Wed Sep 1 21:13:48 1999 Richard Henderson <rth@cygnus.com>
Merge new ia32 backend from the branch!
* i386.h, i386.c, i386.md, reg-stack.c, i386/unix.h: Many changes.
See ChangeLog.P2 on new_ia32_branch for details.
* rtl.h (stack_regs_mentioned_p): Delete prototype.
* i386/cygwin.h (SUBTARGET_PROLOGUE): No more do_rtl.
* i386/win32.h (SUBTARGET_PROLOGUE): Likewise.
* i386/gas.h (ASM_FILE_START): Define.
* i386/winnt.c (i386_pe_valid_decl_attribute_p): Update
for name change of ix86_valid_decl_attribute_p.
(i386_pe_valid_type_attribute_p): Similarly.
Wed Sep 1 18:21:23 1999 Richard Henderson <rth@cygnus.com>
* emit-rtl.c (init_emit_once): Don't use GET_MODE_WIDER_MODE
