I read unidiffs really poorly, in particular for asm code. But to me,
it seems like you undo the software pipelining of the current MIPS code,
replacing it with plain ("naive") asm code. I am not sure that is a
On which MIPS CPUs did you test and benchmark the code? Did you not see
Granted, the MIPS asm code in GMP is largely obsolete as it was
optimised for defunct MIPS CPUs. But having said that, I would like to
avoid performance regressions for new as well as old implementations.
And removing software pipelining almost always hurt performance.
