Igor Zamyatin <izamyatin at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |izamyatin at gmail dot com --- 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
