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
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.

-# -DDONT_ADD_BYTE_AT_END disables the padding.
-# -DNO_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.
-# -DGC_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.
-# -DREDIRECT_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 strdup 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.
-# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
-# The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
-# together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
-# generate leak reports with call stacks for both malloc and realloc.
-# This also requires the following:
-# -DREDIRECT_FREE=X causes free to be redirected to X. The
-# canonical use is -DREDIRECT_FREE=GC_debug_free.
-# -DIGNORE_FREE turns calls to free into a noop. Only useful with
-# -DREDIRECT_MALLOC.
-# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
-# Reduces code size slightly at the expense of debuggability.
-# -DJAVA_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 postpass, 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.
-# -DFINALIZE_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.
-# -DATOMIC_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.
-# -DMARK_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.
-# -DMARK_BIT_PER_OBJ requests that a mark bit be allocated for each
-# object instead of allocation granule. The opposiet of
-# MARK_BIT_PER_GRANULE.
-# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
-# sets the heap block size. 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.
-# -DUSE_MMAP use MMAP instead of sbrk to get new memory.
-# Works for Solaris and Irix.
-# -DUSE_MUNMAP causes memory to be returned to the OS under the right
-# circumstances. This currently disables VM-based incremental collection.
-# This is currently experimental, and works only under some Unix,
-# Linux and Windows versions.
-# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
-# GC_scratch_alloc() to get stack memory.
-# -DPRINT_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 identifiy regions of
-# memory that are likely to contribute misidentified pointers.
-# -DKEEP_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.
-# -DGC_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
-# -DDBG_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 -DSHORT_DBG_HDRS possible.
-# Assumes that all client allocation is done through debugging
-# allocators.
-# -DSHORT_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 be useful for debugging of client code. Slows down the
-# collector somewhat, but not drastically.
-# -DSAVE_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.
-# -DSAVE_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.
-# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
-# altered stubborn objects, at substantial performance cost.
-# Use only for debugging of the incremental collector.
-# -DGC_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.
-# -DUSE_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.
-# -DUSE_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.
-# -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
-# prefetch instructions. No effect except on PowerPC OS X platforms.
-# Performance impact untested.
-# -DGC_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.
-# -DGC_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.
-# -DTHREAD_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. Currently supported only on platforms
-# such as Linux that use pthread_support.c. Recommended for multiprocessors.
-# Requires explicit GC_INIT() call.
-# -DUSE_COMPILER_TLS causes thread local allocation to use 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.)
-# -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended
-# for multiprocessors. Currently requires Linux on X86 or IA64, though
-# support for other Posix platforms should be fairly easy to add,
-# if the thread implementation is otherwise supported.
-# -DNO_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?
-# -DUSE_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.
-# -DMAKE_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.
-# -DSTUBBORN_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.
-# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
-# from a multithreaded parent. Currently only supported by pthread_support.c.
-# (Similar code should work on Solaris or Irix, but it hasn't been tried.)
-# -DTEST_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 malloced memory is
-# somehow getting traced by the collector. This has no impact on the
-# generated library; it only affects the test.
-# -DNO_INCREMENTAL cases 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.)
-# -DPOINTER_MASK=0x... causes candidate pointers to be ANDed 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.
-# -DPOINTER_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.
-# -DENABLE_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.
-# -DDARWIN_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 onthe stack. This is recommended only as a fallback
-# for applications that don't support proper stack unwinding.

