18084 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
18085 frame offset adjustment for out-of-line save with copy from sp.
18086 Simplify condition controlling whether cr is saved early or
18087 late. Use ptr_regno_for_savres to verify correct reg is set
18088 up for out-of-line saves. Pass the actual pointer reg used to
18089 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
18090 function. Rearrange spe vars so code is similar to that
18091 elsewhere in this function. Don't update frame_off when spe
18092 save code will restore r11. Use emit_frame_save for spe and
18093 gpr saves. Consolidate darwin out-of-line gpr setup with that
18094 for other abis. Don't assume frame_offset is zero and frame
18095 reg is sp when setting up altivec reg saves, and calculate
18096 exact offset requirement.
18097 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
18098 spe restore code. Consolidate darwin out-of-line gpr setup
