Class CompositeValue

java.lang.Object

Value

org.graalvm.compiler.lir.CompositeValue

Direct Known Subclasses:

AArch64AddressValue, AMD64AddressValue

public abstract class CompositeValue
extends Value

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

visitEachComponent

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

toString

public String toString()

hashCode

public int hashCode()

equals

public boolean equals(Object obj)
