Class GraphChangeMonitoringPhase<C extends PhaseContext>

java.lang.Object

com.oracle.graal.phases.BasePhase<C>

com.oracle.graal.phases.PhaseSuite<C>

com.oracle.graal.compiler.phases.GraphChangeMonitoringPhase<C>

Type Parameters:

C -

public class GraphChangeMonitoringPhase<C extends PhaseContext>
extends PhaseSuite<C>

A utility phase for detecting when a phase would change the graph and reporting extra information about the effects. The phase is first run on a copy of the graph and if a change in that graph is detected then it's rerun on the original graph inside a new debug scope under GraphChangeMonitoringPhase. The message argument can be used to distinguish between the same phase run at different points.