# Setjmp_test may yield overly optimistic results when compiled
# without optimization.
-# These define arguments influence the collector configuration:
-# -DFIND_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.
-#
-# 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.
-# -DGC_THREADS should set the appropriate one of the below macros,
-# except -DGC_WIN32_PTHREADS, which must be set explicitly.
-# -DGC_SOLARIS_THREADS enables support for Solaris pthreads.
-# Must also define -D_REENTRANT.
-# -DGC_IRIX_THREADS enables support for Irix pthreads. See README.irix.
-# -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
-# Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
-# -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads
-# or NPTL threads. See README.linux. -D_REENTRANT may also be required.
-# -DGC_OSF1_THREADS enables support for Tru64 pthreads.
-# -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.
-# Appeared to run into some underlying thread problems.
-# -DGC_DARWIN_THREADS enables support for Mac OS X pthreads.
-# -DGC_AIX_THREADS enables support for IBM AIX threads.
-# -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
-# See README.DGUX386. (Probably has not been tested recently.)
-# -DGC_WIN32_THREADS enables support for win32 threads. That makes sense
-# for this Makefile only under Cygwin.
-# -DGC_WIN32_PTHREADS enables support for Ming32 pthreads. This cannot be
-# enabled automatically by GC_THREADS, which would assume Win32 native
-# threads.
-# -DPTW32_STATIC_LIB causes the static version of the Mingw pthreads library
-# to be used. Requires -DGC_WIN32_PTHREADS.
-#
-# -DALL_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.
-# -DSMALL_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.
-# -DLARGE_CONFIG tunes the collector for unusually large heaps.
-# Necessary for heaps larger than about 500 MB on most machines.
-# Recommended for heaps larger than about 64 MB.
-# -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or
-# GC_all_interior_pointers = 1. Normally -DALL_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.)
-# -DDONT_ADD_BYTE_AT_END disables the padding.
-# -DNO_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.
-# -DGC_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.
-# -DREDIRECT_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 strdup 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.
-# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
-# The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
-# together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
-# generate leak reports with call stacks for both malloc and realloc.
-# This also requires the following:
-# -DREDIRECT_FREE=X causes free to be redirected to X. The
-# canonical use is -DREDIRECT_FREE=GC_debug_free.
-# -DIGNORE_FREE turns calls to free into a noop. Only useful with
-# -DREDIRECT_MALLOC.
-# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
-# Reduces code size slightly at the expense of debuggability.
-# -DJAVA_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 postpass, 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.
-# -DFINALIZE_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.
-# -DATOMIC_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.
-# -DMARK_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.
-# -DMARK_BIT_PER_OBJ requests that a mark bit be allocated for each
-# object instead of allocation granule. The opposite of
-# MARK_BIT_PER_GRANULE.
-# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
-# sets the heap block size. 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.
-# -DUSE_MMAP use MMAP instead of sbrk to get new memory.
-# Works for Linux, FreeBSD, Cygwin, Solaris and Irix.
-# -DUSE_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 -DUSE_MMAP except for Windows.
-# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
-# GC_scratch_alloc() to get stack memory.
-# -DPRINT_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.
-# -DKEEP_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.
-# -DGC_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
-# -DDBG_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 -DSHORT_DBG_HDRS possible.
-# Assumes that all client allocation is done through debugging
-# allocators.
-# -DSHORT_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.)
-# -DSAVE_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.
-# -DSAVE_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.
-# -DCHECKSUMS 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.
-# -DGC_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.
-# -DUSE_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.
-# -DUSE_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.
-# -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
-# prefetch instructions. No effect except on PowerPC OS X platforms.
-# Performance impact untested.
-# -DGC_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.
-# -DGC_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.
-# -DTHREAD_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.
-# -DUSE_COMPILER_TLS causes thread local allocation to use 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.)
-# -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended
-# for multiprocessors.
-# -DNO_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?
-# -DUSE_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.
-# -DMAKE_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.
-# -DSTUBBORN_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.
-# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
-# from a multithreaded parent. Currently only supported by pthread_support.c.
-# (Similar code should work on Solaris or Irix, but it hasn't been tried.)
-# -DTEST_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 malloced memory is
-# somehow getting traced by the collector. This has no impact on the
-# generated library; it only affects the test.
-# -DNO_INCREMENTAL cases 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.)
-# -DPOINTER_MASK=0x... causes candidate pointers to be ANDed 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.
-# -DPOINTER_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.
-# -DENABLE_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.
-# -DDARWIN_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 onthe stack. This is recommended only as a fallback
-# for applications that don't support proper stack unwinding.
-# -DUSE_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
-# informaing the collector. But it typically performs poorly, especially
-# since it will scan inactive but cached NPTL thread stacks completely.
-# -DNO_PROC_STAT Causes the collector to avoid relying on Linux'
-# /proc/self/stat.
-# -DNO_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.
-# -DSTATIC=static Causes various GC_ symbols that could logically be
-# declared static to be declared (this is the default if -DNO_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.
-# -DDONT_USE_USER32_DLL (Win32 only) Don't use "user32" DLL import library
-# (containing MessageBox() entry); useful for a static GC library.
-# -DGC_PREFER_MPROTECT_VDB Choose MPROTECT_VDB manually in case of multiple
-# virtual dirty bit strategies are implemented (at present useful on Win32
-# to force MPROTECT_VDB strategy instead of the default GWW_VDB one).
-#
+# Look into doc/README.macros for the description of the "define arguments"

