[llvm-dev] How to get return address at llvm ir level?

[Bekket McClane via llvm-dev]

Correct...you can always call that intrinsic explicitly. However, I don't
think it would help the original question, since the question is how to get
the return address inside a LLVM Pass, instead of getting the return
address after executing the program with Intrinsic::returnaddress inside.
Also, executing a program containing Intrinsic::returnaddress won't get you
anything - even failed to pass the linking stage - without special support,
since the intrinsic is just a function declaration.

Bests,
Bekket
