2723 (rs6000_emit_savres_rtx): ..here. Add lr_offset param.
2724 (rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
2725 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
2726 frame offset adjustment for out-of-line save with copy from sp.
2727 Simplify condition controlling whether cr is saved early or
2728 late. Use ptr_regno_for_savres to verify correct reg is set
2729 up for out-of-line saves. Pass the actual pointer reg used to
2730 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
2731 function. Rearrange spe vars so code is similar to that
2732 elsewhere in this function. Don't update frame_off when spe
2733 save code will restore r11. Use emit_frame_save for spe and
2734 gpr saves. Consolidate darwin out-of-line gpr setup with that
2735 for other abis. Don't assume frame_offset is zero and frame
2736 reg is sp when setting up altivec reg saves, and calculate
2737 exact offset requirement.
2738 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
2739 spe restore code. Consolidate darwin out-of-line gpr setup
