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. (restore_multiple_and_return<mode>): Likewise. (restore_multiple_leave_return<mode>): Likewise. * Makefile.in: Export HOSTCXX and HOSTCXXFLAGS to site.exp gcc/testsuite/ChangeLog: * gcc.target/x86_64/abi/ms-sysv/do-test.S: New file. * gcc.target/x86_64/abi/ms-sysv/gen.cc: Likewise. * gcc.target/x86_64/abi/ms-sysv/ms-sysv.c: Likewise. * gcc.target/x86_64/abi/ms-sysv/ms-sysv.exp: Likewise. libgcc/ChangeLog: * config.host: Add i386/t-msabi to i386/t-linux file list. * config/i386/i386-asm.h: New file. * config/i386/resms64.S: New file. * config/i386/resms64f.S: New file. * config/i386/resms64fx.S: New file. * config/i386/resms64x.S: New file. * config/i386/savms64.S: New file. * config/i386/savms64f.S: New file. * config/i386/t-msabi: New file.
