flang/test/Driver/missing-input.f90

   1 ! Test the behaviour of the driver when input is missing or is invalid. Note
   2 ! that with the compiler driver (flang), the input _has_ to be specified.
   3 ! Indeed, the driver decides what "job/command" to create based on the input
   4 ! file's extension. No input file means that it doesn't know what to do
   5 ! (compile?  preprocess? link?). The frontend driver (flang -fc1) simply
   6 ! assumes that "no explicit input == read from stdin"
