494 of bitnum rather than offset, bitpos and byte_offset. Move the
495 computation of MODE1 to the block that needs it. Use MODE unless

497 plain move cases into two, one for memory accesses and one for
498 register accesses. Generalize the memory case, freeing it from
499 the old register-based endian checks. Move the INT_MODE calculation
500 above the code that needs it. Use simplify_gen_subreg to handle

503 that both targets and register sources fit within a word.

506 chosen unit size, rather than going through an intermediate
507 BITS_PER_WORD unit size. Simplify the containment check
508 used when forcing OP0 into a register. Update the call to

513 calculation and containment check for volatile bitfields. Make the
514 offset explicit when volatile bitfields force a misaligned access.

516 has an integral mode.

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