54 * expmed.c (store_split_bit_field): Update the calls to
55 extract_fixed_bit_field. In the big-endian case, always
56 use the mode of OP0 to count the number of significant bits.
57 (extract_bit_field_1): Remove unit, offset, bitpos and
58 byte_offset from the outermost scope. Express conditions in terms
59 of bitnum rather than offset, bitpos and byte_offset. Move the
60 computation of MODE1 to the block that needs it. Use MODE unless
61 the TMODE-based mode_for_size calculation succeeds. Split the
62 plain move cases into two, one for memory accesses and one for
63 register accesses. Generalize the memory case, freeing it from
64 the old register-based endian checks. Move the INT_MODE calculation
65 above the code that needs it. Use simplify_gen_subreg to handle
66 multiword OP0s. If the field still spans several words, pass it
67 directly to extract_split_bit_field. Assume after that point
68 that both targets and register sources fit within a word.
69 Replace x-prefixed variables with non-prefixed forms.
70 Compute the bitpos for ext(z)v register operands directly in the
71 chosen unit size, rather than going through an intermediate
72 BITS_PER_WORD unit size. Simplify the containment check
73 used when forcing OP0 into a register. Update the call to
74 extract_fixed_bit_field.
75 (extract_fixed_bit_field): Replace the bitpos and offset parameters
76 with a single bitnum parameter, of the same form as extract_bit_field.
77 Assume that OP0 contains the full field. Simplify the memory offset

79 offset explicit when volatile bitfields force a misaligned access.

91 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
92 Move the handling of multiword OP0s after the code that coerces VALUE
93 to an integer mode. Use simplify_gen_subreg for this case and assert
94 that it succeeds. If the field still spans several words, pass it
95 directly to store_split_bit_field. Assume after that point that
96 both sources and register targets fit within a word. Replace
