x86-64: Add AVX optimized string/memory functions for RTM Since VZEROUPPER triggers RTM abort while VZEROALL won't, select AVX optimized string/memory functions with xtest jz 1f vzeroall ret 1: vzeroupper ret at function exit on processors with usable RTM, but without 256-bit EVEX instructions to avoid VZEROUPPER inside a transactionally executing RTM region. 2021-03-05 15:26:42 +00:00			`#define USE_AS_STRNCMP 1`
