[cfe-dev] CFG documentation

[Ted Kremenek]

Hi Gaurav,

There is some documentation on the CFG here:

  http://clang.llvm.org/docs/InternalsManual.html#CFG

It's a bit dated, but it explains the core concepts of how the CFG is represented.  The CFG has recently been expanded so that it can contain other elements besides just Stmt*, but the design is still the same.

Note that you can dump CFGs from the command line:

$ clang -fsyntax-only -Xclang -analyze -Xclang -dump-cfg t.c
