Method Summary

Modifier and Type	Method and Description
ValueNode	canonical(CanonicalizerTool tool, ValueNode forValue) 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.

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>

Overrides:

canonical in class UnaryArithmeticNode<ArithmeticOpTable.UnaryOp.Neg>

generate

public void generate(NodeValueMap nodeValueMap,
                     ArithmeticLIRGenerator gen)

Specified by:

generate in interface ArithmeticLIRLowerable
