Against their trunk. It doesn't work for me right now either. Sorry,
sometimes LLVM/Clang moves pretty fast and it's a pain to keep up.
Why not target releases?
We're using newish functionality in LLVM/Clang that has bugs. We want
to get fixes for them (some of which we submit ourselves).
I don't see a specific number in INSTALL, only a recommendation about
what to do if I wanted to target 3.0.
You have downloaded the 2.0.1 release? Its INSTALL file says you need
LLVM/Clang r158227. I just checked.
