2012-10-23expmed.c (store_split_bit_field): Update the calls to extract_fixed_bit_field.Richard Sandiford2-214/+183
gcc/ * expmed.c (store_split_bit_field): Update the calls to extract_fixed_bit_field. In the big-endian case, always use the mode of OP0 to count the number of significant bits. (extract_bit_field_1): Remove unit, offset, bitpos and byte_offset from the outermost scope. Express conditions in terms of bitnum rather than offset, bitpos and byte_offset. Move the computation of MODE1 to the block that needs it. Use MODE unless the TMODE-based mode_for_size calculation succeeds. Split the plain move cases into two, one for memory accesses and one for register accesses. Generalize the memory case, freeing it from the old register-based endian checks. Move the INT_MODE calculation above the code that needs it. Use simplify_gen_subreg to handle multiword OP0s. If the field still spans several words, pass it directly to extract_split_bit_field. Assume after that point that both targets and register sources fit within a word. Replace x-prefixed variables with non-prefixed forms. Compute the bitpos for ext(z)v register operands directly in the chosen unit size, rather than going through an intermediate BITS_PER_WORD unit size. Simplify the containment check used when forcing OP0 into a register. Update the call to extract_fixed_bit_field. (extract_fixed_bit_field): Replace the bitpos and offset parameters with a single bitnum parameter, of the same form as extract_bit_field. Assume that OP0 contains the full field. Simplify the memory offset calculation and containment check for volatile bitfields. Make the offset explicit when volatile bitfields force a misaligned access. Remove WARNED and fix long lines. Assert that the processed OP0 has an integral mode. (store_split_bit_field): Update the call to store_fixed_bit_field. From-SVN: r192741

Express conditions in terms of bitnum rather than offset, bitpos and byte_offset. Split the plain move cases into two, one for memory accesses and one for register accesses. Allow simplify_gen_subreg to fail rather than calling validate_subreg. Move the handling of multiword OP0s after the code that coerces VALUE to an integer mode. Use simplify_gen_subreg for this case and assert that it succeeds. If the field still spans several words, pass it directly to store_split_bit_field. Assume after that point that both sources and register targets fit within a word. Replace x-prefixed variables with non-prefixed forms. Compute the bitpos for insv register operands directly in the chosen unit size, rather than going through an intermediate BITS_PER_WORD unit size. Update the call to store_fixed_bit_field.
