+
+2012-08-09 Ivan Maidanski <ivmai@mail.ru>
+
+ * doc/README: Change version to 7.2d (rev. D).
+
+2012-08-05 Ivan Maidanski <ivmai@mail.ru>
+
+ * config.guess: Regenerate (by autoreconf -vif using autoconf-2.68,
+ automake-1.11.1 and libtool-2.4).
+ * config.sub: Likewise.
+ * m4/libtool.m4: Likewise.
+
+2012-08-02 Ivan Maidanski <ivmai@mail.ru>
+
+ * misc.c (GC_clear_stack_inner): Use GC_approx_sp() instead of
+ "dummy[0]" set to "&dummy" value (that worked as expected only for
+ STACK_GROWS_DOWN case).
+
+2012-08-02 Ivan Maidanski <ivmai@mail.ru>
+
+ * alloc.c (min_bytes_allocd, GC_stopped_mark): Use GC_approx_sp()

+ local variable.
+ * misc.c (GC_clear_stack_inner): Store address of volatile 'dummy'
+ local array (i.e. 'sp' value) to its first element (and use it in the
+ comparison of addresses) to prevent any harmful optimizations as C
+ officially disallows comparisons of pointers to different objects
+ (e.g., some Mac OS X clang releases might turn a conditional
+ expression that uses 'dummy' address into a constant); update comment.
+ * misc.c (GC_call_with_stack_base): Use "&base" instead of "&dummy"
+ (it is safe to use address of base here); remove dummy variable.
+
+2012-08-01 Ivan Maidanski <ivmai@mail.ru>
+
+ * misc.c (GC_call_with_stack_base): Call GC_noop1 after fn()

+
+2012-06-16 Ivan Maidanski <ivmai@mail.ru>
+
+ * tests/test_cpp.cc (main): Call GC_set_all_interior_pointers(1)
+ before GC_INIT to ensure that the collector considers pointers to
+ object interiors as valid ones (such a pointer could emerge as
+ a result of a type cast to subclass in case of multiple inheritance);

+ * include/private/gc_priv.h (GC_scratch_alloc): Improve comment.
+ * os_dep.c (GC_print_address_map): If GC_get_maps return null then

+
+ * include/private/gc_priv.h (GC_push_all, GC_push_other_roots):

+
+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_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.

+ just return current value with 0 argument. Add DONT_USE_USER32_DLL.

+ * 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.
