+@ This test has a partner (ltorg-darwin.s) that contains matching
+@ tests for the .ltorg on darwin 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.
