These tests invoke do_lower_jumps() in isolation (using the glsl_test executable) and verify that it transforms the IR in the expected way. The unit tests may be run from the top level directory using "make check". For reference, I've also checked in the Python script create_test_cases.py, which was used to generate these tests. It is not necessary to run this script in order to run the tests. Acked-by: Chad Versace <chad@chad-versace.us>
