- * \file ir_expression_flattening.cpp
- *
- * Takes the leaves of expression trees and makes them dereferences of
- * assignments of the leaves to temporaries, according to a predicate.
- *
- * This is used for breaking down matrix operations, where it's easier to
- * create a temporary and work on each of its vector components individually.
