1! Verify that the driver correctly processes `-fsyntax-only`.
2!
3! By default, the compiler driver (`flang`) will create actions/phases to
4! generate machine code (i.e. object files). The `-fsyntax-only` flag is a
5! "phase-control" flag that controls this behavior and makes the driver stop
6! once the semantic checks have been run. The frontend driver (`flang -fc1`)
7! runs `-fsyntax-only` by default (i.e. that's the default action), so the flag
8! can be skipped.
