7050 * expr.c (store_expr_with_bounds): Use simplify_gen_subreg instead of
7051 convert_modes if target mode has the right side, but different mode
7052 class.
7054 PR middle-end/83609
7055 * expr.c (expand_assignment): Fix up a typo in simplify_gen_subreg
7056 last argument when extracting from CONCAT. If either from_real or
7057 from_imag is NULL, use expansion through memory. If result is not
7058 a CONCAT and simplify_gen_subreg fails, try to simplify_gen_subreg
7059 the parts directly to inner mode, if even that fails, use expansion
7060 through memory.
7062 PR middle-end/83623
7063 * expmed.c (expand_shift_1): For 2-byte rotates by BITS_PER_UNIT,
7064 check for bswap in mode rather than HImode and use that in expand_unop
7065 too.
