test/MC/ARM/ltorg-darwin.s

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