The base classes for phases that always want to apply CanonicalizerPhase.applyIncremental(org.graalvm.compiler.nodes.StructuredGraph, org.graalvm.compiler.nodes.spi.CoreProviders, org.graalvm.compiler.graph.Graph.Mark) to a graph after the phase has been applied if the graph changed.

Method Summary

Modifier and Type	Method and Description
protected BasePhase.ApplyScope	applyScope(StructuredGraph graph, C context) Return an BasePhase.ApplyScope which will surround all the work performed by the call to BasePhase.run(org.graalvm.compiler.nodes.StructuredGraph, C) in BasePhase.apply(StructuredGraph, Object, boolean).
Optional<BasePhase.NotApplicable>	canApply(GraphState graphState) Checks if all the preconditions to BasePhase.apply(StructuredGraph, Object, boolean) the phase are met.
void	updateGraphState(GraphState graphState) Applies all the changes on the GraphState caused by BasePhase.apply(StructuredGraph, Object, boolean).

Constructor Detail

PostRunCanonicalizationPhase

public PostRunCanonicalizationPhase(CanonicalizerPhase canonicalizer)

Primary constructor for incremental canonicalization. Subclasses must provide a non-null CanonicalizerPhase

Method Detail

applyScope

protected BasePhase.ApplyScope applyScope(StructuredGraph graph,
                                          C context)

Description copied from class: BasePhase

Return an BasePhase.ApplyScope which will surround all the work performed by the call to BasePhase.run(org.graalvm.compiler.nodes.StructuredGraph, C) in BasePhase.apply(StructuredGraph, Object, boolean). This allows subclaseses to inject work which will performed before and after the application of this phase.

Overrides:

applyScope in class BasePhase<C extends CoreProviders>

canApply

public Optional<BasePhase.NotApplicable> canApply(GraphState graphState)

Description copied from class: BasePhase

Checks if all the preconditions to BasePhase.apply(StructuredGraph, Object, boolean) the phase are met.

Overrides:

canApply in class BasePhase<C extends CoreProviders>

Parameters:

graphState - represents the state of the StructuredGraph used for compilation and contains the required information to determine if a phase can be applied.

Returns:

Optional.empty() if all the checks pass, Optional#of(NotApplicable) containing why this phase is not applicable on this graphState otherwise.

updateGraphState

public void updateGraphState(GraphState graphState)

Description copied from class: BasePhase

Applies all the changes on the GraphState caused by BasePhase.apply(StructuredGraph, Object, boolean).

Overrides:

updateGraphState in class BasePhase<C extends CoreProviders>

Parameters:

graphState - represents the state of the StructuredGraph used for compilation.
