Method Summary

Modifier and Type	Method and Description
ValueNode	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.

boolean	isNarrowable(int resultBits) Check whether this operation can be narrowed to resultBits bit without loss of precision.

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:

isNarrowable

public boolean isNarrowable(int resultBits)

Description copied from interface: NarrowableArithmeticNode

Check whether this operation can be narrowed to resultBits bit without loss of precision.

Specified by:

isNarrowable in interface NarrowableArithmeticNode

Overrides:

isNarrowable in class ShiftNode<ArithmeticOpTable.ShiftOp.UShr>
