13729 frame offset adjustment for out-of-line save with copy from sp.
13730 Simplify condition controlling whether cr is saved early or
13731 late. Use ptr_regno_for_savres to verify correct reg is set
13732 up for out-of-line saves. Pass the actual pointer reg used to
13733 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
13734 function. Rearrange spe vars so code is similar to that
13735 elsewhere in this function. Don't update frame_off when spe
13736 save code will restore r11. Use emit_frame_save for spe and
13737 gpr saves. Consolidate darwin out-of-line gpr setup with that
13738 for other abis. Don't assume frame_offset is zero and frame
13739 reg is sp when setting up altivec reg saves, and calculate
13740 exact offset requirement.
13741 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
13742 spe restore code. Consolidate darwin out-of-line gpr setup
13743 with that for other abis.
