Method Detail

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

generate

public void generate(NodeLIRBuilderTool generator)

Specified by:

generate in interface LIRLowerable

memoryBarrier

public static void memoryBarrier(MembarNode.FenceKind fence)

memoryBarrier

public static void memoryBarrier(MembarNode.FenceKind fence,
                                 org.graalvm.word.LocationIdentity location)
