Class HotSpotTruffleRuntime

java.lang.Object

com.oracle.truffle.runtime.OptimizedTruffleRuntime

com.oracle.truffle.runtime.hotspot.HotSpotTruffleRuntime

All Implemented Interfaces:

com.oracle.truffle.api.TruffleRuntime, com.oracle.truffle.compiler.TruffleCompilerRuntime

public final class HotSpotTruffleRuntime
extends OptimizedTruffleRuntime

HotSpot specific implementation of a Graal-enabled Truffle runtime. This class contains functionality for interfacing with a HotSpot-based Truffle compiler, independent of where the compiler resides (i.e., co-located in the HotSpot heap or running in a native-image shared library).

getThreadLocalHandshake

public com.oracle.truffle.api.impl.ThreadLocalHandshake getThreadLocalHandshake()

Specified by:

getThreadLocalHandshake in class OptimizedTruffleRuntime

getStackIntrospection

protected jdk.vm.ci.code.stack.StackIntrospection getStackIntrospection()

Specified by:

getStackIntrospection in class OptimizedTruffleRuntime

getTruffleCompiler

public com.oracle.truffle.compiler.TruffleCompiler getTruffleCompiler(com.oracle.truffle.compiler.TruffleCompilable compilable)

This is called reflectively from the compiler side in HotSpotTruffleHostEnvironment.

Specified by:

getTruffleCompiler in class OptimizedTruffleRuntime

resetCompiler

public void resetCompiler()

onEngineCreated

protected void onEngineCreated(EngineData engine)

Overrides:

onEngineCreated in class OptimizedTruffleRuntime

createOptimizedCallTarget

public OptimizedCallTarget createOptimizedCallTarget(OptimizedCallTarget source,
 com.oracle.truffle.api.nodes.RootNode rootNode)

Specified by:

createOptimizedCallTarget in class OptimizedTruffleRuntime

createInitializationCallTarget

protected OptimizedCallTarget createInitializationCallTarget(EngineData engine)

Specified by:

onCodeInstallation

public void onCodeInstallation(com.oracle.truffle.compiler.TruffleCompilable compilable,
 jdk.vm.ci.code.InstalledCode installedCode)

createSpeculationLog

public jdk.vm.ci.meta.SpeculationLog createSpeculationLog()

Creates a log that HotSpotSpeculationLog#managesFailedSpeculations() manages a native failed speculations list. An important invariant is that an nmethod compiled with this log can never be executing once the log object dies. When the log object dies, it frees the failed speculations list thus invalidating the HotSpotSpeculationLog#getFailedSpeculationsAddress() failed speculations address embedded in the nmethod. If the nmethod were to execute after this point and fail a speculation, it would append the failed speculation to the already freed list.

Truffle ensures this cannot happen as it only attaches managed speculation logs to OptimizedCallTargets and OptimizedOSRLoopNodes. Executions of nmethods compiled for an OptimizedCallTarget or OptimizedOSRLoopNode object will have a strong reference to the object (i.e., as the receiver). This guarantees that such an nmethod cannot be executing after the object has died.

Specified by:

createSpeculationLog in class OptimizedTruffleRuntime

setDontInlineCallBoundaryMethod

public static void setDontInlineCallBoundaryMethod(List<jdk.vm.ci.meta.ResolvedJavaMethod> callBoundaryMethods)

getCompileQueue

public BackgroundCompileQueue getCompileQueue()

Specified by:

getCompileQueue in class OptimizedTruffleRuntime

bypassedInstalledCode

public void bypassedInstalledCode(OptimizedCallTarget target)

Description copied from class: OptimizedTruffleRuntime

Notifies this runtime when a Truffle AST is being executed in the Truffle interpreter even though compiled code is available for the AST. If this runtime uses a special entry point to switch to compiled Truffle code, then this means the code with the special entry point was deoptimized or otherwise removed from the code cache and needs to be re-installed.

Overrides:

bypassedInstalledCode in class OptimizedTruffleRuntime

bypassedReservedOop

public boolean bypassedReservedOop()

getKnownMethods

public OptimizedTruffleRuntime.KnownMethods getKnownMethods()

Overrides:
