19378 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
19379 frame offset adjustment for out-of-line save with copy from sp.
19380 Simplify condition controlling whether cr is saved early or
19381 late. Use ptr_regno_for_savres to verify correct reg is set
19382 up for out-of-line saves. Pass the actual pointer reg used to
19383 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
19384 function. Rearrange spe vars so code is similar to that
19385 elsewhere in this function. Don't update frame_off when spe
19386 save code will restore r11. Use emit_frame_save for spe and
19387 gpr saves. Consolidate darwin out-of-line gpr setup with that
19388 for other abis. Don't assume frame_offset is zero and frame
19389 reg is sp when setting up altivec reg saves, and calculate
19390 exact offset requirement.
19391 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
19392 spe restore code. Consolidate darwin out-of-line gpr setup
