Calls in replacements to methods matching one of these filters are elided. Only void methods are considered for elision. The use of "snippets" in name of the variable and system property is purely for legacy reasons.

Constructor Detail

NodeIntrinsificationPlugin

public NodeIntrinsificationPlugin(MetaAccessProvider metaAccess,
                                  NodeIntrinsificationPhase nodeIntrinsification,
                                  WordTypes wordTypes,

Method Detail

getMethodsElidedInSnippets

private static MethodFilter[] getMethodsElidedInSnippets()

handleInvoke

public boolean handleInvoke(GraphBuilderContext b,
                            ResolvedJavaMethod method,
                            ValueNode[] args)

Description copied from interface: NodePlugin

Handle the parsing of a method invocation bytecode to a method that can be bound statically. If the method returns true, it must push a value as the result of the method invocation using the return kind of the method.

Specified by:

handleInvoke in interface NodePlugin

Parameters:

b - the context

method - the statically bound, invoked method

args - the arguments of the method invocation

Returns:

true if the plugin handles the invocation, false otherwise

reportIntrinsificationFailure

private static boolean reportIntrinsificationFailure(GraphBuilderContext b,
                                                     ResolvedJavaMethod method,
