[cfe-dev] traverse CFG in Clang

[Shuai Wang]

could anybody tell me how to traverse CFG in Clang towards c/cpp source
code?

Currently I am able to find out all the assignment declaration , do a
source to source transformation to insert certain code I want.

I want to find out all the basic control block, using source 2 source
transformation to insert certain code.

I think class clang::CFG could help but actually I have no idea how to use
it...

What I am referring now are these
tutorials<https://github.com/loarabia/Clang-tutorial>

Thanks !

Shuai
