Method Detail

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

values

public NodeInputList<ValueNode> values()

Specified by:

values in class PhiNode

valueDescription

protected String valueDescription()

Description copied from class: PhiNode

String describing the kind of value this Phi merges. Used by PhiNode.toString(Verbosity) and dumping.

Overrides:

valueDescription in class PhiNode

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 PhiNode duplicateOn(AbstractMergeNode newMerge)

Description copied from class: PhiNode

Create a phi of the same kind on the given merge.

Specified by:

duplicateOn in class PhiNode

Parameters:

newMerge - the merge to use for the newly created phi

createProxyFor

public ProxyNode createProxyFor(LoopExitNode lex)

Specified by:

createProxyFor in class PhiNode
