Field Detail

outer

public final GraphDecoder.LoopScope outer

loopDepth

public final int loopDepth

loopIteration

public final int loopIteration

nextIterations

public Deque<GraphDecoder.LoopScope> nextIterations

Upcoming loop iterations during loop explosions that have not been processed yet. Only used when GraphDecoder.MethodScope.loopExplosion is not GraphDecoder.LoopExplosionKind.NONE.

iterationStates

public final Map<GraphDecoder.LoopExplosionState,GraphDecoder.LoopExplosionState> iterationStates

Information about already processed loop iterations for state merging during loop explosion. Only used when GraphDecoder.MethodScope.loopExplosion is GraphDecoder.LoopExplosionKind.MERGE_EXPLODE.

loopBeginOrderId

public final int loopBeginOrderId

nodesToProcess

public final BitSet nodesToProcess

The worklist of fixed nodes to process. Since we already the correct processing order from the orderId, we just set the orderId bit in the bitset when a node is ready for processing. The lowest set bit is the next node to process.

createdNodes

public final Node[] createdNodes

Nodes that have been created, indexed by the orderId.

initialCreatedNodes

public final Node[] initialCreatedNodes

Nodes that have been created in outer loop scopes and existed before starting to process this loop, indexed by the orderId.

LoopScope

protected LoopScope(GraphDecoder.MethodScope methodScope)

LoopScope

                    int loopDepth,
