--- Comment #5 from Hongtao.liu <crazylht at gmail dot com> --- Also i think masked epilog(--param=vect-partial-vector-usage=1) should be good for general cases under AVX512, espicially when main loop's vector width is 512, and the remain tripcount is not enough for 256-bit vectorization but ok for 128-bit vectorization.
