public interface AddressableMemoryAccess
extends MemoryAccess

A special form of MemoryAccess exposing the AddressNode representing the LocationIdentity touched by this memory access. Typically used during a later stage in the compilation pipeline.

Method Summary

Modifier and Type	Method and Description
boolean	canNullCheck() Determines if the memory touch operation represented by this node can use OS level semantics for representing the null check of the memory location with an operating system level trap.
