2697 (rs6000_emit_savres_rtx): ..here. Add lr_offset param.
2698 (rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
2699 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
2700 frame offset adjustment for out-of-line save with copy from sp.
2701 Simplify condition controlling whether cr is saved early or
2702 late. Use ptr_regno_for_savres to verify correct reg is set
2703 up for out-of-line saves. Pass the actual pointer reg used to
2704 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
2705 function. Rearrange spe vars so code is similar to that
2706 elsewhere in this function. Don't update frame_off when spe
2707 save code will restore r11. Use emit_frame_save for spe and
2708 gpr saves. Consolidate darwin out-of-line gpr setup with that
2709 for other abis. Don't assume frame_offset is zero and frame
2710 reg is sp when setting up altivec reg saves, and calculate
2711 exact offset requirement.
2712 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
2713 spe restore code. Consolidate darwin out-of-line gpr setup
