--- Comment #13 from Paul Floyd <pjfl...@wanadoo.fr> ---
I also need to look more at #339596 (which has XOP and FMA4 but FMA4 already
got added in #369000).
As Mark has commented, finding suitable hardware is difficult. I just looked at
a AMD EPYC 7773X box ant it no longer has xop.
Here is a patch for the feature test for any eventual regression test
