Hi all, I was able to create a pass following [1]. Now goal is amend the pass and try to dump the call graph. I think I have properly amended the source extending my pass from CallGraphSCCPass but unfortunately every time I run it, it crashes. I tried with llvm-6 and llvm-7. I notice that if I change EP_EarlyAsPossible to anything else it does not crash but I don't see the expected string

Hello all, I've followed the example in https://github.com/CompilerTeaching/SimplePass/blob/master/SimplePass.cc in order to create a custom pass. The pass needs to be added before any transformation, so I used EP_EarlyAsPossible extension point to register it. Furthermore, I need to access to every GlobalVariable in the IR, so my pass has to be a ModulePass, like this: struct MyPass :

> >> + EP_EnabledOnOptLevel0 > > I'd rename this as EP_AlwaysEnabled > Renamed, see the attachment. But note that one needs to add his pass at two extension points: at O0 and wherever else he wanted to add it. Won't such a name confuse the user? E.g. he may think that just adding a pass as "EP_AlwaysEnab...
