That's an input file for an obscure "loop mixer" tool, IIRC, it was written mainly by David Harvey for use with GMP loops. This tool tries permuting the instructions of an assembly loop, taking dependencies into account, benchmarks each variant, and tries to find the fastest instruction sequence. It seems I tried this toool on x86 sha1_compress back in 2009, on an AMD K7, and it gave a 17% speedup at the time, according to commit message for 1e757582ac7f8465b213d9761e17c33bd21ca686. So you can just ignore this file. And you may want to look at the more readable version of x86/sha1_compress.asm, just before that commit. Regards, /Niels -- Niels Möller.
