[cfe-dev] Need help with source-to-source translation

[Marcel Schaible via cfe-dev]

Manuel, thanks for your help. Of course I went already through a bunch 
of documentation including libtooling.
My tool is performing now the basic setup and can transform some simple 
cases.

Do you know by chance how to retrieve the ASTContext from a ReturnStmt 
and a FuncDecl?

BTW: Your presentation at the EURO LLVM was very helpful!

Greetings from Munich

Marcel
