Method Detail

getExternalInliningContext

public GraphBuilderContext.ExternalInliningContext getExternalInliningContext()

Specified by:

getExternalInliningContext in interface GraphBuilderContext

needsExplicitException

public boolean needsExplicitException()

Specified by:

needsExplicitException in interface GraphBuilderContext

Returns:

true if an explicit exception check should be emitted.

isParsingInvocationPlugin

public boolean isParsingInvocationPlugin()

Specified by:

isParsingInvocationPlugin in interface GraphBuilderContext

canDeferPlugin

public boolean canDeferPlugin(GeneratedInvocationPlugin plugin)

Fold and Node.NodeIntrinsic can be deferred during parsing/decoding. Only by the end of Snippet instantiation do they need to have been processed. This is how SVM handles snippets. They are parsed with plugins disabled and then encoded and stored in the image. When the snippet is needed at runtime the graph is decoded and the plugins are run during the decoding process. If they aren't handled at this point then they will never be handled.

Specified by:

canDeferPlugin in interface GraphBuilderTool

bailout

public BailoutException bailout(String string)

Specified by:

bailout in interface GraphBuilderContext

getGraph

public StructuredGraph getGraph()

Description copied from interface: GraphBuilderTool

Gets the graph being constructed.

Specified by:

getGraph in interface GraphBuilderTool

getDepth

public int getDepth()

Description copied from interface: GraphBuilderContext

Gets the inline depth of this context. A return value of 0 implies that this is the context for the parse root.

Specified by:

getDepth in interface GraphBuilderContext

recursiveInliningDepth

public int recursiveInliningDepth(ResolvedJavaMethod method)

Description copied from interface: GraphBuilderContext

Computes the recursive inlining depth of the provided method, i.e., counts how often the provided method is already in the GraphBuilderContext.getParent() chain starting at this context.

Specified by:

recursiveInliningDepth in interface GraphBuilderContext

getIntrinsic

public IntrinsicContext getIntrinsic()

Description copied from interface: GraphBuilderContext

Gets the intrinsic of the current parsing context or null if not parsing an intrinsic.

Specified by:

getIntrinsic in interface GraphBuilderContext

append

public <T extends ValueNode> T append(T value)

Description copied from interface: GraphBuilderTool

Adds the given node to the graph and also adds recursively all referenced inputs.

Specified by:

append in interface GraphBuilderTool

Parameters:

value - the node to be added to the graph

Returns:

either the node added or an equivalent node

push

public void push(JavaKind kind,
                 ValueNode value)

Description copied from interface: GraphBuilderContext

Pushes a given value to the frame state stack using an explicit kind. This should be used when value.getJavaKind() is different from the kind that the bytecode instruction currently being parsed pushes to the stack.

Specified by:

push in interface GraphBuilderContext

Parameters:

kind - the kind to use when type checking this operation

value - the value to push to the stack. The value must already have been appended.

handleReplacedInvoke

public Invoke handleReplacedInvoke(CallTargetNode.InvokeKind invokeKind,
                                   ResolvedJavaMethod targetMethod,
                                   ValueNode[] args,
                                   boolean inlineEverything)

Description copied from interface: GraphBuilderContext

Handles an invocation that a plugin determines can replace the original invocation (i.e., the one for which the plugin was applied). This applies all standard graph builder processing to the replaced invocation including applying any relevant plugins.

Specified by:

handleReplacedInvoke in interface GraphBuilderContext

Parameters:

invokeKind - the kind of the replacement invocation

targetMethod - the target of the replacement invocation

args - the arguments to the replacement invocation

inlineEverything - specifies if all invocations encountered in the scope of handling the replaced invoke are to be force inlined

handleReplacedInvoke

public void handleReplacedInvoke(CallTargetNode callTarget,
                                 JavaKind resultType)

Specified by:

handleReplacedInvoke in interface GraphBuilderContext

setStateAfter

public void setStateAfter(StateSplit stateSplit)

Description copied from interface: GraphBuilderContext

Creates a snap shot of the current frame state with the BCI of the instruction after the one currently being parsed and assigns it to a given side effect node.

Specified by:

setStateAfter in interface GraphBuilderContext

Parameters:

stateSplit - a side effect node just appended to the graph

getParent

public GraphBuilderContext getParent()

Description copied from interface: GraphBuilderContext