-# Setjmp_test may yield overly optimistic results when compiled
-# without optimization.
-# -DFIND_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.
-# -DALL_INTERIOR_POINTERS allows all pointers to the interior
-# of objects to be recognized. (See gc_priv.h for consequences.)
-# -DSMALL_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.
-# -DLARGE_CONFIG tunes the collector for unusually large heaps.
-# Necessary for heaps larger than about 500 MB on most machines.
-# Recommended for heaps larger than about 64 MB.
-# -DDONT_ADD_BYTE_AT_END is meaningful only with
-# -DALL_INTERIOR_POINTERS. Normally -DALL_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.)
-# -DDONT_ADD_BYTE_AT_END disables the padding.
-# -DNO_SIGNALS does not disable signals during critical parts of
-# the GC process. This is no less correct than many malloc
-# implementations, and it sometimes has a significant performance
-# impact. However, it is dangerous for many not-quite-ANSI C
-# programs that call things like printf in asynchronous signal handlers.
-# This is on by default. Turning it off has not been extensively tested with
-# compilers that reorder stores. It should have been.
-# -DNO_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.
-# -DGC_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.
-# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
-# as aliases for X, GC_realloc, and GC_free, respectively.
-# Calloc is redefined in terms of the new malloc. X should
-# be either GC_malloc or GC_malloc_uncollectable.
-# 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.)
-# -DIGNORE_FREE turns calls to free into a noop. Only useful with
-# -DREDIRECT_MALLOC.
-# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
-# Reduces code size slightly at the expense of debuggability.
-# -DJAVA_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 postpass, 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.
-# -DFINALIZE_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.
-# -DATOMIC_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.
-# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
-# sets the heap block size. 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.
-# -DPRINT_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 identifiy regions of
-# memory that are likely to contribute misidentified pointers.
-# -DKEEP_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.
-# -DGC_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
-# -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases
-# the reliability (from 99.9999% to 100%) of some of the debugging
-# code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible.
-# Assumes that all client allocation is done through debugging
-# allocators.
-# -DSHORT_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.
-# (Also eliminates the field for the requested object size.)
-# occasionally be useful for debugging of client code. Slows down the
-# collector somewhat, but not drastically.
-# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
-# altered stubborn objects, at substantial performance cost.
-# Use only for debugging of the incremental collector.
-# -DGC_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.
-# -DUSE_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.
-# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
-# prefetch instructions. Same restrictions as USE_I686_PREFETCH.
-# UNTESTED!!
-# -DGC_USE_LD_WRAP in combination with the gld 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.

-# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
-# created by `make install' are always world readable, even if the
-# installer happens to have an overly restrictive umask (e.g. 077).
-# This was a mistake. There are at least two reasons why we must not
-# use `-m 0755':
-# - it causes special bits like SGID to be ignored,
-# - it may be too restrictive (some setups expect 775 directories).
-#
-# Do not use -m 0755 and let people choose whatever they expect by
-# setting umask.
-#
-# We cannot accept any implementation of `mkdir' that recognizes `-p'.
-# Some implementations (such as Solaris 8's) are not thread-safe: if a
-# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
-# concurrently, both version can detect that a/ is missing, but only
-# one can create it and the other will error out. Consequently we
-# restrict ourselves to GNU make (using the --version option ensures
-# this.)

