* configure.in: define IA64 for portability. (HP aC++/ANSI C doesn't
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.
