--- Comment #13 from Richard Henderson <rth at gcc dot gnu.org> ---
I can clean up the rs6000 some more to avoid some objections
that Segher raised -- by-hand rtl generation etc.
Or, I've just about finished testing the simplify-rtx-only
patch suggested in
https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01858.html
So, that at least is a working option to fix the x86 regression
without touching the rs6000 backend during stage4.
