Hi JP, thanks. Did you notice that the make tuneup caused an error. Did you mean to do make speed?
It's not at all clear to me which is the better assembly source. We only care about the speed of the basecase up to the crossover with karatsuba, which seems to be very low, maybe 14 (assuming that make error didn't affect things). >From 1-13 limbs 10 of the 13 values are lower with Jason's code. So I think we should stick with it on the atom. But I'll wait for you to confirm that the make error didn't actually stop speed being rebuilt. Bill.
