For tuned *_METHOD values, it might be useful to let tuneup also add a comment with next best method and margin, something like #define HGCD2_METHOD 2 /* 3.2% faster than method 1 */ > Did you have a chance of playing with some code which takes care of > small quotients without branches or division? 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. Regards, /Niels -- Niels Möller. PGP-encrypted email is preferred. Keyid 368C6677.
