Method Summary

Modifier and Type	Method and Description
Node	canonical(CanonicalizerTool tool, ValueNode forX, ValueNode forY) 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.
static Stamp	computeStamp(Stamp stampX, Stamp stampY)
Stamp	foldStamp(Stamp stampX, Stamp stampY) Compute an improved for this node using the passed in stamps.

CopySignNode

Method Detail

computeStamp

public static Stamp computeStamp(Stamp stampX,
                                 Stamp stampY)

foldStamp

public Stamp foldStamp(Stamp stampX,
                       Stamp stampY)

Description copied from class: BinaryNode

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

Specified by:

foldStamp in class BinaryNode

canonical

public Node canonical(CanonicalizerTool tool,
                      ValueNode forX,
                      ValueNode forY)

Description copied from interface: Canonicalizable.Binary

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.Binary<ValueNode>

generate

public void generate(NodeLIRBuilderTool nodeValueMap,
                     ArithmeticLIRGeneratorTool gen)

Specified by:

generate in interface ArithmeticLIRLowerable
