relating LLVM AA information back to C AST?

Hi guys,

I'd like to get alias-analysis information for some C code I have.
AFAIK, clang relegates all of its alias analysis to LLVM's alias
analysis implementations.

Does anyone know if there's a decent way to (in an automated manner)
relate LLVM's AA results back to variables/expressions appearing in
the original clang AST?

Thanks,
Christian
