gcc code-flow information (URG).

[Shashidhara S Bapat <ssbapat@xxxxxxxxxxxxx>]

Hi All,
Is there any option in GCC to get the code-flow of the whole project (I 
have nearly 100 files (abt 50,000 lines of code))?. Please let me know 
if anyone knows about such an option/ OR any open-source tool to do so.
