Subject: rs6000: float128 on BE and 32-bit

This fixes float128 on BE and on 32-bit.

The configure tests need to use -mabi=altivec for 32-bit, since it is
not the default there.  That also enables the "vector" keyword, used by
the tests.  To do this it temporarily adds a few flags to the CFLAGS
variable.

It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test
(the function name was missing in the function declaration).

Regenerating config.in (via autoreconf) removed the duplicate definition
of HAVE_SOLARIS_CRTS.

Finally, this adds a "-mfloat128-hardware requires -m64" test to
rs6000.c: all the current patterns need 64-bit registers.  Maybe we'll
want to add float128 hardware support to 32-bit some day, but certainly
not today.


	* config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow
	-mfloat128-hardware without -m64.

libgcc/
	* configure.ac (test for libgcc_cv_powerpc_float128): Temporarily
	modify CFLAGS.  Add -mabi=altivec -mvsx -mfloat128.
	(test for libgcc_cv_powerpc_float128_hw): Add -mpower9-vector and
	-mfloat128-hardware to the CFLAGS.  Fix syntax error in the C snippet.
	* configure: Regenerate.
	* config.in: Regenerate.

Subject: Build crt*vr.S with AltiVec enabled

These files won't build on targets that do not have AltiVec enabled,
breaking the build, unless we tell GAS that Altivec insns are fine.
The alternative is to not build these files in that case, which is much
more complicated.

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_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.
