcontext() function on linux-like platforms.  This currently happens
+  implicitly on Darwin, Hurd, or ARM or MIPS hardware.  It is explicitly
+  needed for some old versions of FreeBSD.
+
+STATIC=static   Causes various GC_ symbols that could logically be declared
+  static to be declared (this is the default if NO_DEBUGGING is specified).
+  Reduces the number of visible symbols (letting the optimizer do its work
+  better), which is probably cleaner, but may make some kinds of debugging
+  and profiling harder.
+
+GC_DLL  Build dynamic-link library (or dynamic shared object).  For Unix this
+  causes the exported symbols to have 'default' visibility (ignored unless
+  GCC v4+) and the internal ones to have 'hidden' visibility.
+
+DONT_USE_USER32_DLL (Win32 only)        Don't use "user32" DLL import library
+  (containing MessageBox() entry); useful for a static GC library.
+
+GC_PREFER_MPROTECT_VDB  Choose MPROTECT_VDB manually in case of multiple
+  virtual dirty bit strategies are implemented (at present useful on Win32 and
+  Solaris to force MPROTECT_VDB strategy instead of the default GWW_VDB or
+  PROC_VDB ones).
+
+GC_IGNORE_GCJ_INFO      Disable GCJ-style type information (useful for
+  debugging on WinCE).
+
+GC_PRINT_VERBOSE_STATS  Permanently turn on verbose logging (useful for
+  debugging and profiling on WinCE).
+
+GC_ONLY_LOG_TO_FILE     Don't redirect GC stdout and stderr to the log file
+  specified by GC_LOG_FILE environment variable.  Has effect only when the
+  variable is set (to anything other than "0").
+
+GC_DONT_EXPAND  Don't expand the heap unless explicitly requested or forced to.
+
+GC_USE_ENTIRE_HEAP      Causes the non-incremental collector to use the
+  entire heap before collecting.  This sometimes results in more large block
+  fragmentation, since very large blocks will tend to get broken up during
+  each GC cycle.  It is likely to result in a larger working set, but lower
+  collection frequencies, and hence fewer instructions executed in the
+  collector.  This macro controls only the default GC_use_entire_heap value.
+
+GC_INITIAL_HEAP_SIZE=<value>    Set the desired default initial heap size
+  in bytes.
+
+GC_FREE_SPACE_DIVISOR=<value>   Set alternate default GC_free_space_divisor
+  value.
+
+GC_TIME_LIMIT=<milliseconds>    Set alternate default GC_time_limit value
+  (setting this to GC_TIME_UNLIMITED will essentially disable incremental
+  collection while leaving generational collection enabled).
+
+GC_FULL_FREQ=<value>    Set alternate default number of partial collections
+  between full collections (matters only if incremental collection is on).
+
+NO_CANCEL_SAFE (Posix platforms with threads only)      Don't bother trying
+  to make the collector safe for thread cancellation; cancellation is not
+  used.  (Note that if cancellation is used anyway, threads may end up
+  getting cancelled in unexpected places.)  Even without this option,
+  PTHREAD_CANCEL_ASYNCHRONOUS is never safe with the collector.  (We could
+  argue about its safety without the collector.)
+
+UNICODE (Win32 only)    Use the Unicode variant ('W') of the Win32 API instead
+  of ANSI/ASCII one ('A').  Useful for WinCE.
+
+PLATFORM_ANDROID        Compile for Android NDK platform.
+
+SN_TARGET_PS3           Compile for Sony PS/3.
+
+USE_GET_STACKBASE_FOR_MAIN (Linux only)  Use pthread_attr_getstack() instead
+  of __libc_stack_end (or instead of any hard-coded value) for getting the
+  primordial thread stack base (useful if the client modifies the program's
+  address space).

+Performance of the incremental collector can be greatly enhanced with
+-DNO_EXECUTE_PERMISSION.
+
+The collector should run with all of the -32, -n32 and -64 ABIs.  Remember to
+define the AS macro in the Makefile to be "as -64", or "as -n32".
+
+If you use -DREDIRECT_MALLOC=GC_malloc with C++ code, your code should make
+at least one explicit call to malloc instead of new to ensure that the proper
+version of malloc is linked in.
+
+Sproc threads are not supported in this version, though there may exist other
+ports.
+
+Pthreads support is provided.  This requires that:
+
+1) You compile the collector with -DGC_IRIX_THREADS specified in the Makefile.
+
+2) You have the latest pthreads patches installed.  
+
+(Though the collector makes only documented pthread calls,
+it relies on signal/threads interactions working just right in ways
+that are not required by the standard.  It is unlikely that this code
+will run on other pthreads platforms.  But please tell me if it does.)
+
+3) Every file that makes thread calls should define IRIX_THREADS and then
+include gc.h.  Gc.h redefines some of the pthread primitives as macros which
+also provide the collector with information it requires.
+
+4) pthread_cond_wait and pthread_cond_timed_wait should be prepared for
+premature wakeups.  (I believe the pthreads and realted standards require this
+anyway.  Irix pthreads often terminate a wait if a signal arrives.
+The garbage collector uses signals to stop threads.)
+
+5) It is expensive to stop a thread waiting in IO at the time the request is
+initiated.  Applications with many such threads may not exhibit acceptable
+performance with the collector.  (Increasing the heap size may help.)
+
+6) The collector should not be compiled with -DREDIRECT_MALLOC.  This
+confuses some library calls made by the pthreads implementation, which
+expect the standard malloc.

+The collector supports both incremental collection and threads under
+Solaris 2.  The incremental collector normally retrieves page dirty information
+through the appropriate /proc calls.  But it can also be configured
+(by defining MPROTECT_VDB instead of PROC_VDB in gcconfig.h) to use mprotect
+and signals.  This may result in shorter pause times, but it is no longer
+safe to issue arbitrary system calls that write to the heap.
+
+Under other UNIX versions,
+the collector normally obtains memory through sbrk.  There is some reason
+to expect that this is not safe if the client program also calls the system
+malloc, or especially realloc.  The sbrk man page strongly suggests this is
+not safe: "Many library routines use malloc() internally, so use brk()
+and sbrk() only when you know  that malloc() definitely will not be used by
+any library routine."  This doesn't make a lot of sense to me, since there
+seems to be no documentation as to which routines can transitively call malloc.
+Nonetheless, under Solaris2, the collector now allocates
+memory using mmap by default.  (It defines USE_MMAP in gcconfig.h.)
+You may want to reverse this decisions if you use -DREDIRECT_MALLOC=...
+
+Note:
+Before you run "make check", you need to set your LD_LIBRARY_PATH correctly
+(eg., to "/usr/local/lib") so that tests can find the shared library
+libgcc_s.so.1.  Alternatively, you can configure with --disable-shared.
+
+SOLARIS THREADS:
+
+Threads support is enabled by configure "--enable-threads=posix" option.
+(In case of GCC compiler, multi-threading support is on by default.)
+This causes the collector to be compiled with -D GC_THREADS (or
+-D GC_SOLARIS_THREADS) ensuring thread safety.
+This assumes use of the pthread_ interface.  Old style Solaris threads
+are no longer supported.
+Thread-local allocation is now on by default.  Parallel marking is on by
+default starting from GC v7.3 but it could be enabled or disabled manually
+by the corresponding "--enable/disable-parallel-mark" options.
+
+It is also essential that gc.h be included in files that call pthread_create,
+pthread_join, pthread_detach, or dlopen.  gc.h macro defines these to also do
+GC bookkeeping, etc.  gc.h must be included with one or both of these macros
+defined, otherwise these replacements are not visible.  A collector built in
+this way way only be used by programs that are linked with the threads library.
+
+Since 5.0 alpha5, dlopen disables collection temporarily,
+unless USE_PROC_FOR_LIBRARIES is defined.  In some unlikely cases, this
+can result in unpleasant heap growth.  But it seems better than the
+race/deadlock issues we had before.
+
+If threads are used on an X86 processor with malloc redirected to
+GC_malloc, it is necessary to call GC_INIT explicitly before forking the
+first thread.  (This avoids a deadlock arising from calling GC_thr_init
+with the allocation lock held.)
+
+It appears that there is a problem in using gc_cpp.h in conjunction with
+Solaris threads and Sun's C++ runtime.  Apparently the overloaded new operator
+is invoked by some iostream initialization code before threads are correctly
+initialized.  As a result, call to thr_self() in garbage collector
+initialization  SEGV faults.  Currently the only known workaround is to not
+invoke the garbage collector from a user defined global operator new, or to
+have it invoke the garbage-collector's allocators only after main has started.
+(Note that the latter requires a moderately expensive test in operator
+delete.)
+
+I encountered "symbol <unknown>: offet .... is non-aligned" errors.  These
+appear to be traceable to the use of the GNU assembler with the Sun linker.
+The former appears to generate a relocation not understood by the latter.
+The fix appears to be to use a consistent tool chain.  (As a non-Solaris-expert
+my solution involved hacking the libtool script, but I'm sure you can
+do something less ugly.)

+easily).  A toy editor (cord/de.exe) based on cords (heavyweight
+strings represented as trees) has been ported and is included.
+It runs fine under either win32 or win32S.  It serves as an example
+of a true Windows application, except that it was written by a
+nonexpert Windows programmer.  (There are some peculiarities
+in the way files are displayed.  The <cr> is displayed explicitly
+for standard DOS text files.  As in the UNIX version, control
+characters are displayed explicitly, but in this case as red text.
+This may be suboptimal for some tastes and/or sets of default

+To work around this problem, build the collector with -DUSE_GLOBAL_ALLOC.

+MinGW builds (including for x86_64) are available via cross-compilation, e.g.
+"./configure --host=i686-pc-mingw32; make check"
+
+To build the collector as a DLL, pass "--enable-shared --disable-static" to
+configure (this will instruct make compile with -D GC_DLL).
+
+Parallel marker could be enabled via "--enable-parallel-mark".
+
+Memory unmapping could be enabled via "--enable-munmap" (not well supported
+on Cygwin currently).
+
+Borland Tools
+-------------
+[Rarely tested.]
+For Borland tools, use BCC_MAKEFILE.  Note that
+Borland's compiler defaults to 1 byte alignment in structures (-a1),
+whereas Visual C++ appears to default to 8 byte alignment (/Zp8).
+The garbage collector in its default configuration EXPECTS AT
+LEAST 4 BYTE ALIGNMENT.  Thus the BORLAND DEFAULT MUST
+BE OVERRIDDEN.  (In my opinion, it should usually be anyway.
+I expect that -a1 introduces major performance penalties on a
+486 or Pentium.)  Note that this changes structure layouts.  (As a last
+resort, gcconfig.h can be changed to allow 1 byte alignment.  But
+this has significant negative performance implications.)
+The Makefile is set up to assume Borland 4.5.  If you have another
+version, change the line near the top.  By default, it does not
+require the assembler.  If you do have the assembler, I recommend
+removing the -DUSE_GENERIC.
+
+Digital Mars compiler
+---------------------
+
+Same as MS Visual C++ but might require
+-DAO_OLD_STYLE_INTERLOCKED_COMPARE_EXCHANGE option to compile with the
+parallel marker enabled.
+
+Watcom compiler
+---------------
+
+Ivan V. Demakov's README for the Watcom port:
+
+The collector has been compiled with Watcom C 10.6 and 11.0.
+It runs under win32, win32s, and even under msdos with dos4gw
+dos-extender. It should also run under OS/2, though this isn't
+tested. Under win32 the collector can be built either as dll
+or as static library.
+
+Note that all compilations were done under Windows 95 or NT.
+For unknown reason compiling under Windows 3.11 for NT (one
+attempt has been made) leads to broken executables.
+
+Incremental collection is not supported.
+
+cord is not ported.
+
+Before compiling you may need to edit WCC_MAKEFILE to set target
+platform, library type (dynamic or static), calling conventions, and
+optimization options.
+
+To compile the collector and testing programs use the command:
+    wmake -f WCC_MAKEFILE
+
+All programs using gc should be compiled with 4-byte alignment.
+For further explanations on this see comments about Borland.
+
+If the gc is compiled as dll, the macro ``GC_DLL'' should be defined before
+including "gc.h" (for example, with -DGC_DLL compiler option). It's
+important, otherwise resulting programs will not run.
+
+Ivan Demakov (email: ivan@tgrad.nsk.su)
+
+Note from Ivan Maidanski:
+
+Special note for OpenWatcom users: the C (unlike the C++) compiler (of the
+latest stable release, not sure for older ones) doesn't force pointer global
+variables (i.e. not struct fields, not sure for locals) to be aligned unless
+optimizing for speed (eg. "-ot" option is set); the "-zp" option (or align
+pragma) only controls alignment for structs; I don't know whether it's a bug or
+a feature (see an old report of same kind -
+http://bugzilla.openwatcom.org/show_bug.cgi?id=664), so You are warned.
+
+
+Incremental Collection
+----------------------
+There is some support for incremental collection.  By default, the
+collector chooses between explicit page protection, and GetWriteWatch-based
+write tracking automatically, depending on the platform.
+
+The former is slow and interacts poorly with a debugger.
+Pages are protected.  Protection faults are caught by a handler
+installed at the bottom of the handler
+stack.  Whenever possible, I recommend adding a call to
+GC_enable_incremental at the last possible moment, after most
+debugging is complete.  No system
+calls are wrapped by the collector itself.  It may be necessary
+to wrap ReadFile calls that use a buffer in the heap, so that the
+call does not encounter a protection fault while it's running.
+(As usual, none of this is an issue unless GC_enable_incremental
+is called.)
+
+Note that incremental collection is disabled with -DSMALL_CONFIG.
+
+Threads
+-------
+
+This version of the collector by default handles threads similarly
+to other platforms.  James Clark's code which tracks threads attached
+to the collector DLL still exists, but requires that both
+- the collector is built in a DLL with GC_DLL defined, and
+- GC_use_threads_discovery() is called before GC initialization, which
+  in turn must happen before creating additional threads.
+We generally recommend avoiding this if possible, since it seems to
+be less than 100% reliable.
+
+Use gc.mak (a.k.a NT_THREADS_MAKEFILE) instead of NT_MAKEFILE
+to build a version that supports both kinds of thread tracking.
+To build the garbage collector
+test with VC++ from the command line, use
+
+nmake /F ".\gc.mak" CFG="gctest - Win32 Release"
+
+This requires that the subdirectory gctest\Release exist.
+The test program and DLL will reside in the Release directory.
+
+This version currently supports incremental collection only if it is
+enabled before any additional threads are created.
+
+Since 6.3alpha2, threads are also better supported in static library builds
+with Microsoft tools (use NT_STATIC_THREADS_MAKEFILE) and with the GNU
+tools.  The collector must be built with GC_THREADS defined.
+(NT_STATIC_THREADS_MAKEFILE does this implicitly.  Under Cygwin,
+./configure --enable-threads=posix should be used.)
+
+For the normal, non-dll-based thread tracking to work properly,
+threads should be created with GC_CreateThread or GC_beginthreadex,
+and exit normally or call GC_endthreadex or GC_ExitThread.  (For
+Cygwin, use standard pthread calls instead.)  As in the pthread
+case, including gc.h will redefine CreateThread, _beginthreadex,
+_endthreadex, and ExitThread to call the GC_ versions instead.
+
+Note that, as usual, GC_CreateThread tends to introduce resource leaks
+that are avoided by GC_beginthreadex.  There is currently no equivalent of
+_beginthread, and it should not be used.
+
+GC_INIT should be called from the main executable before other GC calls.
+
+We strongly advise against using the TerminateThread() win32 API call,
+especially with the garbage collector.  Any use is likely to provoke a
+crash in the GC, since it makes it impossible for the collector to
+correctly track threads.
+
+To build the collector for Mingw32 Pthreads, use Makefile.direct and
+explicitly set GC_WIN32_PTHREADS.  Use -DPTW32_STATIC_LIB for the static
+threads library.

+<TITLE>Debugging Garbage Collector Related Problems</title>
+</head>
+<BODY>
+<H1>Debugging Garbage Collector Related Problems</h1>
+This page contains some hints on
+debugging issues specific to
+the Boehm-Demers-Weiser conservative garbage collector.
+It applies both to debugging issues in client code that manifest themselves
+as collector misbehavior, and to debugging the collector itself.
+<P>
+If you suspect a bug in the collector itself, it is strongly recommended
+that you try the latest collector release, even if it is labelled as "alpha",
+before proceeding.
+<H2>Bus Errors and Segmentation Violations</h2>
+<P>
+If the fault occurred in GC_find_limit, or with incremental collection enabled,
+this is probably normal.  The collector installs handlers to take care of
+these.  You will not see these unless you are using a debugger.
+Your debugger <I>should</i> allow you to continue.
+It's often preferable to tell the debugger to ignore SIGBUS and SIGSEGV
+("<TT>handle SIGSEGV SIGBUS nostop noprint</tt>" in gdb,
+"<TT>ignore SIGSEGV SIGBUS</tt>" in most versions of dbx)
+and set a breakpoint in <TT>abort</tt>.
+The collector will call abort if the signal had another cause,
+and there was not other handler previously installed.
+<P>
+We recommend debugging without incremental collection if possible.
+(This applies directly to UNIX systems.
+Debugging with incremental collection under win32 is worse.  See README.win32.)
+<P>
+If the application generates an unhandled SIGSEGV or equivalent, it may
+often be easiest to set the environment variable GC_LOOP_ON_ABORT.  On many
+platforms, this will cause the collector to loop in a handler when the
+SIGSEGV is encountered (or when the collector aborts for some other reason),
+and a debugger can then be attached to the looping
+process.  This sidesteps common operating system problems related
+to incomplete core files for multithreaded applications, etc.
+<H2>Other Signals</h2>
+On most platforms, the multithreaded version of the collector needs one or
+two other signals for internal use by the collector in stopping threads.
+It is normally wise to tell the debugger to ignore these.  On Linux,
+the collector currently uses SIGPWR and SIGXCPU by default.
+<H2>Warning Messages About Needing to Allocate Blacklisted Blocks</h2>
+The garbage collector generates warning messages of the form
+<PRE>
+Needed to allocate blacklisted block at 0x...
+</pre>
+or
+<PRE>
+Repeated allocation of very large block ...
+</pre>
+when it needs to allocate a block at a location that it knows to be
+referenced by a false pointer.  These false pointers can be either permanent
+(<I>e.g.</i> a static integer variable that never changes) or temporary.
+In the latter case, the warning is largely spurious, and the block will
+eventually be reclaimed normally.
+In the former case, the program will still run correctly, but the block
+will never be reclaimed.  Unless the block is intended to be
+permanent, the warning indicates a memory leak.
+<OL>
+<LI>Ignore these warnings while you are using GC_DEBUG.  Some of the routines
+mentioned below don't have debugging equivalents.  (Alternatively, write
+the missing routines and send them to me.)
+<LI>Replace allocator calls that request large blocks with calls to
+<TT>GC_malloc_ignore_off_page</tt> or
+<TT>GC_malloc_atomic_ignore_off_page</tt>.  You may want to set a
+breakpoint in <TT>GC_default_warn_proc</tt> to help you identify such calls.
+Make sure that a pointer to somewhere near the beginning of the resulting block
+is maintained in a (preferably volatile) variable as long as
+the block is needed.
+<LI>
+If the large blocks are allocated with realloc, we suggest instead allocating
+them with something like the following.  Note that the realloc size increment
+should be fairly large (e.g. a factor of 3/2) for this to exhibit reasonable
+performance.  But we all know we should do that anyway.
+<PRE>
+void * big_realloc(void *p, size_t new_size)
+{
+    size_t old_size = GC_size(p);
+    void * result;
+    if (new_size &lt;= 10000) return(GC_realloc(p, new_size));
+    if (new_size &lt;= old_size) return(p);
+    result = GC_malloc_ignore_off_page(new_size);
+    if (result == 0) return(0);
+    memcpy(result,p,old_size);
+    GC_free(p);

