[z0z0z]

LLVM has support for -march=znver2 target, but in RPCS3 is compiling modules for znver1 on third-gen Ryzen.

RPCS3 8e39c778a15b6315f395f8aa2f1203a64a8d2efb (latest commit as of now) on x86_64 Linux, Ryzen 3600. Compiled against bundled LLVM.

S LDR: Boot successful.

Yeah, I've been seeing this too. I tend to set "Use LLVM CPU:" to znver2 manually in the config file.

Can someone test the PR?

[Silanda]

Looks good here!

This should now be fixed in upstream LLVM: https://github.com/llvm/llvm-project/commit/ff75bf6ac93a9ef5a7d41f7645e02fde3e968ce1
