Class CallsiteHolderExplorable

java.lang.Object

org.graalvm.compiler.phases.common.inlining.walker.CallsiteHolder

org.graalvm.compiler.phases.common.inlining.walker.CallsiteHolderExplorable

public final class CallsiteHolderExplorable
extends CallsiteHolder

A CallsiteHolder whose graph has been copied already and thus can be modified without affecting the original (usually cached) version.

An instance of this class is derived from an InlineableGraph and contains a subset of the information there: just the Invoke nodes from it. Such nodes are candidates for depth-first search of further inlining opportunities (thus the adjective "explorable" given to this class)

CallsiteHolderExplorable

public CallsiteHolderExplorable(StructuredGraph graph,
                                double probability,
                                double relevance,

                                LinkedList<Invoke> invokes)

Method Detail

getFixedParams

public org.graalvm.collections.EconomicSet<ParameterNode> getFixedParams()

Parameters for which the callsite targeting CallsiteHolderExplorable.graph() provides "fixed" arguments. That callsite isn't referenced by this instance. Instead, it belongs to the graph of the caller of this CallsiteHolderExplorable

Constant arguments don't contribute to fixed-params: those params have been removed already, see InlineableGraph.

Instead, fixed-params are those receiving freshly instantiated arguments (possibly instantiated several levels up in the call-hierarchy)

repOK

public boolean repOK()

method

public ResolvedJavaMethod method()

Description copied from class: CallsiteHolder

Gets the method associated with the graph represented by this object.

Specified by:

method in class CallsiteHolder

hasRemainingInvokes

public boolean hasRemainingInvokes()

Description copied from class: CallsiteHolder

The stack realized by InliningData grows upon InliningData.moveForward() deciding to explore (depth-first) a callsite of the graph associated to this CallsiteHolder. The list of not-yet-considered callsites is managed by CallsiteHolderExplorable, and this method reports whether any such candidates remain.

Specified by:

hasRemainingInvokes in class CallsiteHolder

Description copied from class: CallsiteHolder

The graph about which this object contains inlining information.
