11834 * expr.c (expand_assignment): Fix up a typo in simplify_gen_subreg
11835 last argument when extracting from CONCAT. If either from_real or
11836 from_imag is NULL, use expansion through memory. If result is not
11837 a CONCAT and simplify_gen_subreg fails, try to simplify_gen_subreg
11838 the parts directly to inner mode, if even that fails, use expansion
11839 through memory.

11842 * expmed.c (expand_shift_1): For 2-byte rotates by BITS_PER_UNIT,
11843 check for bswap in mode rather than HImode and use that in expand_unop
11844 too.
