#define HGCD2_METHOD 2 /* 3.2% faster than method 1 */ That'd be good! I did one variant with table lookup and an approximative quotient, which implies that one needed conditional swaps depending on a < b. That didn't beat plain division in my testing. But I also expect that we can beat plain division on more machines. My suggested code was not 6 times faster! I was fooled by inlining. It is 2-3 times faster only (on the system shell). -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org https://gmplib.org/mailman/listinfo/gmp-devel
