2720 (rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
2721 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
2722 frame offset adjustment for out-of-line save with copy from sp.
2723 Simplify condition controlling whether cr is saved early or
2724 late. Use ptr_regno_for_savres to verify correct reg is set
2725 up for out-of-line saves. Pass the actual pointer reg used to
2726 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
2727 function. Rearrange spe vars so code is similar to that
2728 elsewhere in this function. Don't update frame_off when spe
2729 save code will restore r11. Use emit_frame_save for spe and
2730 gpr saves. Consolidate darwin out-of-line gpr setup with that
2731 for other abis. Don't assume frame_offset is zero and frame
2732 reg is sp when setting up altivec reg saves, and calculate
2733 exact offset requirement.
2734 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
2735 spe restore code. Consolidate darwin out-of-line gpr setup
