--- Comment #4 from Hongtao.liu <crazylht at gmail dot com> --- > Oops, > will backport r10-2664-ga9fcfec30f70c30883f53d4b1bd533fbea0e9fb2 (tigerlake > part) to gcc9. PTA_AVX512VP2INTERSECT is enabled in GCC10, don't plan to backport to gcc9, so in GCC9 -march=native wouldn't enable -mavx512vp2intersect, also kl and widekl.
