[bug-cflow] a detailed control flow graph

[Dazhi Zhang]

Hi, 
I tried the cflow and it is cool. What I need now is a tool that can construct control flow graph for C as follows:
it identify basic blocks of C source code, the CFG is nodes and edges, that the nodes represent the basic blocks and edges represent the control flow(such as if, for etc), not only the function calls, but all statements. Can cflow achieve this? Or some other tools can achieve it?

Thank you very much!
