3855 * expmed.c (store_split_bit_field): Update the calls to
3856 extract_fixed_bit_field. In the big-endian case, always
3857 use the mode of OP0 to count the number of significant bits.
3858 (extract_bit_field_1): Remove unit, offset, bitpos and
3859 byte_offset from the outermost scope. Express conditions in terms
3860 of bitnum rather than offset, bitpos and byte_offset. Move the
3861 computation of MODE1 to the block that needs it. Use MODE unless
3862 the TMODE-based mode_for_size calculation succeeds. Split the
3863 plain move cases into two, one for memory accesses and one for
3864 register accesses. Generalize the memory case, freeing it from
3865 the old register-based endian checks. Move the INT_MODE calculation
3866 above the code that needs it. Use simplify_gen_subreg to handle
3867 multiword OP0s. If the field still spans several words, pass it
3868 directly to extract_split_bit_field. Assume after that point
3869 that both targets and register sources fit within a word.
3870 Replace x-prefixed variables with non-prefixed forms.
3871 Compute the bitpos for ext(z)v register operands directly in the
3872 chosen unit size, rather than going through an intermediate
3873 BITS_PER_WORD unit size. Simplify the containment check
3874 used when forcing OP0 into a register. Update the call to
3875 extract_fixed_bit_field.
3876 (extract_fixed_bit_field): Replace the bitpos and offset parameters
3877 with a single bitnum parameter, of the same form as extract_bit_field.
3878 Assume that OP0 contains the full field. Simplify the memory offset
3879 calculation and containment check for volatile bitfields. Make the
3880 offset explicit when volatile bitfields force a misaligned access.
3881 Remove WARNED and fix long lines. Assert that the processed OP0
3882 has an integral mode.
3883 (store_split_bit_field): Update the call to store_fixed_bit_field.

3888 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
3889 from the outermost scope. Express conditions in terms of bitnum
3890 rather than offset, bitpos and byte_offset. Split the plain move
3891 cases into two, one for memory accesses and one for register accesses.
3892 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
3893 Move the handling of multiword OP0s after the code that coerces VALUE
3894 to an integer mode. Use simplify_gen_subreg for this case and assert
3895 that it succeeds. If the field still spans several words, pass it
3896 directly to store_split_bit_field. Assume after that point that
3897 both sources and register targets fit within a word. Replace
3898 x-prefixed variables with non-prefixed forms. Compute the bitpos
3899 for insv register operands directly in the chosen unit size, rather
3900 than going through an intermediate BITS_PER_WORD unit size.
3901 Update the call to store_fixed_bit_field.
3902 (store_fixed_bit_field): Replace the bitpos and offset parameters
3903 with a single bitnum parameter, of the same form as store_bit_field.
3904 Assume that OP0 contains the full field. Simplify the memory offset
3905 calculation. Assert that the processed OP0 has an integral mode.

24616 (rs6000_emit_savres_rtx): ..here. Add lr_offset param.

24618 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
24619 frame offset adjustment for out-of-line save with copy from sp.
24620 Simplify condition controlling whether cr is saved early or
24621 late. Use ptr_regno_for_savres to verify correct reg is set
24622 up for out-of-line saves. Pass the actual pointer reg used to
24623 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
24624 function. Rearrange spe vars so code is similar to that
24625 elsewhere in this function. Don't update frame_off when spe
24626 save code will restore r11. Use emit_frame_save for spe and
24627 gpr saves. Consolidate darwin out-of-line gpr setup with that
24628 for other abis. Don't assume frame_offset is zero and frame
24629 reg is sp when setting up altivec reg saves, and calculate
24630 exact offset requirement.
