Methods

Modifier and Type	Method and Description
java.lang.Object	call(VirtualFrame frame, java.lang.Object[] arguments) Calls the inner CallTarget returned by DirectCallNode.getCurrentCallTarget().
boolean	cloneCallTarget() Clones the CallTarget instance returned by DirectCallNode.getCallTarget() in an uninitialized state for this DirectCallNode.
void	forceInlining() Enforces the runtime system to inline the CallTarget at this call site.
CallTarget	getClonedCallTarget() Returns the split CallTarget if this call site's CallTarget is cloned.
boolean	isCallTargetCloningAllowed() Returns true if the runtime system supports cloning and the RootNode returns true in RootNode.isCloningAllowed().
boolean	isInlinable() Returns true if the underlying runtime system supports inlining for the CallTarget in this DirectCallNode.
boolean	isInliningForced() Returns true if the CallTarget is forced to be inlined.

Method Detail

call

public java.lang.Object call(VirtualFrame frame,
                    java.lang.Object[] arguments)

Description copied from class: DirectCallNode

Calls the inner CallTarget returned by DirectCallNode.getCurrentCallTarget().

Specified by:

call in class DirectCallNode

arguments - the arguments that should be passed to the callee

Returns:

the return result of the call

forceInlining

public void forceInlining()

Description copied from class: DirectCallNode

Enforces the runtime system to inline the CallTarget at this call site. If the runtime system does not support inlining or it is already inlined this method has no effect. The runtime system may decide to not inline calls which were forced to inline.

Specified by:

forceInlining in class DirectCallNode

isInliningForced

public boolean isInliningForced()

Description copied from class: DirectCallNode

Returns true if the CallTarget is forced to be inlined. A DirectCallNode can either be inlined manually by invoking DirectCallNode.forceInlining() or by the runtime system which may at any point decide to inline.

Specified by:

isInliningForced in class DirectCallNode

Returns:

true if this method was inlined else false.

getClonedCallTarget

public CallTarget getClonedCallTarget()

Description copied from class: DirectCallNode

Returns the split CallTarget if this call site's CallTarget is cloned.

Specified by:

getClonedCallTarget in class DirectCallNode

Returns:

the split CallTarget

cloneCallTarget

public boolean cloneCallTarget()

Description copied from class: DirectCallNode

Clones the CallTarget instance returned by DirectCallNode.getCallTarget() in an uninitialized state for this DirectCallNode. This can be sensible to gather call site sensitive profiling information for this DirectCallNode. If DirectCallNode.isCallTargetCloningAllowed() returns false this method has no effect and returns false.

Specified by:

cloneCallTarget in class DirectCallNode

isCallTargetCloningAllowed

public boolean isCallTargetCloningAllowed()

Description copied from class: DirectCallNode

Returns true if the runtime system supports cloning and the RootNode returns true in RootNode.isCloningAllowed().

Specified by:

isCallTargetCloningAllowed in class DirectCallNode

Returns:

true if the target is allowed to be cloned.

isInlinable

public boolean isInlinable()

Description copied from class: DirectCallNode

Returns true if the underlying runtime system supports inlining for the CallTarget in this DirectCallNode.

Specified by:

isInlinable in class DirectCallNode

Returns:

true if inlining is supported.
