4789 extract_fixed_bit_field. In the big-endian case, always
4790 use the mode of OP0 to count the number of significant bits.
4791 (extract_bit_field_1): Remove unit, offset, bitpos and
4792 byte_offset from the outermost scope. Express conditions in terms
4793 of bitnum rather than offset, bitpos and byte_offset. Move the
4794 computation of MODE1 to the block that needs it. Use MODE unless
4795 the TMODE-based mode_for_size calculation succeeds. Split the
4796 plain move cases into two, one for memory accesses and one for
4797 register accesses. Generalize the memory case, freeing it from
4798 the old register-based endian checks. Move the INT_MODE calculation
4799 above the code that needs it. Use simplify_gen_subreg to handle
4800 multiword OP0s. If the field still spans several words, pass it
4801 directly to extract_split_bit_field. Assume after that point
4802 that both targets and register sources fit within a word.
4803 Replace x-prefixed variables with non-prefixed forms.
4804 Compute the bitpos for ext(z)v register operands directly in the
4805 chosen unit size, rather than going through an intermediate
4806 BITS_PER_WORD unit size. Simplify the containment check
4807 used when forcing OP0 into a register. Update the call to
4808 extract_fixed_bit_field.
4809 (extract_fixed_bit_field): Replace the bitpos and offset parameters
4810 with a single bitnum parameter, of the same form as extract_bit_field.
4811 Assume that OP0 contains the full field. Simplify the memory offset
4812 calculation and containment check for volatile bitfields. Make the
4813 offset explicit when volatile bitfields force a misaligned access.

4815 has an integral mode.

4827 to an integer mode. Use simplify_gen_subreg for this case and assert
4828 that it succeeds. If the field still spans several words, pass it
4829 directly to store_split_bit_field. Assume after that point that
4830 both sources and register targets fit within a word. Replace
