Question
You have the following code fragment.
LOOP: LD R1, 0(R2) ;load R1 from address 0+(R2)
DADDI R1, R1, #1 ;R1 <– R1 + 1
SD R1, 0, (R2) ;store (R1) at address 0(R2)
DADDI R2, R2, #4 ;R2 <– R2 + 4
DSUB R4, R3, R2 ;R4 <– R3 - R2
BNEZ R4, LOOP ;branch to LOOP if (R4) != 0
Assume that the initial value of R3 is (R2)+20.
