/* This file tests that we can successfully call each compiler-rt function. It is
designed to check that the runtime libraries are available for linking and
that they contain the expected contents. It is not designed to test the
correctness of the individual functions in compiler-rt.
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
desired targets.
