[cfe-dev] OpenCL parsing / type support

[Arnaud Allard de Grandmaison]

Thanks John. I have seen you had time to improve the patch as well.

This is also what I assume, as I update llvm and clang at the same time, but for historical reasons, I am working with a git clone for llvm, and an svn repository for clang. Yes, this is _ugly_. And this can create such discrepancies from time to time. Just dreaming of the day when it will be possible to directly clone llvm and clang form an official llvm.org git repository... This would definitely help me to maintain my company branch and help as well the patch flow.

Seems reasonable to me;  I'll go ahead and commit this when I get a chance.

DIFile was added to LLVM on Monday in r97994.  In general Clang/head is tightly coupled to LLVM/head, and you should assume that missing declarations (particularly in the llvm:: namespace) are due to such changes.
