[llvm-dev] How to debug passes

[Lorenzo Casalino via llvm-dev]

> opt -load lib­dum­my­pass.so -dum­my­pass hel­lo.ll

Looks like you are loading a shared library different from "LLVMHello.so".

did you change the name of the compilation unit from "Hello.cpp" into
"dummypass.cpp"?


(As asked previously by Andrzej) did you register the dummy pass?

> RegisterPass<DummyPass> X("dummypass", "whatever");


Is any error/warning triggered when loading the library, executing "opt" or
during compilation?


Could you attach the fragment containing the "DummyPass"?
