2775 Simplify condition controlling whether cr is saved early or
2776 late. Use ptr_regno_for_savres to verify correct reg is set
2777 up for out-of-line saves. Pass the actual pointer reg used to
2778 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
2779 function. Rearrange spe vars so code is similar to that
2780 elsewhere in this function. Don't update frame_off when spe
2781 save code will restore r11. Use emit_frame_save for spe and
2782 gpr saves. Consolidate darwin out-of-line gpr setup with that

2784 reg is sp when setting up altivec reg saves, and calculate
2785 exact offset requirement.
