Method Summary

Modifier and TypeMethod and Description
public void
addUsedVariables(List<Variable> l)

Implements abstract org.jruby.ir.operands.Operand.addUsedVariables.

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.

public boolean
canCopyPropagate()

Overrides org.jruby.ir.operands.Operand.canCopyPropagate.

Can we replace every use of a variable 'v' that contains the value of this operand with the operand itself?

public Operand
cloneForInlining(CloneInfo ii)

Implements abstract org.jruby.ir.operands.Operand.cloneForInlining.

Returns a string representation of the object.

canCopyPropagateback to summary
public boolean canCopyPropagate()

Overrides org.jruby.ir.operands.Operand.canCopyPropagate.

Doc from org.jruby.ir.operands.Operand.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. Ex: v = [1,2,3]; x = v; y = v In this case, we cannot replace the occurrences 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.

Returns:boolean

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