+2008-07-25 Hans Boehm <Hans.Boehm@hp.com> (Really mostly Ivan Maidanski)
+ Ivan's description of the patch follows. Note that a few pieces like
+ the GC_malloc(0) patch, were not applied since an alternate had been
+ previously applied. A few differed stylistically from the rest of
+ the code (mostly casts to void * instead of target type),
+ or were classified as too minor to bother. Note that
+ all of Ivan's static declarations which did not correct outright
+ naming bugs (as a few did), where replaced by STATIC, which is
+ ignored by default.
+
+ - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
+ GC_malloc(0));
+ - addition of missing getter/setter functions for public variables
+ (may be useful if compiled as Win32 DLL);
+ - addition of missing GC_API for some exported functions;
+ - addition of missing "static" declarator for internal functions
+ and variables (where possible);
+ - replacement of all remaining K&R-style definitions with ANSI
+ C ones (__STDC__ macro is not used anymore);
+ - addition of some Win32 macro definitions (that may be missing in
+ the standard headers supplied with a compiler) for GWW_VDB mode;
+ - elimination of most compiler warnings (except for
+ "uninitialized data" warning);
+ - several typos correction;
+ - missing parenthesis addition in macros in some header files of
+ "libatomic_ops" module.
+
+ My highlights based on reading the patch:
+
+ * allchblk.c: Remove GC_freehblk_ptr decl.
+ Make free_list_index_of() static.
+ * include/gc.h: Use __int64 on win64, define GC_oom_func,
+ GC_finalizer_notifier_proc, GC_finalizer_notifier_proc,
+ add getter and setters: GC_get_gc_no, GC_get_parallel,
+ GC_set_oom_fn, GC_set_finalize_on_demand,
+ GC_set_java_finalization, GC_set_dont_expand,
+ GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect,
+ GC_set_finalizer_notifier. Always define GC_win32_free_heap.
+ gc_config_macros.h: Define _REENTRANT after processing
+ GC_THREADS.
+ * include/gc_cpp.h: Improve GC_PLACEMENT_DELETE test,
+ handling of operator new[] for old Windows compilers.
+ * include/gc_inline.h (GC_MALLOC_FAST_GRANS): Add parentheses
+ around arguments.
+ * dbg_mlc.c, malloc.c, misc.c: Add many GC_API specs.
+ * mark.c (GC_mark_and_push_stack): Fix source argument for
+ blacklist printing.
+ * misc.c: Fix log file naming based on environment variable
+ for Windows. Make GC_set_warn_proc and GC_set_free_space_divisor
+ just return current value with 0 argument. Add DONT_USER_USER32_DLL.
+ Add various getters and setters as in gc.h.
+ * os_dep.c: Remove no longer used GC_disable/enable_signals
+ implementations. (GC_get_stack_base): Add pthread_attr_destroy
+ call. No longer set GC_old_bus_handler in DARWIN workaround.
+ * pthread_support.c: GC_register_my_thread must also
+ call GC_init_thread_local.
+

+ * Makefile.direct, mach_dep.c: Add support for NO_GETCONTEXT.

+
+ * include/private/gcconfig.h: Update MIPS/LINUX config.
+ * doc/gcdescr.html: Fix typo.
+ * mach_dep.c (GC_with_callee_saves_pushed): Don't rely on getcontext
