14613 and using_store_multiple. Expand uses. Don't always use r11 as
14614 frame reg when needed for out-of-line saves. Set up initial offset
14615 for out-of-line vector saves when buying stack frame. Handle pointer
14616 reg setup for out-of-line fp save. Emit call to out-of-line vector
14617 save function. Choose r11 or r12 for vrsave reg when available for

14621 from back-chain to suit out-of-line vector restore functions. Emit
14622 call to out-of-line vector restore function. Adjust register used

14653 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
14654 frame offset adjustment for out-of-line save with copy from sp.
14655 Simplify condition controlling whether cr is saved early or
14656 late. Use ptr_regno_for_savres to verify correct reg is set
14657 up for out-of-line saves. Pass the actual pointer reg used to
14658 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
14659 function. Rearrange spe vars so code is similar to that
14660 elsewhere in this function. Don't update frame_off when spe
14661 save code will restore r11. Use emit_frame_save for spe and
14662 gpr saves. Consolidate darwin out-of-line gpr setup with that
14663 for other abis. Don't assume frame_offset is zero and frame
14664 reg is sp when setting up altivec reg saves, and calculate
14665 exact offset requirement.
14666 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
14667 spe restore code. Consolidate darwin out-of-line gpr setup
