            Bug ID: 17692
           Summary: debug.DumpCallGraph does not show extern function
                    calls
           Product: tools
           Version: trunk
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: analyze
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

I'm trying to generate a static callgraph for a mid-sized C++ project.
Compile with -analyze -analyzer-checker=debug.DumpCallGraph

The dumps don't show any calls to extern functions defined outside same source
file.  This makes the dump nearly useless.
