The Jasmin code is clearly suboptimal for both speed and size. Write an equivalent but more optimized Jasmin code sequence .

Consider the following function Foo in Pascal program named FinalFor. Assume that Bar is a
procedure that has already been defined.
FUNCTION Foo(first, last : integer) : integer;
VAR
i : integer;
BEGIN
FOR i := first TO last DO Bar(i);
Foo := i
END;
The Pascal compiler generates the following Jasmin code:
.method private static foo(II)I
. var 0 is first I
. var 2 is i I
. var 1 is last I
. var 3 is foo I
iload_0
istore_2
LØ01:

Prob 7. We have learned in the class that using the barrel shifter, we can implement multiplication/division of a number for some special cases with addition, subtraction, and reversed subtraction instructions as well as shift instructions. For each of the following calculations, write a single-line assembly code to perform it using this approach assuming signed integers A and B are saved in r0 and ri respectively: (a) A = 7 * B / 8 (b) A 7 B/8 5
