[PATCH 07/12] @extenddf2_{fprs,vsx}

[Segher Boessenkool]

2019-07-01  Segher Boessenkool  <seg...@kernel.crashing.org>

        * config/rs6000/rs6000.md (extenddf<mode>2_fprs): Make this a
        parameterized name.
        (extenddf<mode>2_vsx): Make this a parameterized name.
        (extenddf<mode>2): Use those names.  Simplify.
