Modifier and Type	Method and Description
void	addUsedVariables(List<Variable> l) Append the list of variables used in this operand to the input list -- force every operand to implement this because a missing implementation can cause bad failures.
boolean	canCopyPropagate() Can we replace every use of a variable 'v' that contains the value of this operand with the operand itself? This takes importance when there are at least two uses of 'v' within this scope.

Method Detail

getOperandType

public OperandType getOperandType()

Specified by:

getOperandType in class Operand

addUsedVariables

public void addUsedVariables(List<Variable> l)

Description copied from class: Operand

Append the list of variables used in this operand to the input list -- force every operand to implement this because a missing implementation can cause bad failures.

Specified by:

addUsedVariables in class Operand

getSelf

public Variable getSelf()

getClosure

public IRClosure getClosure()

canCopyPropagate

public boolean canCopyPropagate()

Description copied from class: Operand

Can we replace every use of a variable 'v' that contains the value of this operand with the operand itself? This takes importance when there are at least two uses of 'v' within this scope. Ex: v = [1,2,3]; x = v; y = v In this case, we cannot replace the occurences of 'v' because we would then get x = [1,2,3]; y = [1,2,3] which would then result in two different array objects being constructed instead of a single one.

Overrides:

canCopyPropagate in class Operand

Returns:

true if it is safe to copy-propagate the operand.

toString

public String toString()

Overrides:

toString in class Object

getSimplifiedOperand

public Operand getSimplifiedOperand(Map<Operand,Operand> valueMap,
                           boolean force)

Overrides:

getSimplifiedOperand in class Operand

cloneForInlining

public Operand cloneForInlining(CloneInfo info)

Specified by:

cloneForInlining in class Operand

retrieve

public Object retrieve(ThreadContext context,
              IRubyObject self,
              StaticScope currScope,
              DynamicScope currDynScope,
              Object[] temp)

Overrides:

retrieve in class Operand

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Operand

decode

public static WrappedIRClosure decode(IRReaderDecoder d)

visit

public void visit(IRVisitor visitor)
