TYPE

public static final NodeClass<UnaryArithmeticNode> TYPE

Constructor Detail

UnaryArithmeticNode

protected UnaryArithmeticNode(NodeClass<? extends UnaryArithmeticNode<OP>> c,
                              ArithmeticOpTable.UnaryOp<OP> opForStampComputation,
                              ValueNode value)

Method Detail

getOp

protected abstract ArithmeticOpTable.UnaryOp<OP> getOp(ArithmeticOpTable table)

getOp

protected final ArithmeticOpTable.UnaryOp<OP> getOp(ValueNode forValue)

getArithmeticOp

public final ArithmeticOpTable.UnaryOp<OP> getArithmeticOp()

Specified by:

getArithmeticOp in interface ArithmeticOperation

foldStamp

public Stamp foldStamp(Stamp newStamp)

Description copied from class: UnaryNode

Compute an improved for this node using the passed in stamp. The stamp must be compatible with the current value of UnaryNode.value. This code is used to provide the default implementation of UnaryNode.inferStamp() and may be used by external optimizations.

Overrides:

foldStamp in class UnaryNode

canonical

public ValueNode canonical(CanonicalizerTool tool,
                           ValueNode forValue)

Description copied from interface: Canonicalizable.Unary

Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.

Specified by:

canonical in interface Canonicalizable.Unary<ValueNode>

findSynonym

protected static <OP> ValueNode findSynonym(ValueNode forValue,
                                            ArithmeticOpTable.UnaryOp<OP> op)
