Assume the five integer variables a, b, c, i and F are stored in registers X13, X14, X15, X12 and X20, respectively. Write an ARM v8 assembly program that will implement the following code segment. Do not use explicit multiplication instructions: for (i=2; i>b; i=i+4) { if (al=b) F=63'a+c; else if (b!=c) F=a+64*b; else F = a+b+c; }
