Method Detail

getSource

public ValueNode getSource()

getSourcePosition

public ValueNode getSourcePosition()

getDestination

public ValueNode getDestination()

getDestinationPosition

public ValueNode getDestinationPosition()

getLength

public ValueNode getLength()

Description copied from class: ArrayRangeWriteNode

The length of the modified range.

Specified by:

getLength in class ArrayRangeWriteNode

getArray

public ValueNode getArray()

Description copied from class: ArrayRangeWriteNode

The array that is written to.

Specified by:

getArray in class ArrayRangeWriteNode

getIndex

public ValueNode getIndex()

Description copied from class: ArrayRangeWriteNode

The first modified index.

Specified by:

getIndex in class ArrayRangeWriteNode

isObjectArray

public boolean isObjectArray()

Description copied from class: ArrayRangeWriteNode

Return true if the written array is an object array, false if it is a primitive array.

Specified by:

isObjectArray in class ArrayRangeWriteNode

isInitialization

public boolean isInitialization()

Description copied from class: ArrayRangeWriteNode

Returns whether this write is the initialization of the written location. If it is true, the old value of the memory location is either uninitialized or zero. If it is false, the memory location is guaranteed to contain a valid value or zero.

Specified by:

isInitialization in class ArrayRangeWriteNode

arraycopy

public static void arraycopy(Object nonNullSrc,
                             int srcPos,
                             Object nonNullDest,
                             int destPos,
                             int length,
                             int unrolledLength,
                             Kind elementKind)

getUnrollLength

public int getUnrollLength()

getElementKind

public Kind getElementKind()

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

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

getLastLocationAccess

public MemoryNode getLastLocationAccess()

Specified by:

getLastLocationAccess in interface MemoryAccess

setLastLocationAccess

public void setLastLocationAccess(MemoryNode lla)

Specified by:

setLastLocationAccess in interface MemoryAccess

Parameters:

lla - the MemoryNode that represents the last kill of the location
