                                   FixedWithNextNode lastInstr,
                                   boolean unwindExceptions)

                                   FixedWithNextNode lastInstr)

PEAppendGraphBuilderContext

Method Detail

isParsingInvocationPlugin

public boolean isParsingInvocationPlugin()

Specified by:

isParsingInvocationPlugin in interface GraphBuilderContext

Overrides:

isParsingInvocationPlugin in class PEGraphDecoder.PENonAppendGraphBuilderContext

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

Overrides:

push in class PEGraphDecoder.PENonAppendGraphBuilderContext

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.

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

Overrides:

setStateAfter in class PEGraphDecoder.PENonAppendGraphBuilderContext

Parameters:

stateSplit - a side effect node just appended to the graph

append

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

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

Overrides:

append in class PEGraphDecoder.PENonAppendGraphBuilderContext

Parameters:

v - the node to be added to the graph

Returns:

either the node added or an equivalent node

getInvokeKind

public CallTargetNode.InvokeKind getInvokeKind()

Description copied from interface: GraphBuilderContext

Gets the kind of invocation currently being parsed.

Specified by:

getInvokeKind in interface GraphBuilderContext

Overrides:

getInvokeKind in class PEGraphDecoder.PENonAppendGraphBuilderContext

getInvokeReturnType

public JavaType getInvokeReturnType()

Description copied from interface: GraphBuilderContext

Gets the return type of the invocation currently being parsed.

Specified by:

getInvokeReturnType in interface GraphBuilderContext

Overrides:

getInvokeReturnType in class PEGraphDecoder.PENonAppendGraphBuilderContext

handleReplacedInvoke

public void handleReplacedInvoke(CallTargetNode callTarget,
                                 JavaKind resultType)

Specified by:

handleReplacedInvoke in interface GraphBuilderContext

Overrides:

handleReplacedInvoke in class PEGraphDecoder.PENonAppendGraphBuilderContext

genExplicitExceptionEdge

public AbstractBeginNode genExplicitExceptionEdge(BytecodeExceptionNode.BytecodeExceptionKind exceptionKind,
                                                  ValueNode... exceptionArguments)

Description copied from interface: GraphBuilderContext

Generates an exception edge for the current bytecode. When GraphBuilderContext.needsExplicitException() returns true, this method should return non-null begin nodes.

Parameters:

exceptionKind - the type of exception to be created.

exceptionArguments - the arguments for the exception.

Returns:

a begin node that precedes the actual exception instantiation code.

getNonIntrinsicAncestor

public GraphBuilderContext getNonIntrinsicAncestor()

Description copied from interface: GraphBuilderContext

Gets the first ancestor parsing context that is not parsing a intrinsic.
