Class CompositeValue

java.lang.Object

jdk.internal.jvmci.meta.AbstractValue

com.oracle.graal.lir.CompositeValue

All Implemented Interfaces:

KindProvider, TrustedInterface, Value

Direct Known Subclasses:

AMD64AddressValue, CompositeValueReplacementTest1.TestCompositeValue, SPARCAddressValue

public abstract class CompositeValue
extends AbstractValue

Base class to represent values that need to be stored in more than one register. This is mainly intended to support addresses and not general arbitrary nesting of composite values. Because of the possibility of sharing of CompositeValues they should be immutable.

Method Detail

forEachComponent

public abstract CompositeValue forEachComponent(LIRInstruction inst,
                                                LIRInstruction.OperandMode mode,
                                                InstructionValueProcedure proc)

Invoke proc on each Value element of this CompositeValue. If proc replaces any value then a new CompositeValue should be returned.

Parameters:

inst -

mode -

proc -

Returns:

the original CompositeValue or a copy with any modified values

visitValueArray

protected Value[] visitValueArray(LIRInstruction inst,
                                  Value[] values,
                                  LIRInstruction.OperandMode mode,
                                  InstructionValueProcedure proc,
                                  EnumSet<LIRInstruction.OperandFlag> flags)

A helper method to visit Value[] ensuring that a copy of the array is made if it's needed.

Parameters:

inst -

values -

mode -

proc -

flags -

Returns:

the original values array or a copy if values changed

forEachComponent

protected abstract void forEachComponent(LIRInstruction inst,
                                         LIRInstruction.OperandMode mode,
                                         InstructionValueConsumer proc)

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractValue

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractValue
