These improvements are now (finally!) in GMP repo. I have not run any timing tests, as I trust you to worry about the performance.
A mistake we GMP develiopers have made in the past is couting cycles for inner loops for quite large trip counts, and then accidentally adding overhead as a side effect of beating down the cycle count. One should never forget that most bignum computations probably use moderately large numbers, which means decreasing overhead. Running commands like tune/speed -p10000000 -C -s1-100 mpn_mul_basecase tune/speed -p10000000 -C -s1-100 mpn_addmul_1.0xcafecafecafecafe are helpful. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org https://gmplib.org/mailman/listinfo/gmp-devel
