1 This is a test case for the identical-block combining algorithm, which runs after the SSA optimizer to recombine identical blocks (usually exception handlers) created during edge-splitting. 2 3 This test compares emitted code against a known-good (via eyeballing) 4 version, so it is possible for this test to spuriously fail if other 5 aspects of conversion end up altering the output in innocuous ways. 6
