<<<<<<< ChangeLog
2000-04-26 Jakub Jelinek <jakub@redhat.com>
* gcconfig.h (SPARC): Define ALIGNMENT to 8 for 64bit SPARC.
(SPARC/LINUX): Use GC_SysVGetDataStart instead of LINUX_DATA_START
- sparc glibc does not provide it.
(SAVE_CALL_CHAIN, ASM_CLEAR_CODE): Define on sparc*-linux*.
Make STACKBOTTOM depend on the wordsize.
* os_dep.c (GC_SysVGetDataStart): Compile in on sparc*-linux*.
(struct frame): Declare on sparc*-linux*.
(GC_save_callers): Bias the frame pointers if needed (sparc64).
* mach_dep.c (GC_save_regs_in_stack): Optimize on sparc32.
Implement on sparc64.
(GC_clear_stack_inner): Implement on sparc64.
* gc_priv.h (GC_test_and_set): Implement for sparc.
* linux_threads.c (GC_suspend_handler, GC_push_all_stacks): Use
