Problem 2 Add comments to the following ARM code fragment (4 points). Describe in one sentence what it computes (5 points) Assume that rO is used for the input and imitially contains to describe n, a positive integer and rt is used for the output. Use an example your approach to finding the solution (6 points). r0, #0 r1, #1 r2, #0 r3, rl r2, #1 r2, #0 finish begin: Mov MoV MoV loop: CMP MOVLT CMP BNE ADDS ADDS rLrL #2 loop r4, ro finish: Mov
