define __ia64__.) don't check libunwind stuff. check __libc_ia64_register_backing_store_base. * defines.h: declare rb_ia64_bsp and rb_ia64_flushrs. (flush_register_windows): call rb_ia64_flushrs on IA64. * ia64.s: new file for IA64. it is separated from C program files because Intel C++ Compiler for IA64 doesn't support inline assembly. * common.mk (ia64.$(OBJEXT)): new target. * ruby.h (RUBY_INIT_STACK): defined. (ruby_init_stack): declared for RUBY_INIT_STACK. * main.c (main): precedes RUBY_INIT_STACK before ruby_init. * gc.c (rb_gc_register_stack_start): new global variable on IA64. (garbage_collect): simplify register stack marking code. don't use libunwind. (Init_stack): initialize rb_gc_register_stack_start. (ruby_init_stack): new function for RUBY_INIT_STACK. * eval.c (struct thread): add bstr_pos member for original position of register stack. (rb_thread_save_context): simplify register stack saving code. don't use libunwind. (rb_thread_restore_context_0): new function. moved from rb_thread_restore_context except the stack position checking code. don't use libunwind for IA64 register stack. (register_stack_extend): new function. (stack_extend): make it self-recursive with the stack position checking code in old rb_thread_restore_context. (rb_thread_restore_context): just call stack_extend. (flush_register_windows): removed. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@9745 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
