2018-07-09Merge #13386: SHA256 implementations based on Intel SHA ExtensionsWladimir J. van der Laan
66b2cf1ccfad545a8ec3f2a854e23f647322bf30 Use immintrin.h everywhere for intrinsics (Pieter Wuille) 4c935e2eee456ff66cdfb908b0edffdd1e8a6c04 Add SHA256 implementation using using Intel SHA intrinsics (Pieter Wuille) 268400d3188200c9e3dcd3482c4853354388a721 [Refactor] CPU feature detection logic for SHA256 (Pieter Wuille) Pull request description: Based on #13191. 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. Benchmarks for 9001-element Merkle tree root computation on an AMD Ryzen 1800X system: * Using generic C++ code (pre-#10821): 6.1ms * Using SSE4 (master, #10821): 4.6ms * Using 4-way SSE4 specialized for 64-byte inputs (#13191): 2.8ms * Using 8-way AVX2 specialized for 64-byte inputs (#13191): 2.1ms * Using 2-way SHA-NI specialized for 64-byte inputs (this PR): 0.56ms Benchmarks for 32-byte SHA256 on the same system: * Using SSE4 (master, #10821): 190ns * Using SHA-NI (this PR): 53ns Benchmarks for 1000000-byte SHA256 on the same system: * Using SSE4 (master, #10821): 2.5ms * Using SHA-NI (this PR): 0.51ms Tree-SHA512: 2b319e33b22579f815d91f9daf7994a5e1e799c4f73c13e15070dd54ba71f3f6438ccf77ae9cbd1ce76f972d9cbeb5f0edfea3d86f101bbc1055db70e42743b7

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.

2016-04-15crypto: bytes counts are 64 bitWladimir J. van der Laan
Byte counts for SHA256, SHA512, SHA1 and RIPEMD160 must be 64 bits. `size_t` has a different size per platform, causing divergent results when hashing more than 4GB of data.
