Not sure if I understood correctly, what is the role of Git in this scenario?
For my use cases I just copy a number of precompiled versions of LLVM and put them under /opt/llvm/. Here is how it looks like on my machine:
> ls /opt/llvm/
3.8.0 3.9.0 4.0.0 5.0.0 6.0.0 7.0.0 8.0.0 monorepo
Then ,when I need to use a different version to compile something I usually override compiler using environment variables, e.g.:
> export CC=/opt/llvm/3.9.0/bin/clang
> export CXX=/opt/llvm/3.9.0/bin/clang++
> cmake or whatever else is needed
I hope it helps.
