4731 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
4732 from the outermost scope. Express conditions in terms of bitnum
4733 rather than offset, bitpos and byte_offset. Split the plain move
4734 cases into two, one for memory accesses and one for register accesses.
4735 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
4736 Move the handling of multiword OP0s after the code that coerces VALUE
4737 to an integer mode. Use simplify_gen_subreg for this case and assert
4738 that it succeeds. If the field still spans several words, pass it
4739 directly to store_split_bit_field. Assume after that point that
4740 both sources and register targets fit within a word. Replace
4741 x-prefixed variables with non-prefixed forms. Compute the bitpos
4742 for insv register operands directly in the chosen unit size, rather
4743 than going through an intermediate BITS_PER_WORD unit size.
4744 Update the call to store_fixed_bit_field.
4745 (store_fixed_bit_field): Replace the bitpos and offset parameters
4746 with a single bitnum parameter, of the same form as store_bit_field.
4747 Assume that OP0 contains the full field. Simplify the memory offset
4748 calculation. Assert that the processed OP0 has an integral mode.
4749 (store_split_bit_field): Update the call to store_fixed_bit_field.

25462 frame offset adjustment for out-of-line save with copy from sp.
25463 Simplify condition controlling whether cr is saved early or
25464 late. Use ptr_regno_for_savres to verify correct reg is set
25465 up for out-of-line saves. Pass the actual pointer reg used to
25466 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
25467 function. Rearrange spe vars so code is similar to that
25468 elsewhere in this function. Don't update frame_off when spe
25469 save code will restore r11. Use emit_frame_save for spe and
25470 gpr saves. Consolidate darwin out-of-line gpr setup with that
25471 for other abis. Don't assume frame_offset is zero and frame
25472 reg is sp when setting up altivec reg saves, and calculate
25473 exact offset requirement.
25474 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
25475 spe restore code. Consolidate darwin out-of-line gpr setup
25476 with that for other abis.
