Class StrengthenStampsPhase

java.lang.Object

org.graalvm.compiler.phases.BasePhase<Object>

org.graalvm.compiler.phases.Phase

com.oracle.svm.hosted.phases.StrengthenStampsPhase

All Implemented Interfaces:

org.graalvm.compiler.phases.contract.PhaseSizeContract

public class StrengthenStampsPhase
extends org.graalvm.compiler.phases.Phase

Strengthens the stamp of nodes based on the static analysis result. The canonicalizer then propagates the improved stamp through the method and, for example, removes null-checks when the new stamp states that a value is non-null.