8) GC_enable_incremental()

unreachable. To call (*f)(obj, x) when obj becomes inaccessible, use

For more sophisticated uses, and for finalization ordering issues,
see gc.h.
Some additional tuning is possible through the parameters defined

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 pointerfree
- objects or not. Although this is intended to be
- transparent, it may cause unintended system call failures.

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

- 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_FORCE_UNMAP_ON_GCOLLECT - Turn "unmap as much as possible on explicit GC"

-__DMC__ Always #define'd by the Digital Mars compiler. Expands
- to the compiler version number in hex, i.e. 0x810 is
- version 8.1b0
+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.
-
-_MSC_VER Expands to the Visual C++ compiler version. Assumed to
- not be defined for other compilers (at least if they behave
- appreciably differently).
-
-_DLL Defined by Visual C++ if dynamic libraries are being built
- or used. Used to test whether __declspec(dllimport) or
- __declspec(dllexport) needs to be added to declarations
- to support the case in which the collector is in a dll.
-
-GC_DLL User-settable macro that forces the effect of _DLL. Set
- by gc.h if _DLL is defined and GC_NOT_DLL is 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 only for MS Windows.
-
-GC_NOT_DLL User-settable macro that overrides _DLL, e.g. if dynamic
- libraries are used, but the collector is in a static library.
-
-__STDC__ Assumed to be defined only by compilers that understand

+
+_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

+ This is the macro that is tested internally to determine

+ 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.
+
+
+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.

+
+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.
+
+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.
+
+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.
+
+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 strdup 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).
+
+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.
+
+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 Attempts to make GC_malloc() work in a child process fork()'ed
+ from a multithreaded parent. Currently only supported by pthread_support.c.
+ (Similar code should work on Solaris or Irix, but it hasn't been tried.)
+
+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 onthe stack. This is recommended only as a fallback for
+ applications that don't support proper stack unwinding.
+
+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.
+
+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
+ to force MPROTECT_VDB strategy instead of the default GWW_VDB one).
+
+GC_NO_DLLMAIN (Win32+DLL only) Exclude DllMain-based thread registration
+ support.
+
+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_DONT_EXPAND Don't expand the heap unless explicitly requested or forced to.
+
+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.)
SOLARIS THREADS:
-The collector must be compiled with -DGC_SOLARIS_THREADS (thr_ functions)
-or -DGC_THREADS to be thread safe. This assumes use of the pthread_
-interface. Old style Solaris threads are no longer supported.

the collector test program "gctest" is linked as a GUI application,
but does not open any windows. Its output normally appears in the file
-"gctest.exe.log". It may be started from the file manager. The hour glass
+"gctest.gc.log". It may be started from the file manager. The hour glass
cursor may appear as long as it's running. If it is started from the
command line, it will usually run in the background. Wait a few
minutes (a few seconds on a modern machine) before you check the output.
We generally recommend avoiding this if possible, since it seems to
be less than 100% reliable.
-Use NT_THREADS_MAKEFILE (a.k.a gc.mak) instead of NT_MAKEFILE

For the normal, non-dll-based thread tracking to work properly,
threads should be created with GC_CreateThread or GC_beginthreadex,

win32_threads.c is currently broken and looking for someone to debug it.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- 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

- 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.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-
-Started sometime after version 0.4 release. Currently the format is
-informal. Eventually should become more GNU-like.
+++ /dev/null
-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.
-
-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.

-This package provides semi-portable access to hardware provided

-
-- 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
- ia also not always faster than lock-based code. But it may occasionally
- be a large performance win.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$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.

-# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:

-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]

- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']

- 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) */

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- 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:
-
- 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.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.
+++ /dev/null
-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
-license:
-
-----------------------------------------
-
-Copyright (c) ...
-
-Permission is hereby granted, free of charge, to any person obtaining a copy
-of this software and associated documentation files (the "Software"), to deal
-in the Software without restriction, including without limitation the rights
-to use, copy, modify, merge, publish, distribute, sublicense, and/or sell
-copies of the Software, and to permit persons to whom the Software is
-furnished to do so, subject to the following conditions:
-
-The above copyright notice and this permission notice shall be included in all
-copies or substantial portions of the Software.
-
-THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR

-OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
-SOFTWARE.
-
---------------------------------
-
-A few files in the sysdeps directory were inherited in part from the
-Boehm-Demers-Weiser conservative garbage collector, and are covered by
-its license, which is similar in spirit:
-
---------------------------------
-
-Copyright (c) ...
-
-THIS MATERIAL IS PROVIDED AS IS, WITH ABSOLUTELY NO WARRANTY EXPRESSED
-OR IMPLIED. ANY USE IS AT YOUR OWN RISK.
-
-Permission is hereby granted to use or copy this program
-for any purpose, provided the above notices are retained on all copies.
-Permission to modify the code and to distribute modified code is granted,
-provided the above notices are retained, and a notice that the code was
-modified is included with the above copyright notice.
-
-----------------------------------
-
-A few files are covered by the GNU General Public License. (See file
-"COPYING".) This applies only to test code, sample applications,
-and the libatomic_ops_gpl portion of the library.
-Thus libatomic_ops_gpl should generally not be linked into proprietary code.
-(This distinction was motivated by patent considerations.)
-
-It is possible that the license of the GPL pieces may be changed for
-future versions to make them more consistent with the rest of the package.
-If you submit patches, and have strong preferences about licensing, please
-express them.

-.NOEXPORT:
+++ /dev/null
-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 the two values AO_TS_SET and
- 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 repsect 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 memops.
- 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.
+++ /dev/null
-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.
-
-Perfomance 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 scalablity, 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);
+++ /dev/null
-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-hndler 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.
+++ /dev/null
-Most of the atomic_ops functionality is available under Win32 with
-the Microsoft tools, but the build process currently is considerably more
-primitive than on Linux/Unix platforms.
-
-To build:
-
-1) Go to the src directory in the distribution.
-2) Make sure the Microsoft command-line tools (e.g. nmake) are available.
-3) Run "nmake -f Makefile.msft". This should run some tests, which
-may print warnings about the types of the "Interlocked" functions.
-I haven't been able to make all versions of VC++ happy. If you know
-how to, please send a patch.
-4) To compile applications, you will need to retain or copy the following
-pieces from the resulting src directory contents:
- "atomic_ops.h" - Header file defining low-level primitives. This
- includes files from:
- "atomic_ops"- Subdirectory containing implementation header files.
- "atomic_ops_stack.h" - Header file describing almost lock-free stack.
- "atomic_ops_malloc.h" - Header file describing almost lock-free malloc.
- "libatomic_ops_gpl.lib" - Library containing implementation of the
- above two. The atomic_ops.h implementation
- is entirely in the header files in Win32.
-
-Most clients of atomic_ops.h will need to define AO_ASSUME_WINDOWS98 before
-including it. Compare_and_swap is otherwise not available.
-
-Note that the library is covered by the GNU General Public License, while
-the top 2 of these pieces allow use in proprietary code.

