Node |
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. |
Stamp |
foldStamp(Stamp newStamp)
Compute an improved for this node using the passed in stamp.

ArithmeticLIRGeneratorTool gen) |