+}
+</pre>
+
+<LI> In the unlikely case that even relatively small object
+(&lt;20KB) allocations are triggering these warnings, then your address
+space contains lots of "bogus pointers", i.e. values that appear to
+be pointers but aren't.  Usually this can be solved by using GC_malloc_atomic
+or the routines in gc_typed.h to allocate large pointer-free regions of bitmaps, etc.  Sometimes the problem can be solved with trivial changes of encoding
+in certain values.  It is possible, to identify the source of the bogus
+pointers by building the collector with <TT>-DPRINT_BLACK_LIST</tt>,
+which will cause it to print the "bogus pointers", along with their location.
+
+<LI> If you get only a fixed number of these warnings, you are probably only
+introducing a bounded leak by ignoring them.  If the data structures being
+allocated are intended to be permanent, then it is also safe to ignore them.
+The warnings can be turned off by calling GC_set_warn_proc with a procedure
+that ignores these warnings (e.g. by doing absolutely nothing).
+</ol>
+
+<H2>The Collector References a Bad Address in <TT>GC_malloc</tt></h2>
+
+This typically happens while the collector is trying to remove an entry from
+its free list, and the free list pointer is bad because the free list link
+in the last allocated object was bad.
+<P>
+With &gt; 99% probability, you wrote past the end of an allocated object.
+Try setting <TT>GC_DEBUG</tt> before including <TT>gc.h</tt> and
+allocating with <TT>GC_MALLOC</tt>.  This will try to detect such
+overwrite errors.
+
+<H2>Unexpectedly Large Heap</h2>
+
+Unexpected heap growth can be due to one of the following:
+<OL>
+<LI> Data structures that are being unintentionally retained.  This
+is commonly caused by data structures that are no longer being used,
+but were not cleared, or by caches growing without bounds.
+<LI> Pointer misidentification.  The garbage collector is interpreting
+integers or other data as pointers and retaining the "referenced"
+objects.  A common symptom is that GC_dump() shows much of the heap
+as black-listed.
+<LI> Heap fragmentation.  This should never result in unbounded growth,
+but it may account for larger heaps.  This is most commonly caused
+by allocation of large objects.  On some platforms it can be reduced
+by building with -DUSE_MUNMAP, which will cause the collector to unmap
+memory corresponding to pages that have not been recently used.
+<LI> Per object overhead.  This is usually a relatively minor effect, but
+it may be worth considering.  If the collector recognizes interior
+pointers, object sizes are increased, so that one-past-the-end pointers
+are correctly recognized.  The collector can be configured not to do this
+(<TT>-DDONT_ADD_BYTE_AT_END</tt>).
+<P>
+The collector rounds up object sizes so the result fits well into the
+chunk size (<TT>HBLKSIZE</tt>, normally 4K on 32 bit machines, 8K
+on 64 bit machines) used by the collector.   Thus it may be worth avoiding
+objects of size 2K + 1 (or 2K if a byte is being added at the end.)
+</ol>
+The last two cases can often be identified by looking at the output
+of a call to <TT>GC_dump()</tt>.  Among other things, it will print the
+list of free heap blocks, and a very brief description of all chunks in
+the heap, the object sizes they correspond to, and how many live objects
+were found in the chunk at the last collection.
+<P>
+Growing data structures can usually be identified by
+<OL>
+<LI> Building the collector with <TT>-DKEEP_BACK_PTRS</tt>,
+<LI> Preferably using debugging allocation (defining <TT>GC_DEBUG</tt>
+before including <TT>gc.h</tt> and allocating with <TT>GC_MALLOC</tt>),
+so that objects will be identified by their allocation site,
+<LI> Running the application long enough so
+that most of the heap is composed of "leaked" memory, and
+<LI> Then calling <TT>GC_generate_random_backtrace()</tt> from backptr.h
+a few times to determine why some randomly sampled objects in the heap are
+being retained.
+</ol>
+<P>
+The same technique can often be used to identify problems with false
+pointers, by noting whether the reference chains printed by
+<TT>GC_generate_random_backtrace()</tt> involve any misidentified pointers.
+An alternate technique is to build the collector with
+<TT>-DPRINT_BLACK_LIST</tt> which will cause it to report values that
+are almost, but not quite, look like heap pointers.  It is very likely that
+actual false pointers will come from similar sources.
+<P>
+In the unlikely case that false pointers are an issue, it can usually
+be resolved using one or more of the following techniques:
+<OL>
+<LI> Use <TT>GC_malloc_atomic</tt> for objects containing no pointers.
+This is especially important for large arrays containing compressed data,
+pseudo-random numbers, and the like.  It is also likely to improve GC
+performance, perhaps drastically so if the application is paging.
+<LI> If you allocate large objects containing only
+one or two pointers at the beginning, either try the typed allocation
+primitives is <TT>gc_typed.h</tt>, or separate out the pointerfree component.
+<LI> Consider using <TT>GC_malloc_ignore_off_page()</tt>
+to allocate large objects.  (See <TT>gc.h</tt> and above for details.
+Large means &gt; 100K in most environments.)
+<LI> If your heap size is larger than 100MB or so, build the collector with
+<TT>-DLARGE_CONFIG</tt>.
+This allows the collector to keep more precise black-list
+information.
+<LI> If you are using heaps close to, or larger than, a gigabyte on a 32-bit
+machine, you may want to consider moving to a platform with 64-bit pointers.
+This is very likely to resolve any false pointer issues.
+</ol>
+<H2>Prematurely Reclaimed Objects</h2>
+The usual symptom of this is a segmentation fault, or an obviously overwritten
+value in a heap object.  This should, of course, be impossible.  In practice,
+it may happen for reasons like the following:
+<OL>
+<LI> The collector did not intercept the creation of threads correctly in
+a multithreaded application, <I>e.g.</i> because the client called
+<TT>pthread_create</tt> without including <TT>gc.h</tt>, which redefines it.
+<LI> The last pointer to an object in the garbage collected heap was stored
+somewhere were the collector couldn't see it, <I>e.g.</i> in an
+object allocated with system <TT>malloc</tt>, in certain types of
+<TT>mmap</tt>ed files,
+or in some data structure visible only to the OS.  (On some platforms,
+thread-local storage is one of these.)
+<LI> The last pointer to an object was somehow disguised, <I>e.g.</i> by
+XORing it with another pointer.
+<LI> Incorrect use of <TT>GC_malloc_atomic</tt> or typed allocation.
+<LI> An incorrect <TT>GC_free</tt> call.
+<LI> The client program overwrote an internal garbage collector data structure.
+<LI> A garbage collector bug.
+<LI> (Empirically less likely than any of the above.) A compiler optimization
+that disguised the last pointer.
+</ol>
+The following relatively simple techniques should be tried first to narrow
+down the problem:
+<OL>
+<LI> If you are using the incremental collector try turning it off for
+debugging.
+<LI> If you are using shared libraries, try linking statically.  If that works,
+ensure that DYNAMIC_LOADING is defined on your platform.
+<LI> Try to reproduce the problem with fully debuggable unoptimized code.
+This will eliminate the last possibility, as well as making debugging easier.
+<LI> Try replacing any suspect typed allocation and <TT>GC_malloc_atomic</tt>
+calls with calls to <TT>GC_malloc</tt>.
+<LI> Try removing any GC_free calls (<I>e.g.</i> with a suitable
+<TT>#define</tt>).
+<LI> Rebuild the collector with <TT>-DGC_ASSERTIONS</tt>.
+<LI> If the following works on your platform (i.e. if gctest still works
+if you do this), try building the collector with
+<TT>-DREDIRECT_MALLOC=GC_malloc_uncollectable</tt>.  This will cause
+the collector to scan memory allocated with malloc.
+</ol>
+If all else fails, you will have to attack this with a debugger.
+Suggested steps:
+<OL>
+<LI> Call <TT>GC_dump()</tt> from the debugger around the time of the failure.  Verify
+that the collectors idea of the root set (i.e. static data regions which
+it should scan for pointers) looks plausible.  If not, i.e. if it doesn't
+include some static variables, report this as
+a collector bug.  Be sure to describe your platform precisely, since this sort
+of problem is nearly always very platform dependent.
+<LI> Especially if the failure is not deterministic, try to isolate it to
+a relatively small test case.
+<LI> Set a break point in <TT>GC_finish_collection</tt>.  This is a good
+point to examine what has been marked, i.e. found reachable, by the
+collector.
+<LI> If the failure is deterministic, run the process
+up to the last collection before the failure.
+Note that the variable <TT>GC_gc_no</tt> counts collections and can be used
+to set a conditional breakpoint in the right one.  It is incremented just
+before the call to GC_finish_collection.
+If object <TT>p</tt> was prematurely recycled, it may be helpful to
+look at <TT>*GC_find_header(p)</tt> at the failure point.
+The <TT>hb_last_reclaimed</tt> field will identify the collection number
+during which its block was last swept.
+<LI> Verify that the offending object still has its correct contents at
+this point.
+Then call <TT>GC_is_marked(p)</tt> from the debugger to verify that the
+object has not been marked, and is about to be reclaimed.  Note that
+<TT>GC_is_marked(p)</tt> expects the real address of an object (the
+address of the debug header if there is one), and thus it may
+be more appropriate to call <TT>GC_is_marked(GC_base(p))</tt>
+instead.
+<LI> Determine a path from a root, i.e. static variable, stack, or
+register variable,
+to the reclaimed object.  Call <TT>GC_is_marked(q)</tt> for each object
+<TT>q</tt> along the path, trying to locate the first unmarked object, say
+<TT>r</tt>.
+<LI> If <TT>r</tt> is pointed to by a static root,
+verify that the location
+pointing to it is part of the root set printed by <TT>GC_dump()</tt>.  If it
+is on the stack in the main (or only) thread, verify that
+<TT>GC_stackbottom</tt> is set correctly to the base of the stack.  If it is
+in another thread stack, check the collector's thread data structure
+(<TT>GC_thread[]</tt> on several platforms) to make sure that stack bounds
+are set correctly.
+<LI> If <TT>r</tt> is pointed to by heap object <TT>s</tt>, check that the
+collector's layout description for <TT>s</tt> is such that the pointer field
+will be scanned.  Call <TT>*GC_find_header(s)</tt> to look at the descriptor
+for the heap chunk.  The <TT>hb_descr</tt> field specifies the layout
+of objects in that chunk.  See gc_mark.h for the meaning of the descriptor.
+(If it's low order 2 bits are zero, then it is just the length of the
+object prefix to be scanned.  This form is always used for objects allocated
+with <TT>GC_malloc</tt> or <TT>GC_malloc_atomic</tt>.)
+<LI> If the failure is not deterministic, you may still be able to apply some
+of the above technique at the point of failure.  But remember that objects
+allocated since the last collection will not have been marked, even if the
+collector is functioning properly.  On some platforms, the collector
+can be configured to save call chains in objects for debugging.
+Enabling this feature will also cause it to save the call stack at the
+point of the last GC in GC_arrays._last_stack.
+<LI> When looking at GC internal data structures remember that a number
+of <TT>GC_</tt><I>xxx</i> variables are really macro defined to
+<TT>GC_arrays._</tt><I>xxx</i>, so that
+the collector can avoid scanning them.

+cc ... gc.a
+.LP
+.SH DESCRIPTION
+.I GC_malloc
+and
+.I GC_free
+are plug-in replacements for standard malloc and free.  However,
+.I
+GC_malloc
+will attempt to reclaim inaccessible space automatically by invoking a conservative garbage collector at appropriate points.  The collector traverses all data structures accessible by following pointers from the machines registers, stack(s), data, and bss segments.  Inaccessible structures will be reclaimed.  A machine word is considered to be a valid pointer if it is an address inside an object allocated by
+.I
+GC_malloc
+or friends.
+.LP
+In most cases it is preferable to call the macros GC_MALLOC, GC_FREE, etc.
+instead of calling GC_malloc and friends directly.  This allows debugging
+versions of the routines to be substituted by defining GC_DEBUG before
+including gc.h.
+.LP
+See the documentation in the include files gc_cpp.h and gc_allocator.h,
+as well as the gcinterface.html file in the distribution,
+for an alternate, C++ specific interface to the garbage collector.
+Note that C++ programs generally
+need to be careful to ensure that all allocated memory (whether via new,
+malloc, or STL allocators) that may point to garbage collected memory
+is either itself garbage collected, or at least traced by the collector.
+.LP
+Unlike the standard implementations of malloc,
+.I
+GC_malloc
+clears the newly allocated storage.
+.I
+GC_malloc_atomic
+does not.  Furthermore, it informs the collector that the resulting object will never contain any pointers, and should therefore not be scanned by the collector.
+.LP
+.I
+GC_free
+can be used to deallocate objects, but its use is optional, and generally discouraged.
+.I
+GC_realloc
+has the standard realloc semantics.  It preserves pointer-free-ness.
+.I
+GC_register_finalizer
+allows for registration of functions that are invoked when an object becomes inaccessible.
+.LP
+The garbage collector tries to avoid allocating memory at locations that already appear to be referenced before allocation.  (Such apparent ``pointers'' are usually large integers and the like that just happen to look like an address.)  This may make it hard to allocate very large objects.  An attempt to do so may generate a warning.
+.LP
+.I
+GC_malloc_ignore_off_page
+and
+.I
+GC_malloc_atomic_ignore_off_page
+inform the collector that the client code will always maintain a pointer to near the beginning of the object (within the first 512 bytes), and that pointers beyond that can be ignored by the collector.  This makes it much easier for the collector to place large objects.  These are recommended for large object allocation.  (Objects expected to be larger than about 100KBytes should be allocated this way.)
+.LP
+It is also possible to use the collector to find storage leaks in programs destined to be run with standard malloc/free.  The collector can be compiled for thread-safe operation.  Unlike standard malloc, it is safe to call malloc after a previous malloc call was interrupted by a signal, provided the original malloc call is not resumed.
+.LP
+The collector may, on rare occasion produce warning messages.  On UNIX machines these appear on stderr.  Warning messages can be filtered, redirected, or ignored with
+.I
+GC_set_warn_proc
+This is recommended for production code.  See gc.h for details.
+.LP
+Fully portable code should call
+.I
+GC_INIT
+from the main program before making any other GC calls.
+On most platforms this does nothing and the collector is initialized on first use.
+On a few platforms explicit initialization is necessary.  And it can never hurt. 
+.LP
+Debugging versions of many of the above routines are provided as macros.  Their names are identical to the above, but consist of all capital letters.  If GC_DEBUG is defined before gc.h is included, these routines do additional checking, and allow the leak detecting version of the collector to produce slightly more useful output.  Without GC_DEBUG defined, they behave exactly like the lower-case versions.
+.LP
+On some machines, collection will be performed incrementally after a call to
+.I
+GC_enable_incremental.
+This may temporarily write protect pages in the heap.  See the README file for more information on how this interacts with system calls that write to the heap.
+.LP
+Other facilities not discussed here include limited facilities to support incremental collection on machines without appropriate VM support, provisions for providing more explicit object layout information to the garbage collector, more direct support for ``weak'' pointers, support for ``abortable'' garbage collections during idle time, etc.

