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