[cfe-dev] Multiple root nodes for CallGraph?

[Anna Zaks]

Hi Arjun,

scan-build is a script that hijacks the build system to call the static analyzer. Currently, the analyzer can only reason about one translation unit at a time.

So there is no reason to have multiple roots to represent different main functions. In addition, your checker would/should only be applicable to functions with internal linkage.

Cheers,
Anna.

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?
