All Implemented Interfaces:

Node.ValueNumberable, Canonicalizable, Canonicalizable.Unary<ValueNode>, ArithmeticOperation, ArithmeticLIRLowerable, Cloneable, Formattable, KindProvider

public final class ReinterpretNode
extends UnaryNode
implements ArithmeticLIRLowerable

The ReinterpretNode class represents a reinterpreting conversion that changes the stamp of a primitive value to some other incompatible stamp. The new stamp must have the same width as the old stamp.
