MacroWithExceptionNode

                                 MacroNode.MacroParams p)

Method Detail

inferStamp

public boolean inferStamp()

Description copied from class: ValueNode

This method can be overridden by subclasses of ValueNode if they need to recompute their stamp if their inputs change. A typical implementation will compute the stamp and pass it to ValueNode.updateStamp(Stamp), whose return value can be used as the result of this method.

Overrides:

inferStamp in class ValueNode

Returns:

true if the stamp has changed, false otherwise.

verifyStamp

protected void verifyStamp()

getContextMethod

public ResolvedJavaMethod getContextMethod()

Description copied from interface: Invokable

Returns the method from which the call is executed.

Specified by:

getContextMethod in interface Invokable

Returns:

the method from which the call is executed.

getArguments

public NodeInputList<ValueNode> getArguments()

Description copied from interface: MacroInvokable

Gets the arguments for this macro node.

Specified by:

getArguments in interface MacroInvokable

bci

public int bci()

Specified by:

bci in interface DeoptBciSupplier

Returns:

the byte code index (BCI) associated with the node implementing this interface

getTargetMethod

public ResolvedJavaMethod getTargetMethod()

Specified by:

getTargetMethod in interface Invokable

getInvokeKind

public CallTargetNode.InvokeKind getInvokeKind()

Specified by:

getInvokeKind in interface MacroInvokable

afterClone

protected void afterClone(Node other)

Overrides:

afterClone in class Node

replaceWithInvoke

public Invoke replaceWithInvoke()

Description copied from interface: MacroInvokable

Replaces this node with an invoke of the target method.

Specified by:

replaceWithInvoke in interface MacroInvokable

Returns:

the newly create Invoke

createInvoke

public InvokeWithExceptionNode createInvoke(Node oldResult)

Creates an invoke for the MacroWithExceptionNode.getTargetMethod() associated with this node. The exception edge of the result is not set by this function. This node is not modified.

Parameters:

oldResult - represents the result of this node in the MacroWithExceptionNode.stateAfter(). Usually, it is this, but if this node has already been replaced it might be a different one.

stateAfter

public FrameState stateAfter()

Description copied from interface: StateSplit

Gets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

stateAfter in interface StateSplit

setStateAfter

public void setStateAfter(FrameState x)

Description copied from interface: StateSplit

Sets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

setStateAfter in interface StateSplit

hasSideEffect

public final boolean hasSideEffect()

Description copied from interface: StateSplit

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.

Specified by:

hasSideEffect in interface StateSplit

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

This method is used to determine which memory location is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentity in interface SingleMemoryKill

Returns:

the identity of the location killed by this node.
