-/**
- * \file ir_mod_to_fract.cpp
- *
- * Breaks an ir_unop_mod expression down to (op1 * fract(op0 / op1))
- *
- * Many GPUs don't have a MOD instruction (945 and 965 included), and
- * if we have to break it down like this anyway, it gives an
- * opportunity to do things like constant fold the (1.0 / op1) easily.
