20281 frame offset adjustment for out-of-line save with copy from sp.
20282 Simplify condition controlling whether cr is saved early or
20283 late. Use ptr_regno_for_savres to verify correct reg is set
20284 up for out-of-line saves. Pass the actual pointer reg used to
20285 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
20286 function. Rearrange spe vars so code is similar to that
20287 elsewhere in this function. Don't update frame_off when spe
20288 save code will restore r11. Use emit_frame_save for spe and
20289 gpr saves. Consolidate darwin out-of-line gpr setup with that
20290 for other abis. Don't assume frame_offset is zero and frame
20291 reg is sp when setting up altivec reg saves, and calculate
20292 exact offset requirement.
