          extended by org.jikesrvm.compilers.opt.ir.operand.CodeConstantOperand

public final class CodeConstantOperand
extends ConstantOperand

Represents a constant code operand, found for example, from an TIBConstantOperand.

NB we don't use an object constant operand because

  1. code doesn't form part of the object literals
  2. we need to support replacement
