Class MultiTypeGuardInlineInfo

java.lang.Object

org.graalvm.compiler.phases.common.inlining.info.AbstractInlineInfo

org.graalvm.compiler.phases.common.inlining.info.MultiTypeGuardInlineInfo

All Implemented Interfaces:

InlineInfo

public class MultiTypeGuardInlineInfo
extends AbstractInlineInfo

Polymorphic inlining of m methods with n type checks (n ≥ m) in case that the profiling information suggests a reasonable amount of different receiver types and different methods. If an unknown type is encountered a deoptimization is triggered.

Method Detail

numberOfMethods

public int numberOfMethods()

Description copied from interface: InlineInfo

Returns the number of methods that may be inlined by the invocation. This may be more than one in the case of a invocation profile showing a number of "hot" concrete methods dispatched to by the invocation.

methodAt

public ResolvedJavaMethod methodAt(int index)

inlineableElementAt

public Inlineable inlineableElementAt(int index)

probabilityAt

public double probabilityAt(int index)

relevanceAt

public double relevanceAt(int index)

setInlinableElement

public void setInlinableElement(int index,
                                Inlineable inlineableElement)

inline

public org.graalvm.collections.EconomicSet<Node> inline(CoreProviders providers,
                                                        String reason)

Description copied from interface: InlineInfo

Performs the inlining described by this object and returns the node that represents the return value of the inlined method (or null for void methods and methods that have no non-exceptional exit).

Returns:

a collection of nodes that need to be canonicalized after the inlining

shouldInline

public boolean shouldInline()

doInline

protected org.graalvm.collections.EconomicSet<Node> doInline(int index,
                                                             Invoke invokeForInlining,
                                                             String reason)

tryToDevirtualizeInvoke

public void tryToDevirtualizeInvoke(Providers providers)

Description copied from interface: InlineInfo

Try to make the call static bindable to avoid interface and virtual method calls.

toString

public String toString()

Overrides:

toString in class Object
