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.
