Method Detail

bailout

public BailoutException bailout(String string)

Specified by:

bailout in interface GraphBuilderContext

getStampProvider

public StampProvider getStampProvider()

Specified by:

getStampProvider in interface GraphBuilderContext

getMetaAccess

public MetaAccessProvider getMetaAccess()

Specified by:

getMetaAccess in interface GraphBuilderContext

getConstantReflection

public ConstantReflectionProvider getConstantReflection()

Specified by:

getConstantReflection in interface GraphBuilderContext

getGraph

public StructuredGraph getGraph()

Description copied from interface: GraphBuilderContext

Gets the graph being constructed.

Specified by:

getGraph in interface GraphBuilderContext

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

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: GraphBuilderContext

Raw operation for adding a node to the graph when neither GraphBuilderContext.add(T) nor GraphBuilderContext.addPush(Kind, ValueNode) can be used.

Specified by:

append in interface GraphBuilderContext

Returns:

either the node added or an equivalent node

recursiveAppend

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

Description copied from interface: GraphBuilderContext

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

Specified by:

recursiveAppend in interface GraphBuilderContext

Parameters:

value - the node to be added to the graph

Returns:

either the node added or an equivalent node

push

public void push(Kind 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.getKind() 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 void 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

intrinsify

public void intrinsify(ResolvedJavaMethod targetMethod,
                       ResolvedJavaMethod substitute,
                       ValueNode[] args)

Description copied from interface: GraphBuilderContext

Intrinsifies an invocation of a given method by inlining the bytecodes of a given substitution method.

Specified by:

intrinsify in interface GraphBuilderContext

Parameters:

targetMethod - the method being intrinsified

substitute - the intrinsic implementation

args - the arguments with which to inline the invocation

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
