--- Comment #2 from vincenzo Innocente <vincenzo.innocente at cern dot ch> ---
is there any mechanism to tell gcc to generate the AVX2 clone using fma?
I understand it reduces portability still at the moment I have to support
mostly
Intel platforms.
for AMD, gcc suggests to use avx128 so it would anyhow requires a different
library to exploit fma4.
