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. + (store_fixed_bit_field): Replace the bitpos and offset parameters + with a single bitnum parameter, of the same form as store_bit_field. + Assume that OP0 contains the full field. Simplify the memory offset + calculation. Assert that the processed OP0 has an integral mode. + (store_split_bit_field): Update the call to store_fixed_bit_field. + 2012-10-23 Paul Koning <ni1d@arrl.net> PR debug/54508 |
