c$.(10$ points$)$ Consider another processor which has a stuck$-$at$-1$ fault on the Read register $1$s bit $0$ signal. Is

the processor still usable? To be usable, we must be able to convert any program that executes on a normal

MIPS processor into a program that works on this processor. You can assume that there is enough free

instruction memory and data memory to let you make the program longer and store additional data. Hint:

the processor is usable if every instruction $$broken$$ by this fault can be replaced with a sequence of

$$working$$ instructions that achieve the same effect.
