# This test was generated using SelectionDAG, where the compilation flow does
# not match the assumptions made in MachineUA. For now, this test mostly serves
# the purpose of catching in any crash when invoking MachineUA. The test should
# be deleted when it is clear that it is not actually testing anything useful.