+<H1> Conservative GC Algorithmic Overview </h1>
+<P>
+This is a description of the algorithms and data structures used in our
+conservative garbage collector.  I expect the level of detail to increase
+with time.  For a survey of GC algorithms, see for example
+<A HREF="ftp://ftp.cs.utexas.edu/pub/garbage/gcsurvey.ps"> Paul Wilson's
+excellent paper</a>.  For an overview of the collector interface,
+see <A HREF="gcinterface.html">here</a>.
+<P>
+This description is targeted primarily at someone trying to understand the
+source code.  It specifically refers to variable and function names.
+It may also be useful for understanding the algorithms at a higher level.
+<P>
+The description here assumes that the collector is used in default mode.
+In particular, we assume that it used as a garbage collector, and not just
+a leak detector.  We initially assume that it is used in stop-the-world,
+non-incremental mode, though the presence of the incremental collector
+will be apparent in the design.
+We assume the default finalization model, but the code affected by that
+is very localized.
+<H2> Introduction </h2>
+The garbage collector uses a modified mark-sweep algorithm.  Conceptually
+it operates roughly in four phases, which are performed occasionally
+as part of a memory allocation:
+
+<OL>
+
+<LI>
+<I>Preparation</i> Each object has an associated mark bit.
+Clear all mark bits, indicating that all objects
+are potentially unreachable.
+
+<LI>
+<I>Mark phase</i> Marks all objects that can be reachable via chains of
+pointers from variables.  Often the collector has no real information
+about the location of pointer variables in the heap, so it
+views all static data areas, stacks and registers as potentially containing
+pointers.  Any bit patterns that represent addresses inside
+heap objects managed by the collector are viewed as pointers.
+Unless the client program has made heap object layout information
+available to the collector, any heap objects found to be reachable from
+variables are again scanned similarly.
+
+<LI>
+<I>Sweep phase</i> Scans the heap for inaccessible, and hence unmarked,
+objects, and returns them to an appropriate free list for reuse.  This is
+not really a separate phase; even in non incremental mode this is operation
+is usually performed on demand during an allocation that discovers an empty
+free list.  Thus the sweep phase is very unlikely to touch a page that
+would not have been touched shortly thereafter anyway.
+
+<LI>
+<I>Finalization phase</i> Unreachable objects which had been registered
+for finalization are enqueued for finalization outside the collector.
+
+</ol>
+
+<P>
+The remaining sections describe the memory allocation data structures,
+and then the last 3 collection phases in more detail. We conclude by
+outlining some of the additional features implemented in the collector.
+
+<H2>Allocation</h2>
+The collector includes its own memory allocator.  The allocator obtains
+memory from the system in a platform-dependent way.  Under UNIX, it
+uses either <TT>malloc</tt>, <TT>sbrk</tt>, or <TT>mmap</tt>.
+<P>
+Most static data used by the allocator, as well as that needed by the
+rest of the garbage collector is stored inside the
+<TT>_GC_arrays</tt> structure.
+This allows the garbage collector to easily ignore the collectors own
+data structures when it searches for root pointers.  Other allocator
+and collector internal data structures are allocated dynamically
+with <TT>GC_scratch_alloc</tt>. <TT>GC_scratch_alloc</tt> does not
+allow for deallocation, and is therefore used only for permanent data
+structures.
+<P>
+The allocator allocates objects of different <I>kinds</i>.
+Different kinds are handled somewhat differently by certain parts
+of the garbage collector.  Certain kinds are scanned for pointers,
+others are not.  Some may have per-object type descriptors that
+determine pointer locations.  Or a specific kind may correspond
+to one specific object layout.  Two built-in kinds are uncollectable.
+One (<TT>STUBBORN</tt>) is immutable without special precautions.
+In spite of that, it is very likely that most C clients of the
+collector currently
+use at most two kinds: <TT>NORMAL</tt> and <TT>PTRFREE</tt> objects.
+The <A HREF="http://gcc.gnu.org/java">gcj</a> runtime also makes
+heavy use of a kind (allocated with GC_gcj_malloc) that stores
+type information at a known offset in method tables.
+<P>
+The collector uses a two level allocator.  A large block is defined to
+be one larger than half of <TT>HBLKSIZE</tt>, which is a power of 2,
+typically on the order of the page size.
+<P>
+Large block sizes are rounded up to
+the next multiple of <TT>HBLKSIZE</tt> and then allocated by
+<TT>GC_allochblk</tt>.  Recent versions of the collector
+use an approximate best fit algorithm by keeping free lists for
+several large block sizes.
+The actual
+implementation of <TT>GC_allochblk</tt>
+is significantly complicated by black-listing issues
+(see below).
+<P>
+Small blocks are allocated in chunks of size <TT>HBLKSIZE</tt>.
+Each chunk is
+dedicated to only one object size and kind.
+<P>
+The allocator maintains
+separate free lists for each size and kind of object.
+Associated with each kind is an array of free list pointers,
+with entry <TT>freelist[</tt><I>i</i><TT>]</tt> pointing to
+a free list of size <I>i</i> objects.
+In recent versions of the
+collector, index <TT>i</tt> is expressed in granules, which are the
+minimum allocatable unit, typically 8 or 16 bytes.
+The free lists themselves are
+linked through the first word in each object (see <TT>obj_link()</tt>
+macro).
+<P>
+Once a large block is split for use in smaller objects, it can only
+be used for objects of that size, unless the collector discovers a completely
+empty chunk.  Completely empty chunks are restored to the appropriate
+large block free list.
+<P>
+In order to avoid allocating blocks for too many distinct object sizes,
+the collector normally does not directly allocate objects of every possible
+request size.  Instead request are rounded up to one of a smaller number
+of allocated sizes, for which free lists are maintained.  The exact
+allocated sizes are computed on demand, but subject to the constraint
+that they increase roughly in geometric progression.  Thus objects
+requested early in the execution are likely to be allocated with exactly
+the requested size, subject to alignment constraints.
+See <TT>GC_init_size_map</tt> for details.
+<P>
+The actual size rounding operation during small object allocation is
+implemented as a table lookup in <TT>GC_size_map</tt> which maps
+a requested allocation size in bytes to a number of granules.
+<P>
+Both collector initialization and computation of allocated sizes are
+handled carefully so that they do not slow down the small object fast
+allocation path.  An attempt to allocate before the collector is initialized,
+or before the appropriate <TT>GC_size_map</tt> entry is computed,
+will take the same path as an allocation attempt with an empty free list.
+This results in a call to the slow path code (<TT>GC_generic_malloc_inner</tt>)
+which performs the appropriate initialization checks.
+<P>
+In non-incremental mode, we make a decision about whether to garbage collect
+whenever an allocation would otherwise have failed with the current heap size.
+If the total amount of allocation since the last collection is less than
+the heap size divided by <TT>GC_free_space_divisor</tt>, we try to
+expand the heap.  Otherwise, we initiate a garbage collection.  This ensures
+that the amount of garbage collection work per allocated byte remains
+constant.
+<P>
+The above is in fact an oversimplification of the real heap expansion
+and GC triggering heuristic, which adjusts slightly for root size
+and certain kinds of
+fragmentation.  In particular:
+<UL>
+<LI> Programs with a large root set size and
+little live heap memory will expand the heap to amortize the cost of
+scanning the roots.  
+<LI> Versions 5.x of the collector actually collect more frequently in
+nonincremental mode.  The large block allocator usually refuses to split
+large heap blocks once the garbage collection threshold is
+reached.  This often has the effect of collecting well before the
+heap fills up, thus reducing fragmentation and working set size at the
+expense of GC time.  Versions 6.x choose an intermediate strategy depending
+on how much large object allocation has taken place in the past.
+(If the collector is configured to unmap unused pages, versions 6.x
+use the 5.x strategy.)
+<LI> In calculating the amount of allocation since the last collection we
+give partial credit for objects we expect to be explicitly deallocated.
+Even if all objects are explicitly managed, it is often desirable to collect
+on rare occasion, since that is our only mechanism for coalescing completely
+empty chunks.
+</ul>
+<P>
+It has been suggested that this should be adjusted so that we favor
+expansion if the resulting heap still fits into physical memory.
+In many cases, that would no doubt help.  But it is tricky to do this
+in a way that remains robust if multiple application are contending
+for a single pool of physical memory.
+
+<H2>Mark phase</h2>
+
+At each collection, the collector marks all objects that are
+possibly reachable from pointer variables.  Since it cannot generally
+tell where pointer variables are located, it scans the following
+<I>root segments</i> for pointers:
+<UL>
+<LI>The registers.  Depending on the architecture, this may be done using
+assembly code, or by calling a <TT>setjmp</tt>-like function which saves
+register contents on the stack.
+<LI>The stack(s).  In the case of a single-threaded application,
+on most platforms this
+is done by scanning the memory between (an approximation of) the current
+stack pointer and <TT>GC_stackbottom</tt>.  (For Itanium, the register stack
+scanned separately.)  The <TT>GC_stackbottom</tt> variable is set in
+a highly platform-specific way depending on the appropriate configuration
+information in <TT>gcconfig.h</tt>.  Note that the currently active
+stack needs to be scanned carefully, since callee-save registers of
+client code may appear inside collector stack frames, which may
+change during the mark process.  This is addressed by scanning
+some sections of the stack "eagerly", effectively capturing a snapshot
+at one point in time.
+<LI>Static data region(s).  In the simplest case, this is the region
+between <TT>DATASTART</tt> and <TT>DATAEND</tt>, as defined in
+<TT>gcconfig.h</tt>.  However, in most cases, this will also involve
+static data regions associated with dynamic libraries.  These are
+identified by the mostly platform-specific code in <TT>dyn_load.c</tt>.
+</ul> 
+The marker maintains an explicit stack of memory regions that are known
+to be accessible, but that have not yet been searched for contained pointers.
+Each stack entry contains the starting address of the block to be scanned,
+as well as a descriptor of the block.  If no layout information is
+available for the block, then the descriptor is simply a length.
+(For other possibilities, see <TT>gc_mark.h</tt>.)
+<P>
+At the beginning of the mark phase, all root segments
+(as described above) are pushed on the
+stack by <TT>GC_push_roots</tt>.  (Registers and eagerly processed
+stack sections are processed by pushing the referenced objects instead
+of the stack section itself.)  If <TT>ALL_INTERIOR_PTRS</tt> is not
+defined, then stack roots require special treatment.  In this case, the
+normal marking code ignores interior pointers, but <TT>GC_push_all_stack</tt>
+explicitly checks for interior pointers and pushes descriptors for target
+objects.
+<P>
+The marker is structured to allow incremental marking.
+Each call to <TT>GC_mark_some</tt> performs a small amount of
+work towards marking the heap.
+It maintains
+explicit state in the form of <TT>GC_mark_state</tt>, which
+identifies a particular sub-phase.  Some other pieces of state, most
+notably the mark stack, identify how much work remains to be done
+in each sub-phase.  The normal progression of mark states for
+a stop-the-world collection is:
+<OL>
+<LI> <TT>MS_INVALID</tt> indicating that there may be accessible unmarked
+objects.  In this case <TT>GC_objects_are_marked</tt> will simultaneously
+be false, so the mark state is advanced to
+<LI> <TT>MS_PUSH_UNCOLLECTABLE</tt> indicating that it suffices to push
+uncollectable objects, roots, and then mark everything reachable from them.
+<TT>Scan_ptr</tt> is advanced through the heap until all uncollectable
+objects are pushed, and objects reachable from them are marked.
+At that point, the next call to <TT>GC_mark_some</tt> calls
+<TT>GC_push_roots</tt> to push the roots.  It the advances the
+mark state to
+<LI> <TT>MS_ROOTS_PUSHED</tt> asserting that once the mark stack is
+empty, all reachable objects are marked.  Once in this state, we work
+only on emptying the mark stack.  Once this is completed, the state
+changes to
+<LI> <TT>MS_NONE</tt> indicating that reachable objects are marked.
+</ol>
+
+The core mark routine <TT>GC_mark_from</tt>, is called
+repeatedly by several of the sub-phases when the mark stack starts to fill
+up.  It is also called repeatedly in <TT>MS_ROOTS_PUSHED</tt> state
+to empty the mark stack.
+The routine is designed to only perform a limited amount of marking at
+each call, so that it can also be used by the incremental collector.
+It is fairly carefully tuned, since it usually consumes a large majority
+of the garbage collection time.
+<P>
+The fact that it perform a only a small amount of work per call also
+allows it to be used as the core routine of the parallel marker.  In that
+case it is normally invoked on thread-private mark stacks instead of the
+global mark stack.  More details can be found in
+<A HREF="scale.html">scale.html</a>
+<P>
+The marker correctly handles mark stack overflows.  Whenever the mark stack
+overflows, the mark state is reset to <TT>MS_INVALID</tt>.
+Since there are already marked objects in the heap,
+this eventually forces a complete
+scan of the heap, searching for pointers, during which any unmarked objects
+referenced by marked objects are again pushed on the mark stack.  This
+process is repeated until the mark phase completes without a stack overflow.
+Each time the stack overflows, an attempt is made to grow the mark stack.
+All pieces of the collector that push regions onto the mark stack have to be
+careful to ensure forward progress, even in case of repeated mark stack
+overflows.  Every mark attempt results in additional marked objects.
+<P>
+Each mark stack entry is processed by examining all candidate pointers
+in the range described by the entry.  If the region has no associated
+type information, then this typically requires that each 4-byte aligned
+quantity (8-byte aligned with 64-bit pointers) be considered a candidate
+pointer.
+<P>
+We determine whether a candidate pointer is actually the address of
+a heap block.  This is done in the following steps:
+<NL>
+<LI> The candidate pointer is checked against rough heap bounds.
+These heap bounds are maintained such that all actual heap objects
+fall between them.  In order to facilitate black-listing (see below)
+we also include address regions that the heap is likely to expand into.
+Most non-pointers fail this initial test.
+<LI> The candidate pointer is divided into two pieces; the most significant
+bits identify a <TT>HBLKSIZE</tt>-sized page in the address space, and
+the least significant bits specify an offset within that page.
+(A hardware page may actually consist of multiple such pages.
+HBLKSIZE is usually the page size divided by a small power of two.)
+<LI>
+The page address part of the candidate pointer is looked up in a
+<A HREF="tree.html">table</a>.
+Each table entry contains either 0, indicating that the page is not part
+of the garbage collected heap, a small integer <I>n</i>, indicating
+that the page is part of large object, starting at least <I>n</i> pages
+back, or a pointer to a descriptor for the page.  In the first case,
+the candidate pointer i not a true pointer and can be safely ignored.
+In the last two cases, we can obtain a descriptor for the page containing
+the beginning of the object.
+<LI>
+The starting address of the referenced object is computed.
+The page descriptor contains the size of the object(s)
+in that page, the object kind, and the necessary mark bits for those
+objects.  The size information can be used to map the candidate pointer
+to the object starting address.  To accelerate this process, the page header
+also contains a pointer to a precomputed map of page offsets to displacements
+from the beginning of an object.  The use of this map avoids a
+potentially slow integer remainder operation in computing the object
+start address.
+<LI>
+The mark bit for the target object is checked and set.  If the object
+was previously unmarked, the object is pushed on the mark stack.
+The descriptor is read from the page descriptor.  (This is computed
+from information <TT>GC_obj_kinds</tt> when the page is first allocated.)
+</nl>
+<P>
+At the end of the mark phase, mark bits for left-over free lists are cleared,
+in case a free list was accidentally marked due to a stray pointer.
+
+<H2>Sweep phase</h2>
+
+At the end of the mark phase, all blocks in the heap are examined.
+Unmarked large objects are immediately returned to the large object free list.
+Each small object page is checked to see if all mark bits are clear.
+If so, the entire page is returned to the large object free list.
+Small object pages containing some reachable object are queued for later
+sweeping, unless we determine that the page contains very little free
+space, in which case it is not examined further.
+<P>
+This initial sweep pass touches only block headers, not
+the blocks themselves.  Thus it does not require significant paging, even
+if large sections of the heap are not in physical memory.
+<P>
+Nonempty small object pages are swept when an allocation attempt
+encounters an empty free list for that object size and kind.
+Pages for the correct size and kind are repeatedly swept until at
+least one empty block is found.  Sweeping such a page involves
+scanning the mark bit array in the page header, and building a free
+list linked through the first words in the objects themselves.
+This does involve touching the appropriate data page, but in most cases
+it will be touched only just before it is used for allocation.
+Hence any paging is essentially unavoidable.
+<P>
+Except in the case of pointer-free objects, we maintain the invariant
+that any object in a small object free list is cleared (except possibly
+for the link field).  Thus it becomes the burden of the small object
+sweep routine to clear objects.  This has the advantage that we can
+easily recover from accidentally marking a free list, though that could
+also be handled by other means.  The collector currently spends a fair
+amount of time clearing objects, and this approach should probably be
+revisited.
+<P>
+In most configurations, we use specialized sweep routines to handle common
+small object sizes.  Since we allocate one mark bit per word, it becomes
+easier to examine the relevant mark bits if the object size divides
+the word length evenly.  We also suitably unroll the inner sweep loop
+in each case.  (It is conceivable that profile-based procedure cloning
+in the compiler could make this unnecessary and counterproductive.  I
+know of no existing compiler to which this applies.)
+<P>
+The sweeping of small object pages could be avoided completely at the expense
+of examining mark bits directly in the allocator.  This would probably
+be more expensive, since each allocation call would have to reload
+a large amount of state (e.g. next object address to be swept, position
+in mark bit table) before it could do its work.  The current scheme
+keeps the allocator simple and allows useful optimizations in the sweeper.
+
+<H2>Finalization</h2>
+Both <TT>GC_register_disappearing_link</tt> and
+<TT>GC_register_finalizer</tt> add the request to a corresponding hash
+table.  The hash table is allocated out of collected memory, but
+the reference to the finalizable object is hidden from the collector.
+Currently finalization requests are processed non-incrementally at the
+end of a mark cycle.  
+<P>
+The collector makes an initial pass over the table of finalizable objects,
+pushing the contents of unmarked objects onto the mark stack.
+After pushing each object, the marker is invoked to mark all objects
+reachable from it.  The object itself is not explicitly marked.
+This assures that objects on which a finalizer depends are neither
+collected nor finalized.
+<P>
+If in the process of marking from an object the
+object itself becomes marked, we have uncovered
+a cycle involving the object.  This usually results in a warning from the
+collector.  Such objects are not finalized, since it may be
+unsafe to do so.  See the more detailed
+<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/finalization.html"> discussion of finalization semantics</a>.
+<P>
+Any objects remaining unmarked at the end of this process are added to
+a queue of objects whose finalizers can be run.  Depending on collector
+configuration, finalizers are dequeued and run either implicitly during
+allocation calls, or explicitly in response to a user request.
+(Note that the former is unfortunately both the default and not generally safe.
+If finalizers perform synchronization, it may result in deadlocks.
+Nontrivial finalizers generally need to perform synchronization, and
+thus require a different collector configuration.)
+<P>
+The collector provides a mechanism for replacing the procedure that is
+used to mark through objects.  This is used both to provide support for
+Java-style unordered finalization, and to ignore certain kinds of cycles,
+<I>e.g.</i> those arising from C++ implementations of virtual inheritance.
+
+<H2>Generational Collection and Dirty Bits</h2>
+We basically use the concurrent and generational GC algorithm described in
+<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/papers/pldi91.ps.Z">"Mostly Parallel Garbage Collection"</a>,
+by Boehm, Demers, and Shenker.
+<P>
+The most significant modification is that
+the collector always starts running in the allocating thread.
+There is no separate garbage collector thread.  (If parallel GC is
+enabled, helper threads may also be woken up.)
+If an allocation attempt either requests a large object, or encounters
+an empty small object free list, and notices that there is a collection
+in progress, it immediately performs a small amount of marking work
+as described above.
+<P>
+This change was made both because we wanted to easily accommodate
+single-threaded environments, and because a separate GC thread requires
+very careful control over the scheduler to prevent the mutator from
+out-running the collector, and hence provoking unneeded heap growth.
+<P>
+In incremental mode, the heap is always expanded when we encounter
+insufficient space for an allocation.  Garbage collection is triggered
+whenever we notice that more than
+<TT>GC_heap_size</tt>/2 * <TT>GC_free_space_divisor</tt>
+bytes of allocation have taken place.
+After <TT>GC_full_freq</tt> minor collections a major collection
+is started.
+<P>
+All collections initially run uninterrupted until a predetermined
+amount of time (50 msecs by default) has expired.  If this allows
+the collection to complete entirely, we can avoid correcting
+for data structure modifications during the collection.  If it does
+not complete, we return control to the mutator, and perform small
+amounts of additional GC work during those later allocations that
+cannot be satisfied from small object free lists. When marking completes,
+the set of modified pages is retrieved, and we mark once again from
+marked objects on those pages, this time with the mutator stopped.
+<P>
+We keep track of modified pages using one of several distinct mechanisms:
+<OL>
+<LI>
+Through explicit mutator cooperation.  Currently this requires
+the use of <TT>GC_malloc_stubborn</tt>, and is rarely used.
+<LI>
+(<TT>MPROTECT_VDB</tt>) By write-protecting physical pages and
+catching write faults.  This is
+implemented for many Unix-like systems and for win32.  It is not possible
+in a few environments.
+<LI>
+(<TT>PROC_VDB</tt>) By retrieving dirty bit information from /proc.
+(Currently only Sun's
+Solaris supports this.  Though this is considerably cleaner, performance
+may actually be better with mprotect and signals.)
+<LI>
+(<TT>PCR_VDB</tt>) By relying on an external dirty bit implementation, in this
+case the one in Xerox PCR.
+<LI>
+(<TT>DEFAULT_VDB</tt>) By treating all pages as dirty.  This is the default if 
+none of the other techniques is known to be usable, and
+<TT>GC_malloc_stubborn</tt> is not used.  Practical only for testing, or if
+the vast majority of objects use <TT>GC_malloc_stubborn</tt>.
+</ol>
+
+<H2>Black-listing</h2>
+
+The collector implements <I>black-listing</i> of pages, as described
+in
+<A HREF="http://www.acm.org/pubs/citations/proceedings/pldi/155090/p197-boehm/">
+Boehm, ``Space Efficient Conservative Collection'', PLDI '93</a>, also available
+<A HREF="papers/pldi93.ps.Z">here</a>.
+<P>
+During the mark phase, the collector tracks ``near misses'', i.e. attempts
+to follow a ``pointer'' to just outside the garbage-collected heap, or
+to a currently unallocated page inside the heap.  Pages that have been
+the targets of such near misses are likely to be the targets of
+misidentified ``pointers'' in the future.  To minimize the future
+damage caused by such misidentifications they will be allocated only to
+small pointerfree objects. 
+<P>
+The collector understands two different kinds of black-listing.  A
+page may be black listed for interior pointer references
+(<TT>GC_add_to_black_list_stack</tt>), if it was the target of a near
+miss from a location that requires interior pointer recognition,
+<I>e.g.</i> the stack, or the heap if <TT>GC_all_interior_pointers</tt>
+is set.  In this case, we also avoid allocating large blocks that include
+this page.
+<P>
+If the near miss came from a source that did not require interior
+pointer recognition, it is black-listed with
+<TT>GC_add_to_black_list_normal</tt>.
+A page black-listed in this way may appear inside a large object,
+so long as it is not the first page of a large object.
+<P>
+The <TT>GC_allochblk</tt> routine respects black-listing when assigning
+a block to a particular object kind and size.  It occasionally
+drops (i.e. allocates and forgets) blocks that are completely black-listed
+in order to avoid excessively long large block free lists containing
+only unusable blocks.  This would otherwise become an issue
+if there is low demand for small pointerfree objects.
+
+<H2>Thread support</h2>
+We support several different threading models.  Unfortunately Pthreads,
+the only reasonably well standardized thread model, supports too narrow
+an interface for conservative garbage collection.  There appears to be
+no completely portable way to allow the collector
+to coexist with various Pthreads
+implementations.  Hence we currently support only the more
+common Pthreads implementations.
+<P>
+In particular, it is very difficult for the collector to stop all other
+threads in the system and examine the register contents.  This is currently
+accomplished with very different mechanisms for some Pthreads
+implementations.  The Solaris implementation temporarily disables much
+of the user-level threads implementation by stopping kernel-level threads
+("lwp"s).  The Linux/HPUX/OSF1 and Irix implementations sends signals to
+individual Pthreads and has them wait in the signal handler.
+<P>
+The Linux and Irix implementations use
+only documented Pthreads calls, but rely on extensions to their semantics.
+The Linux implementation <TT>linux_threads.c</tt> relies on only very
+mild extensions to the pthreads semantics, and already supports a large number
+of other Unix-like pthreads implementations.  Our goal is to make this the
+only pthread support in the collector.
+<P>
+(The Irix implementation is separate only for historical reasons and should
+clearly be merged.  The current Solaris implementation probably performs
+better in the uniprocessor case, but does not support thread operations in the
+collector.  Hence it cannot support the parallel marker.)
+<P>
+All implementations must
+intercept thread creation and a few other thread-specific calls to allow
+enumeration of threads and location of thread stacks.  This is current
+accomplished with <TT># define</tt>'s in <TT>gc.h</tt>
+(really <TT>gc_pthread_redirects.h</tt>), or optionally
+by using ld's function call wrapping mechanism under Linux.
+<P>
+Recent versions of the collector support several facilities to enhance
+the processor-scalability and thread performance of the collector.
+These are discussed in more detail <A HREF="scale.html">here</a>.
+We briefly outline the data approach to thread-local allocation in the
+next section.
+<H2>Thread-local allocation</h2>
+If thread-local allocation is enabled, the collector keeps separate
+arrays of free lists for each thread.  Thread-local allocation
+is currently only supported on a few platforms.
+<P>
+The free list arrays associated
+with each thread are only used to satisfy requests for objects that
+are  both very small, and belong to one of a small number of well-known
+kinds.  These currently include "normal" and pointer-free objects.
+Depending on the configuration, "gcj" objects may also be included.
+<P>
+Thread-local free list entries contain either a pointer to the first
+element of a free list, or they contain a counter of the number of
+allocation granules, corresponding to objects of this size,
+allocated so far.  Initially they contain the
+value one, i.e. a small counter value.
+<P>
+Thread-local allocation allocates directly through the global
+allocator, if the object is of a size or kind not covered by the
+local free lists.
+<P>
+If there is an appropriate local free list, the allocator checks whether it
+contains a sufficiently small counter value.  If so, the counter is simply
+incremented by the counter value, and the global allocator is used.
+In this way, the initial few allocations of a given size bypass the local
+allocator.  A thread that only allocates a handful of objects of a given
+size will not build up its own free list for that size.  This avoids
+wasting space for unpopular objects sizes or kinds.
+<P>
+Once the counter passes a threshold, <TT>GC_malloc_many</tt> is called
+to allocate roughly <TT>HBLKSIZE</tt> space and put it on the corresponding
+local free list.  Further allocations of that size and kind then use
+this free list, and no longer need to acquire the allocation lock.
+The allocation procedure is otherwise similar to the global free lists.
+The local free lists are also linked using the first word in the object.
+In most cases this means they require considerably less time.
+<P>
+Local free lists are treated buy most of the rest of the collector
+as though they were in-use reachable data.  This requires some care,
+since pointer-free objects are not normally traced, and hence a special
+tracing procedure is required to mark all objects on pointer-free and
+gcj local free lists.
+<P>
+On thread exit, any remaining thread-local free list entries are
+transferred back to the global free list.
+<P>
+Note that if the collector is configured for thread-local allocation,
+GC versions before 7 do not invoke the thread-local allocator by default.
+<TT>GC_malloc</tt> only uses thread-local allocation in version 7 and later.

