2001-04-26 Alexandre Oliva * configure.in: Obtain THREADS with `gcc -v'. * configure: Rebuilt. 2001-04-05 Hans Boehm * misc.c: Back out buggy changes to stack clearing code. Reduce CLEAR_SIZE to 1/4 of original value to reduce time spent clearing memory. 2001-04-04 Hans Boehm * finalize.c: - Accomodate finalization requests for static objects. (Will be required by hash synchronization. May be needed in some configurations now.) * gc_priv.h: - Define MIN_WORDS. All allocation requests are rounded up to at least this size. Removes a subtle assumption that Java objects have a 2 word header. * gcconfig.h: - Adjust Linux/IA64 configuration for non-ancient kernels. (Necessary fix for IA64.) * linux_threads.c: - Fix syntax error in currently unused code. Will be needed for Linux/PA-RISC. * malloc.c: - Handle MIN_WORDS. * misc.c: - Handle MIN_WORDS. - Change stack cleaning code to typically clear about one tenth the memory it used to in the threads configuration. Occasionally still clear more. (This is really a fix for a long-standing and fairly significant performance bug with threads.) * os_dep.c: - Fix the code for finding the beginning of the data segment under Linux. I believe this is necessary for some IA64 Linux distributions. It will also helo other platforms, though those may additionally require a gcconfig.h adjustment. (This basically works around the absence of a data_start or __data_start definition in glibc.) * test.c: - Handle rounding due to MIN_WORDS. 2001-03-22 Tom Tromey * Makefile.am (gctest_LDFLAGS): Use -shared-libgcc. 2001-03-19 Tom Tromey * Makefile.in: Rebuilt. * Makefile.am (gctest_LDFLAGS): new macro. 2001-03-16 Tom Tromey * Makefile.in: Rebuilt. * Makefile.am (TESTS_ENVIRONMENT): New macro. 2001-01-23 Rod Stewart * gcconfig.h: Check for `__arm__', not `arm'. 2000-12-30 Bryce McKinlay * configure.in: Rename THREADLIB to THREADLIBS. * Makefile.am (LINK): Add $(THREADLIBS) to libtool command line.
