Hi all,
  If you are checking out LLVM's source, it's important to read this message:
https://lists.llvm.org/pipermail/llvm-dev/2018-October/127055.html

Although I have not contributed all that much to LLVM, I think this will make life a little easier. Note that the full transition is still ongoing. LLVM's SVN is still the "real" truth.

Cheers,
  Johan
