gcc/ChangeLog:
* config/i386/i386.opt: Add option -mcall-ms2sysv-xlogues.
* config/i386/i386.h
(x86_64_ms_sysv_extra_clobbered_registers): Change type to unsigned.
(NUM_X86_64_MS_CLOBBERED_REGS): New macro.
(struct machine_function): Add new members call_ms2sysv,
call_ms2sysv_pad_in, call_ms2sysv_pad_out and call_ms2sysv_extra_regs.
(struct machine_frame_state): New fields sp_realigned and
sp_realigned_offset.
* config/i386/i386.c
(enum xlogue_stub): New enum.
(enum xlogue_stub_sets): New enum.
(class xlogue_layout): New class.
(struct ix86_frame): New fields stack_realign_allocate_offset,
stack_realign_offset and outlined_save_offset. Modify comments to
detail stack layout when using out-of-line stubs.
(ix86_target_string): Add -mcall-ms2sysv-xlogues option.
(ix86_option_override_internal): Add sorry() for TARGET_SEH and
-mcall-ms2sysv-xlogues.
(stub_managed_regs): New static variable.
(ix86_save_reg): Add new parameter ignore_outlined to optionally omit
registers managed by out-of-line stub.
(disable_call_ms2sysv_xlogues): New function.
(ix86_compute_frame_layout): Modify re-alignment calculations, disable
m->call_ms2sysv when appropriate and compute frame layout for
out-of-line stubs.
(sp_valid_at, fp_valid_at): New inline functions.
(choose_basereg): New function.
(choose_baseaddr): Add align parameter, use choose_basereg and modify
all callers.
(ix86_emit_save_reg_using_mov, ix86_emit_restore_sse_regs_using_mov):
Use align parameter of choose_baseaddr to generated aligned SSE movs
when possible.
(pro_epilogue_adjust_stack): Modify to track
machine_frame_state::sp_realigned.
(ix86_nsaved_regs): Modify to accommodate changes to ix86_save_reg.
(ix86_nsaved_sseregs): Likewise.
(ix86_emit_save_regs): Likewise.
(ix86_emit_save_regs_using_mov): Likewise.
(ix86_emit_save_sse_regs_using_mov): Likewise.
(get_scratch_register_on_entry): Likewise.
(gen_frame_set): New function.
(gen_frame_load): Likewise.
(gen_frame_store): Likewise.
(emit_outlined_ms2sysv_save): Likewise.
(emit_outlined_ms2sysv_restore): Likewise.
(ix86_expand_prologue): Modify stack re-alignment code and call
emit_outlined_ms2sysv_save when appropriate.
(ix86_emit_leave): Clear machine_frame_state::sp_realigned. Add
parameter rtx_insn *insn, which allows the function to be used to only
generate the notes.
(ix86_expand_epilogue): Modify validity checks of frame and stack
pointers, and call emit_outlined_ms2sysv_restore when appropriate.
(ix86_expand_call): Modify to enable m->call_ms2sysv when appropriate.
* config/i386/predicates.md
(save_multiple): New predicate.
(restore_multiple): Likewise.
* config/i386/sse.md
(save_multiple<mode>): New pattern.
(save_multiple_realign<mode>): Likewise.
(restore_multiple<mode>): Likewise.
