| /* This file tests that we can successfully call each compiler-rt function. It is |

| |
| This test is assumed to be run on a 10.6 machine. The two environment |
| variables below should be set to 10.4 and 10.5 machines which can be directly |
| ssh/rsync'd to in order to actually test the executables can run on the |
