Constructor Detail

HotSpotTruffleCompilerImpl

public HotSpotTruffleCompilerImpl(HotSpotGraalRuntimeProvider hotspotGraalRuntime,
                                  TruffleCompilerConfiguration config)

Method Detail

create

public static HotSpotTruffleCompilerImpl create(TruffleCompilerRuntime runtime)

createCompilationIdentifier

public TruffleCompilationIdentifier createCompilationIdentifier(CompilableTruffleAST compilable)

Description copied from class: TruffleCompilerImpl

Creates a new CompilationIdentifier for compilable. Implementations of this method must guarantee that the CompilationIdentifier.Verbosity.ID for each returned value is unique.

Specified by:

createCompilationIdentifier in class TruffleCompilerImpl

getCompilerConfigurationName

public String getCompilerConfigurationName()

Description copied from interface: TruffleCompiler

Returns a unique name for the configuration in use by this compiler.

Specified by:

getCompilerConfigurationName in interface TruffleCompiler

createDebugContext

protected DebugContext createDebugContext(OptionValues options,
                                          CompilationIdentifier compilationId,
                                          CompilableTruffleAST compilable,
                                          PrintStream logStream)

Specified by:

createDebugContext in class TruffleCompilerImpl

createPartialEvaluator

protected HotSpotPartialEvaluator createPartialEvaluator(TruffleCompilerConfiguration configuration)

Description copied from class: TruffleCompilerImpl

Creates the partial evaluator used by this compiler.

Specified by:

createPartialEvaluator in class TruffleCompilerImpl

createGraphBuilderSuite

public PhaseSuite<HighTierContext> createGraphBuilderSuite(TruffleTierConfiguration tier)

Specified by:

createGraphBuilderSuite in class TruffleCompilerImpl

installTruffleCallBoundaryMethod

public void installTruffleCallBoundaryMethod(ResolvedJavaMethod method)

Compiles a method denoted as an entry point to truffle code invoked by the runtime. The compiled code has a special entry point to jump to Truffle-compiled code generated by an TruffleCallBoundaryInstrumentationFactory.

Specified by:

installTruffleCallBoundaryMethod in interface HotSpotTruffleCompiler

installTruffleReservedOopMethod

public void installTruffleReservedOopMethod(ResolvedJavaMethod method)

Compiles a method with fast thread local Truffle intrinsics. This allows to access the jvmci reserved oop field. See HotSpotFastThreadLocal.

Specified by:

installTruffleReservedOopMethod in interface HotSpotTruffleCompiler

pendingTransferToInterpreterOffset

public int pendingTransferToInterpreterOffset(CompilableTruffleAST compilable)

Specified by:

pendingTransferToInterpreterOffset in interface HotSpotTruffleCompiler

getDebugOutputDirectory

protected DiagnosticsOutputDirectory getDebugOutputDirectory()

Specified by:

getDebugOutputDirectory in class TruffleCompilerImpl

getCompilationProblemsPerAction

protected Map<CompilationWrapper.ExceptionAction,Integer> getCompilationProblemsPerAction()

Description copied from class: TruffleCompilerImpl

Gets the map used to count the number of compilation failures or bailouts handled by each action.

Specified by:

getCompilationProblemsPerAction in class TruffleCompilerImpl

See Also:

CompilationWrapper.CompilationWrapper(DiagnosticsOutputDirectory, Map)

createInstalledCode

protected InstalledCode createInstalledCode(CompilableTruffleAST compilable)

Specified by:

createInstalledCode in class TruffleCompilerImpl

soleExecutionEntryPoint

protected boolean soleExecutionEntryPoint(InstalledCode installedCode)

Default nmethods installed by Graal are executed through a Method::_code field pointing to them. That is, they can be executed even when the HotSpotNmethod created during code installation dies. As such, these objects must remain strongly reachable from OptimizedAssumptions they depend on.

Overrides:

soleExecutionEntryPoint in class TruffleCompilerImpl

See Also:

OptimizedAssumptionDependency.soleExecutionEntryPoint()

exitHostVM

protected void exitHostVM(int status)

Description copied from class: TruffleCompilerImpl

Calls System.exit(int) in the runtime embedding the Graal compiler. This will be a different runtime than Graal's runtime in the case of libgraal.

Overrides:

exitHostVM in class TruffleCompilerImpl

createCompilationResult

protected CompilationResult createCompilationResult(String name,
                                                    CompilationIdentifier compilationIdentifier,
                                                    CompilableTruffleAST compilable)

Description copied from class: TruffleCompilerImpl

Creates the CompilationResult to be used for a Truffle compilation.

Specified by:

createCompilationResult in class TruffleCompilerImpl

afterCodeInstallation

protected void afterCodeInstallation(CompilationResult result,
                                     InstalledCode installedCode)

Notifies this object once installedCode has been installed in the code cache.

Overrides:

afterCodeInstallation in class TruffleCompilerImpl

Parameters:

result - the result of compilation

installedCode - code that has just been installed in the code cache

getCompilable

protected CompilableTruffleAST getCompilable(CompilationResult result)

Description copied from class: TruffleCompilerImpl

Gets the CompilableTruffleAST associated with result.

Overrides:

getCompilable in class TruffleCompilerImpl

Parameters:

result - a CompilationResult that may have a non-null CompilableTruffleAST associated with it

getPartialEvaluator
