Q3. If we change load/store instructions to use a register (without an offset) as the address, then those instructions no longer require the use of an ALU. As a result, we can consolidate EX and MEM into a single stage resulting in a 4-stage pipeline. Assume the cycle time does not change. (a) Give an example of code where we will lose performance due to this change (may have to show code for
