Hi,
Does this prevent the diagnostic information from being generated (e.g.,
preprocessed source, etc.)?
See the tail end of main() in driver.cpp:
if (C.get())
Res = TheDriver.ExecuteCompilation(*C, FailingCommand);
// If result status is < 0, then the driver command signalled an error.
// In this case, generate additional diagnostic information if possible.
if (Res < 0)
TheDriver.generateCompilationDiagnostics(*C, FailingCommand);
