processWorkSet

private void processWorkSet(StructuredGraph graph)

processNode

private void processNode(Node node)

tryGlobalValueNumbering

public boolean tryGlobalValueNumbering(Node node,

getCanonicalizeableContractAssertion

private AutoCloseable getCanonicalizeableContractAssertion(Node node)

tryCanonicalize

public boolean tryCanonicalize(Node node,
                               NodeClass<?> nodeClass)

performReplacement

private boolean performReplacement(Node node,
                                   Node newCanonical)

tryInferStamp

private boolean tryInferStamp(ValueNode node)

Calls ValueNode.inferStamp() on the node and, if it returns true (which means that the stamp has changed), re-queues the node's usages. If the stamp has changed then this method also checks if the stamp now describes a constant integer value, in which case the node is replaced with a constant.
