================
Comment at: llvm/lib/Transforms/Instrumentation/MemorySanitizer.cpp:3573
+      case LibFunc_atomic_load:
+        if (!isa<CallInst>(CB)) {
+          llvm::errs() << "MSAN -- cannot instrument invoke of libatomic load."
----------------
Probably need the same check for atomic_store.
