Package org.qbicc.plugin.opt

Class FinalFieldLoadOptimizer

java.lang.Object

org.qbicc.graph.DelegatingBasicBlockBuilder

org.qbicc.plugin.opt.FinalFieldLoadOptimizer

All Implemented Interfaces:

Locatable, ProgramLocatable, BasicBlockBuilder

public class FinalFieldLoadOptimizer
extends DelegatingBasicBlockBuilder

This optimization is run during the ANALYZE phase and replaces loads of reallyFinal fields with their constant values using the build-time heap constructed by the interpreter during the ADD phase. It optimizes static field and instance fields on ObjectLiterals.
