1447 Simplify condition controlling whether cr is saved early or
1448 late. Use ptr_regno_for_savres to verify correct reg is set
1449 up for out-of-line saves. Pass the actual pointer reg used to
1450 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
1451 function. Rearrange spe vars so code is similar to that
1452 elsewhere in this function. Don't update frame_off when spe
1453 save code will restore r11. Use emit_frame_save for spe and
1454 gpr saves. Consolidate darwin out-of-line gpr setup with that

1456 reg is sp when setting up altivec reg saves, and calculate
1457 exact offset requirement.
