| @ This test has a partner (ltorg.s) that contains matching |
| @ tests for the .ltorg on linux targets. We need separate files |
| @ because the syntax for switching sections and temporary labels differs |
| @ between darwin and linux. Any tests added here should have a matching |
| @ test added there. |
