269 (extract_bit_field_1): Remove unit, offset, bitpos and
270 byte_offset from the outermost scope. Express conditions in terms
271 of bitnum rather than offset, bitpos and byte_offset. Move the
272 computation of MODE1 to the block that needs it. Use MODE unless
273 the TMODE-based mode_for_size calculation succeeds. Split the
274 plain move cases into two, one for memory accesses and one for
275 register accesses. Generalize the memory case, freeing it from
276 the old register-based endian checks. Move the INT_MODE calculation
277 above the code that needs it. Use simplify_gen_subreg to handle
278 multiword OP0s. If the field still spans several words, pass it
279 directly to extract_split_bit_field. Assume after that point
280 that both targets and register sources fit within a word.
281 Replace x-prefixed variables with non-prefixed forms.
282 Compute the bitpos for ext(z)v register operands directly in the
283 chosen unit size, rather than going through an intermediate
284 BITS_PER_WORD unit size. Simplify the containment check
285 used when forcing OP0 into a register. Update the call to
