Instead of doing it per Function, it may have to be done for the entire Module by instantiating MachineFunction objects for every Function inside the Module. This might require major changes to the PassManager framework as well.

Hi all, I am trying to build a global control flow graph at machine code level. Essentially, I need the handles to the MachineFunction's corresponding to every call site inside a MachineFunction in order to get the handles to MachineBasicBlock's with return statements inside the callee. Currently, the codegen module processes one MachineFunction at a time and hence I can't find a way
