Question $3$

Which of the expressions is equivalent to the following instruction sequence?

$slt$ $$t2,$$$t0,$$$t1$

beq $$t2,$$zero,$L1$

sub $$t3,$$$t1,-$$$t0$

$j$ End

$L1$: sub $$t3,$$$t0,-$$$t1$

End:

O

$if($$$t0$$$t1)$

$$t3=$$$t1-$$$t0$

else

$$t1=$$$t0-$$$t1$

$if($$$t0$$$t1)$

$$t1=$$$t0-$$$t1$

else

$$t3=$$$t1-$$$t0$

J

$if($$$t0>$$$t1)$

$$t3=$$$t1-$$$t0$

else

$$t1=$$$t0-$$$t1$

$if($$$t0>$$$t1)$

$$t1=$$$t0-$$$t1$

else

$$t3=$$$t1-$$$t0$
