libjava: 2004-08-13 Bryce McKinlay <mckinlay@redhat.com> * configure.in (GCINCS): Don't use "boehm-cflags". Instead, -I boehm-gc's include dirs. * configure: Rebuilt. * include/boehm-gc.h: Include gc_config.h. boehm-gc: 2004-08-13 Bryce McKinlay <mckinlay@redhat.com> * configure.ac (gc_cflags): Add -Iinclude. (AC_CONFIG_HEADERS): New. Configure gc_config.h header. Don't write DEFS to boehm-cflags file. * configure: Rebuilt. * gcj_mlc.c: Check #ifdef GC_GCJ_SUPPORT after including headers. * specific.c: Check #ifdef GC_LINUX_THREADS after including headers. * include/gc_config_macros.h: Remove backward-compatibility redefinitions of GC_ names. * include/gc.h: Include <gc_config.h>. 2004-08-13 Bryce McKinlay <mckinlay@redhat.com> Import Boehm GC version 6.3.

/*
|
|
* Interface for thread local allocation. Memory obtained
|
|
* this way can be used by all threads, as though it were obtained
|
|
* from an allocator like GC_malloc. The difference is that GC_local_malloc
|
|
* counts the number of allocations of a given size from the current thread,
|
|
* and uses GC_malloc_many to perform the allocations once a threashold
|
|
* is exceeded. Thus far less synchronization may be needed.
|
|
* Allocation of known large objects should not use this interface.
|
|
* This interface is designed primarily for fast allocation of small
|
|
* objects on multiprocessors, e.g. for a JVM running on an MP server.
|
|
*
|
|
* If this file is included with GC_GCJ_SUPPORT defined, GCJ-style
|
|
* bitmap allocation primitives will also be included.
|
|
*
|
|
* If this file is included with GC_REDIRECT_TO_LOCAL defined, then
|
|
* GC_MALLOC, GC_MALLOC_ATOMIC, and possibly GC_GCJ_MALLOC will
|
|
* be redefined to use the thread local allocatoor.
|
|
*
|
|
* The interface is available only if the collector is built with
|
|
* -DTHREAD_LOCAL_ALLOC, which is currently supported only on Linux.
|
|
*
|
|
* The debugging allocators use standard, not thread-local allocation.
|
|
*
|
|
* These routines normally require an explicit call to GC_init(), though
|
|
* that may be done from a constructor function.
