Because it requires gcc 8 which doesn't support znver2. It should do something similar to downgrade_arch_flags from toolchain.eclass. Probably that function should be moved to some other eclass to be used from non-gcc ebuild like this one?

I have the same problem with a ryzen 3900X processor. I suppose I can force CFLAGS to znver1 instead of znver2 for this package to solve it. I did not try yet.
Patches welcome.
Created attachment 690876 [details] ebuild for nvidia-cuda-sdk-11.1.1
I finally preferred to use cuda 11 that use gcc 9.3 that support znver2. So I modified ebuild for version 11.1.1, see attached file. Need some more testing. I had some compilation core dump, but when continuing compilation did not reproduce (with ebuild nvidia-cuda-sdk***.ebuild compile). So I suppose it is a race condition problem, but did not investigate for now. I also tried with cuda 11.2.0, but had many segmentation faults with cicc. Not systematically reproducible. I could compile it by repeating maybe 20 times "ebuild nvidia-cuda-sdk***.ebuild compile". Maybe something to do with this bug https://bugs.gentoo.org/show_bug.cgi?id=762050 Hope this helps.
I tested MAKEOPTS="-j1" emerge --ask nvidia-cuda-sdk and indeed nvidia-cuda-sdk-11.1.1 compiles fine. So core dump pb I had seem to be a problem of compilation of sdk on multiple cores.
ci has reproduced this issue with version 11.5.1 - Updating summary.
