--- Comment #8 from Alexander Nesterovskiy <alexander.nesterovskiy at intel dot com> --- I'd say that it's not just fixed but improved with an impressive gain. It is about +4% on HSW AVX2 and about +8% on SKX AVX512 after r257734 (compared to r257732) for a 465.tonto SPEC rate. Comparing to reference r253973 it is about +2% on HSW AVX2 and +18% on SKX AVX512 (AVX512 was greatly improved in last 3 months).
