        * config/rs6000/vsx.md (p9_xxbrq_v16qi): Change input operand
        constraint from =wa to wa.  Avoid a subreg on the output operand,
        instead use a pseudo and subreg it in a move.
        (p9_xxbrd_<mode>): Changed to ...
        (p9_xxbrd_v2di): ... this insn, without VSX_D iterator.
        (p9_xxbrd_v2df): New expander.
        (p9_xxbrw_<mode>): Changed to ...
        (p9_xxbrw_v4si): ... this insn, without VSX_W iterator.
        (p9_xxbrw_v4sf): New expander.
