Constructor Detail

InvokeWithExceptionNode

public InvokeWithExceptionNode(CallTargetNode callTarget,
                               AbstractBeginNode exceptionEdge,
                               int bci)

Method Detail

afterClone

protected void afterClone(Node other)

Overrides:

afterClone in class Node

callTarget

public CallTargetNode callTarget()

Specified by:

callTarget in interface Invoke

methodCallTarget

public MethodCallTargetNode methodCallTarget()

isPolymorphic

public boolean isPolymorphic()

Description copied from interface: Invoke

True if this invocation is almost certainly polymorphic, false when in doubt.

Specified by:

isPolymorphic in interface Invoke

setPolymorphic

public void setPolymorphic(boolean value)

Specified by:

setPolymorphic in interface Invoke

setInlineControl

public void setInlineControl(Invoke.InlineControl control)

Specified by:

setInlineControl in interface Invoke

getInlineControl

public Invoke.InlineControl getInlineControl()

Specified by:

getInlineControl in interface Invoke

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this with a given Verbosity.

Overrides:

toString in class Node

bci

public int bci()

Specified by:

bci in interface DeoptBciSupplier

Returns:

the byte code index (BCI) associated with the node implementing this interface

setNext

public void setNext(FixedNode x)

Specified by:

setNext in interface Invoke

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

stateAfter

public FrameState stateAfter()

Description copied from interface: StateSplit

Gets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

stateAfter in interface StateSplit

setStateAfter

public void setStateAfter(FrameState stateAfter)

Description copied from interface: StateSplit

Sets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

setStateAfter in interface StateSplit

hasSideEffect

public boolean hasSideEffect()

Description copied from interface: StateSplit

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.

Specified by:

hasSideEffect in interface StateSplit

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

This method is used to determine which memory location is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentity in interface SingleMemoryKill

Returns:

the identity of the location killed by this node.

getDebugProperties

public Map<Object,Object> getDebugProperties(Map<Object,Object> map)

Description copied from class: Node

Fills a Map with properties of this for use in debugging (e.g., to view in the ideal graph visualizer). Subclasses overriding this method should also fill the map using their superclass.

Overrides:

getDebugProperties in class Node

setBci

public void setBci(int newBci)

Description copied from interface: DeoptBciSupplier

Remember the byte code index (BCI) for code generation or lowering purposes. For example, nodes lowering to foreign calls that can safepoint require a valid BCI for computations of the during-state of such a foreign call.

Specified by:

setBci in interface DeoptBciSupplier

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode

stateDuring

public FrameState stateDuring()

Specified by:

stateDuring in interface DeoptimizingNode.DeoptDuring

setStateDuring

public void setStateDuring(FrameState stateDuring)

Description copied from interface: DeoptimizingNode.DeoptDuring

Sets the FrameState describing the program state during the execution of this node.

Specified by:

setStateDuring in interface DeoptimizingNode.DeoptDuring

uncheckedStamp

public Stamp uncheckedStamp()

Description copied from interface: UncheckedInterfaceProvider

Returns a stamp containing information about interface types that has not been verified or null if no such stamp is available. A type check is needed before using informations from this stamp.

Specified by:

uncheckedStamp in interface UncheckedInterfaceProvider

setClassInit

public void setClassInit(ValueNode classInit)

Specified by:

setClassInit in interface Invoke

classInit

public ValueNode classInit()

Specified by:

classInit in interface Invoke

replaceWithInvoke

public InvokeNode replaceWithInvoke()

Replaces this InvokeWithExceptionNode with a normal InvokeNode. Kills the exception dispatch code.

replaceWithNonThrowing

public InvokeNode replaceWithNonThrowing()

Description copied from class: WithExceptionNode

Converts this node into a variant with the same semantics but without an exception edge. The default implementation does not change the node class, but instead only marks the exception path as unused. A later lowering of the node needs to take care of the actual removal of the exception path, e.g., by lowering into a ForeignCallNode.

Overrides:

replaceWithNonThrowing in class WithExceptionNode

simplify

public void simplify(SimplifierTool tool)

Specified by:

simplify in interface Simplifiable

estimatedNodeCycles

public NodeCycles estimatedNodeCycles()

Overrides:

estimatedNodeCycles in class Node

dynamicNodeSizeEstimate

protected NodeSize dynamicNodeSizeEstimate()

Description copied from class: Node

Node subclasses should override this method if they need to specify a dynamically calculated NodeSize value. If the node size is static please use NodeInfo.size(). NOTE: When overriding this method, make sure that *all* field reads are null checked (even if Java semantics seemingly make the value of the field non-null). This is necessary because node size estimates are needed even during graph decoding which, for some nodes, first reflectively creates a stub and then later, reflectively, populates its fields. This method could be invoked between these two points. For this reason, when overriding this method assume that all fields can and will be null.

Overrides:

dynamicNodeSizeEstimate in class Node

Returns:

The estimated node size for this node.
