Comment (by bdubbs):
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.
