-/**
- * \file ir_sub_to_add_neg.cpp
- *
- * Breaks an ir_binop_sub expression down to add(op0, neg(op1))
- *
- * This simplifies expression reassociation, and for many backends
- * there is no subtract operation separate from adding the negation.
- * For backends with native subtract operations, they will probably
- * want to recognize add(op0, neg(op1)) or the other way around to
- * produce a subtract anyway.
