By the way, I know that this is not a bugzilla's mirror, but it seems you did something wrong wile bumping. For now it refuses to build on Broadwell telling > fftw-3.3.5/simd-support/simd-avx2.h:43:2: error: #error "compiling simd- avx2.h without avx2 support"
Although avx2 do exist in cpuinfo (and in cpuflags_x86 too, although there is no such flag for fftw itself).
