public interface MemoryAccess
extends ValueNodeInterface

This interface marks nodes that access some memory location. Such nodes are either fixed before floating read nodes or part of the memory graph.

Method Detail

getLocationIdentity

org.graalvm.word.LocationIdentity getLocationIdentity()

getLastLocationAccess

default MemoryKill getLastLocationAccess()

Returns:

a MemoryKill that represents the last memory state in the memory graph for the LocationIdentity returned by MemoryAccess.getLocationIdentity()

setLastLocationAccess

default void setLastLocationAccess(MemoryKill lla)

Parameters:

lla - the MemoryKill that represents the last kill of the LocationIdentity returned by MemoryAccess.getLocationIdentity()
