5634 from the outermost scope. Express conditions in terms of bitnum
5635 rather than offset, bitpos and byte_offset. Split the plain move
5636 cases into two, one for memory accesses and one for register accesses.
5637 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
5638 Move the handling of multiword OP0s after the code that coerces VALUE
5639 to an integer mode. Use simplify_gen_subreg for this case and assert
5640 that it succeeds. If the field still spans several words, pass it
5641 directly to store_split_bit_field. Assume after that point that
5642 both sources and register targets fit within a word. Replace
5643 x-prefixed variables with non-prefixed forms. Compute the bitpos
5644 for insv register operands directly in the chosen unit size, rather
5645 than going through an intermediate BITS_PER_WORD unit size.
5646 Update the call to store_fixed_bit_field.
5647 (store_fixed_bit_field): Replace the bitpos and offset parameters
5648 with a single bitnum parameter, of the same form as store_bit_field.
5649 Assume that OP0 contains the full field. Simplify the memory offset
5650 calculation. Assert that the processed OP0 has an integral mode.
5651 (store_split_bit_field): Update the call to store_fixed_bit_field.

26363 Set frame_reg_rtx to r11 whenever r11 is needed, and merge

26365 Simplify condition controlling whether cr is saved early or
26366 late. Use ptr_regno_for_savres to verify correct reg is set
26367 up for out-of-line saves. Pass the actual pointer reg used to
26368 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
26369 function. Rearrange spe vars so code is similar to that
26370 elsewhere in this function. Don't update frame_off when spe
26371 save code will restore r11. Use emit_frame_save for spe and
26372 gpr saves. Consolidate darwin out-of-line gpr setup with that
26373 for other abis. Don't assume frame_offset is zero and frame
26374 reg is sp when setting up altivec reg saves, and calculate
26375 exact offset requirement.
