[cfe-dev] Multiple root nodes for CallGraph?

[Arjun Singri]

Hi,

Thank you for replying. I will keep that in mind when writing the checker.

To use the CallGraph class I need to supply it an object of type "Program".
The only way I can get a Program object is through the Indexer object which
itself is obtained from AnalysisManager. But when the AnalysisManager object
is constructed in Frontend/AnalysisConsumer.cpp:148, a value of zero is
passed for the Indexer making the Indexer NULL. Why is this? Can I get a
reference to the Program object any other way?

Thanks,
Arjun
