AMD earlier this week quietly published a new version of its AOCC code compiler that is now rebased against the upstream LLVM/Clang 12.0 compiler state...

Great I missed the notification. Just recently I have tried to build the kernel with aocc instead of llvm but got an build error quite early in the build process. Llvm was fine. Maybe with this release it might work.

Ditto, only with KDE and the build error.

On my 3600XT with AOCC 3.1 I can build the xanmod 5.13.1rt kernel after sourcing the setupenv.sh in /opt/AMD...
with
$make LLVM=1 LLVM_IAS=1 menuconfig
setting arch to amd znver2
and only supported CPU vendor AMD.
Experimental build full lto
$make LLVM=1 LLVM_IAS=1 -j12 deb-pkg
(If you are on deb derivate)

Took longer than LLVM 12 with the same settings. No error boots correctly.

Are these changes by AMD being pushed back upstream to LLVM?

Yes they are.

for those interessted https://openbenchmarking.org/result/...IB-XANMOD51372
the kernel is slightly very slightly better build with aocc in pts/desktop-graphics compared to llvm12. might be within noise levels.
