I actually looked at code generation (on x86-64) for the C fallback, and it should be quite doable to re-write the C one to generate good code on x86-64. On 32-bit x86, I suspect the register pressures are so intense that it's unrealistic to expect gcc to do a good job, but the Mozilla SHA1 C code really seems _designed_ to be slow in stupid ways (that whole "byte at a time into a word buffer with shifts" is a really really sucky way to handle the endianness issues). So if you'd like to look at the C version, that's definitely worth it. Much bigger bang for the buck than trying to schedule asm language and having to deal with different assemblers/linkers/whatnot.
