520 * expmed.c (lowpart_bit_field_p): New function.
521 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
522 from the outermost scope. Express conditions in terms of bitnum
523 rather than offset, bitpos and byte_offset. Split the plain move
524 cases into two, one for memory accesses and one for register accesses.
525 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
526 Move the handling of multiword OP0s after the code that coerces VALUE
527 to an integer mode. Use simplify_gen_subreg for this case and assert
528 that it succeeds. If the field still spans several words, pass it
529 directly to store_split_bit_field. Assume after that point that
530 both sources and register targets fit within a word. Replace
531 x-prefixed variables with non-prefixed forms. Compute the bitpos
532 for insv register operands directly in the chosen unit size, rather
533 than going through an intermediate BITS_PER_WORD unit size.
534 Update the call to store_fixed_bit_field.
535 (store_fixed_bit_field): Replace the bitpos and offset parameters
536 with a single bitnum parameter, of the same form as store_bit_field.
537 Assume that OP0 contains the full field. Simplify the memory offset
538 calculation. Assert that the processed OP0 has an integral mode.
539 (store_split_bit_field): Update the call to store_fixed_bit_field.
