generating CFG for whole source code with LLVM

Question

Does anyone from LLVM community know if there is a way to generate CFG for the whole input source code using opt -dot-cfg foo.ll(.bc) ? as this one generates the CFG per function thus the connections between functions will be ignored.

It seems that the older analyze tool has depreciated.

That's ICFG, but llvm doesn't have accurate callgraph to do that. – Yoong

Answer 1

I wonder if you found any way to get interprocedural CFG. I found that inlining call functions by other inliner passes might be helpful but I couldn't be able to get it to work yet. I've posted this Finding all possible paths in a c/c++ program by LLVM
