25 * @author Ben Titzer 25 * High-level intermediate representation (HIR).
26 *
27 * Classes that define the (High-level) Intermediate Representation (HIR) if the C1X compiler.
28 *
29 * HIR instances are created by processing Java bytecodes and are Directed Acyclic Graphs (DAGs). All nodes in
30 * an HIR graph are concrete subclasses of the abstract class {@link Value}. This indicates a property of HIR,
31 * namely that everything is a value, including instructions. This allows an operand for an instruction node to
32 * refer directly to the node that generated the value, which might, for example, be another instruction.
