[Bug-cflow] cflow support for logical flow, not just function call flow

[Davin Gibb]

Hi everyone! I'm hoping someones experience can help with my question.
I'm after a flowchart generator from c source code. cflow, does
provide index'd function call flow, by utilising a stack like
structure (from what I can tell from a quick code dive). What I'm
after is an enhancement on that, which provides alternate depth first
searches from branching statements { if, else, while, break, continue
} and have a representation of that printed.

>From what I can tell, cflow would be a good tool to add this
functionality in, I can see that the scanner already picks up these c
branch ops as type WORD, so I figure what would need to happen is to
create some sort of tree structure to record this as we scan the
source code.

Thoughts? Does this already exist in freeware? Thanks in advance, Davin.
