1538 extract_fixed_bit_field. In the big-endian case, always
1539 use the mode of OP0 to count the number of significant bits.
1540 (extract_bit_field_1): Remove unit, offset, bitpos and
1541 byte_offset from the outermost scope. Express conditions in terms
1542 of bitnum rather than offset, bitpos and byte_offset. Move the
1543 computation of MODE1 to the block that needs it. Use MODE unless
1544 the TMODE-based mode_for_size calculation succeeds. Split the
1545 plain move cases into two, one for memory accesses and one for
1546 register accesses. Generalize the memory case, freeing it from
1547 the old register-based endian checks. Move the INT_MODE calculation
1548 above the code that needs it. Use simplify_gen_subreg to handle
1549 multiword OP0s. If the field still spans several words, pass it
1550 directly to extract_split_bit_field. Assume after that point
1551 that both targets and register sources fit within a word.
1552 Replace x-prefixed variables with non-prefixed forms.
1553 Compute the bitpos for ext(z)v register operands directly in the
1554 chosen unit size, rather than going through an intermediate
1555 BITS_PER_WORD unit size. Simplify the containment check
1556 used when forcing OP0 into a register. Update the call to
1557 extract_fixed_bit_field.
1558 (extract_fixed_bit_field): Replace the bitpos and offset parameters
1559 with a single bitnum parameter, of the same form as extract_bit_field.
1560 Assume that OP0 contains the full field. Simplify the memory offset
1561 calculation and containment check for volatile bitfields. Make the
1562 offset explicit when volatile bitfields force a misaligned access.

1564 has an integral mode.

1576 to an integer mode. Use simplify_gen_subreg for this case and assert
1577 that it succeeds. If the field still spans several words, pass it
1578 directly to store_split_bit_field. Assume after that point that
1579 both sources and register targets fit within a word. Replace
