7214 (rs6000_emit_savres_rtx): ..here. Add lr_offset param.
7215 (rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
7216 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
7217 frame offset adjustment for out-of-line save with copy from sp.
7218 Simplify condition controlling whether cr is saved early or
7219 late. Use ptr_regno_for_savres to verify correct reg is set
7220 up for out-of-line saves. Pass the actual pointer reg used to
7221 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7222 function. Rearrange spe vars so code is similar to that
7223 elsewhere in this function. Don't update frame_off when spe
7224 save code will restore r11. Use emit_frame_save for spe and
7225 gpr saves. Consolidate darwin out-of-line gpr setup with that
7226 for other abis. Don't assume frame_offset is zero and frame
7227 reg is sp when setting up altivec reg saves, and calculate
7228 exact offset requirement.
7229 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
7230 spe restore code. Consolidate darwin out-of-line gpr setup
7231 with that for other abis.
