I decided to try the FFT without addsub_n and it seems to actually go consistently about 3% faster, which is totally mysterious. So I have removed it from the two files it is defined in:
ifft_mfa_truncate_sqrt2.c ifft_truncate_sqrt2.c As sumdiff_n seems to be defined for all platforms as far back as the MPIR 2.1 series (even if it is not explicitly exported), I can just extern this in my flint code (and of course it won't be a problem in mpir). So the fft should build on all systems now. Bill. -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