+<TITLE>Garbage Collector Interface</TITLE>
+</HEAD>
+<BODY>
+<H1>C Interface</h1>
+On many platforms, a single-threaded garbage collector library can be built
+to act as a plug-in malloc replacement.
+(Build with <TT>-DREDIRECT_MALLOC=GC_malloc -DIGNORE_FREE</tt>.)
+This is often the best way to deal with third-party libraries
+which leak or prematurely free objects.
+<TT>-DREDIRECT_MALLOC=GC_malloc</tt> is intended
+primarily as an easy way to adapt old code, not for new development.
+<P>
+New code should use the interface discussed below.
+<P>
+Code must be linked against the GC library.  On most UNIX platforms,
+depending on how the collector is built, this will be <TT>gc.a</tt>
+or <TT>libgc.{a,so}</tt>.
+<P>
+The following describes the standard C interface to the garbage collector.
+It is not a complete definition of the interface.  It describes only the
+most commonly used functionality, approximately in decreasing order of
+frequency of use.
+The full interface is described in
+<A HREF="http://hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gch.txt">gc.h</a>
+or <TT>gc.h</tt> in the distribution.
+<P>
+Clients should include <TT>gc.h</tt>.
+<P>
+In the case of multithreaded code,
+<TT>gc.h</tt> should be included after the threads header file, and
+after defining the appropriate <TT>GC_</tt><I>XXXX</i><TT>_THREADS</tt> macro.
+(For 6.2alpha4 and later, simply defining <TT>GC_THREADS</tt> should suffice.)
+The header file <TT>gc.h</tt> must be included
+in files that use either GC or threads primitives, since threads primitives
+will be redefined to cooperate with the GC on many platforms.
+<P>
+Thread users should also be aware that on many platforms objects reachable
+only from thread-local variables may be prematurely reclaimed.
+Thus objects pointed to by thread-local variables should also be pointed to
+by a globally visible data structure.  (This is viewed as a bug, but as
+one that is exceedingly hard to fix without some libc hooks.)
+<DL>
+<DT> <B>void * GC_MALLOC(size_t <I>nbytes</i>)</b>
+<DD>
+Allocates and clears <I>nbytes</i> of storage.
+Requires (amortized) time proportional to <I>nbytes</i>.
+The resulting object will be automatically deallocated when unreferenced.
+References from objects allocated with the system malloc are usually not
+considered by the collector.  (See <TT>GC_MALLOC_UNCOLLECTABLE</tt>, however.
+Building the collector with <TT>-DREDIRECT_MALLOC=GC_malloc_uncollectable
+is often a way around this.)
+<TT>GC_MALLOC</tt> is a macro which invokes <TT>GC_malloc</tt> by default or,
+if <TT>GC_DEBUG</tt>
+is defined before <TT>gc.h</tt> is included, a debugging version that checks
+occasionally for overwrite errors, and the like.
+<DT> <B>void * GC_MALLOC_ATOMIC(size_t <I>nbytes</i>)</b>
+<DD>
+Allocates <I>nbytes</i> of storage.
+Requires (amortized) time proportional to <I>nbytes</i>.
+The resulting object will be automatically deallocated when unreferenced.
+The client promises that the resulting object will never contain any pointers.
+The memory is not cleared.
+This is the preferred way to allocate strings, floating point arrays,
+bitmaps, etc.
+More precise information about pointer locations can be communicated to the
+collector using the interface in
+<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc_typedh.txt">gc_typed.h</a> in the distribution.
+<DT> <B>void * GC_MALLOC_UNCOLLECTABLE(size_t <I>nbytes</i>)</b>
+<DD>
+Identical to <TT>GC_MALLOC</tt>,
+except that the resulting object is not automatically
+deallocated.  Unlike the system-provided malloc, the collector does
+scan the object for pointers to garbage-collectable memory, even if the
+block itself does not appear to be reachable.  (Objects allocated in this way
+are effectively treated as roots by the collector.)
+<DT> <B> void * GC_REALLOC(void *<I>old</i>, size_t <I>new_size</i>) </b>
+<DD>
+Allocate a new object of the indicated size and copy (a prefix of) the
+old object into the new object.  The old object is reused in place if
+convenient.  If the original object was allocated with
+<TT>GC_MALLOC_ATOMIC</tt>,
+the new object is subject to the same constraints.  If it was allocated
+as an uncollectable object, then the new object is uncollectable, and
+the old object (if different) is deallocated.
+<DT> <B> void GC_FREE(void *<I>dead</i>) </b>
+<DD>
+Explicitly deallocate an object.  Typically not useful for small
+collectable objects.
+<DT> <B> void * GC_MALLOC_IGNORE_OFF_PAGE(size_t <I>nbytes</i>) </b>
+<DD>
+<DT> <B> void * GC_MALLOC_ATOMIC_IGNORE_OFF_PAGE(size_t <I>nbytes</i>) </b>
+<DD>
+Analogous to <TT>GC_MALLOC</tt> and <TT>GC_MALLOC_ATOMIC</tt>,
+except that the client
+guarantees that as long
+as the resulting object is of use, a pointer is maintained to someplace
+inside the first 512 bytes of the object.  This pointer should be declared
+volatile to avoid interference from compiler optimizations.
+(Other nonvolatile pointers to the object may exist as well.)
+This is the
+preferred way to allocate objects that are likely to be &gt; 100KBytes in size.
+It greatly reduces the risk that such objects will be accidentally retained
+when they are no longer needed.  Thus space usage may be significantly reduced.
+<DT> <B> void GC_INIT(void) </b>
+<DD>
+On some platforms, it is necessary to invoke this

+
+<H1>C++ Interface</h1>
+The C++ interface is implemented as a thin layer on the C interface.
+Unfortunately, this thin layer appears to be very sensitive to variations
+in C++ implementations, particularly since it tries to replace the global
+::new operator, something that appears to not be well-standardized.
+Your platform may need minor adjustments in this layer (gc_cpp.cc, gc_cpp.h,
+and possibly gc_allocator.h).  Such changes do not require understanding
+of collector internals, though they may require a good understanding of
+your platform.  (Patches enhancing portability are welcome.
+But it's easy to break one platform by fixing another.)
+<P>
+Usage of the collector from C++ is also complicated by the fact that there
+are many "standard" ways to allocate memory in C++.  The default ::new
+operator, default malloc, and default STL allocators allocate memory
+that is not garbage collected, and is not normally "traced" by the
+collector.  This means that any pointers in memory allocated by these
+default allocators will not be seen by the collector.  Garbage-collectable
+memory referenced only by pointers stored in such default-allocated
+objects is likely to be reclaimed prematurely by the collector.
+<P>
+It is the programmers responsibility to ensure that garbage-collectable
+memory is referenced by pointers stored in one of
+<UL>
+<LI> Program variables
+<LI> Garbage-collected objects
+<LI> Uncollected but "traceable" objects
+</ul>
+"Traceable" objects are not necessarily reclaimed by the collector,
+but are scanned for pointers to collectable objects.
+They are usually allocated by <TT>GC_MALLOC_UNCOLLECTABLE</tt>, as described
+above, and through some interfaces described below.
+<P>
+(On most platforms, the collector may not trace correctly from in-flight
+exception objects.  Thus objects thrown as exceptions should only
+point to otherwise reachable memory.  This is another bug whose
+proper repair requires platform hooks.)
+<P>
+The easiest way to ensure that collectable objects are properly referenced
+is to allocate only collectable objects.  This requires that every
+allocation go through one of the following interfaces, each one of
+which replaces a standard C++ allocation mechanism.  Note that
+this requires that all STL containers be explicitly instantiated with
+<TT>gc_allocator</tt>.
+<DL>
+<DT> <B> STL allocators </b>
+<DD>
+<P>
+Recent versions of the collector include a hopefully standard-conforming
+allocator implementation in <TT>gc_allocator.h</tt>.  It defines
+<UL>
+<LI> <TT>traceable_allocator</tt>
+<LI> <TT>gc_allocator</tt>
+</ul>
+which may be used either directly to allocate memory or to instantiate
+container templates. 
+The former allocates uncollectable but traced memory.
+The latter allocates garbage-collected memory.
+<P>
+These should work with any fully standard-conforming C++ compiler.
+<P>
+Users of the <A HREF="http://www.sgi.com/tech/stl">SGI extended STL</a>
+or its derivatives (including most g++ versions)
+may instead be able to include <TT>new_gc_alloc.h</tt> before including
+STL header files.  This is increasingly discouraged.
+<P>
+This defines SGI-style allocators
+<UL>
+<LI> <TT>alloc</tt>
+<LI> <TT>single_client_alloc</tt>
+<LI> <TT>gc_alloc</tt>
+<LI> <TT>single_client_gc_alloc</tt>
+</ul>
+The first two allocate uncollectable but traced
+memory, while the second two allocate collectable memory.
+The <TT>single_client</tt> versions are not safe for concurrent access by
+multiple threads, but are faster.
+<P>

+<P>
+Linking against libgccpp in addition to the gc library overrides
+::new (and friends) to allocate traceable memory but uncollectable

+On platforms which use malloc to implement ::new, it should usually be possible
+to use a version of the collector that has been compiled as a malloc
+replacement.  It is also possible to replace ::new and other allocation
+functions suitably, as is done by libgccpp.
+<P>
+Note that user-implemented small-block allocation often works poorly with
+an underlying garbage-collected large block allocator, since the collector
+has to view all objects accessible from the user's free list as reachable.
+This is likely to cause problems if <TT>GC_MALLOC</tt>
+is used with something like
+the original HP version of STL.
+This approach works well with the SGI versions of the STL only if the
+<TT>malloc_alloc</tt> allocator is used.

+<TITLE>Using the Garbage Collector as Leak Detector</title>
+</head>
+<BODY>
+<H1>Using the Garbage Collector as Leak Detector</h1>
+The garbage collector may be used as a leak detector.
+In this case, the primary function of the collector is to report
+objects that were allocated (typically with <TT>GC_MALLOC</tt>),
+not deallocated (normally with <TT>GC_FREE</tt>), but are
+no longer accessible.  Since the object is no longer accessible,
+there in normally no way to deallocate the object at a later time;
+thus it can safely be assumed that the object has been "leaked".
+<P>
+This is substantially different from counting leak detectors,
+which simply verify that all allocated objects are eventually
+deallocated.  A garbage-collector based leak detector can provide
+somewhat more precise information when an object was leaked.
+More importantly, it does not report objects that are never
+deallocated because they are part of "permanent" data structures.
+Thus it does not require all objects to be deallocated at process
+exit time, a potentially useless activity that often triggers
+large amounts of paging.
+<P>
+All non-ancient versions of the garbage collector provide
+leak detection support.  Version 5.3 adds the following
+features:
+<OL>
+<LI> Leak detection mode can be initiated at run-time by
+setting <TT>GC_find_leak</tt> instead of building the
+collector with <TT>FIND_LEAK</tt>
+defined.  This variable should be set to a nonzero value
+at program startup.
+<LI> Leaked objects should be reported and then correctly garbage collected.
+Prior versions either reported leaks or functioned as a garbage collector.
+</ol>
+For the rest of this description we will give instructions that work
+with any reasonable version of the collector.
+<P>
+To use the collector as a leak detector, follow the following steps:
+<OL>
+<LI> Build the collector with <TT>-DFIND_LEAK</tt>.  Otherwise use default
+build options.
+<LI> Change the program so that all allocation and deallocation goes
+through the garbage collector.
+<LI> Arrange to call <TT>GC_gcollect</tt> at appropriate points to check
+for leaks.
+(For sufficiently long running programs, this will happen implicitly,
+but probably not with sufficient frequency.)
+</ol>
+The second step can usually be accomplished with the
+<TT>-DREDIRECT_MALLOC=GC_malloc</tt> option when the collector is built,
+or by defining <TT>malloc</tt>, <TT>calloc</tt>,
+<TT>realloc</tt> and <TT>free</tt>
+to call the corresponding garbage collector functions.
+But this, by itself, will not yield very informative diagnostics,
+since the collector does not keep track of information about
+how objects were allocated.  The error reports will include
+only object addresses.
+<P>
+For more precise error reports, as much of the program as possible
+should use the all uppercase variants of these functions, after
+defining <TT>GC_DEBUG</tt>, and then including <TT>gc.h</tt>.
+In this environment <TT>GC_MALLOC</tt> is a macro which causes
+at least the file name and line number at the allocation point to
+be saved as part of the object.  Leak reports will then also include
+this information.
+<P>
+Many collector features (<I>e.g</i> stubborn objects, finalization,
+and disappearing links) are less useful in this context, and are not
+fully supported.  Their use will usually generate additional bogus
+leak reports, since the collector itself drops some associated objects.
+<P>
+The same is generally true of thread support.  However, as of 6.0alpha4,
+correct leak reports should be generated with linuxthreads.
+<P>
+On a few platforms (currently Solaris/SPARC, Irix, and, with -DSAVE_CALL_CHAIN,
+Linux/X86), <TT>GC_MALLOC</tt>
+also causes some more information about its call stack to be saved
+in the object.  Such information is reproduced in the error
+reports in very non-symbolic form, but it can be very useful with the
+aid of a debugger.
+<H2>An Example</h2>
+The following header file <TT>leak_detector.h</tt> is included in the
+"include" subdirectory of the distribution:
+<PRE>
+#define GC_DEBUG
+#include "gc.h"
+#define malloc(n) GC_MALLOC(n)
+#define calloc(m,n) GC_MALLOC((m)*(n))
+#define free(p) GC_FREE(p)
+#define realloc(p,n) GC_REALLOC((p),(n))
+#define CHECK_LEAKS() GC_gcollect()
+</pre>
+<P>
+Assume the collector has been built with <TT>-DFIND_LEAK</tt>.  (For
+newer versions of the collector, we could instead add the statement
+<TT>GC_find_leak = 1</tt> as the first statement in <TT>main()</tt>.
+<P>
+The program to be tested for leaks can then look like:
+<PRE>
+#include "leak_detector.h"
+
+main() {
+    int *p[10];
+    int i;
+    /* GC_find_leak = 1; for new collector versions not        */
+    /* compiled with -DFIND_LEAK.                              */
+    for (i = 0; i &lt; 10; ++i) {
+       p[i] = malloc(sizeof(int)+i);
+    }
+    for (i = 1; i &lt; 10; ++i) {
+       free(p[i]);
+    }
+    for (i = 0; i &lt; 9; ++i) {
+       p[i] = malloc(sizeof(int)+i);
+    }
+    CHECK_LEAKS();
+}      
+</pre>
+<P>
+On an Intel X86 Linux system this produces on the stderr stream:
+<PRE>
+Leaked composite object at 0x806dff0 (leak_test.c:8, sz=4)
+</pre>
+(On most unmentioned operating systems, the output is similar to this.
+If the collector had been built on Linux/X86 with -DSAVE_CALL_CHAIN,
+the output would be closer to the Solaris example. For this to work,
+the program should not be compiled with -fomit_frame_pointer.)
+<P>
+On Irix it reports
+<PRE>
+Leaked composite object at 0x10040fe0 (leak_test.c:8, sz=4)
+        Caller at allocation:
+                ##PC##= 0x10004910
+</pre>
+and on Solaris the error report is
+<PRE>
+Leaked composite object at 0xef621fc8 (leak_test.c:8, sz=4)
+        Call chain at allocation:
+                args: 4 (0x4), 200656 (0x30FD0)
+                ##PC##= 0x14ADC
+                args: 1 (0x1), -268436012 (0xEFFFFDD4)
+                ##PC##= 0x14A64
+</pre>
+In the latter two cases some additional information is given about
+how malloc was called when the leaked object was allocated.  For
+Solaris, the first line specifies the arguments to <TT>GC_debug_malloc</tt>
+(the actual allocation routine), The second the program counter inside
+main, the third the arguments to <TT>main</tt>, and finally the program
+counter inside the caller to main (i.e. in the C startup code).
+<P>
+In the Irix case, only the address inside the caller to main is given.
+<P>
+In many cases, a debugger is needed to interpret the additional information.
+On systems supporting the "adb" debugger, the <TT>callprocs</tt> script
+can be used to replace program counter values with symbolic names.
+As of version 6.1, the collector tries to generate symbolic names for
+call stacks if it knows how to do so on the platform.  This is true on
+Linux/X86, but not on most other platforms.
+<H2>Simplified leak detection under Linux</h2>
+Since version 6.1, it should be possible to run the collector in leak
+detection mode on a program a.out under Linux/X86 as follows:
+<OL>
+<LI> <I>Ensure that a.out is a single-threaded executable, or you are using
+a very recent (7.0alpha7+) collector version on Linux.</i>
+On most platforms this does not
+work at all for multithreaded programs.
+<LI> If possible, ensure that the <TT>addr2line</tt> program is installed in
+<TT>/usr/bin</tt>.  (It comes with most Linux distributions.)
+<LI> If possible, compile your program, which we'll call <TT>a.out</tt>,
+with full debug information.
+This will improve the quality of the leak reports.  With this approach, it is
+no longer necessary to call <TT>GC_</tt> routines explicitly,
+though that can also
+improve the quality of the leak reports.
+<LI> Build the collector and install it in directory <I>foo</i> as follows:
+<UL>
+<LI> <TT>configure --prefix=<I>foo</i> --enable-gc-debug --enable-redirect-malloc
+--disable-threads</tt>
+<LI> <TT>make</tt>
+<LI> <TT>make install</tt>
+</ul>
+With a very recent collector on Linux, it may sometimes be safe to omit
+the <TT>--disable-threads</tt>.  But the combination of thread support
+and <TT>malloc</tt> replacement is not yet rock solid.
+<LI> Set environment variables as follows:
+<UL>
+<LI> <TT>LD_PRELOAD=</tt><I>foo</i><TT>/lib/libgc.so</tt>
+<LI> <TT>GC_FIND_LEAK</tt>
+<LI> You may also want to set <TT>GC_PRINT_STATS</tt>
+(to confirm that the collector is running) and/or
+<TT>GC_LOOP_ON_ABORT</tt> (to facilitate debugging from another
+window if something goes wrong).
+</ul>
+<LI> Simply run <TT>a.out</tt> as you normally would.  Note that if you run anything
+else (<I>e.g.</i> your editor) with those environment variables set,
+it will also be leak tested.  This may or may not be useful and/or
+embarrassing.  It can generate
+mountains of leak reports if the application wasn't designed to avoid leaks,
+<I>e.g.</i> because it's always short-lived.
+</ol>
+This has not yet been thoroughly tested on large applications, but it's known
+to do the right thing on at least some small ones.

