      	* config/rs6000/rs6000.c (rs6000_savres_strategy): Allow
	out-of-line save/restore for large frames.  Don't disable
	out-of-line saves on ABI_AIX when using static chain reg.
	(rs6000_emit_prologue): Adjust cr_save_regno on ABI_AIX to not
	clobber static chain reg, and tweak for out-of-line gpr saves
	that use r1.

      	* config/rs6000/rs6000.c (rs6000_emit_stack_reset): Delete forward
	decl.  Move logic selecting update reg to callers.  Update all callers.
	(rs6000_emit_allocate_stack): Add copy_off param.
	(emit_frame_save): Don't handle reg+reg addressing.
	(ptr_regno_for_savres): New function, extracted from..
	(rs6000_emit_savres_rtx): ..here.  Add lr_offset param.
	(rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
	Set frame_reg_rtx to r11 whenever r11 is needed, and merge
	frame offset adjustment for out-of-line save with copy from sp.
	Simplify condition controlling whether cr is saved early or
	late.  Use ptr_regno_for_savres to verify correct reg is set
	up for out-of-line saves.  Pass the actual pointer reg used to
	rs6000_emit_savres_rtx so rtl matches insns in out-of-line
	function.  Rearrange spe vars so code is similar to that
	elsewhere in this function.  Don't update frame_off when spe
	save code will restore r11.  Use emit_frame_save for spe and
	gpr saves.  Consolidate darwin out-of-line gpr setup with that
	for other abis.  Don't assume frame_offset is zero and frame
	reg is sp when setting up altivec reg saves, and calculate
	exact offset requirement.
	(rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off.  Tidy
	spe restore code.  Consolidate darwin out-of-line gpr setup
	with that for other abis.
