Noah Goldstein	f53790272c	x86: Optimize less_vec evex and avx512 memset-vec-unaligned-erms.S ... No bug. This commit adds optimized cased for less_vec memset case that uses the avx512vl/avx512bw mask store avoiding the excessive branches. test-memset and test-wmemset are passing.

H.J. Lu	1b968b6b9b	x86-64: Add memset family functions with 256-bit EVEX ... Update ifunc-memset.h/ifunc-wmemset.h to select the function optimized with 256-bit EVEX instructions using YMM16-YMM31 registers to avoid RTM abort with usable AVX512VL and AVX512BW since VZEROUPPER isn't needed at function exit.	2021-03-29 07:40:17 -07:00
