x86_64: Add avx2 optimized __memcmpeq in memcmpeq-avx2.S No bug. This commit adds new optimized __memcmpeq implementation for avx2. The primary optimizations are: 1) skipping the logic to find the difference of the first mismatched byte. 2) not updating src/dst addresses as the non-equals logic does not need to be reused by different areas. 2021-09-30 20:37:09 +00:00			`#ifndef MEMCMPEQ`

x86_64: Add support for __memcmpeq using sse2, avx2, and evex No bug. This commit adds support for __memcmpeq to be implemented seperately from memcmp. Support is added for versions optimized with sse2, avx2, and evex. 2021-10-27 00:43:18 +00:00			`#endif`