+conservative garbage collector can
+be used as a garbage collecting
+replacement for C <tt>malloc</tt> or C++ <tt>new</tt>.
+It allows you to allocate memory basically as you normally would,
+without explicitly deallocating memory that is no longer useful.
+The collector automatically recycles memory when it determines
+that it can no longer be otherwise accessed.
+A simple example of such a use is given
+<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/simple_example.html">here</a>.
+</p><p>
+The collector is also used by a number of programming language
+implementations that either use C as intermediate code, want
+to facilitate easier interoperation with C libraries, or
+just prefer the simple collector interface.
+For a more detailed description of the interface, see
+<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcinterface.html">here</a>.
+</p><p>
+Alternatively, the garbage collector  may be used as
+a <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/leak.html">leak detector</a>
+for C or C++ programs, though that is not its primary goal.
+</p><p>
+Typically several versions will be available.
+Usually you should first try to use
+<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc.tar.gz"><tt>gc_source/gc.tar.gz</tt></a>,
+which is normally an older, more stable version.
+</p><p>
+If that fails, try the latest explicitly numbered version
+in <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/">
+<tt>gc_source/</tt></a>.
+Later versions may contain additional features, platform support,
+or bug fixes, but are likely to be less well tested.
+Note that versions containing the letters <tt>alpha</tt> are even less
+well tested than others, especially on non-HP platforms.
+</p><p>
+A slightly older version of the garbage collector is now also
+included as part of the
+<a href="http://gcc.gnu.org/">GNU compiler</a>
+distribution.  The source
+code for that version is available for browsing
+<a href="http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/boehm-gc/">here</a>.
+</p><p>
+The arguments for and against conservative garbage collection
+in C and C++ are briefly
+discussed in
+<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/issues.html">issues.html</a>.  The beginnings of

+WITH ABSOLUTELY NO WARRANTY EXPRESSED OR IMPLIED.  ANY USE IS AT YOUR OWN RISK</b>.
+</p><p>
+Empirically, this collector works with most unmodified C programs,
+simply by replacing
+<tt>malloc</tt> with <tt>GC_malloc</tt> calls,
+replacing <tt>realloc</tt> with <tt>GC_realloc</tt> calls, and removing
+free calls.  Exceptions are discussed
+in <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/issues.html">issues.html</a>. 
+</p><h2><a name="platforms">Platforms</a></h2>
+The collector is not completely portable, but the distribution
+includes ports to most standard PC and UNIX/Linux platforms.
+The collector should work on Linux, *BSD, recent Windows versions,
+MacOS X, HP/UX, Solaris,
+Tru64, Irix and a few other operating systems.
+Some ports are more polished than others.
+<p>
+Irix pthreads, Linux threads, Win32 threads, Solaris threads
+(pthreads only),
+HP/UX 11 pthreads, Tru64 pthreads, and MacOS X threads are supported
+in recent versions.
+</p><h3>Separately distributed ports</h3>
+For MacOS 9/Classic use, Patrick Beard's latest port is available from
+<a href="http://homepage.mac.com/pcbeard/gc/">
+<tt>http://homepage.mac.com/pcbeard/gc/</tt></a>.
+(Unfortunately, that's now quite dated.
+I'm not in a position to test under MacOS.  Although I try to
+incorporate changes, it is impossible for
+me to update the project file.)
+<p>
+Precompiled versions of the collector for NetBSD are available
+<a href="ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/devel/boehm-gc/README.html">here</a>
+or
+<a href="http://www.netbsd.org/packages/devel/boehm-gc/README.html">here</a>.
+</p><p>
+<a href="http://www.debian.org/">Debian Linux</a> includes prepackaged
+versions of the collector.
+</p><h2><a name="multiprocessors">Scalable multiprocessor versions</a></h2>
+Kenjiro Taura, Toshio Endo, and Akinori Yonezawa have made available
+a <a href="http://www.yl.is.s.u-tokyo.ac.jp/gc/">parallel collector</a>
+based on this one.  Their collector takes advantage of multiple processors
+during a collection.  Starting with collector version 6.0alpha1
+we also do this, though with more modest processor scalability goals.
+Our approach is discussed briefly in
+<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/scale.html"><tt>scale.html</tt></a>.
+<h2><a name="details">Some Collector Details</a></h2>
+The collector uses a <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/complexity.html">mark-sweep</a> algorithm.
+It provides incremental and generational
+collection under operating systems which provide the right kind of
+virtual memory support.  (Currently this includes SunOS[45], IRIX,
+OSF/1, Linux, and Windows, with varying restrictions.)
+It allows <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/finalization.html"><i>finalization</i></a> code
+to be invoked when an object is collected.
+It can take advantage of type information to locate pointers if such
+information is provided, but it is usually used without such information.
+ee the README and
+<tt>gc.h</tt> files in the distribution for more details.
+<p>
+For an overview of the implementation, see <a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcdescr.html">here</a>.
+</p><p>
+The garbage collector distribution includes a C string
+(<a href="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/cordh.txt"><i>cord</i></a>) package that provides
+for fast concatenation and substring operations on long strings.
+A simple curses- and win32-based editor that represents the entire file
+as a cord is included as a
+sample application.
+</p><p>
+Performance of the nonincremental collector is typically competitive
+with malloc/free implementations.  Both space and time overhead are
+likely to be only slightly higher
+for programs written for malloc/free
+(see Detlefs, Dosser and Zorn's
+<a href="ftp://ftp.cs.colorado.edu/pub/techreports/zorn/CU-CS-665-93.ps.Z">Memory Allocation Costs in Large C and C++ Programs</a>.)
+For programs allocating primarily very small objects, the collector
+may be faster; for programs allocating primarily large objects it will
+be slower.  If the collector is used in a multithreaded environment
+and configured for thread-local allocation, it may in some cases
+significantly outperform malloc/free allocation in time.
+</p><p>
+We also expect that in many cases any additional overhead
+will be more than compensated for by decreased copying etc.
+if programs are written
+and tuned for garbage collection.

+<BODY>
+<H1>Conservative GC Porting Directions</h1>
+The collector is designed to be relatively easy to port, but is not
+portable code per se.  The collector inherently has to perform operations,
+such as scanning the stack(s), that are not possible in portable C code.
+<P>
+All of the following assumes that the collector is being ported to a
+byte-addressable 32- or 64-bit machine.  Currently all successful ports
+to 64-bit machines involve LP64 targets.  The code base includes some
+provisions for P64 targets (notably win64), but that has not been tested.
+You are hereby discouraged from attempting a port to non-byte-addressable,
+or 8-bit, or 16-bit machines.
+<P>
+The difficulty of porting the collector varies greatly depending on the needed
+functionality.  In the simplest case, only some small additions are needed
+for the <TT>include/private/gcconfig.h</tt> file.  This is described in the
+following section.  Later sections discuss some of the optional features,
+which typically involve more porting effort.
+<P>
+Note that the collector makes heavy use of <TT>ifdef</tt>s.  Unlike
+some other software projects, we have concluded repeatedly that this is preferable
+to system dependent files, with code duplicated between the files.
+However, to keep this manageable, we do strongly believe in indenting
+<TT>ifdef</tt>s correctly (for historical reasons usually without the leading
+sharp sign).  (Separate source files are of course fine if they don't result in
+code duplication.)
+<H2>Adding Platforms to <TT>gcconfig.h</tt></h2>
+If neither thread support, nor tracing of dynamic library data is required,
+these are often the only changes you will need to make.
+<P>
+The <TT>gcconfig.h</tt> file consists of three sections:
+<OL>
+<LI> A section that defines GC-internal macros
+that identify the architecture (e.g. <TT>IA64</tt> or <TT>I386</tt>)
+and operating system (e.g. <TT>LINUX</tt> or <TT>MSWIN32</tt>).
+This is usually done by testing predefined macros.  By defining
+our own macros instead of using the predefined ones directly, we can
+impose a bit more consistency, and somewhat isolate ourselves from
+compiler differences.
+<P>
+It is relatively straightforward to add a new entry here.  But please try
+to be consistent with the existing code.  In particular, 64-bit variants
+of 32-bit architectures general are <I>not</i> treated as a new architecture.
+Instead we explicitly test for 64-bit-ness in the few places in which it
+matters.  (The notable exception here is <TT>I386</tt> and <TT>X86_64</tt>.
+This is partially historical, and partially justified by the fact that there
+are arguably more substantial architecture and ABI differences here than
+for RISC variants.)
+<P>
+on GNU-based systems, <TT>cpp -dM empty_source_file.c</tt> seems to generate
+a set of predefined macros.  On some other systems, the "verbose"
+compiler option may do so, or the manual page may list them.
+<LI>
+A section that defines a small number of platform-specific macros, which are
+then used directly by the collector.  For simple ports, this is where most of
+the effort is required.  We describe the macros below.
+<P>
+This section contains a subsection for each architecture (enclosed in a
+suitable <TT>ifdef</tt>.  Each subsection usually contains some
+architecture-dependent defines, followed by several sets of OS-dependent
+defines, again enclosed in <TT>ifdef</tt>s.
+<LI>
+A section that fills in defaults for some macros left undefined in the preceding
+section, and defines some other macros that rarely need adjustment for
+new platforms.  You will typically not have to touch these.
+If you are porting to an OS that
+was previously completely unsupported, it is likely that you will
+need to add another clause to the definition of <TT>GET_MEM</tt>.
+</ol>
+The following macros must be defined correctly for each architecture and operating
+system:
+<DL>
+<DT><TT>MACH_TYPE</tt>
+<DD>
+Defined to a string that represents the machine architecture.  Usually
+just the macro name used to identify the architecture, but enclosed in quotes.
+<DT><TT>OS_TYPE</tt>
+<DD>
+Defined to a string that represents the operating system name.  Usually
+just the macro name used to identify the operating system, but enclosed in quotes.
+<DT><TT>CPP_WORDSZ</tt>
+<DD>
+The word size in bits as a constant suitable for preprocessor tests,
+i.e. without casts or sizeof expressions.  Currently always defined as
+either 64 or 32.  For platforms supporting both 32- and 64-bit ABIs,
+this should be conditionally defined depending on the current ABI.
+There is a default of 32.
+<DT><TT>ALIGNMENT</tt>
+<DD>
+Defined to be the largest <TT>N</tt>, such that
+all pointer are guaranteed to be aligned on <TT>N</tt>-byte boundaries.
+defining it to be 1 will always work, but perform poorly.
+For all modern 32-bit platforms, this is 4.  For all modern 64-bit
+platforms, this is 8.  Whether or not X86 qualifies as a modern
+architecture here is compiler- and OS-dependent.
+<DT><TT>DATASTART</tt>
+<DD>
+The beginning of the main data segment.  The collector will trace all
+memory between <TT>DATASTART</tt> and <TT>DATAEND</tt> for root pointers.
+On some platforms,this can be defined to a constant address,
+though experience has shown that to be risky.  Ideally the linker will
+define a symbol (e.g. <TT>_data</tt> whose address is the beginning
+of the data segment.  Sometimes the value can be computed using
+the <TT>GC_SysVGetDataStart</tt> function.  Not used if either
+the next macro is defined, or if dynamic loading is supported, and the
+dynamic loading support defines a function
+<TT>GC_register_main_static_data()</tt> which returns false.
+<DT><TT>SEARCH_FOR_DATA_START</tt>
+<DD>
+If this is defined <TT>DATASTART</tt> will be defined to a dynamically
+computed value which is obtained by starting with the address of
+<TT>_end</tt> and walking backwards until non-addressable memory is found.
+This often works on Posix-like platforms.  It makes it harder to debug
+client programs, since startup involves generating and catching a
+segmentation fault, which tends to confuse users.
+<DT><TT>DATAEND</tt>
+<DD>
+Set to the end of the main data segment.  Defaults to <TT>end</tt>,
+where that is declared as an array.  This works in some cases, since
+the linker introduces a suitable symbol.
+<DT><TT>DATASTART2, DATAEND2</tt>
+<DD>
+Some platforms have two discontiguous main data segments, e.g.
+for initialized and uninitialized data.  If so, these two macros
+should be defined to the limits of the second main data segment.
+<DT><TT>STACK_GROWS_UP</tt>
+<DD>
+Should be defined if the stack (or thread stacks) grow towards higher
+addresses.  (This appears to be true only on PA-RISC.  If your architecture
+has more than one stack per thread, and is not already supported, you will
+need to do more work.  Grep for "IA64" in the source for an example.)
+<DT><TT>STACKBOTTOM</tt>
+<DD>
+Defined to be the cool end of the stack, which is usually the
+highest address in the stack.  It must bound the region of the
+stack that contains pointers into the GC heap.  With thread support,
+this must be the cold end of the main stack, which typically
+cannot be found in the same way as the other thread stacks.
+If this is not defined and none of the following three macros
+is defined, client code must explicitly set
+<TT>GC_stackbottom</tt> to an appropriate value before calling
+<TT>GC_INIT()</tt> or any other <TT>GC_</tt> routine.
+<DT><TT>LINUX_STACKBOTTOM</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+If defined, then the cold end of the stack will be determined
+Currently we usually read it from /proc.
+<DT><TT>HEURISTIC1</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+<TT>STACK_GRAN</tt> should generally also be undefined and defined.
+The cold end of the stack is determined by taking an address inside
+<TT>GC_init's frame</tt>, and rounding it up to
+the next multiple of <TT>STACK_GRAN</tt>.  This works well if the stack base is
+always aligned to a large power of two.
+(<TT>STACK_GRAN</tt> is predefined to 0x1000000, which is
+rarely optimal.)
+<DT><TT>HEURISTIC2</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+The cold end of the stack is determined by taking an address inside
+GC_init's frame, incrementing it repeatedly
+in small steps (decrement if <TT>STACK_GROWS_UP</tt>), and reading the value
+at each location.  We remember the value when the first
+Segmentation violation or Bus error is signalled, round that
+to the nearest plausible page boundary, and use that as the
+stack base.
+<DT><TT>DYNAMIC_LOADING</tt>
+<DD>
+Should be defined if <TT>dyn_load.c</tt> has been updated for this
+platform and tracing of dynamic library roots is supported.
+<DT><TT>MPROTECT_VDB, PROC_VDB</tt>
+<DD>
+May be defined if the corresponding "virtual dirty bit"
+implementation in os_dep.c is usable on this platform.  This
+allows incremental/generational garbage collection.
+<TT>MPROTECT_VDB</tt> identifies modified pages by
+write protecting the heap and catching faults.
+<TT>PROC_VDB</tt> uses the /proc primitives to read dirty bits.
+<DT><TT>PREFETCH, PREFETCH_FOR_WRITE</tt>
+<DD>
+The collector uses <TT>PREFETCH</tt>(<I>x</i>) to preload the cache
+with *<I>x</i>.
+This defaults to a no-op.
+<DT><TT>CLEAR_DOUBLE</tt>
+<DD>
+If <TT>CLEAR_DOUBLE</tt> is defined, then
+<TT>CLEAR_DOUBLE</tt>(x) is used as a fast way to
+clear the two words at GC_malloc-aligned address x.  By default,
+word stores of 0 are used instead.
+<DT><TT>HEAP_START</tt>
+<DD>
+<TT>HEAP_START</tt> may be defined as the initial address hint for mmap-based
+allocation.
+<DT><TT>ALIGN_DOUBLE</tt>
+<DD>
+Should be defined if the architecture requires double-word alignment
+of <TT>GC_malloc</tt>ed memory, e.g. 8-byte alignment with a
+32-bit ABI.  Most modern machines are likely to require this.
+This is no longer needed for GC7 and later.
+</dl>
+<H2>Additional requirements for a basic port</h2>
+In some cases, you may have to add additional platform-specific code
+to other files.  A likely candidate is the implementation of
+<TT>GC_with_callee_saves_pushed</tt> in </tt>mach_dep.c</tt>.
+This ensure that register contents that the collector must trace
+from are copied to the stack.  Typically this can be done portably,
+but on some platforms it may require assembly code, or just
+tweaking of conditional compilation tests.
+<P>
+For GC7, if your platform supports <TT>getcontext()</tt>, then definining
+the macro <TT>UNIX_LIKE</tt> for your OS in <TT>gcconfig.h</tt>
+(if it isn't defined there already) is likely to solve the problem.
+otherwise, if you are using gcc, <TT>_builtin_unwind_init()</tt>
+will be used, and should work fine.  If that is not applicable either,
+the implementation will try to use <TT>setjmp()</tt>.  This will work if your
+<TT>setjmp</tt> implementation saves all possibly pointer-valued registers
+into the buffer, as opposed to trying to unwind the stack at
+<TT>longjmp</tt> time.  The <TT>setjmp_test</tt> test tries to determine this,
+but often doesn't get it right.
+<P>
+In GC6.x versions of the collector, tracing of registers
+was more commonly handled
+with assembly code.  In GC7, this is generally to be avoided.
+<P>
+Most commonly <TT>os_dep.c</tt> will not require attention, but see below.
+<H2>Thread support</h2>
+Supporting threads requires that the collector be able to find and suspend
+all threads potentially accessing the garbage-collected heap, and locate
+any state associated with each thread that must be traced.
+<P>
+The functionality needed for thread support is generally implemented
+in one or more files specific to the particular thread interface.
+For example, somewhat portable pthread support is implemented
+in <TT>pthread_support.c</tt> and <TT>pthread_stop_world.c</tt>.
+The essential functionality consists of
+<DL>
+<DT><TT>GC_stop_world()</tt>
+<DD>
+Stops all threads which may access the garbage collected heap, other
+than the caller.
+<DT><TT>GC_start_world()</tt>
+<DD>
+Restart other threads.
+<DT><TT>GC_push_all_stacks()</tt>
+<DD>
+Push the contents of all thread stacks (or at least of pointer-containing
+regions in the thread stacks) onto the mark stack.
+</dl>
+These very often require that the garbage collector maintain its
+own data structures to track active threads.
+<P>
+In addition, <TT>LOCK</tt> and <TT>UNLOCK</tt> must be implemented
+in <TT>gc_locks.h</tt>
+<P>
+The easiest case is probably a new pthreads platform
+on which threads can be stopped
+with signals.  In this case, the changes involve:
+<OL>
+<LI>Introducing a suitable <TT>GC_</tt><I>X</i><TT>_THREADS</tt> macro, which should
+be automatically defined by <TT>gc_config_macros.h</tt> in the right cases.
+It should also result in a definition of <TT>GC_PTHREADS</tt>, as for the
+existing cases.
+<LI>For GC7+, ensuring that the <TT>atomic_ops</tt> package at least
+minimally supports the platform.
+If incremental GC is needed, or if pthread locks don't
+perform adequately as the allocation lock, you will probably need to
+ensure that a sufficient <TT>atomic_ops</tt> port
+exists for the platform to provided an atomic test and set
+operation.  (Current GC7 versions require more<TT>atomic_ops</tt>
+asupport than necessary.  This is a bug.)  For earlier versions define
+<TT>GC_test_and_set</tt> in <TT>gc_locks.h</tt>.
+<LI>Making any needed adjustments to <TT>pthread_stop_world.c</tt> and
+<TT>pthread_support.c</tt>.  Ideally none should be needed.  In fact,
+not all of this is as well standardized as one would like, and outright
+bugs requiring workarounds are common.
+</ol>
+Non-preemptive threads packages will probably require further work.  Similarly
+thread-local allocation and parallel marking requires further work
+in <TT>pthread_support.c</tt>, and may require better <TT>atomic_ops</tt>
+support.
+<H2>Dynamic library support</h2>
+So long as <TT>DATASTART</tt> and <TT>DATAEND</tt> are defined correctly,
+the collector will trace memory reachable from file scope or <TT>static</tt>
+variables defined as part of the main executable.  This is sufficient
+if either the program is statically linked, or if pointers to the
+garbage-collected heap are never stored in non-stack variables
+defined in dynamic libraries.
+<P>
+If dynamic library data sections must also be traced, then
+<UL>
+<LI><TT>DYNAMIC_LOADING</tt> must be defined in the appropriate section
+of <TT>gcconfig.h</tt>.
+<LI>An appropriate versions of the functions

+on each dynamic library data section.
+</ul>
+<P>
+Implementations that scan for writable data segments are error prone, particularly
+in the presence of threads.  They frequently result in race conditions
+when threads exit and stacks disappear.  They may also accidentally trace
+large regions of graphics memory, or mapped files.  On at least
+one occasion they have been known to try to trace device memory that
+could not safely be read in the manner the GC wanted to read it.
+<P>
+It is usually safer to walk the dynamic linker data structure, especially
+if the linker exports an interface to do so.  But beware of poorly documented
+locking behavior in this case.
+<H2>Incremental GC support</h2>
+For incremental and generational collection to work, <TT>os_dep.c</tt>
+must contain a suitable "virtual dirty bit" implementation, which
+allows the collector to track which heap pages (assumed to be
+a multiple of the collectors block size) have been written during
+a certain time interval.  The collector provides several
+implementations, which might be adapted.  The default
+(<TT>DEFAULT_VDB</tt>) is a placeholder which treats all pages
+as having been written.  This ensures correctness, but renders
+incremental and generational collection essentially useless.
+<H2>Stack traces for debug support</h2>
+If stack traces in objects are need for debug support,
+<TT>GC_dave_callers</tt> and <TT>GC_print_callers</tt> must be
+implemented.
+<H2>Disclaimer</h2>
+This is an initial pass at porting guidelines.  Some things
+have no doubt been overlooked.

