* Code refactoring of Emscripten platform support (single-threaded)Ivan Maidanski2014-07-131-4/+4
| | | | | | | | | | | | | | | | | | * alloc.c (min_bytes_allocd): Test STACK_NOT_SCANNED macro instead of __EMSCRIPTEN__ (stack size to scan is zero if STACK_NOT_SCANNED). * include/private/gcconfig.h (ALIGNMENT): Remove duplicate definition for _EMSCRIPTEN__. * include/private/gcconfig.h (STACK_NOT_SCANNED): New macro defined for __EMSCRIPTEN__ target (in addition to OS_TYPE, CPP_WORDSZ, ALIGNMENT, DATASTART, DATAEND). * mach_dep.c (GC_push_regs): Test STACK_NOT_SCANNED macro instead of __EMSCRIPTEN__ (push nothing if STACK_NOT_SCANNED). * mark_rts.c (GC_push_roots): Test STACK_NOT_SCANNED macro instead of __EMSCRIPTEN__ (do not call GC_push_regs_and_stack if STACK_NOT_SCANNED); mark cold_gc_frame argument as potentially unused. * misc.c (GC_clear_stack): Test STACK_NOT_SCANNED macro instead of __EMSCRIPTEN__ (do not clear stack if STACK_NOT_SCANNED). * misc.c (GC_clear_stack): Reformat code.

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

| | | | | | | | | | | | | | | | * allchblk.c (GC_enough_large_bytes_left): No longer take parameters; return free list index bound. (GC_merge_unmapped): Don't access nexthdr until after null test. (Fixes bug in 1/29/08 check-in.) (GC_allochblk): Calculate when splitting is allowable only once here, not when considering each block. (GC_allchblk_nth): Accept new may_split parameter. Avoid some redundant tests for exact size matches. * alloc.c (GC_should_collect): Cache min_bytes_allocd. (GC_maybe_gc): Make locking assertion testable. * mark_rts.c: Fix indentation. * pthread_stop_world.c: Replace old GC_err_printf1 reference. * tests/test.c: Remove (void) casts. Optionally print some timing information.
