Makes Bulldozer prefer AVX functions rather than AVX2, which are 64% slower: AVX: 117653 decicycles in av_tx (fft), 1048535 runs, 41 skips AVX2: 193385 decicycles in av_tx (fft), 1048561 runs, 15 skips The only difference between both is that vgatherdpd is used in the former. We don't want to mark them with the new SLOW_GATHER flag however, since gathers are still faster on Haswell/Zen 2/3 than plain loads. |
