532 from thread_across_edge.

540 2012-10-23 Richard Sandiford <rdsandiford@googlemail.com>
542 * expmed.c (store_split_bit_field): Update the calls to
543 extract_fixed_bit_field. In the big-endian case, always
544 use the mode of OP0 to count the number of significant bits.
545 (extract_bit_field_1): Remove unit, offset, bitpos and
546 byte_offset from the outermost scope. Express conditions in terms
547 of bitnum rather than offset, bitpos and byte_offset. Move the
548 computation of MODE1 to the block that needs it. Use MODE unless
549 the TMODE-based mode_for_size calculation succeeds. Split the
550 plain move cases into two, one for memory accesses and one for
551 register accesses. Generalize the memory case, freeing it from
552 the old register-based endian checks. Move the INT_MODE calculation
553 above the code that needs it. Use simplify_gen_subreg to handle
554 multiword OP0s. If the field still spans several words, pass it
555 directly to extract_split_bit_field. Assume after that point
556 that both targets and register sources fit within a word.
557 Replace x-prefixed variables with non-prefixed forms.
558 Compute the bitpos for ext(z)v register operands directly in the
559 chosen unit size, rather than going through an intermediate
560 BITS_PER_WORD unit size. Simplify the containment check
561 used when forcing OP0 into a register. Update the call to
562 extract_fixed_bit_field.
563 (extract_fixed_bit_field): Replace the bitpos and offset parameters
564 with a single bitnum parameter, of the same form as extract_bit_field.
565 Assume that OP0 contains the full field. Simplify the memory offset
566 calculation and containment check for volatile bitfields. Make the
567 offset explicit when volatile bitfields force a misaligned access.
568 Remove WARNED and fix long lines. Assert that the processed OP0
569 has an integral mode.
570 (store_split_bit_field): Update the call to store_fixed_bit_field.

574 * expmed.c (lowpart_bit_field_p): New function.
575 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
576 from the outermost scope. Express conditions in terms of bitnum
577 rather than offset, bitpos and byte_offset. Split the plain move
578 cases into two, one for memory accesses and one for register accesses.
579 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
580 Move the handling of multiword OP0s after the code that coerces VALUE
581 to an integer mode. Use simplify_gen_subreg for this case and assert
582 that it succeeds. If the field still spans several words, pass it
583 directly to store_split_bit_field. Assume after that point that
584 both sources and register targets fit within a word. Replace
585 x-prefixed variables with non-prefixed forms. Compute the bitpos
586 for insv register operands directly in the chosen unit size, rather
587 than going through an intermediate BITS_PER_WORD unit size.
588 Update the call to store_fixed_bit_field.
589 (store_fixed_bit_field): Replace the bitpos and offset parameters
590 with a single bitnum parameter, of the same form as store_bit_field.
591 Assume that OP0 contains the full field. Simplify the memory offset
592 calculation. Assert that the processed OP0 has an integral mode.