-/* We define various atomic operations on memory in a */

-/* by the fact that these may or may not be combined with */
-/* various memory barriers. Thus the actual operations we */
-/* define have the form AO_<atomic-op>_<barrier>, for all */
-/* plausible combinations of <atomic-op> and <barrier>. */
-/* This of course results in a mild combinatorial explosion. */
-/* To deal with it, we try to generate derived */
-/* definitions for as many of the combinations as we can, as */
-/* automatically as possible. */
-/* */
-/* Our assumption throughout is that the programmer will */
-/* specify the least demanding operation and memory barrier */
-/* that will guarantee correctness for the implementation. */
-/* Our job is to find the least expensive way to implement it */
-/* on the applicable hardware. In many cases that will */
-/* involve, for example, a stronger memory barrier, or a */
-/* combination of hardware primitives. */
-/* */
-/* Conventions: */
-/* "plain" atomic operations are not guaranteed to include */
-/* a barrier. The suffix in the name specifies the barrier */
-/* type. Suffixes are: */
-/* _release: Earlier operations may not be delayed past it. */
-/* _acquire: Later operations may not move ahead of it. */
-/* _read: Subsequent reads must follow this operation and */
-/* preceding reads. */
-/* _write: Earlier writes precede both this operation and */
-/* later writes. */
-/* _full: Ordered with respect to both earlier and later memops.*/
-/* _release_write: Ordered with respect to earlier writes. */
-/* _acquire_read: Ordered with respect to later reads. */
-/* */
-/* Currently we try to define the following atomic memory */
-/* operations, in combination with the above barriers: */
-/* AO_nop */
-/* AO_load */
-/* AO_store */
-/* AO_test_and_set (binary) */
-/* AO_fetch_and_add */
-/* AO_fetch_and_add1 */
-/* AO_fetch_and_sub1 */
-/* AO_or */
-/* AO_compare_and_swap */
-/* */
-/* Note that atomicity guarantees are valid only if both */
-/* readers and writers use AO_ operations to access the */
-/* shared value, while ordering constraints are intended to */
-/* apply all memory operations. If a location can potentially */
-/* be accessed simultaneously from multiple threads, and one of */
-/* those accesses may be a write access, then all such */
-/* accesses to that location should be through AO_ primitives. */
-/* However if AO_ operations enforce sufficient ordering to */
-/* ensure that a location x cannot be accessed concurrently, */
-/* or can only be read concurrently, then x can be accessed */
-/* via ordinary references and assignments. */
-/* */
-/* Compare_and_exchange takes an address and an expected old */
-/* value and a new value, and returns an int. Nonzero */
-/* indicates that it succeeded. */
-/* Test_and_set takes an address, atomically replaces it by */
-/* AO_TS_SET, and returns the prior value. */
-/* An AO_TS_t location can be reset with the */
-/* AO_CLEAR macro, which normally uses AO_store_release. */
-/* AO_fetch_and_add takes an address and an AO_t increment */
-/* value. The AO_fetch_and_add1 and AO_fetch_and_sub1 variants */
-/* are provided, since they allow faster implementations on */
-/* some hardware. AO_or atomically ors an AO_t value into a */
-/* memory location, but does not provide access to the original.*/
-/* */
-/* We expect this list to grow slowly over time. */
-/* */
-/* Note that AO_nop_full is a full memory barrier. */
-/* */
-/* Note that if some data is initialized with */
-/* data.x = ...; data.y = ...; ... */
-/* AO_store_release_write(&data_is_initialized, 1) */
-/* then data is guaranteed to be initialized after the test */
-/* if (AO_load_release_read(&data_is_initialized)) ... */
-/* succeeds. Furthermore, this should generate near-optimal */
-/* code on all common platforms. */
-/* */
-/* All operations operate on unsigned AO_t, which */
-/* is the natural word size, and usually unsigned long. */
-/* It is possible to check whether a particular operation op */
-/* is available on a particular platform by checking whether */
-/* AO_HAVE_op is defined. We make heavy use of these macros */
-/* internally. */

-/* The rest of this file basically has three sections: */
-/* */
-/* Some utility and default definitions. */
-/* */
-/* The architecture dependent section: */
-/* This defines atomic operations that have direct hardware */
-/* support on a particular platform, mostly by including the */
-/* appropriate compiler- and hardware-dependent file. */
-/* */
-/* The synthesis section: */
-/* This tries to define other atomic operations in terms of */
-/* those that are explicitly available on the platform. */
-/* This section is hardware independent. */
-/* We make no attempt to synthesize operations in ways that */
-/* effectively introduce locks, except for the debugging/demo */
-/* pthread-based implementation at the beginning. A more */
-/* realistic implementation that falls back to locks could be */
-/* added as a higher layer. But that would sacrifice */

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ 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:
+
+ 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.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007, 2008 Free Software Foundation, Inc.
+
+ This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+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.
+
+ 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.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. 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.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+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 `..'.
+
+ 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'.
+
+ 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.
+
+ 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'.
+
+Optional Features
+=================
+
+ 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.
+
+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"
+
+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"
+
+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 1.3alpha1 of libatomic_ops.
+
+You might find a more recent version of this at
+
+http://www.hpl.hp.com/personal/Hans_Boehm/gc
+
+or
+
+http://www.hpl.hp.com/research/linux/atomic_ops/
+
+
+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.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$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.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ 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()

