--- Comment #13 from Igor Zamyatin <izamyatin at gmail dot com> ---
I also see performance degradation for several spec2006 tests after this commit
(mostly on FP tests).
Eg. on Haswell 433.milc shows ~-7-8% if compiled with "-O3 -flto -funroll-loops
-march=core-avx2"

Not investigated this so far though
