Subject: Re: [mpir-devel] MPIR 2.6.0-alpha2 released

Unfortunately, GMP-ECM will have to be rewritten to use the new FFT.

Fortunately, the best_k and next_size stuff is no longer needed. So
this shouldn't be too much work.

=========================
Doesn't this break the GMP compatibility mode?

Can the old calls be mapped to the new FFT interface - that is dummy calls for not needed items and a mapping from the old FFT call to the new one?

This might be inefficient but it would be better than nothing until something better can be arranged.

In any event, we surely need to offer advice on what to do to use the new FFT in place of the old one - maybe we already do this in the 2.6.0 manual?

I would certainly like to offer the GMP-ECM team a set of changes they need to make to use the new version of MPIR and gain access to the much faster FFT that you have produced.
