// SHA1 block routine. See sha1block.go for Go equivalent.
//
// There are 80 rounds of 4 types:
// - rounds 0-15 are type 1 and load data (ROUND1 macro).
// - rounds 16-19 are type 1 and do not load data (ROUND1x macro).
// - rounds 20-39 are type 2 and do not load data (ROUND2 macro).
// - rounds 40-59 are type 3 and do not load data (ROUND3 macro).
// - rounds 60-79 are type 4 and do not load data (ROUND4 macro).
//
// Each round loads or shuffles the data, then computes a per-round
// function of b, c, d, and then mixes the result into and rotates the
// five registers a, b, c, d, e holding the intermediate results.
//
// The register rotation is implemented by rotating the arguments to
// the round macros instead of by explicit move instructions.
// Like sha1block_amd64.s, but we keep the data and limit pointers on the stack.
// To free up the word pointer (R10 on amd64, DI here), we add it to e during
// LOAD/SHUFFLE instead of during MIX.
//
// The stack holds the intermediate word array - 16 uint32s - at 0(SP) up to 64(SP).
// The saved a, b, c, d, e (R11 through R15 on amd64) are at 64(SP) up to 84(SP).
// The saved limit pointer (DI on amd64) is at 84(SP).
// The saved data pointer (SI on amd64) is at 88(SP).

crypto/sha1: Optimise FUNC1 with alternate formulation According to Wikipedia: http://en.wikipedia.org/wiki/SHA-1 there is an alternate formulation for the FUNC1 transform, namely f1 = d xor (b and (c xor d)) instead of f1 = (b and c) or ((not b) and d) This reduces the instruction count of FUNC1 from 6 to 4 and makes about 5% speed improvement on amd64 and suprisingly 17% on 386. amd64 Intel(R) Core(TM) i7 CPU Q 820 @ 1.73GHz: benchmark old ns/op new ns/op delta BenchmarkHash8Bytes 506 499 -1.38% BenchmarkHash1K 3099 2961 -4.45% BenchmarkHash8K 22292 21243 -4.71% benchmark old MB/s new MB/s speedup BenchmarkHash8Bytes 15.80 16.00 1.01x BenchmarkHash1K 330.40 345.82 1.05x BenchmarkHash8K 367.48 385.63 1.05x i386 Intel(R) Core(TM) i7 CPU Q 820 @ 1.73GHz: benchmark old ns/op new ns/op delta BenchmarkHash8Bytes 647 615 -4.95% BenchmarkHash1K 3673 3161 -13.94% BenchmarkHash8K 26141 22374 -14.41% benchmark old MB/s new MB/s speedup BenchmarkHash8Bytes 12.35 13.01 1.05x BenchmarkHash1K 278.74 323.94 1.16x BenchmarkHash8K 313.37 366.13 1.17x The improvements on an Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz were almost identical.
