public interface Lowerable
extends NodeInterface

Interface implemented by nodes that can replace themselves with lower level nodes during a phase that transforms a graph to replace higher level nodes with lower level nodes.

Method Summary

Modifier and Type	Method and Description
ValueNode	asNode()
void	lower(LoweringTool tool) Expand this node into lower level nodes expressing the same semantics.

Method Detail

lower

void lower(LoweringTool tool)

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.
