All Implemented Interfaces:

Cloneable, Formattable, FixedNodeInterface, FixedWithNextNodeInterface, MemoryAccess, LIRLowerable, ValueNodeInterface, IntrinsicMethodNodeInterface

Direct Known Subclasses:

ArrayCompareToNode, ArrayEqualsNode, ArrayIndexOfNode, ArrayRegionCompareToNode, ArrayRegionEqualsNode, ArrayRegionEqualsWithMaskNode, CalcStringAttributesNode, CountPositivesNode, VectorizedHashCodeNode, VectorizedMismatchNode

public abstract class PureFunctionStubIntrinsicNode
extends FixedWithNextNode
implements MemoryAccess, IntrinsicMethodNodeInterface

Base class for nodes that represent large intrinsic methods without side effects, such as ArrayEqualsNode. These methods are compiled as stubs and later called via foreign call.

 Stamp stamp,
 EnumSet<?> runtimeCheckedCPUFeatures,
 org.graalvm.word.LocationIdentity locationIdentity)

Method Details

getRuntimeCheckedCPUFeatures

public EnumSet<?> getRuntimeCheckedCPUFeatures()

On SVM, we AOT-compile additional stub versions with more modern CPU flags enabled. We can emit foreign calls to these variants in JIT code when these flags are available.

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

Specified by:

getLocationIdentity in interface MemoryAccess

getLastLocationAccess

public MemoryKill getLastLocationAccess()

Specified by:

getLastLocationAccess in interface MemoryAccess

Returns:

a MemoryKill that represents the last memory state in the memory graph for the LocationIdentity returned by MemoryAccess.getLocationIdentity()

setLastLocationAccess

public void setLastLocationAccess(MemoryKill lla)

Specified by:

setLastLocationAccess in interface MemoryAccess

Parameters:

lla - the MemoryKill that represents the last kill of the LocationIdentity returned by MemoryAccess.getLocationIdentity()
