--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I don't think we should fix anything in GCC here - the family names are rea=
lly
aliases and while we now have skylake-avx512 nobody thought of haswell-avx2
(or haswell-noavx2).  I really blame Intel here for very bad product
segmentation here ...

Can you please provide the exact CPU model here, maybe cut&pasting from
/proc/cpuinfo?=
