1 // Test that the driver correctly combines its own diagnostics with CC1's in the
2 // serialized diagnostics. To test this, we need to trigger diagnostics from
3 // both processes, so we compile code that has a warning (with an associated
4 // note) and then force the driver to crash. We compile stdin so that the crash
5 // doesn't litter the user's system with preprocessed output.
