[cfe-dev] Multiple root nodes for CallGraph?

[Arjun Singri]

Hi,

I am currently trying to implement a checker that detects unused methods. I
am making use of the CallGraph class for this. Every time CallGraph detects
the "main" function, it designates it as the root node. Considering that
scan-build accepts multiple files each having a main function, does it make
sense to modify CallGraph to have mutlple root nodes?

Thanks,
Arjun
