ValueNode	canonical(CanonicalizerTool tool, ValueNode forX, ValueNode forY, ValueNode forZ) 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.
Stamp	foldStamp(Stamp stampX, Stamp stampY, Stamp stampZ) Compute an improved stamp for this node using the passed in stamps.

FusedMultiplyAddNode

public FusedMultiplyAddNode(ValueNode x,
                            ValueNode y,
                            ValueNode z)

foldStamp

public Stamp foldStamp(Stamp stampX,
                       Stamp stampY,
                       Stamp stampZ)

Description copied from class: TernaryNode

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

Specified by:

foldStamp in class TernaryNode

canonical

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

Description copied from interface: Canonicalizable.Ternary

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.Ternary<ValueNode>

generate

public void generate(NodeLIRBuilderTool builder,
                     ArithmeticLIRGeneratorTool gen)
