rSTAGING9c81006b6c1c: Specialized double-SHA256 with 64 byte inputs with SSE4.1 and AVX2
rABC9c81006b6c1c: Specialized double-SHA256 with 64 byte inputs with SSE4.1 and AVX2
Summary
  • Benchmark Merkle root computation
  • Refactor SHA256 code
  • Specialized double sha256 for 64 byte inputs
  • Use SHA256D64 in Merkle root computation
  • 4-way SSE4.1 implementation for double SHA256 on 64-byte inputs
  • 8-way AVX2 implementation for double SHA256 on 64-byte inputs
  • [MOVEONLY] Move unused Merkle branch code to tests
  • Enable double-SHA256-for-64-byte code on 32-bit x86
  • For AVX2 code, also check for AVX, XSAVE, and OS support

This is a backport of Core PR13191, PR13393 and PR13471

Depends on D1844 and D1845
