            Bug ID: 22095
           Summary: IntelJITEvents has bitrotted through DebugInfo changes
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Generic Execution Engine Support
          Assignee: dexonsmith at apple.com
          Reporter: kfischer at college.harvard.edu
                CC: lhames at gmail.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

On current trunk IntelJITEvents doesn't build anymore due to
AssertingVH<MDNode> in lib/ExecutionEngine/EventListenerCommon.h, but even
after fixing that, the tests still fail with

llvm-jitlistener:
/home/kfischer/julia-clang/deps/llvm-svn/lib/IR/DebugInfo.cpp:1453:
llvm::DIRef<T>::DIRef(const llvm::Metadata*) [with T = llvm::DIScope]:
Assertion `isScopeRef(V) && "DIScopeRef should be a MDString or MDNode"'
failed.

It seems like none of the build bots test this code at all, which should be
fixed if possible. Curiously, it also doesn't seem like the JitEvents tests are
even being run with `make check` since I didn't see the above crash (I had to
run the test manually).
