Constructor Detail

MemoryProxyNode

public MemoryProxyNode(MemoryKill value,
                       LoopExitNode proxyPoint,
                       org.graalvm.word.LocationIdentity locationIdentity)

Method Detail

setValue

public void setValue(MemoryKill newValue)

value

public ValueNode value()

Specified by:

value in class ProxyNode

createPhi

public PhiNode createPhi(AbstractMergeNode merge)

Specified by:

createPhi in class ProxyNode

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.

duplicateOn

public ProxyNode duplicateOn(LoopExitNode newProxyPoint,
                             ValueNode newOriginalNode)

Specified by:

duplicateOn in class ProxyNode
