Why not set OpenCLVersion in lib/Frontend/CompilerInvocation.cpp instead? Then you wouldn't have to "override" the version in multiple places (which increases the risk of missing one or more places).

This also exposes the OpenCL 2.0 types in OpenCL C++ mode; it would be good to mention that in the commit message.

I think we deliberately wanted to separate OpenCL C versions from OpenCL C++. One big reason is that we don't automatically inherit the same behavior but rather do it explicitly. I could look at moving this logic into extensions implementation directly however this will mean it will need to know more internals of LangOpts. I will give it a try!

Even nicer to have it only inside the extension logic indeed.
