Class BasePhase<C>

java.lang.Object

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

Direct Known Subclasses:

AbstractInliningPhase, CanonicalizerPhase, ConvertDeoptimizeToGuardPhase, DeoptimizationGroupingPhase, EffectsPhase, GraphBuilderPhase, GuardLoweringPhase, IterativeConditionalEliminationPhase, LoadJavaMirrorWithKlassPhase, LoopFullUnrollPhase, LoopSafepointEliminationPhase, LoweringPhase, Phase, PhaseSuite, UseTrappingNullChecksPhase, VerifyPhase

public abstract class BasePhase<C>
extends Object

Base class for all compiler phases. Subclasses should be stateless. There will be one global instance for each compiler phase that is shared for all compilations. VM-, target- and compilation-specific data can be passed with a context object.
