public PropagateDeoptimizeProbabilityPhase()

Method Detail

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<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.

run

protected void run(StructuredGraph graph,
                   CoreProviders context)

Specified by:

run in class BasePhase<CoreProviders>
