Consider the following function in C. unsigned int function (unsigned int a, unsigned int b){ #a is in $a0, b is in $al do { if (b> a) b = b a; if (a > b) a = a - b; } while (a != b); return a; 1. Write the corresponding minimum program using MIPS ISA. You can use regular assembly lan- guage pseudo-instructions in your solution if you wish. Please provide comments to help the grader understand your code. (18) 2. What is this function doing? Provide your guess. (3)
