llvm dev - Jul 2009 - [LLVMdev] how to get Callgraph from a bunch of .bc files?

Dear All,

The problem I have is to how to get the callgraph for the whole application
given .bc file of each source file? using opt as "opt -dot-callgraph
main.bc" gives a single callGraph for main.bc but how can I generate a
CallGraph that includes all functions in all the .bc files?

Thanks,
::Saman

link the .bc files together into one mega .bc file using llvm-link.
