Sorry for the inconvenience, it was my intention.

I had a patch for Clang ready yesterday, before pushing the LLVM one, but when I wanted to push in clang, I had to rebase and the code was not compiling anymore I had a compile failure in Clang. And by the time I got my llvm and clang in sync again, and by the time to run the test suite, you got the exact same patch in.

Best,
