Research direction
Start by reading issue #51 and the existing SHA-512 implementation, then consult the linked Intel SHA Extensions and Intrinsics Guide references. Identify the SHA-512 entry points and determine how the new extensions should be selected; done means SHA-512 uses them on supported Intel hardware while existing behavior remains available elsewhere.
