      Description

      We would like to contribute the SHA256 AVX2 intrinsic.

      This instrinsic is for x86 AVX2 architecture with no supports_sha() available. It is LP64 code only.

      The patch delivers x2 performance gain for the latency and throughput - both are measured on an average message.
