26817 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
26818 frame offset adjustment for out-of-line save with copy from sp.
26819 Simplify condition controlling whether cr is saved early or
26820 late. Use ptr_regno_for_savres to verify correct reg is set
26821 up for out-of-line saves. Pass the actual pointer reg used to
26822 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
26823 function. Rearrange spe vars so code is similar to that
26824 elsewhere in this function. Don't update frame_off when spe
26825 save code will restore r11. Use emit_frame_save for spe and
26826 gpr saves. Consolidate darwin out-of-line gpr setup with that
26827 for other abis. Don't assume frame_offset is zero and frame
26828 reg is sp when setting up altivec reg saves, and calculate
26829 exact offset requirement.
26830 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
26831 spe restore code. Consolidate darwin out-of-line gpr setup
