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. 9 10!