+ 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) */

+ 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:
+
+ 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
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.
--- /dev/null
+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
+license:
+
+----------------------------------------
+
+Copyright (c) ...
+
+Permission is hereby granted, free of charge, to any person obtaining a copy
+of this software and associated documentation files (the "Software"), to deal
+in the Software without restriction, including without limitation the rights
+to use, copy, modify, merge, publish, distribute, sublicense, and/or sell
+copies of the Software, and to permit persons to whom the Software is
+furnished to do so, subject to the following conditions:
+
+The above copyright notice and this permission notice shall be included in all
+copies or substantial portions of the Software.
+
+THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
+IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
+FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
+AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER
+LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
+OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
+SOFTWARE.
+
+--------------------------------
+
+A few files in the sysdeps directory were inherited in part from the
+Boehm-Demers-Weiser conservative garbage collector, and are covered by
+its license, which is similar in spirit:
+
+--------------------------------
+
+Copyright (c) ...
+
+THIS MATERIAL IS PROVIDED AS IS, WITH ABSOLUTELY NO WARRANTY EXPRESSED
+OR IMPLIED. ANY USE IS AT YOUR OWN RISK.
+
+Permission is hereby granted to use or copy this program
+for any purpose, provided the above notices are retained on all copies.
+Permission to modify the code and to distribute modified code is granted,
+provided the above notices are retained, and a notice that the code was
+modified is included with the above copyright notice.
+
+----------------------------------
+
+A few files are covered by the GNU General Public License. (See file
+"COPYING".) This applies only to test code, sample applications,
+and the libatomic_ops_gpl portion of the library.
+Thus libatomic_ops_gpl should generally not be linked into proprietary code.
+(This distinction was motivated by patent considerations.)
+
+It is possible that the license of the GPL pieces may be changed for
+future versions to make them more consistent with the rest of the package.
+If you submit patches, and have strong preferences about licensing, please
+express them.

+.NOEXPORT:
--- /dev/null
+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 the two values AO_TS_SET and
+ 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 repsect 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 memops.
+ 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.
--- /dev/null
+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.
+
+Perfomance 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 scalablity, 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);
--- /dev/null
+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-hndler 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.
--- /dev/null
+Most of the atomic_ops functionality is available under Win32 with
+the Microsoft tools, but the build process currently is considerably more
+primitive than on Linux/Unix platforms.
+
+To build:
+
+1) Go to the src directory in the distribution.
+2) Make sure the Microsoft command-line tools (e.g. nmake) are available.
+3) Run "nmake -f Makefile.msft". This should run some tests, which
+may print warnings about the types of the "Interlocked" functions.
+I haven't been able to make all versions of VC++ happy. If you know
+how to, please send a patch.
+4) To compile applications, you will need to retain or copy the following
+pieces from the resulting src directory contents:
+ "atomic_ops.h" - Header file defining low-level primitives. This
+ includes files from:
+ "atomic_ops"- Subdirectory containing implementation header files.
+ "atomic_ops_stack.h" - Header file describing almost lock-free stack.
+ "atomic_ops_malloc.h" - Header file describing almost lock-free malloc.
+ "libatomic_ops_gpl.lib" - Library containing implementation of the
+ above two. The atomic_ops.h implementation
+ is entirely in the header files in Win32.
+
+Most clients of atomic_ops.h will need to define AO_ASSUME_WINDOWS98 before
+including it. Compare_and_swap is otherwise not available.
+
+Note that the library is covered by the GNU General Public License, while
+the top 2 of these pieces allow use in proprietary code.

+/* _full: Ordered with respect to both earlier and later memops.*/
+/* _release_write: Ordered with respect to earlier writes. */
+/* _acquire_read: Ordered with respect to later reads. */

+/* via ordinary references and assignments. */
+/* */
+/* Compare_and_exchange takes an address and an expected old */
+/* value and a new value, and returns an int. Nonzero */
