If `Verifier` has already found a failure, don't call `DebugInfoVerifier`. The latter sometimes crashes in `DebugInfoFinder` when the former would give a nice message. The only two cases I found it crashing are explicit verifier tests I've added: - test/Verifier/llvm.dbg.declare-expression.ll - test/Verifier/llvm.dbg.value-expression.ll However, I assume frontends with bugs will create invalid IR as well. IMO, the `DebugInfoVerifier` should never crash (instead, it should fail to verify), but subtleties like that will be easier to work out once it's enabled again. This is part of PR22777. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232418 91177308-0d34-0410-b5e6-96231b3b80d8
