org.jikesrvm.compilers.opt.ir.operand
Class TrueGuardOperand

java.lang.Object
  org.jikesrvm.compilers.opt.ir.operand.Operand
      org.jikesrvm.compilers.opt.ir.operand.ConstantOperand
          org.jikesrvm.compilers.opt.ir.operand.TrueGuardOperand

public final class TrueGuardOperand
extends ConstantOperand
extends ConstantOperand

This operand represents a "true" guard. Eg non-nullness of the result of an allocation or boundcheck eliminate via analysis of the loop induction variables.
