--- Comment #1 from Julia Koval <julia.koval at intel dot com> ---
I suspect the problem is in >gcc/config/i386/driver-i386.c:
>if (has_wbnoinvd)
>cpu = "icelake-server";
I would change to has_wbnoinvd && has_gfni to try. Sorry, I don't have a Ryzen
right now to try, I will check and send fix ASAP.
