It's on the Phab issue, but for some reason Phab isn't sending out emails.
You can view it there, but I'll go ahead and attach it here anyway.

* and utilities.
*
* LLVM uses a polymorphic type hierarchy which C cannot represent, therefore
* parameters must be passed as base types. Despite the declared types, most
* of the functions provided operate only on branches of the type hierarchy.
* The declared parameter names are descriptive and specify which type is
* required. Additionally, each type hierarchy is documented along with the
* functions that operate upon it. For more detail, refer to LLVM's C++ code.
* If in doubt, refer to Core.cpp, which performs parameter downcasts in the
* form unwrap<RequiredType>(Param).
*
* Many exotic languages can interoperate with C code but have a harder time
* with C++ due to name mangling. So in addition to C, this interface enables
* tools written in such languages.
