    • expmed.c (store_split_bit_field): Update the calls to extract_fixed_bit_field. · b8ab7fc8 
      gcc/
	* expmed.c (store_split_bit_field): Update the calls to
	extract_fixed_bit_field.  In the big-endian case, always
	use the mode of OP0 to count the number of significant bits.
	(extract_bit_field_1): Remove unit, offset, bitpos and
	byte_offset from the outermost scope.  Express conditions in terms
	of bitnum rather than offset, bitpos and byte_offset.  Move the
	computation of MODE1 to the block that needs it.  Use MODE unless
	the TMODE-based mode_for_size calculation succeeds.  Split the
	plain move cases into two, one for memory accesses and one for
	register accesses.  Generalize the memory case, freeing it from
	the old register-based endian checks.  Move the INT_MODE calculation
	above the code that needs it.  Use simplify_gen_subreg to handle
	multiword OP0s.  If the field still spans several words, pass it
	directly to extract_split_bit_field.  Assume after that point
	that both targets and register sources fit within a word.
	Replace x-prefixed variables with non-prefixed forms.
	Compute the bitpos for ext(z)v register operands directly in the
	chosen unit size, rather than going through an intermediate
	BITS_PER_WORD unit size.  Simplify the containment check
	used when forcing OP0 into a register.  Update the call to
	extract_fixed_bit_field.
	(extract_fixed_bit_field): Replace the bitpos and offset parameters
	with a single bitnum parameter, of the same form as extract_bit_field.
	Assume that OP0 contains the full field.  Simplify the memory offset
	calculation and containment check for volatile bitfields.  Make the
	offset explicit when volatile bitfields force a misaligned access.
	Remove WARNED and fix long lines.  Assert that the processed OP0
	has an integral mode.
	(store_split_bit_field): Update the call to store_fixed_bit_field.
