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.

implementations. (GC_get_stack_base): Add pthread_attr_destroy

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,

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
