--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> --- If I'm correct it's also problematic on Haswell with -march=native. Particularly the only affected file is power.fppized.o. I also tried -mno-fma4 and -mno-fma and it does not help. From the assembly diff, there is additional vectorization happening.