+<TITLE>Garbage collector scalability</TITLE>
+</HEAD>
+<BODY>
+<H1>Garbage collector scalability</h1>
+In its default configuration, the Boehm-Demers-Weiser garbage collector
+is not thread-safe.  It can be made thread-safe for a number of environments
+by building the collector with the appropriate
+<TT>-D</tt><I>XXX</i><TT>-THREADS</tt> compilation
+flag.  This has primarily two effects:
+<OL>
+<LI> It causes the garbage collector to stop all other threads when
+it needs to see a consistent memory state.
+<LI> It causes the collector to acquire a lock around essentially all
+allocation and garbage collection activity.
+</ol>
+Since a single lock is used for all allocation-related activity, only one
+thread can be allocating or collecting at one point.  This inherently
+limits performance of multi-threaded applications on multiprocessors.
+<P>
+On most platforms, the allocator/collector lock is implemented as a
+spin lock with exponential back-off.  Longer wait times are implemented
+by yielding and/or sleeping.  If a collection is in progress, the pure
+spinning stage is skipped.  This has the advantage that uncontested and
+thus most uniprocessor lock acquisitions are very cheap.  It has the
+disadvantage that the application may sleep for small periods of time
+even when there is work to be done.  And threads may be unnecessarily
+woken up for short periods.  Nonetheless, this scheme empirically
+outperforms native queue-based mutual exclusion implementations in most
+cases, sometimes drastically so.
+<H2>Options for enhanced scalability</h2>
+Version 6.0 of the collector adds two facilities to enhance collector
+scalability on multiprocessors.  As of 6.0alpha1, these are supported 
+only under Linux on X86 and IA64 processors, though ports to other
+otherwise supported Pthreads platforms should be straightforward.
+They are intended to be used together.
+<UL>
+<LI>
+Building the collector with <TT>-DPARALLEL_MARK</tt> allows the collector to
+run the mark phase in parallel in multiple threads, and thus on multiple
+processors.  The mark phase typically consumes the large majority of the
+collection time.  Thus this largely parallelizes the garbage collector
+itself, though not the allocation process.  Currently the marking is
+performed by the thread that triggered the collection, together with
+<I>N</i>-1 dedicated
+threads, where <I>N</i> is the number of processors detected by the collector.
+The dedicated threads are created once at initialization time.
+<P>
+A second effect of this flag is to switch to a more concurrent
+implementation of <TT>GC_malloc_many</tt>, so that free lists can be
+built, and memory can be cleared, by more than one thread concurrently.
+<LI>
+Building the collector with -DTHREAD_LOCAL_ALLOC adds support for thread
+local allocation.  This causes GC_malloc, GC_malloc_atomic, and
+GC_gcj_malloc to be redefined to perform thread-local allocation.
+<P>
+Memory returned from thread-local allocators is completely interchangeable
+with that returned by the standard allocators.  It may be used by other
+threads.  The only difference is that, if the thread allocates enough
+memory of a certain kind, it will build a thread-local free list for
+objects of that kind, and allocate from that.  This greatly reduces
+locking.  The thread-local free lists are refilled using 
+<TT>GC_malloc_many</tt>.
+<P>
+An important side effect of this flag is to replace the default
+spin-then-sleep lock to be replace by a spin-then-queue based implementation.
+This <I>reduces performance</i> for the standard allocation functions,
+though it usually improves performance when thread-local allocation is
+used heavily, and thus the number of short-duration lock acquisitions
+is greatly reduced.
+</ul>
+<P>
+The easiest way to switch an application to thread-local allocation
+in a pre-version-7.0 collector was to
+<OL>
+<LI> Define the macro <TT>GC_REDIRECT_TO_LOCAL</tt>,
+and then include the <TT>gc.h</tt>
+header in each client source file.
+<LI> Invoke <TT>GC_thr_init()</tt> before any allocation.
+<LI> Allocate using <TT>GC_MALLOC</tt>, <TT>GC_MALLOC_ATOMIC</tt>,
+and/or <TT>GC_GCJ_MALLOC</tt>.
+</ol>
+<H2>The Parallel Marking Algorithm</h2>
+We use an algorithm similar to
+<A HREF="http://www.yl.is.s.u-tokyo.ac.jp/gc/">that developed by
+Endo, Taura, and Yonezawa</a> at the University of Tokyo.
+However, the data structures and implementation are different,
+and represent a smaller change to the original collector source,
+probably at the expense of extreme scalability.  Some of
+the refinements they suggest, <I>e.g.</i> splitting large
+objects, were also incorporated into out approach.
+<P>
+The global mark stack is transformed into a global work queue.
+Unlike the usual case, it never shrinks during a mark phase.
+The mark threads remove objects from the queue by copying them to a
+local mark stack and changing the global descriptor to zero, indicating
+that there is no more work to be done for this entry.
+This removal
+is done with no synchronization.  Thus it is possible for more than
+one worker to remove the same entry, resulting in some work duplication.
+<P>
+The global work queue grows only if a marker thread decides to
+return some of its local mark stack to the global one.  This
+is done if the global queue appears to be running low, or if
+the local stack is in danger of overflowing.  It does require
+synchronization, but should be relatively rare.
+<P>
+The sequential marking code is reused to process local mark stacks.
+Hence the amount of additional code required for parallel marking
+is minimal.
+<P>
+It should be possible to use generational collection in the presence of the
+parallel collector, by calling <TT>GC_enable_incremental()</tt>.
+This does not result in fully incremental collection, since parallel mark
+phases cannot currently be interrupted, and doing so may be too
+expensive.
+<P>
+Gcj-style mark descriptors do not currently mix with the combination
+of local allocation and incremental collection.  They should work correctly
+with one or the other, but not both.
+<P>
+The number of marker threads is set on startup to the number of
+available processors (or to the value of the <TT>GC_NPROCS</tt>
+environment variable).  If only a single processor is detected,
+parallel marking is disabled.
+<P>
+Note that setting GC_NPROCS to 1 also causes some lock acquisitions inside
+the collector to immediately yield the processor instead of busy waiting
+first.  In the case of a multiprocessor and a client with multiple
+simultaneously runnable threads, this may have disastrous performance
+consequences (e.g. a factor of 10 slowdown). 
+<H2>Performance</h2>
+We conducted some simple experiments with a version of
+<A HREF="gc_bench.html">our GC benchmark</a> that was slightly modified to
+run multiple concurrent client threads in the same address space.
+Each client thread does the same work as the original benchmark, but they share
+a heap.
+This benchmark involves very little work outside of memory allocation.
+This was run with GC 6.0alpha3 on a dual processor Pentium III/500 machine
+under Linux 2.2.12.
+<P>
+Running with a thread-unsafe collector,  the benchmark ran in 9
+seconds.  With the simple thread-safe collector,
+built with <TT>-DLINUX_THREADS</tt>, the execution time
+increased to 10.3 seconds, or 23.5 elapsed seconds with two clients.
+(The times for the <TT>malloc</tt>/i<TT>free</tt> version
+with glibc <TT>malloc</tt>
+are 10.51 (standard library, pthreads not linked),
+20.90 (one thread, pthreads linked),
+and 24.55 seconds respectively. The benchmark favors a
+garbage collector, since most objects are small.)
+<P>
+The following table gives execution times for the collector built
+with parallel marking and thread-local allocation support
+(<TT>-DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC</tt>).  We tested
+the client using either one or two marker threads, and running
+one or two client threads.  Note that the client uses thread local
+allocation exclusively.  With -DTHREAD_LOCAL_ALLOC the collector
+switches to a locking strategy that is better tuned to less frequent
+lock acquisition.  The standard allocation primitives thus perform
+slightly worse than without -DTHREAD_LOCAL_ALLOC, and should be
+avoided in time-critical code.
+<P>
+(The results using <TT>pthread_mutex_lock</tt>
+directly for allocation locking would have been worse still, at
+least for older versions of linuxthreads.
+With THREAD_LOCAL_ALLOC, we first repeatedly try to acquire the
+lock with pthread_mutex_try_lock(), busy_waiting between attempts.
+After a fixed number of attempts, we use pthread_mutex_lock().)
+<P>
+These measurements do not use incremental collection, nor was prefetching
+enabled in the marker.  We used the C version of the benchmark.
+All measurements are in elapsed seconds on an unloaded machine.
+<P>
+<TABLE BORDER ALIGN="CENTER">
+<TR><TH>Number of threads</th><TH>1 marker thread (secs.)</th>
+<TH>2 marker threads (secs.)</th></tr>
+<TR><TD>1 client</td><TD ALIGN="CENTER">10.45</td><TD ALIGN="CENTER">7.85</td>
+<TR><TD>2 clients</td><TD ALIGN="CENTER">19.95</td><TD ALIGN="CENTER">12.3</td>
+</table>
+<PP>
+The execution time for the single threaded case is slightly worse than with
+simple locking.  However, even the single-threaded benchmark runs faster than
+even the thread-unsafe version if a second processor is available.
+The execution time for two clients with thread local allocation time is
+only 1.4 times the sequential execution time for a single thread in a
+thread-unsafe environment, even though it involves twice the client work.
+That represents close to a
+factor of 2 improvement over the 2 client case with the old collector.
+The old collector clearly
+still suffered from some contention overhead, in spite of the fact that the
+locking scheme had been fairly well tuned.
+<P>
+Full linear speedup (i.e. the same execution time for 1 client on one
+processor as 2 clients on 2 processors)
+is probably not achievable on this kind of
+hardware even with such a small number of processors,
+since the memory system is
+a major constraint for the garbage collector,
+the processors usually share a single memory bus, and thus
+the aggregate memory bandwidth does not increase in
+proportion to the number of processors. 
+<P>
+These results are likely to be very sensitive to both hardware and OS
+issues.  Preliminary experiments with an older Pentium Pro machine running
+an older kernel were far less encouraging.

+</head>
+<BODY>
+<H1>Using the Garbage Collector: A simple example</h1>
+The following consists of step-by-step instructions for building and
+using the collector.  We'll assume a Linux/gcc platform and
+a single-threaded application.  <FONT COLOR=green>The green
+text contains information about other platforms or scenarios.
+It can be skipped, especially on first reading</font>.
+<H2>Building the collector</h2>
+If you haven't already so, unpack the collector and enter
+the newly created directory with
+<PRE>
+tar xvfz gc&lt;version&gt;.tar.gz
+cd gc&lt;version&gt;
+</pre>
+<P>
+You can configure, build, and install the collector in a private
+directory, say /home/xyz/gc, with the following commands:
+<PRE>
+./configure --prefix=/home/xyz/gc --disable-threads
+make
+make check
+make install
+</pre>
+Here the "<TT>make check</tt>" command is optional, but highly recommended.
+It runs a basic correctness test which usually takes well under a minute.
+<H3><FONT COLOR=green>Other platforms</font></h3>
+<FONT COLOR=green>
+On non-Unix, non-Linux platforms, the collector is usually built by copying
+the appropriate makefile (see the platform-specific README in doc/README.xxx
+in the distribution) to the file "Makefile" (overwriting the copy of
+Makefile.direct that was originally there), and then typing "make"
+(or "nmake" or ...).  This builds the library in the source tree.  You may
+want to move it and the files in the include directory to a more convenient
+place.
+</font>
+<P>
+<FONT COLOR=green>
+If you use a makefile that does not require running a configure script,
+you should first look at the makefile, and adjust any options that are
+documented there.
+</font>
+<P>
+<FONT COLOR=green>
+If your platform provides a "make" utility, that is generally preferred
+to platform- and compiler- dependent "project" files.  (At least that is the
+strong preference of the would-be maintainer of those project files.)
+</font>
+<H3><FONT COLOR=green>Threads</font></h3>
+<FONT COLOR=green>
+If you need thread support, configure the collector with
+</font>
+<PRE style="color:green">
+--enable-threads=posix --enable-thread-local-alloc --enable-parallel-mark
+</pre>
+<FONT COLOR=green>
+instead of
+<TT>--disable-threads</tt>
+If your target is a real old-fashioned uniprocessor (no "hyperthreading",
+etc.) you will want to omit <TT>--enable-parallel-mark</tt>.
+</font>
+<H3><FONT COLOR=green>C++</font></h3>
+<FONT COLOR=green>
+You will need to include the C++ support, which unfortunately tends to
+be among the least portable parts of the collector, since it seems
+to rely on some corner cases of the language.  On Linux, it
+suffices to add <TT>--enable-cplusplus</tt> to the configure options.
+</font>
+<H2>Writing the program</h2>
+You will need a
+<PRE>
+#include "gc.h"
+</pre>
+at the beginning of every file that allocates memory through the
+garbage collector.  Call <TT>GC_MALLOC</tt> wherever you would
+have call <TT>malloc</tt>.  This initializes memory to zero like
+<TT>calloc</tt>; there is no need to explicitly clear the
+result.
+<P>
+If you know that an object will not contain pointers to the
+garbage-collected heap, and you don't need it to be initialized,
+call <TT>GC_MALLOC_ATOMIC</tt> instead.
+<P>
+A function <TT>GC_FREE</tt> is provided but need not be called.
+For very small objects, your program will probably perform better if
+you do not call it, and let the collector do its job.
+<P>
+A <TT>GC_REALLOC</tt> function behaves like the C library <TT>realloc</tt>.
+It allocates uninitialized pointer-free memory if the original
+object was allocated that way.
+<P>
+The following program <TT>loop.c</tt> is a trivial example:
+<PRE>
+#include "gc.h"
+#include &lt;assert.h&gt;
+#include &lt;stdio.h&gt;
+
+int main()
+{
+  int i;
+
+  GC_INIT();   /* Optional on Linux/X86; see below.  */
+  for (i = 0; i &lt; 10000000; ++i)
+   {
+     int **p = (int **) GC_MALLOC(sizeof(int *));
+     int *q = (int *) GC_MALLOC_ATOMIC(sizeof(int));
+     assert(*p == 0);
+     *p = (int *) GC_REALLOC(q, 2 * sizeof(int));
+     if (i % 100000 == 0)
+       printf("Heap size = %d\n", GC_get_heap_size());
+   }
+  return 0;
+}
+</pre>
+<H3><FONT COLOR=green>Interaction with the system malloc</font></h3>
+<FONT COLOR=green>
+It is usually best not to mix garbage-collected allocation with the system
+<TT>malloc-free</tt>.  If you do, you need to be careful not to store
+pointers to the garbage-collected heap in memory allocated with the system
+<TT>malloc</tt>.
+</font>
+
+<H3><FONT COLOR=green>Other Platforms</font></h3>
+<FONT COLOR=green>
+On some other platforms it is necessary to call <TT>GC_INIT()</tt> from the main program,
+which is presumed to be part of the main executable, not a dynamic library.
+This can never hurt, and is thus generally good practice.
+</font>
+
+<H3><FONT COLOR=green>Threads</font></h3>
+<FONT COLOR=green>
+For a multithreaded program some more rules apply:
+</font>
+<UL>
+<LI>
+<FONT COLOR=green>
+Files that either allocate through the GC <I>or make thread-related calls</i>
+should first define the macro <TT>GC_THREADS</tt>, and then
+include <TT>"gc.h"</tt>.  On some platforms this will redefine some
+threads primitives, e.g. to let the collector keep track of thread creation.
+</font>
+<LI>
+<FONT COLOR=green>
+To take advantage of fast thread-local allocation in versions before 7.0,
+use the following instead
+of including <TT>gc.h</tt>:
+</font>
+<PRE style="color:green">
+#define GC_REDIRECT_TO_LOCAL
+#include "gc_local_alloc.h"
+</pre>
+<FONT COLOR=green>
+This will cause GC_MALLOC and GC_MALLOC_ATOMIC to keep per-thread allocation
+caches, and greatly reduce the number of lock acquisitions during allocation.
+For versions after 7.0, this happens implicitly if the collector is built
+with thread-local allocation enabled.
+</font>
+</ul>
+
+<H3><FONT COLOR=green>C++</font></h3>
+<FONT COLOR=green>
+In the case of C++, you need to be especially careful not to store pointers
+to the garbage-collected heap in areas that are not traced by the collector.
+The collector includes some <A HREF="gcinterface.html">alternate interfaces</a>
+to make that easier.
+</font>
+
+<H3><FONT COLOR=green>Debugging</font></h3>
+<FONT COLOR=green>

+You may be able to build the collector with <TT>--enable-redirect-malloc</tt>
+and set the <TT>LD_PRELOAD</tt> environment variable to point to the resulting
+library, thus replacing the standard <TT>malloc</tt> with its garbage-collected

+
+<H2>Compiling and linking</h2>
+
+The above application <TT>loop.c</tt> test program can be compiled and linked
+with
+
+<PRE>
+cc -I/home/xyz/gc/include loop.c /home/xyz/gc/lib/libgc.a -o loop
+</pre>
+
+The <TT>-I</tt> option directs the compiler to the right include
+directory.  In this case, we list the static library
+directly on the compile line; the dynamic library could have been
+used instead, provided we arranged for the dynamic loader to find
+it, e.g. by setting <TT>LD_LIBRARY_PATH</tt>.

+On pthread platforms, you will of course also have to link with
+<TT>-lpthread</tt>,
+and compile with any thread-safety options required by your compiler.
+On some platforms, you may also need to link with <TT>-ldl</tt>
+or <TT>-lrt</tt>.
+Looking at threadlibs.c in the GC "extra" directory
+should give you the appropriate
+list if a plain <TT>-lpthread</tt> doesn't work.

+
+<H2>Running the executable</h2>
+
+The executable can of course be run normally, e.g. by typing

+
+The operation of the collector is affected by a number of environment variables.

