There is a VERY good performance gain on ppc-linux.

I just committed fftw-3.1 to portage CVS. Currently, it is masked for
further testing. It works fine for me and passes all the tests, but please
give it a spin an report back.

Thanks,
Markus

I can confirm that fftw 3.1 works OK on x86 (Intel Pentium-M) architecture. Here are the flags I used for compilation:

[ Found these USE variables for sci-libs/fftw-3.1 ]
 U I
 - - 3dnow   : Adds support for 3dnow multimedia processor instructions
 - - altivec : Adds support for optimizations for G4 and G5/ppc970 processors
 + + sse     : fast floating point optimization for PentiumIII+ class chips
 + + sse2    : faster floating point optimization for SSE2 capable chips

BR,

Hi  Adam,

Thank you very much for reporting back. After some further testing I'll 
hopefully be able to unmask fftw-3.1 soon.

Thanks,
Markus
