#include "textflag.h"
// SHA-1 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.
