Downgrading clang 15 to clang12

Hi! I'm fairly new to Arch Linux and i've been trying to downgrade my clang15 to clang 12.0.1 so I can use Valgrind, it appears to have some conflicts with the latest version, so I went and downgrade it to 12.0.1 version but then i got the following error

clang: error while loading shared libraries: libLLVM-11.so: cannot open shared object file: No such file or directory

I think I will need to recompile the libLLVM but I don't even know where to download the stuff and the step by step, do I actually need to do this? If I do can anyone help me out?

Don't do that. Try to solve the actual problem instead of trying a completely wrong workaround.

There are several AUR package for old clang versions, e.g. 10 or 13, but not 12. It may be easier to adapt one of those than to start from scratch.

If that is even the issue, there's no information on the actual problem, classic XY case

llvm11 & llvm13 are even in extra because some applications still need them.

@fabin : please describe the actual problem you have.
