C and C++ control flow graph generator and analyzer
CoFlo generates Control-Flow Graphs from C and C++ source code. It can then output the graphs in a number of ways and perform various control flow analyses.
NOTE: CoFlo has not been under active development for several years. At this time, I suggest you look into LLVM-based tooling to see if there is anything similar to CoFlo which will meet your needs.
XRay is an analysis tool built upon your SCMs, aimed to consolidade project statistics from many repositories in a single tool, generating code reports and development statistics obtained from log data and file versions.
