[cfe-dev] Way to compare two Function bodies.

[Pavan Pattanada]

By "same", I mean, their ASTs to be the same to start with. I am working on
a tool,  which is used to syntactic/semantic similarity between two
versions of the code base. So far, I have been able to get the
FunctionDecls of both versions of a function into memory. But I am not sure
how to compare them.
