FFTW 3.3.8:

  • Fixed AVX, AVX2 for gcc-8.

By default, FFTW 3.3.7 was broken with gcc-8. AVX and AVX2 code assumed that the compiler honors the distinction between +0 and -0, but gcc-8 -ffast-math does not. The default CFLAGS included -ffast-math. This release ensures that FFTW works with gcc-8 -ffast-math, and removes -ffast-math from the default CFLAGS for good measure.
