Interface NodeWithIdentity

All Known Subinterfaces:

ControlFlowAnchored

All Known Implementing Classes:

BlackholeNode, ComputeObjectAddressNode, ControlFlowAnchorNode, ExplodeLoopNode, NewMultiArrayNode, OpaqueLogicNode, OpaqueNode, ValueAnchorNode, VirtualFrameAccessorNode, VirtualFrameClearNode, VirtualFrameCopyNode, VirtualFrameGetNode, VirtualFrameGetTagNode, VirtualFrameIsNode, VirtualFrameSetNode, VirtualFrameSwapNode

public interface NodeWithIdentity

Nodes that are marked with this interface have an implicit unique identity, i.e., two nodes are never treated as having equal data fields. This prevents optimizations like global value numbering or de-deduplication of such nodes.
