Consider the redc fn in the file mpz/powm.c , this is just a mpn_mul_basecase with a "twist" , so we would expect much the same speed improvement that we get from going from a c to asm version of mul_basecase , and gmpbench uses rsa which uses mpz_powm. I expect gmp-4.3 has a K8 asm mpn_redc_basecase. > > But there is nothing stopping us putting it into eMPIRe. > > > :) > : > > We can test against the FLINT FFT to make sure it gives correct > > results.