+</HEAD>
+<BODY>
+<H1>Two-Level Tree Structure for Fast Pointer Lookup</h1>
+<P>
+The conservative garbage collector described
+<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/">here</a>
+uses a 2-level tree
+data structure to aid in fast pointer identification.
+This data structure is described in a bit more detail here, since
+<OL>
+<LI> Variations of the data structure are more generally useful.
+<LI> It appears to be hard to understand by reading the code.
+<LI> Some other collectors appear to use inferior data structures to
+solve the same problem.
+<LI> It is central to fast collector operation.
+</ol>
+A candidate pointer is divided into three sections, the <I>high</i>,
+<I>middle</i>, and <I>low</i> bits.  The exact division between these
+three groups of bits is dependent on the detailed collector configuration.
+<P>
+The high and middle bits are used to look up an entry in the table described
+here.  The resulting table entry consists of either a block descriptor
+(<TT>struct hblkhdr *</tt> or <TT>hdr *</tt>)
+identifying the layout of objects in the block, or an indication that this
+address range corresponds to the middle of a large block, together with a
+hint for locating the actual block descriptor.  Such a hint consist
+of a displacement that can be subtracted from the middle bits of the candidate
+pointer without leaving the object.
+<P>
+In either case, the block descriptor (<TT>struct hblkhdr</tt>)
+refers to a table of object starting addresses (the <TT>hb_map</tt> field).
+The starting address table is indexed by the low bits if the candidate pointer.
+The resulting entry contains a displacement to the beginning of the object,
+or an indication that this cannot be a valid object pointer.
+(If all interior pointer are recognized, pointers into large objects
+are handled specially, as appropriate.)
+
+<H2>The Tree</h2>
+<P>
+The rest of this discussion focuses on the two level data structure
+used to map the high and middle bits to the block descriptor.
+<P>
+The high bits are used as an index into the <TT>GC_top_index</tt> (really
+<TT>GC_arrays._top_index</tt>) array.  Each entry points to a
+<TT>bottom_index</tt> data structure.  This structure in turn consists
+mostly of an array <TT>index</tt> indexed by the middle bits of
+the candidate pointer.  The <TT>index</tt> array contains the actual
+<TT>hdr</tt> pointers. 
+<P>
+Thus a pointer lookup consists primarily of a handful of memory references,
+and can be quite fast:
+<OL>
+<LI> The appropriate <TT>bottom_index</tt> pointer is looked up in
+<TT>GC_top_index</tt>, based on the high bits of the candidate pointer.
+<LI> The appropriate <TT>hdr</tt> pointer is looked up in the
+<TT>bottom_index</tt> structure, based on the middle bits.
+<LI> The block layout map pointer is retrieved from the <TT>hdr</tt>
+structure.  (This memory reference is necessary since we try to share
+block layout maps.)
+<LI> The displacement to the beginning of the object is retrieved from the
+above map.
+</ol>
+<P>
+In order to conserve space, not all <TT>GC_top_index</tt> entries in fact
+point to distinct <TT>bottom_index</tt> structures.  If no address with
+the corresponding high bits is part of the heap, then the entry points
+to <TT>GC_all_nils</tt>, a single <TT>bottom_index</tt> structure consisting
+only of NULL <TT>hdr</tt> pointers.
+<P>
+<TT>Bottom_index</tt> structures contain slightly more information than
+just <TT>hdr</tt> pointers.  The <TT>asc_link</tt> field is used to link
+all <TT>bottom_index</tt> structures in ascending order for fast traversal.
+This list is pointed to be <TT>GC_all_bottom_indices</tt>.
+It is maintained with the aid of <TT>key</tt> field that contains the
+high bits corresponding to the <TT>bottom_index</tt>.
+
+<H2>64 bit addresses</h2>
+<P>
+In the case of 64 bit addresses, this picture is complicated slightly
+by the fact that one of the index structures would have to be huge to
+cover the entire address space with a two level tree.  We deal with this
+by turning <TT>GC_top_index</tt> into a chained hash table, instead of
+a simple array.  This adds a <TT>hash_link</tt> field to the
+<TT>bottom_index</tt> structure.
+<P>
+The "hash function" consists of dropping the high bits.  This is cheap to
+compute, and guarantees that there will be no collisions if the heap
+is contiguous and not excessively large.
+
+<H2>A picture</h2>
+<P>
+The following is an ASCII diagram of the data structure.
+This was contributed by Dave Barrett several years ago.

+ * Cords are immutable character strings.  A number of operations
+ * on long cords are much more efficient than their strings.h counterpart.
+ * In particular, concatenation takes constant time independent of the length
+ * of the arguments.  (Cords are represented as trees, with internal
+ * nodes representing concatenation and leaves consisting of either C
+ * strings or a functional description of the string.)
+ *
+ * The following are reasonable applications of cords.  They would perform
+ * unacceptably if C strings were used:
+ * - A compiler that produces assembly language output by repeatedly
+ *   concatenating instructions onto a cord representing the output file.
+ * - A text editor that converts the input file to a cord, and then
+ *   performs editing operations by producing a new cord representing
+ *   the file after each character change (and keeping the old ones in an
+ *   edit history)
+ *
+ * For optimal performance, cords should be built by
+ * concatenating short sections.
+ * This interface is designed for maximum compatibility with C strings.
+ * ASCII NUL characters may be embedded in cords using CORD_from_fn.
+ * This is handled correctly, but CORD_to_char_star will produce a string
+ * with embedded NULs when given such a cord.
+ *
+ * This interface is fairly big, largely for performance reasons.
+ * The most basic constants and functions:
+ *
+ * CORD - the type of a cord;
+ * CORD_EMPTY - empty cord;
+ * CORD_len(cord) - length of a cord;
+ * CORD_cat(cord1,cord2) - concatenation of two cords;
+ * CORD_substr(cord, start, len) - substring (or subcord);
+ * CORD_pos i;  CORD_FOR(i, cord) {  ... CORD_pos_fetch(i) ... } -
+ *    examine each character in a cord.  CORD_pos_fetch(i) is the char.
+ * CORD_fetch(int i) - Retrieve i'th character (slowly).
+ * CORD_cmp(cord1, cord2) - compare two cords.
+ * CORD_from_file(FILE * f) - turn a read-only file into a cord.
+ * CORD_to_char_star(cord) - convert to C string.
+ *   (Non-NULL C constant strings are cords.)
+ * CORD_printf (etc.) - cord version of printf. Use %r for cords.

+C++ Interface to the Boehm Collector
+
+    John R. Ellis and Jesse Hull
+
+This interface provides access to the Boehm collector.  It provides
+basic facilities similar to those described in "Safe, Efficient
+Garbage Collection for C++", by John R. Elis and David L. Detlefs
+(ftp://ftp.parc.xerox.com/pub/ellis/gc).
+
+All heap-allocated objects are either "collectable" or
+"uncollectable".  Programs must explicitly delete uncollectable
+objects, whereas the garbage collector will automatically delete
+collectable objects when it discovers them to be inaccessible.
+Collectable objects may freely point at uncollectable objects and vice
+versa.
+
+Objects allocated with the built-in "::operator new" are uncollectable.
+
+Objects derived from class "gc" are collectable.  For example:
+
+    class A: public gc {...};
+    A* a = new A;       // a is collectable.
+
+Collectable instances of non-class types can be allocated using the GC
+(or UseGC) placement:
+
+    typedef int A[ 10 ];
+    A* a = new (GC) A;
+
+Uncollectable instances of classes derived from "gc" can be allocated
+using the NoGC placement:
+
+    class A: public gc {...};
+    A* a = new (NoGC) A;   // a is uncollectable.
+
+The new(PointerFreeGC) syntax allows the allocation of collectable
+objects that are not scanned by the collector.  This useful if you
+are allocating compressed data, bitmaps, or network packets.  (In
+the latter case, it may remove danger of unfriendly network packets
+intentionally containing values that cause spurious memory retention.)
+
+Both uncollectable and collectable objects can be explicitly deleted
+with "delete", which invokes an object's destructors and frees its
+storage immediately.
+
+A collectable object may have a clean-up function, which will be
+invoked when the collector discovers the object to be inaccessible.
+An object derived from "gc_cleanup" or containing a member derived
+from "gc_cleanup" has a default clean-up function that invokes the
+object's destructors.  Explicit clean-up functions may be specified as
+an additional placement argument:
+
+    A* a = ::new (GC, MyCleanup) A;
+
+An object is considered "accessible" by the collector if it can be
+reached by a path of pointers from static variables, automatic
+variables of active functions, or from some object with clean-up
+enabled; pointers from an object to itself are ignored.
+
+Thus, if objects A and B both have clean-up functions, and A points at
+B, B is considered accessible.  After A's clean-up is invoked and its
+storage released, B will then become inaccessible and will have its
+clean-up invoked.  If A points at B and B points to A, forming a
+cycle, then that's considered a storage leak, and neither will be
+collectable.  See the interface gc.h for low-level facilities for
+handling such cycles of objects with clean-up.
+
+The collector cannot guarantee that it will find all inaccessible
+objects.  In practice, it finds almost all of them.
+
+
+Cautions:
+
+1. Be sure the collector has been augmented with "make c++" or
+"--enable-cplusplus".
+
+2.  If your compiler supports the new "operator new[]" syntax, then
+add -DGC_OPERATOR_NEW_ARRAY to the Makefile.
+
+If your compiler doesn't support "operator new[]", beware that an
+array of type T, where T is derived from "gc", may or may not be
+allocated as a collectable object (it depends on the compiler).  Use
+the explicit GC placement to make the array collectable.  For example:
+
+    class A: public gc {...};
+    A* a1 = new A[ 10 ];        // collectable or uncollectable?
+    A* a2 = new (GC) A[ 10 ];   // collectable
+
+3. The destructors of collectable arrays of objects derived from
+"gc_cleanup" will not be invoked properly.  For example:
+
+    class A: public gc_cleanup {...};
+    A* a = new (GC) A[ 10 ];    // destructors not invoked correctly
+
+Typically, only the destructor for the first element of the array will
+be invoked when the array is garbage-collected.  To get all the
+destructors of any array executed, you must supply an explicit
+clean-up function:
+
+    A* a = new (GC, MyCleanUp) A[ 10 ];
+
+(Implementing clean-up of arrays correctly, portably, and in a way
+that preserves the correct exception semantics requires a language
+extension, e.g. the "gc" keyword.)
+
+4. Compiler bugs (now hopefully history):
+
+* Solaris 2's CC (SC3.0) doesn't implement t->~T() correctly, so the
+destructors of classes derived from gc_cleanup won't be invoked.
+You'll have to explicitly register a clean-up function with
+new-placement syntax.
+
+* Evidently cfront 3.0 does not allow destructors to be explicitly
+invoked using the ANSI-conforming syntax t->~T().  If you're using
+cfront 3.0, you'll have to comment out the class gc_cleanup, which
+uses explicit invocation.
+
+5. GC name conflicts:
+
+Many other systems seem to use the identifier "GC" as an abbreviation
+for "Graphics Context".  Since version 5.0, GC placement has been replaced
+by UseGC.  GC is an alias for UseGC, unless GC_NAME_CONFLICT is defined.

+ * For each architecture and OS, the following need to be defined:

+ * CPP_WORDSZ is a simple integer constant representing the word size.
+ * in bits.  We assume byte addressability, where a byte has 8 bits.
+ * We also assume CPP_WORDSZ is either 32 or 64.
+ * (We care about the length of pointers, not hardware
+ * bus widths.  Thus a 64 bit processor with a C compiler that uses
+ * 32 bit pointers should use CPP_WORDSZ of 32, not 64. Default is 32.)
+ *
+ * MACH_TYPE is a string representation of the machine type.
+ * OS_TYPE is analogous for the OS.
+ *
+ * ALIGNMENT is the largest N, such that
+ * all pointer are guaranteed to be aligned on N byte boundaries.
+ * defining it to be 1 will always work, but perform poorly.
+ *
+ * DATASTART is the beginning of the data segment.
+ * On some platforms SEARCH_FOR_DATA_START is defined.
+ * SEARCH_FOR_DATASTART will cause GC_data_start to
+ * be set to an address determined by accessing data backwards from _end
+ * until an unmapped page is found.  DATASTART will be defined to be
+ * GC_data_start.
+ * On UNIX-like systems, the collector will scan the area between DATASTART
+ * and DATAEND for root pointers.
+ *
+ * DATAEND, if not `end' where `end' is defined as ``extern int end[];''.
+ * RTH suggests gaining access to linker script synth'd values with
+ * this idiom instead of `&end' where `end' is defined as ``extern int end;'' .
+ * Otherwise, ``GCC will assume these are in .sdata/.sbss'' and it will, e.g.,
+ * cause failures on alpha*-*-* with ``-msmall-data or -fpic'' or mips-*-*
+ * without any special options.
+ *
+ * STACKBOTTOM is the cool end of the stack, which is usually the
+ * highest address in the stack.
+ * Under PCR or OS/2, we have other ways of finding thread stacks.
+ * For each machine, the following should:
+ * 1) define STACK_GROWS_UP if the stack grows toward higher addresses, and
+ * 2) define exactly one of
+ *      STACKBOTTOM (should be defined to be an expression)
+ *      LINUX_STACKBOTTOM
+ *      HEURISTIC1
+ *      HEURISTIC2
+ * If STACKBOTTOM is defined, then it's value will be used directly as the
+ * stack base.  If LINUX_STACKBOTTOM is defined, then it will be determined
+ * with a method appropriate for most Linux systems.  Currently we look
+ * first for __libc_stack_end (currently only if USE_LIBC_PRIVATES is
+ * defined), and if that fails read it from /proc.  (If USE_LIBC_PRIVATES
+ * is not defined and NO_PROC_STAT is defined, we revert to HEURISTIC2.)
+ * If either of the last two macros are defined, then STACKBOTTOM is computed
+ * during collector startup using one of the following two heuristics:
+ * HEURISTIC1:  Take an address inside GC_init's frame, and round it up to
+ *              the next multiple of STACK_GRAN.
+ * HEURISTIC2:  Take an address inside GC_init's frame, increment it repeatedly
+ *              in small steps (decrement if STACK_GROWS_UP), and read the value
+ *              at each location.  Remember the value when the first
+ *              Segmentation violation or Bus error is signaled.  Round that
+ *              to the nearest plausible page boundary, and use that instead
+ *              of STACKBOTTOM.
+ *
+ * Gustavo Rodriguez-Rivera points out that on most (all?) Unix machines,
+ * the value of environ is a pointer that can serve as STACKBOTTOM.
+ * I expect that HEURISTIC2 can be replaced by this approach, which
+ * interferes far less with debugging.  However it has the disadvantage
+ * that it's confused by a putenv call before the collector is initialized.
+ * This could be dealt with by intercepting putenv ...
+ *
+ * If no expression for STACKBOTTOM can be found, and neither of the above
+ * heuristics are usable, the collector can still be used with all of the above
+ * undefined, provided one of the following is done:
+ * 1) GC_mark_roots can be changed to somehow mark from the correct stack(s)
+ *    without reference to STACKBOTTOM.  This is appropriate for use in
+ *    conjunction with thread packages, since there will be multiple stacks.
+ *    (Allocating thread stacks in the heap, and treating them as ordinary
+ *    heap data objects is also possible as a last resort.  However, this is
+ *    likely to introduce significant amounts of excess storage retention
+ *    unless the dead parts of the thread stacks are periodically cleared.)
+ * 2) Client code may set GC_stackbottom before calling any GC_ routines.
+ *    If the author of the client code controls the main program, this is
+ *    easily accomplished by introducing a new main program, setting
+ *    GC_stackbottom to the address of a local variable, and then calling
+ *    the original main program.  The new main program would read something
+ *    like (provided real_main() is not inlined by the compiler):
+ *
+ *              # include "gc_private.h"
+ *
+ *              main(argc, argv, envp)
+ *              int argc;
+ *              char **argv, **envp;
+ *              {
+ *                  int dummy;
+ *
+ *                  GC_stackbottom = (ptr_t)(&dummy);
+ *                  return(real_main(argc, argv, envp));
+ *              }
+ *
+ *
+ * Each architecture may also define the style of virtual dirty bit
+ * implementation to be used:
+ *   MPROTECT_VDB: Write protect the heap and catch faults.
+ *   GWW_VDB: Use win32 GetWriteWatch primitive.
+ *   PROC_VDB: Use the SVR4 /proc primitives to read dirty bits.
+ *
+ * The first and second one may be combined, in which case a runtime
+ * selection will be made, based on GetWriteWatch availability.
+ *
+ * An architecture may define DYNAMIC_LOADING if dyn_load.c
+ * defined GC_register_dynamic_libraries() for the architecture.
+ *
+ * An architecture may define PREFETCH(x) to preload the cache with *x.
+ * This defaults to a no-op.
+ *
+ * PREFETCH_FOR_WRITE(x) is used if *x is about to be written.
+ *
+ * An architecture may also define CLEAR_DOUBLE(x) to be a fast way to
+ * clear the two words at GC_malloc-aligned address x.  By default,
+ * word stores of 0 are used instead.
+ *
+ * HEAP_START may be defined as the initial address hint for mmap-based
+ * allocation.

+
+CleanUp
+
+A garbage-collected object can have an associated clean-up function
+that will be invoked some time after the collector discovers the
+object is unreachable via normal pointers. Clean-up functions can be
+used to release resources such as open-file handles or window handles
+when their containing objects become unreachable.  If a C++ object has
+a non-empty explicit destructor (i.e. it contains programmer-written
+code), the destructor will be automatically registered as the object's
+initial clean-up function.
+
+There is no guarantee that the collector will detect every unreachable
+object (though it will find almost all of them). Clients should not
+rely on clean-up to cause some action to occur immediately -- clean-up
+is only a mechanism for improving resource usage.
+
+Every object with a clean-up function also has a clean-up queue. When
+the collector finds the object is unreachable, it enqueues it on its
+queue. The clean-up function is applied when the object is removed
+from the queue. By default, objects are enqueued on the garbage
+collector's queue, and the collector removes all objects from its
+queue after each collection. If a client supplies another queue for
+objects, it is his responsibility to remove objects (and cause their
+functions to be called) by polling it periodically.
+
+Clean-up queues allow clean-up functions accessing global data to
+synchronize with the main program. Garbage collection can occur at any
+time, and clean-ups invoked by the collector might access data in an
+inconsistent state. A client can control this by defining an explicit
+queue for objects and polling it at safe points.
+
+The following definitions are used by the specification below:
+
+Given a pointer t to a collected object, the base object BO(t) is the
+value returned by new when it created the object. (Because of multiple
+inheritance, t and BO(t) may not be the same address.)
+
+A weak pointer wp references an object *t if BO(wp.Pointer()) ==
+BO(t).

+
+Reachability and Clean-up
+
+An object O is reachable if it can be reached via a non-empty path of
+normal pointers from the registers, stacks, global variables, or an
+object with a non-null clean-up function (including O itself),
+ignoring pointers from an object to itself.
+
+This definition of reachability ensures that if object B is accessible
+from object A (and not vice versa) and if both A and B have clean-up
+functions, then A will always be cleaned up before B. Note that as
+long as an object with a clean-up function is contained in a cycle of
+pointers, it will always be reachable and will never be cleaned up or
+collected.
+
+When the collector finds an unreachable object with a null clean-up
+function, it atomically deactivates all weak pointers referencing the
+object and recycles its storage. If object B is accessible from object
+A via a path of normal pointers, A will be discovered unreachable no
+later than B, and a weak pointer to A will be deactivated no later
+than a weak pointer to B.
+
+When the collector finds an unreachable object with a non-null
+clean-up function, the collector atomically deactivates all weak
+pointers referencing the object, redefines its clean-up function to be
+null, and enqueues it on its clean-up queue. The object then becomes
+reachable again and remains reachable at least until its clean-up
+function executes.
+
+The clean-up function is assured that its argument is the only
+accessible pointer to the object. Nothing prevents the function from
+redefining the object's clean-up function or making the object
+reachable again (for example, by storing the pointer in a global
+variable).
+
+If the clean-up function does not make its object reachable again and
+does not redefine its clean-up function, then the object will be
+collected by a subsequent collection (because the object remains
+unreachable and now has a null clean-up function). If the clean-up
+function does make its object reachable again and a clean-up function
+is subsequently redefined for the object, then the new clean-up
+function will be invoked the next time the collector finds the object
+unreachable.
+
+Note that a destructor for a collected object cannot safely redefine a
+clean-up function for its object, since after the destructor executes,
+the object has been destroyed into "raw memory". (In most
+implementations, destroying an object mutates its vtbl.)
+
+Finally, note that calling delete t on a collected object first
+deactivates any weak pointers to t and then invokes its clean-up
+function (destructor).

+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                    END OF TERMS AND CONDITIONS
+\f
+           How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+This General Public License does not permit incorporating your program into

+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+Synopsis
+========
+
+This package provides semi-portable access to hardware provided
+atomic memory operations.  These might allow you to write code:
+
+- That does more interesting things in signal handlers.
+- Makes more effective use of multiprocessors by allowing you to write
+  clever lock-free code.  Note that such code is very difficult to get
+  right, and will unavoidably be less portable than lock-based code.  It
+  is also not always faster than lock-based code.  But it may occasionally
+  be a large performance win.
+- To experiment with new and much better thread programming paradigms, etc.
+
+For details and licensing restrictions see the files in the doc
+subdirectory.
+
+This is version 7.2d of libatomic_ops.
+
+You might find a more recent version of this at
+
+http://www.hpl.hp.com/personal/Hans_Boehm/gc
+
+or

+
+
+Installation and Usage
+======================
+
+The configuration and build scripts for this package were generated by
+Automake/Autoconf.  "./configure --prefix=<install dir>; make; make install"
+in this directory should work.  For a more customized build, see "INSTALL"
+and the output of "./configure --help".
+
+Note that much of the content of this library is in the header files.
+However, two small libraries are built and installed:
+
+- libatomic_ops.a is a support library, which is not needed on some platforms.
+  This is intended to be usable, under some mild restrictions, in free or
+  proprietary code, as are all the header files.  See doc/LICENSING.txt.
+- libatomic_ops_gpl.a contains some higher level facilities.  This code is
+  currently covered by the GPL.  The contents currently correspond to
+  the headers atomic_ops_stack.h and atomic_ops_malloc.h.
+
+
+Platform Specific Notes
+=======================
+
+Win32/64: src/Makefile.msft contains a very simple Makefile for building
+and running tests and building the gpl library.  The core atomic_ops
+implementation is entirely in header files.
+
+HP-UX/PA-RISC: aCC -Ae won't work as a C compiler, since it doesn't support
+inline assembly code.  Use cc.

