6138 calculation and containment check for volatile bitfields. Make the
6139 offset explicit when volatile bitfields force a misaligned access.
6140 Remove WARNED and fix long lines. Assert that the processed OP0
6141 has an integral mode.

6146 * expmed.c (lowpart_bit_field_p): New function.
6147 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
6148 from the outermost scope. Express conditions in terms of bitnum
6149 rather than offset, bitpos and byte_offset. Split the plain move
6150 cases into two, one for memory accesses and one for register accesses.
6151 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
6152 Move the handling of multiword OP0s after the code that coerces VALUE
6153 to an integer mode. Use simplify_gen_subreg for this case and assert
6154 that it succeeds. If the field still spans several words, pass it
6155 directly to store_split_bit_field. Assume after that point that
6156 both sources and register targets fit within a word. Replace
6157 x-prefixed variables with non-prefixed forms. Compute the bitpos
6158 for insv register operands directly in the chosen unit size, rather
6159 than going through an intermediate BITS_PER_WORD unit size.
6160 Update the call to store_fixed_bit_field.
6161 (store_fixed_bit_field): Replace the bitpos and offset parameters
6162 with a single bitnum parameter, of the same form as store_bit_field.
6163 Assume that OP0 contains the full field. Simplify the memory offset
6164 calculation. Assert that the processed OP0 has an integral mode.
6165 (store_split_bit_field): Update the call to store_fixed_bit_field.

26837 and using_store_multiple. Expand uses. Don't always use r11 as
26838 frame reg when needed for out-of-line saves. Set up initial offset
26839 for out-of-line vector saves when buying stack frame. Handle pointer
26840 reg setup for out-of-line fp save. Emit call to out-of-line vector
26841 save function. Choose r11 or r12 for vrsave reg when available for

26844 (rs6000_emit_epilogue): Choose a better frame reg when restoring
26845 from back-chain to suit out-of-line vector restore functions. Emit
26846 call to out-of-line vector restore function. Adjust register used
26847 for cr restore. Tweak pointer register setup for gpr restore.

26877 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
26878 frame offset adjustment for out-of-line save with copy from sp.
26879 Simplify condition controlling whether cr is saved early or
26880 late. Use ptr_regno_for_savres to verify correct reg is set
26881 up for out-of-line saves. Pass the actual pointer reg used to
26882 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
26883 function. Rearrange spe vars so code is similar to that
26884 elsewhere in this function. Don't update frame_off when spe
26885 save code will restore r11. Use emit_frame_save for spe and
26886 gpr saves. Consolidate darwin out-of-line gpr setup with that
26887 for other abis. Don't assume frame_offset is zero and frame
26888 reg is sp when setting up altivec reg saves, and calculate
26889 exact offset requirement.
26890 (rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
26891 spe restore code. Consolidate darwin out-of-line gpr setup
