| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | * dbg_mlc.c: Use random() on all glibc systems. * mach_dep.c (GC_with_callee_saves_pushed): Don't use getcontext() on HURD. Add comment. * pthread_stop_world.c (GC_suspend_handler, GC_stop_init): Accomodate systems without SA_SIGINFO.
* 2007-08-03 Hans Boehm <Hans.Boehm@hp.com>hboehm2011-07-26
| | | | | | | | | | | | | | | | | | | * alloc.c, backgraph.c, headers.c, include/private/gc_priv.h: Maintain GC_our_memory and GC_n_memory. * dbg_mlc.c (GC_print_smashed_obj): Improve message. (GC_print_all_smashed_proc): Pass client object address instead of base. * dyn_load.c (sort_heap_sects): New. (GC_register_map_entries): Register sections that are contiguous and merged with our heap. * malloc.c, os_dep.c (GC_text_mapping): Check for just base name of libraries. * malloc.c (calloc): Check for special callers even with USE_PROC_FOR_LIBRARIES. Move assertion. Add rudimentary malloc/free tracing. * misc.c: No longer call GC_init_lib_bounds explicitly. * thread_local_alloc.c (GC_malloc, GC_malloc_atomic): Always initialize on demand. * tests/test.c: Call GC_INIT only when required.

| | | | | | | | | | | | | | | | | | | * Makefile.am, Makefile.direct: Add NT_X64_STATIC_THREADS_MAKEFILE. * Makefile.in: Regenerate. * NT_X64_STATIC_THREADS_MAKEFILE: Fix warning flags. * allochblk.c, alloc.c, blacklst.c, dbg_malc.c, dyn_load.c, finalize.c, headers.c, mach_dep.c, malloc.c, mark.c, misc.c, obj_map.c, os_dep.c, ptr_chck.c, reclaim.c, typd_mlc.c, win32_threads.c, cord/de_win.c, include/gc_mark.h, include/private/gc_hdrs.h, include/private/gc_pmark.h, include/private/gc_priv.h, tests/test_cpp.cc: Replace old style function declarations. Clean up integral types. Remove register declarations. The change in malloc.c and the "int descr" declaration in mark.c are the most likely to have been real bugs outside of win64. * msvc_dbg.c: Disable on win64. * win32_threads.c: Add AMD64 support. * include/gc.h: no backtrace on AMD64 for now.
