[cfe-dev] Getting started with source code analysis using CLang

[Martin C. Martin]

Hi Stefan,

The Parser class is probably what you want, it produces an AST.  You can 
look at the existing Frontend to see how its constructed & called.  You 
can also start clang with a trivial C program and set breakpoints to 
find out what code paths are actually taken.

As far as I can tell, there isn't a lot of documentation outside of the 
code itself.  But the code is very well written, so it should be easy to 
figure it out.

Best,
Martin
