1385 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
1386 frame offset adjustment for out-of-line save with copy from sp.
1387 Simplify condition controlling whether cr is saved early or
1388 late. Use ptr_regno_for_savres to verify correct reg is set
1389 up for out-of-line saves. Pass the actual pointer reg used to
1390 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
1391 function. Rearrange spe vars so code is similar to that
1392 elsewhere in this function. Don't update frame_off when spe
1393 save code will restore r11. Use emit_frame_save for spe and
1394 gpr saves. Consolidate darwin out-of-line gpr setup with that
1395 for other abis. Don't assume frame_offset is zero and frame
1396 reg is sp when setting up altivec reg saves, and calculate
1397 exact offset requirement.
