llvm/test/Transforms/Coroutines/coro-debug-dbg.addr-swift.ll

; Tests whether we properly setup llvm.dbg.addr for Swift.
;
; Since we do not have any guarantees around the usage of llvm.dbg.addr, we can
; not propagate them like we do llvm.dbg.declare into funclets. But if users
; create the debug_value for us, make sure that we propagate llvm.dbg.addr into
; the beginning coroutine and all other funclets.
