The user uses the following commands and affects the process’ PCB in the following ways:   The user first runs top, which lists every process and its [q1] read from the pcb, along with its pid and [q2] — which is used by the scheduler to order ready processes. Next, the user runs ps using the pid and inspects the [q3] to read process details, recorded in the process’s PCB. Finally, the user runs kill on the process, which causes a state transition from RUNNING to [q4].

Krishin wants to introduce a new SWAP instruction to the LC-2200 ISA that follows the specification below: Syntax: SWAP Rx, Ry Semantics: Places the contents of Rx into Ry and the contents of Ry into Rx   Krishin realizes that this instruction needs to write to 2 registers in the WB stage, which is a problem because the dual-ported register file of the classic 5-stage LC-2200 pipeline does not support accomplishing this in one clock cycle. He decides to modify the register file to support 2 simultaneous writes to the register file in the same clock cycle. Which of the following hazards does this modification address?
