   1 /* This file tests that we can successfully call each compiler-rt function. It is
   2    designed to check that the runtime libraries are available for linking and
   3    that they contain the expected contents. It is not designed to test the
   4    correctness of the individual functions in compiler-rt.
   5
   6    This test is assumed to be run on a 10.6 machine. The two environment
   7    variables below should be set to 10.4 and 10.5 machines which can be directly
   8    ssh/rsync'd to in order to actually test the executables can run on the
   9    desired targets.
