How are `__attribute__`s parsed in Clang?

I’m thinking about making a patch to add support for the printf attribute’s sibling, wprintf, but I tried searching the codebase, and couldn’t find it, and there’s literally thousands of files.

I filed bug report 37288 on it and nobody responded, so I think I’ll just see if I can add support for it myself.
