| ; Test to ensure -backend-options work when invoking the ThinLTO backend path. |
| |
| ; This test uses a non-existent backend option to test that backend options are |
| ; being parsed. While it's more important that the existing options are parsed |
| ; than that this error is produced, this provides a reliable way to test this |
| ; scenario independent of any particular backend options that may exist now or |
| ; in the future. |
