[llvm-dev] How to count instructions in a function? (original) (raw)

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 -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20171129/35239a01/attachment.html>
