org.qbicc.plugin.instanceofcheckcast.InstanceOfCheckCastBasicBlockBuilder

All Implemented Interfaces:

Locatable, ProgramLocatable, BasicBlockBuilder

public class InstanceOfCheckCastBasicBlockBuilder
extends DelegatingBasicBlockBuilder

A BasicBlockBuilder which replaces instanceof/checkcast operations with either inline code sequences that implement common cases or a call to the out-of-line VMHelper routine that provides a full implementation.
