public List<VirtualObjectNode> getVirtualObjects()

getValues

public List<ValueNode> getValues()

getLocks

public List<MonitorIdNode> getLocks(int objIndex)

getEnsureVirtual

public List<Boolean> getEnsureVirtual()

verify

public boolean verify()

Overrides:

verify in class FixedNode

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

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.

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

Specified by:

getLocationIdentity in interface MemoryAccess

afterClone

public void afterClone(Node other)

Overrides:

afterClone in class Node

addLocks

public void addLocks(List<MonitorIdNode> monitorIds)

virtualize

public void virtualize(VirtualizerTool tool)

Description copied from interface: Virtualizable

A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized. All modifications must be made through the supplied tool, and not directly on the node, because by the time this method is called the virtualized/non-virtualized state is still speculative and might not hold because of loops, etc.

Specified by:

virtualize in interface Virtualizable

Parameters:

tool - the tool used to describe the effects of 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

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.
