Field Detail

replacements

protected final ReplacementsImpl replacements

The replacements object that the graphs are created for.

method

protected final ResolvedJavaMethod method

The method for which a graph is being created.

substitutedMethod

protected final ResolvedJavaMethod substitutedMethod

The original method which method is substituting. Calls to method or substitutedMethod will be replaced with a forced inline of substitutedMethod.

Constructor Detail

GraphMaker

protected GraphMaker(ReplacementsImpl replacements,
                     ResolvedJavaMethod substitute,
                     ResolvedJavaMethod substitutedMethod)

Method Detail

makeGraph

public StructuredGraph makeGraph(Object[] args)

finalizeGraph

protected void finalizeGraph(StructuredGraph graph)

Does final processing of a snippet graph.

hasSideEffect

private boolean hasSideEffect(Node node)

Filter nodes which have side effects and shouldn't be deleted from snippets when converting deoptimizations to guards. Currently this only allows exception constructors to be eliminated to cover the case when Java assertions are in the inlined code.

Parameters:

node -

Returns:

true for nodes that have side effects and are unsafe to delete

buildInitialGraph

protected StructuredGraph buildInitialGraph(ResolvedJavaMethod methodToParse,
                                            Object[] args)

Builds the initial graph for a snippet.

createGraphBuilder

protected GraphBuilderPhase.Instance createGraphBuilder(MetaAccessProvider metaAccess,
                                                        StampProvider stampProvider,
                                                        ConstantReflectionProvider constantReflection,
                                                        GraphBuilderConfiguration graphBuilderConfig,
                                                        OptimisticOptimizations optimisticOpts,
                                                        IntrinsicContext initialIntrinsicContext)
