UnsignedDivNode

UnsignedDivNode

protected UnsignedDivNode(NodeClass<? extends UnsignedDivNode> c,
                          ValueNode x,
                          ValueNode y)

Method Detail

canonical

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

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:

canonical in interface Canonicalizable.Binary<ValueNode>

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode

unsignedDivide

public static int unsignedDivide(int a,
                                 int b)

unsignedDivide

public static long unsignedDivide(long a,
                                  long b)
