191 of bitnum rather than offset, bitpos and byte_offset. Move the

193 the TMODE-based mode_for_size calculation succeeds. Split the
194 plain move cases into two, one for memory accesses and one for
195 register accesses. Generalize the memory case, freeing it from
196 the old register-based endian checks. Move the INT_MODE calculation
197 above the code that needs it. Use simplify_gen_subreg to handle
198 multiword OP0s. If the field still spans several words, pass it
