18954 and using_store_multiple. Expand uses. Don't always use r11 as
18955 frame reg when needed for out-of-line saves. Set up initial offset
18956 for out-of-line vector saves when buying stack frame. Handle pointer
18957 reg setup for out-of-line fp save. Emit call to out-of-line vector
18958 save function. Choose r11 or r12 for vrsave reg when available for

18961 (rs6000_emit_epilogue): Choose a better frame reg when restoring
18962 from back-chain to suit out-of-line vector restore functions. Emit
18963 call to out-of-line vector restore function. Adjust register used
18964 for cr restore. Tweak pointer register setup for gpr restore.

18994 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
18995 frame offset adjustment for out-of-line save with copy from sp.
18996 Simplify condition controlling whether cr is saved early or
18997 late. Use ptr_regno_for_savres to verify correct reg is set
18998 up for out-of-line saves. Pass the actual pointer reg used to
18999 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
19000 function. Rearrange spe vars so code is similar to that
19001 elsewhere in this function. Don't update frame_off when spe
19002 save code will restore r11. Use emit_frame_save for spe and
19003 gpr saves. Consolidate darwin out-of-line gpr setup with that
19004 for other abis. Don't assume frame_offset is zero and frame
19005 reg is sp when setting up altivec reg saves, and calculate
19006 exact offset requirement.
19007 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
19008 spe restore code. Consolidate darwin out-of-line gpr setup
