This adds SHA256 implementations that use Intel's SHA Extension instructions (using intrinsics). This needs GCC 4.9 or Clang 3.4. In addition to #13191, two extra implementations are provided: * (a) A variable-length SHA256 implementation using SHA extensions. * (b) A 2-way 64-byte input double-SHA256 implementation using SHA extensions.

* Merge #13393: Enable double-SHA256-for-64-byte code on 32-bit x86Wladimir J. van der Laan2018-06-121-2/+4
|\ | | | | | | | | | | | | | | | | | | | | | | 57ba401abcfe564a2c4d259e0f758401ed74616d Enable double-SHA256-for-64-byte code on 32-bit x86 (Pieter Wuille) Pull request description: The SSE4 and AVX2 double-SHA256-for-64-byte input code from #13191 compiles fine on 32-bit x86 systems, but the autodetection logic in sha256.cpp doesn't enable it. Fix this. Note that these instruction sets are only available on CPUs that support 64-bit mode as well, so it is only beneficial in the (perhaps unlikely) scenario where a 64-bit CPU is running a 32-bit Bitcoin Core binary.
