2001-04-05finalize.c: - Accomodate finalization requests for static objects.Hans Boehm1-4/+21
2001-04-04 Hans Boehm <hans_boehm@hp.com> * 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. From-SVN: r41102
