-/**
- * @file mo-satcycle.cc
- * @brief MO satisfaction cycle test
- *
- * This program has a peculiar behavior which is technically legal under the
- * current C++ memory model but which is a result of a type of satisfaction
- * cycle. We use this as justification for part of our modifications to the
- * memory model when proving our model-checker's correctness.
