4806         (extract_bit_field_1): Remove unit, offset, bitpos and
4807         byte_offset from the outermost scope.  Express conditions in terms
4808         of bitnum rather than offset, bitpos and byte_offset.  Move the
4809         computation of MODE1 to the block that needs it.  Use MODE unless
4810         the TMODE-based mode_for_size calculation succeeds.  Split the

4813         the old register-based endian checks.  Move the INT_MODE calculation
4814         above the code that needs it.  Use simplify_gen_subreg to handle
4815         multiword OP0s.  If the field still spans several words, pass it
4816         directly to extract_split_bit_field.  Assume after that point

4821         BITS_PER_WORD unit size.  Simplify the containment check
4822         used when forcing OP0 into a register.  Update the call to

4824         (extract_fixed_bit_field): Replace the bitpos and offset parameters
4825         with a single bitnum parameter, of the same form as extract_bit_field.
4826         Assume that OP0 contains the full field.  Simplify the memory offset
4827         calculation and containment check for volatile bitfields.  Make the
4828         offset explicit when volatile bitfields force a misaligned access.
4829         Remove WARNED and fix long lines.  Assert that the processed OP0
4830         has an integral mode.
4831         (store_split_bit_field): Update the call to store_fixed_bit_field.

4839         cases into two, one for memory accesses and one for register accesses.
4840         Allow simplify_gen_subreg to fail rather than calling validate_subreg.
4841         Move the handling of multiword OP0s after the code that coerces VALUE
4842         to an integer mode.  Use simplify_gen_subreg for this case and assert
4843         that it succeeds.  If the field still spans several words, pass it
4844         directly to store_split_bit_field.  Assume after that point that
4845         both sources and register targets fit within a word.  Replace
4846         x-prefixed variables with non-prefixed forms.  Compute the bitpos
4847         for insv register operands directly in the chosen unit size, rather
4848         than going through an intermediate BITS_PER_WORD unit size.
4849         Update the call to store_fixed_bit_field.
4850         (store_fixed_bit_field): Replace the bitpos and offset parameters
