18073 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
18074 frame offset adjustment for out-of-line save with copy from sp.
18075 Simplify condition controlling whether cr is saved early or
18076 late. Use ptr_regno_for_savres to verify correct reg is set
18077 up for out-of-line saves. Pass the actual pointer reg used to
18078 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
18079 function. Rearrange spe vars so code is similar to that
18080 elsewhere in this function. Don't update frame_off when spe
18081 save code will restore r11. Use emit_frame_save for spe and
18082 gpr saves. Consolidate darwin out-of-line gpr setup with that
18083 for other abis. Don't assume frame_offset is zero and frame
18084 reg is sp when setting up altivec reg saves, and calculate
18085 exact offset requirement.
