public void onCompilationDequeued(OptimizedCallTarget target,
                                  Object source,
                                  CharSequence reason,
                                  int tier)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object after target is removed from the compilation queue.

Parameters:

target - the call target that has just been removed from the compilation queue

source - the source object that caused the compilation to be unqueued. For example the source Node object. May be null.

reason - a textual description of the reason why the compilation was unqueued. May be null.

tier - Which compilation tier is in question.

onCompilationInvalidated

public void onCompilationInvalidated(OptimizedCallTarget target,
                                     Object source,
                                     CharSequence reason)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when target is invalidated.

Parameters:

target - the call target whose compiled code was just invalidated

source - the source object that caused the compilation to be invalidated. For example the source Node object. May be null.

reason - a textual description of the reason why the compilation was invalidated. May be null.

onCompilationStarted

public void onCompilationStarted(OptimizedCallTarget target,
                                 TruffleCompilationTask task)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when compilation of target is about to start.

Parameters:

target - the call target about to be compiled

task - which compilation task is in question.

onCompilationTruffleTierFinished

public void onCompilationTruffleTierFinished(OptimizedCallTarget target,
                                             TruffleInlining inliningDecision,
                                             TruffleCompilerListener.GraphInfo graph)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when compilation of target has completed partial evaluation and is about to perform compilation of the graph produced by partial evaluation.

Parameters:

target - the call target being compiled

inliningDecision - the inlining plan used during partial evaluation

graph - access to compiler graph info

onCompilationGraalTierFinished

public void onCompilationGraalTierFinished(OptimizedCallTarget target,
                                           TruffleCompilerListener.GraphInfo graph)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when Graal compilation of a call target completes. Graal compilation occurs between GraalTruffleRuntimeListener.onCompilationTruffleTierFinished(org.graalvm.compiler.truffle.runtime.OptimizedCallTarget, org.graalvm.compiler.truffle.runtime.TruffleInlining, org.graalvm.compiler.truffle.common.TruffleCompilerListener.GraphInfo) and code installation.

Parameters:

graph - the graph representing target

onCompilationSuccess

public void onCompilationSuccess(OptimizedCallTarget target,
                                 TruffleInlining inliningDecision,
                                 TruffleCompilerListener.GraphInfo graph,

                                 int tier)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when compilation of target succeeds.

Parameters:

target - the call target whose compilation succeeded

inliningDecision - the inlining plan used during the compilation

graph - access to compiler graph info

result - access to compilation result info

tier - Which compilation tier is in question.

onCompilationFailed

public void onCompilationFailed(OptimizedCallTarget target,
                                String reason,
                                boolean bailout,

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object when compilation of target fails.

Parameters:

target - the call target whose compilation failed

reason - a description of the failure

bailout - specifies whether the failure was a bailout or an error in the compiler. A bailout means the compiler aborted the compilation based on some of property of target (e.g., too big). A non-bailout means an unexpected error in the compiler itself.

permanentBailout - specifies if a bailout is due to a condition that probably won't change if the target is compiled again. This value is meaningless if bailout == false.

tier - Which compilation tier is in question.

onEngineClosed

public void onEngineClosed(EngineData runtimeData)

Description copied from interface: GraalTruffleRuntimeListener

Notifies this object an engine using the GraalTruffleRuntime was closed.

Parameters:

runtimeData - the engine's compiler configuration
