Field Summary

Fields

Modifier and Type	Field and Description
GraphDecoder.LoopScope	callerLoopScope The loop that contains the call.
EncodedGraph	encodedGraph The encode graph that is decoded.
LoopExplosionPlugin.LoopExplosionKind	loopExplosion The kind of loop explosion to be performed during decoding.
MergeNode	loopExplosionHead The start of explosion, and the merge point for when irreducible loops are detected.
org.graalvm.collections.EconomicSet<Node>	loopExplosionMerges All merges created during loop explosion.
int	maxFixedNodeOrderId The highest node order id that a fixed node has in the EncodedGraph.
Graph.Mark	methodStartMark Mark for nodes that were present before the decoding of this method started.
int	orderIdWidth Number of bytes needed to encode an order id (order ids have a per-encoded-graph fixed size).
TypeReader	reader Access to the encoded graph.
List<ControlSinkNode>	returnAndUnwindNodes All return nodes encountered during decoding.

Field Detail

callerLoopScope

public final GraphDecoder.LoopScope callerLoopScope

The loop that contains the call. Only non-null during method inlining.

methodStartMark

public final Graph.Mark methodStartMark

Mark for nodes that were present before the decoding of this method started. Note that nodes that were decoded after the mark can still be part of an outer method, since floating nodes of outer methods are decoded lazily.

encodedGraph

public final EncodedGraph encodedGraph

The encode graph that is decoded.

maxFixedNodeOrderId

public final int maxFixedNodeOrderId

The highest node order id that a fixed node has in the EncodedGraph.

orderIdWidth

public final int orderIdWidth

Number of bytes needed to encode an order id (order ids have a per-encoded-graph fixed size).

reader

public final TypeReader reader

Access to the encoded graph.

loopExplosion

public final LoopExplosionPlugin.LoopExplosionKind loopExplosion

The kind of loop explosion to be performed during decoding.

returnAndUnwindNodes

public final List<ControlSinkNode> returnAndUnwindNodes

All return nodes encountered during decoding.

loopExplosionMerges

public final org.graalvm.collections.EconomicSet<Node> loopExplosionMerges

All merges created during loop explosion.

loopExplosionHead

public MergeNode loopExplosionHead

The start of explosion, and the merge point for when irreducible loops are detected. Only used when GraphDecoder.MethodScope.loopExplosion is LoopExplosionPlugin.LoopExplosionKind.MERGE_EXPLODE.
