Method Detail

simplify

public void simplify(SimplifierTool tool)

Description copied from class: Node

Must be overridden by subclasses that implement Simplifiable. The implementation in Node exists to obviate the need to cast a node before invoking Simplifiable.simplify(SimplifierTool).

Specified by:

simplify in interface Simplifiable

Overrides:

simplify in class Node

prevBegin

public static AbstractBeginNode prevBegin(FixedNode from)

evacuateGuards

private void evacuateGuards(FixedNode evacuateFrom)

prepareDelete

public void prepareDelete()

prepareDelete

public void prepareDelete(FixedNode evacuateFrom)

removeProxies

public void removeProxies()

verify

public boolean verify()

Overrides:

verify in class FixedNode

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

guards

public NodeIterable<GuardNode> guards()

anchored

public NodeIterable<Node> anchored()

proxies

public NodeIterable<ProxyNode> proxies()

getBlockNodes

public NodeIterable<FixedNode> getBlockNodes()
