All Implemented Interfaces:

PhaseSizeContract

public class FrameStateAssignmentPhase
extends Phase

This phase transfers FrameState nodes from StateSplit nodes to DeoptimizingNodes. This allow to enter the AFTER_FSA stage of the graph where no new node that may cause deoptimization can be introduced anymore.

This Phase processes the graph in post order, assigning the FrameState from the last StateSplit node to DeoptimizingNodes.
