Method Detail

getLocationIdentity

public LocationIdentity getLocationIdentity()

Description copied from interface: MemoryCheckpoint.Single

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:

getLocationIdentity in interface MemoryAccess

Specified by:

getLocationIdentity in interface MemoryCheckpoint.Single

Overrides:

getLocationIdentity in class BasicArrayCopyNode

Returns:

the identity of the location killed by this node.

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

Overrides:

lower in class BasicArrayCopyNode
