Dear Zubin,
If I were you, I would write a ModulePass that uses the CallGraph analysis to get a call graph. I would then iterate over the nodes in the call graph and propagate information from callees to callers.

Hello,
I am trying to count IR instructions in a function for static analysis using llvm pass. In contrast with existing examples, I am trying to include instruction counts of all the callees of the function.
Counting the instructions of a function is easy using passes, but iterating through the module's CallGraph is proving to be confusing. I believe I have to use CallGraphWrapperPass to get both module pass and its CallGraph. How do I iterate through the CallGraph in runOnModule()? A simple print callee names example would be highly appreciated.
Thanks,Zubin
