145 byte_offset from the outermost scope. Express conditions in terms
146 of bitnum rather than offset, bitpos and byte_offset. Move the
147 computation of MODE1 to the block that needs it. Use MODE unless
148 the TMODE-based mode_for_size calculation succeeds. Split the
149 plain move cases into two, one for memory accesses and one for
150 register accesses. Generalize the memory case, freeing it from
151 the old register-based endian checks. Move the INT_MODE calculation
152 above the code that needs it. Use simplify_gen_subreg to handle
153 multiword OP0s. If the field still spans several words, pass it
154 directly to extract_split_bit_field. Assume after that point
155 that both targets and register sources fit within a word.
156 Replace x-prefixed variables with non-prefixed forms.
157 Compute the bitpos for ext(z)v register operands directly in the