+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+   Here is a matrix of mmap possibilities:
+       mmap private not fixed
+       mmap private fixed at somewhere currently unmapped
+       mmap private fixed at somewhere already mapped
+       mmap shared not fixed
+       mmap shared fixed at somewhere currently unmapped
+       mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                    END OF TERMS AND CONDITIONS
+\f
+           How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:

+Our intent is to make it easy to use libatomic_ops, in
+both free and proprietary software.  Hence most code that we expect to be
+linked into a client application is covered by an MIT-style license.
+
+A few library routines are covered by the GNU General Public License.
+These are put into a separate library, libatomic_ops_gpl.a .
+
+The low-level part of the library is mostly covered by the following

+Usage:
+
+0) If possible, do this on a multiprocessor, especially if you are planning
+on modifying or enhancing the package.  It will work on a uniprocessor,
+but the tests are much more likely to pass in the presence of serious problems.
+
+1) Type ./configure --prefix=<install dir>; make; make check
+in the directory containing unpacked source.  The usual GNU build machinery
+is used, except that only static, but position-independent, libraries
+are normally built.  On Windows, read README_win32.txt instead.
+
+2) Applications should include atomic_ops.h.  Nearly all operations
+are implemented by header files included from it.  It is sometimes
+necessary, and always recommended to also link against libatomic_ops.a.
+To use the almost non-blocking stack or malloc implementations,
+see the corresponding README files, and also link against libatomic_gpl.a
+before linking against libatomic_ops.a.
+
+OVERVIEW:
+Atomic_ops.h defines a large collection of operations, each one of which is
+a combination of an (optional) atomic memory operation, and a memory barrier.
+Also defines associated feature-test macros to determine whether a particular
+operation is available on the current target hardware (either directly or
+by synthesis).  This is an attempt to replace various existing files with
+similar goals, since they usually do not handle differences in memory
+barrier styles with sufficient generality.
+
+If this is included after defining AO_REQUIRE_CAS, then the package
+will make an attempt to emulate compare-and-swap in a way that (at least
+on Linux) should still be async-signal-safe.  As a result, most other
+atomic operations will then be defined using the compare-and-swap
+emulation.  This emulation is slow, since it needs to disable signals.
+And it needs to block in case of contention.  If you care about performance
+on a platform that can't directly provide compare-and-swap, there are
+probably better alternatives.  But this allows easy ports to some such
+platforms (e.g. PA_RISC).  The option is ignored if compare-and-swap
+can be implemented directly.
+
+If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all
+atomic operations will be emulated with pthread locking.  This is NOT
+async-signal-safe.  And it is slow.  It is intended primarily for debugging
+of the atomic_ops package itself.
+
+Note that the implementation reflects our understanding of real processor
+behavior.  This occasionally diverges from the documented behavior.  (E.g.
+the documented X86 behavior seems to be weak enough that it is impractical
+to use.  Current real implementations appear to be much better behaved.)
+We of course are in no position to guarantee that future processors
+(even HPs) will continue to behave this way, though we hope they will.
+
+This is a work in progress.  Corrections/additions for other platforms are
+greatly appreciated.  It passes rudimentary tests on X86, Itanium, and
+Alpha.
+
+OPERATIONS:
+
+Most operations operate on values of type AO_t, which are unsigned integers
+whose size matches that of pointers on the given architecture.  Exceptions
+are:
+
+- AO_test_and_set operates on AO_TS_t, which is whatever size the hardware
+supports with good performance.  In some cases this is the length of a cache
+line.  In some cases it is a byte.  In many cases it is equivalent to AO_t.
+
+- A few operations are implemented on smaller or larger size integers.
+Such operations are indicated by the appropriate prefix:
+
+AO_char_... Operates on unsigned char values.
+AO_short_... Operates on unsigned short values.
+AO_int_... Operates on unsigned int values.
+
+(Currently a very limited selection of these is implemented.  We're
+working on it.)
+
+The defined operations are all of the form AO_[<size>_]<op><barrier>(<args>).
+
+The <op> component specifies an atomic memory operation.  It may be
+one of the following, where the corresponding argument and result types
+are also specified:
+
+void nop()
+        No atomic operation.  The barrier may still be useful.
+AO_t load(const volatile AO_t * addr)
+        Atomic load of *addr.
+void store(volatile AO_t * addr, AO_t new_val)
+        Atomically store new_val to *addr.
+AO_t fetch_and_add(volatile AO_t *addr, AO_t incr)
+        Atomically add incr to *addr, and return the original value of *addr.
+AO_t fetch_and_add1(volatile AO_t *addr)
+        Equivalent to AO_fetch_and_add(addr, 1).
+AO_t fetch_and_sub1(volatile AO_t *addr)
+        Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)).
+void or(volatile AO_t *addr, AO_t incr)
+        Atomically or incr into *addr.
+int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val)
+        Atomically compare *addr to old_val, and replace *addr by new_val
+        if the first comparison succeeds.  Returns nonzero if the comparison
+        succeeded and *addr was updated.
+AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr)
+        Atomically read the binary value at *addr, and set it.  AO_TS_VAL_t
+        is an enumeration type which includes two values AO_TS_SET and
+        AO_TS_CLEAR.  An AO_TS_t location is capable of holding an
+        AO_TS_VAL_t, but may be much larger, as dictated by hardware
+        constraints.  Test_and_set logically sets the value to AO_TS_SET.
+        It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro.
+        AO_TS_t locations should be initialized to AO_TS_INITIALIZER.
+        The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent.
+        (On PA-RISC, AO_TS_SET is zero!)
+
+Test_and_set is a more limited version of compare_and_swap.  Its only
+advantage is that it is more easily implementable on some hardware.  It
+should thus be used if only binary test-and-set functionality is needed.
+
+If available, we also provide compare_and_swap operations that operate
+on wider values.  Since standard data types for double width values
+may not be available, these explicitly take pairs of arguments for the
+new and/or old value.  Unfortunately, there are two common variants,
+neither of which can easily and efficiently emulate the other.
+The first performs a comparison against the entire value being replaced,
+where the second replaces a double-width replacement, but performs
+a single-width comparison:
+
+int compare_double_and_swap_double(volatile AO_double_t * addr,
+                                   AO_t old_val1, AO_t old_val2,
+                                   AO_t new_val1, AO_t new_val2);
+
+int compare_and_swap_double(volatile AO_double_t * addr,
+                            AO_t old_val1,
+                            AO_t new_val1, AO_t new_val2);
+
+where AO_double_t is a structure containing AO_val1 and AO_val2 fields,
+both of type AO_t.  For compare_and_swap_double, we compare against
+the val1 field.  AO_double_t exists only if AO_HAVE_double_t
+is defined.
+
+ORDERING CONSTRAINTS:
+
+Each operation name also includes a suffix that specifies the associated
+ordering semantics.  The ordering constraint limits reordering of this
+operation with respect to other atomic operations and ordinary memory
+references.  The current implementation assumes that all memory references
+are to ordinary cacheable memory; the ordering guarantee is with respect
+to other threads or processes, not I/O devices.  (Whether or not this
+distinction is important is platform-dependent.)
+
+Ordering suffixes are one of the following:
+
+<none>: No memory barrier.  A plain AO_nop() really does nothing.
+_release: Earlier operations must become visible to other threads
+          before the atomic operation.
+_acquire: Later operations must become visible after this operation.
+_read: Subsequent reads must become visible after reads included in
+       the atomic operation or preceding it.  Rarely useful for clients?
+_write: Earlier writes become visible before writes during or after
+        the atomic operation.  Rarely useful for clients?
+_full: Ordered with respect to both earlier and later memory ops.
+       AO_store_full or AO_nop_full are the normal ways to force a store
+       to be ordered with respect to a later load.
+_release_write: Ordered with respect to earlier writes.  This is
+                normally implemented as either a _write or _release
+                barrier.
+_dd_acquire_read: Ordered with respect to later reads that are data
+               dependent on this one.  This is needed on
+               a pointer read, which is later dereferenced to read a
+               second value, with the expectation that the second
+               read is ordered after the first one.  On most architectures,
+               this is equivalent to no barrier.  (This is very
+               hard to define precisely.  It should probably be avoided.
+               A major problem is that optimizers tend to try to
+               eliminate dependencies from the generated code, since
+               dependencies force the hardware to execute the code
+               serially.)
+_release_read: Ordered with respect to earlier reads.  Useful for
+               implementing read locks.  Can be implemented as _release,
+               but not as _read, since _read groups the current operation
+               with the earlier ones.
+
+We assume that if a store is data-dependent on an a previous load, then
+the two are always implicitly ordered.
+
+It is possible to test whether AO_<op><barrier> is available on the
+current platform by checking whether AO_HAVE_<op>_<barrier> is defined
+as a macro.
+
+Note that we generally don't implement operations that are either
+meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to
+have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write,
+AO_store_read).  On some platforms (e.g. PA-RISC) many operations
+will remain undefined unless AO_REQUIRE_CAS is defined before including
+the package.
+
+When typed in the package build directory, the following command
+will print operations that are unimplemented on the platform:
+
+make test_atomic; ./test_atomic
+
+The following command generates a file "list_atomic.i" containing the
+macro expansions of all implemented operations on the platform:
+
+make list_atomic.i
+
+Future directions:
+
+It currently appears that something roughly analogous to this is very likely
+to become part of the C++0x standard.  That effort has pointed out a number
+of issues that we expect to address there.  Since some of the solutions
+really require compiler support, they may not be completely addressed here.
+
+Known issues include:
+
+We should be more precise in defining the semantics of the ordering
+constraints, and if and how we can guarantee sequential consistency.
+
+Dd_acquire_read is very hard or impossible to define in a way that cannot
+be invalidated by reasonably standard compiler transformations.
+
+There is probably no good reason to provide operations on standard
+integer types, since those may have the wrong alignment constraints.
+
+
+Example:
+
+If you want to initialize an object, and then "publish" a pointer to it
+in a global location p, such that other threads reading the new value of
+p are guaranteed to see an initialized object, it suffices to use
+AO_release_write(p, ...) to write the pointer to the object, and to
+retrieve it in other threads with AO_acquire_read(p).
+
+Platform notes:
+
+All X86: We quietly assume 486 or better.
+
+Microsoft compilers:
+Define AO_ASSUME_WINDOWS98 to get access to hardware compare-and-swap
+functionality.  This relies on the InterlockedCompareExchange() function
+which was apparently not supported in Windows95.  (There may be a better
+way to get access to this.)
+
+Gcc on x86:
+Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction.
+Currently this is appears to be of marginal benefit.

+The libatomic_ops_gpl includes a simple almost-lock-free malloc implementation.
+
+This is intended as a safe way to allocate memory from a signal handler,
+or to allocate memory in the context of a library that does not know what
+thread library it will be used with.  In either case locking is impossible.
+
+Note that the operations are only guaranteed to be 1-lock-free, i.e. a
+single blocked thread will not prevent progress, but multiple blocked
+threads may.  To safely use these operations in a signal handler,
+the handler should be non-reentrant, i.e. it should not be interruptable
+by another handler using these operations.  Furthermore use outside
+of signal handlers in a multithreaded application should be protected
+by a lock, so that at most one invocation may be interrupted by a signal.
+The header will define the macro "AO_MALLOC_IS_LOCK_FREE" on platforms
+on which malloc is completely lock-free, and hence these restrictions
+do not apply.
+
+In the presence of threads, but absence of contention, the time performance
+of this package should be as good, or slightly better than, most system
+malloc implementations.  Its space performance
+is theoretically optimal (to within a constant factor), but probably
+quite poor in practice.  In particular, no attempt is made to
+coalesce free small memory blocks.  Something like Doug Lea's malloc is
+likely to use significantly less memory for complex applications.
+
+Performance on platforms without an efficient compare-and-swap implementation
+will be poor.
+
+This package was not designed for processor-scalability in the face of
+high allocation rates.  If all threads happen to allocate different-sized
+objects, you might get lucky.  Otherwise expect contention and false-sharing
+problems.  If this is an issue, something like Maged Michael's algorithm
+(PLDI 2004) would be technically a far better choice.  If you are concerned
+only with scalability, and not signal-safety, you might also consider
+using Hoard instead.  We have seen a factor of 3 to 4 slowdown from the
+standard glibc malloc implementation with contention, even when the
+performance without contention was faster.  (To make the implementation
+more scalable, one would need to replicate at least the free list headers,
+so that concurrent access is possible without cache conflicts.)
+
+Unfortunately there is no portable async-signal-safe way to obtain large
+chunks of memory from the OS.  Based on reading of the source code,
+mmap-based allocation appears safe under Linux, and probably BSD variants.
+It is probably unsafe for operating systems built on Mach, such as
+Apple's Darwin.  Without use of mmap, the allocator is
+limited to a fixed size, statically preallocated heap (2MB by default),
+and will fail to allocate objects above a certain size (just under 64K
+by default).  Use of mmap to circumvent these limitations requires an
+explicit call.
+
+The entire interface to the AO_malloc package currently consists of:
+
+#include <atomic_ops_malloc.h> /* includes atomic_ops.h */
+
+void *AO_malloc(size_t sz);
+void AO_free(void *p);
+void AO_malloc_enable_mmap(void);

+Note that the AO_stack implementation is licensed under the GPL,
+unlike the lower level routines.
+
+The header file atomic_ops_stack.h defines a linked stack abstraction.
+Stacks may be accessed by multiple concurrent threads.  The implementation
+is 1-lock-free, i.e. it will continue to make progress if at most one
+thread becomes inactive while operating on the data structure.
+
+(The implementation can be built to be N-lock-free for any given N.  But that
+seems to rarely be useful, especially since larger N involve some slowdown.)
+
+This makes it safe to access these data structures from non-reentrant
+signal handlers, provided at most one non-signal-handler thread is
+accessing the data structure at once.  This latter condition can be
+ensured by acquiring an ordinary lock around the non-handler accesses
+to the data structure.
+
+For details see:
+
+Hans-J. Boehm, "An Almost Non-Blocking Stack", PODC 2004,
+http://portal.acm.org/citation.cfm?doid=1011767.1011774, or
+http://www.hpl.hp.com/techreports/2004/HPL-2004-105.html
+(This is not exactly the implementation described there, since the
+interface was cleaned up in the interim.  But it should perform
+very similarly.)
+
+We use a fully lock-free implementation when the underlying hardware
+makes that less expensive, i.e. when we have a double-wide compare-and-swap
+operation available.  (The fully lock-free implementation uses an AO_t-
+sized version count, and assumes it does not wrap during the time any
+given operation is active.  This seems reasonably safe on 32-bit hardware,
+and very safe on 64-bit hardware.) If a fully lock-free implementation
+is used, the macro AO_STACK_IS_LOCK_FREE will be defined.
+
+The implementation is interesting only because it allows reuse of
+existing nodes.  This is necessary, for example, to implement a memory
+allocator.
+
+Since we want to leave the precise stack node type up to the client,
+we insist only that each stack node contains a link field of type AO_t.
+When a new node is pushed on the stack, the push operation expects to be
+passed the pointer to this link field, which will then be overwritten by
+this link field.  Similarly, the pop operation returns a pointer to the
+link field of the object that previously was on the top of the stack.
+
+The cleanest way to use these routines is probably to define the stack node
+type with an initial AO_t link field, so that the conversion between the
+link-field pointer and the stack element pointer is just a compile-time
+cast.  But other possibilities exist.  (This would be cleaner in C++ with
+templates.)
+
+A stack is represented by an AO_stack_t structure.  (This is normally
+2 or 3 times the size of a pointer.)  It may be statically initialized
+by setting it to AO_STACK_INITIALIZER, or dynamically initialized to
+an empty stack with AO_stack_init.  There are only three operations for
+accessing stacks:
+
+void AO_stack_init(AO_stack_t *list);
+void AO_stack_push_release(AO_stack_t *list, AO_t *new_element);
+AO_t * AO_stack_pop_acquire(volatile AO_stack_t *list);
+
+We require that the objects pushed as list elements remain addressable
+as long as any push or pop operation are in progress.  (It is OK for an object
+to be "pop"ped off a stack and "deallocated" with a concurrent "pop" on
+the same stack still in progress, but only if "deallocation" leaves the
+object addressable.  The second "pop" may still read the object, but
+the value it reads will not matter.)
+
+We require that the headers (AO_stack objects) remain allocated and
+valid as long as any operations on them are still in-flight.
+
+We also provide macros AO_REAL_HEAD_PTR that converts an AO_stack_t
+to a pointer to the link field in the next element, and AO_REAL_NEXT_PTR
+that converts a link field to a real, dereferencable, pointer to the link field
+in the next element.  This is intended only for debugging, or to traverse
+the list after modification has ceased.  There is otherwise no guarantee that
+walking a stack using this macro will produce any kind of consistent
+picture of the data structure.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us

+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always

+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything

+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until

+ * Routines for accessing dirty bits on virtual pages.
+ * There are six ways to maintain this information:
+ * DEFAULT_VDB: A simple dummy implementation that treats every page
+ *              as possibly dirty.  This makes incremental collection
+ *              useless, but the implementation is still correct.
+ * MANUAL_VDB:  Stacks and static data are always considered dirty.
+ *              Heap pages are considered dirty if GC_dirty(p) has been
+ *              called on some pointer p pointing to somewhere inside
+ *              an object on that page.  A GC_dirty() call on a large
+ *              object directly dirties only a single page, but for
+ *              MANUAL_VDB we are careful to treat an object with a dirty
+ *              page as completely dirty.
+ *              In order to avoid races, an object must be marked dirty
+ *              after it is written, and a reference to the object
+ *              must be kept on a stack or in a register in the interim.
+ *              With threads enabled, an object directly reachable from the
+ *              stack at the time of a collection is treated as dirty.
+ *              In single-threaded mode, it suffices to ensure that no
+ *              collection can take place between the pointer assignment
+ *              and the GC_dirty() call.
+ * PCR_VDB:     Use PPCRs virtual dirty bit facility.
+ * PROC_VDB:    Use the /proc facility for reading dirty bits.  Only
+ *              works under some SVR4 variants.  Even then, it may be
+ *              too slow to be entirely satisfactory.  Requires reading
+ *              dirty bits for entire address space.  Implementations tend
+ *              to assume that the client is a (slow) debugger.
+ * MPROTECT_VDB:Protect pages and then catch the faults to keep track of
+ *              dirtied pages.  The implementation (and implementability)
+ *              is highly system dependent.  This usually fails when system
+ *              calls write to a protected page.  We prevent the read system
+ *              call from doing so.  It is the clients responsibility to
+ *              make sure that other system calls are similarly protected
+ *              or write only to the stack.
+ * GWW_VDB:     Use the Win32 GetWriteWatch functions, if available, to
+ *              read dirty bits.  In case it is not available (because we
+ *              are running on Windows 95, Windows 2000 or earlier),
+ *              MPROTECT_VDB may be defined as a fallback strategy.

+ * Some simple primitives for allocation with explicit type information.
+ * Simple objects are allocated such that they contain a GC_descr at the
+ * end (in the last allocated word).  This descriptor may be a procedure
+ * which then examines an extended descriptor passed as its environment.
+ *
+ * Arrays are treated as simple objects if they have sufficiently simple
+ * structure.  Otherwise they are allocated from an array kind that supplies
+ * a special mark procedure.  These arrays contain a pointer to a
+ * complex_descriptor as their last word.
+ * This is done because the environment field is too small, and the collector
+ * must trace the complex_descriptor.
+ *
+ * Note that descriptors inside objects may appear cleared, if we encounter a
+ * false reference to an object on a free list.  In the GC_descr case, this
+ * is OK, since a 0 descriptor corresponds to examining no fields.
