Suppose that we want to add a load-immediate instruction to the instruction set for our 5-stage pipeline. The instruction holds a 16 bit immediate operand value that must be sign-extended and then stored in the destination register. During a design meeting it is proposed that, since sign extension is simple and does not require the ALU, this instruction could perform its register write in the ID stage. Identify all new hazard situations that are introduced into the pipeline as a result of this proposed change and provide a specific example of each. 2
