Exercise 2: Write a function without branches Consider the discrete-valued function f defined on integers in the set -3, -2,-1, 0, 1, 2, 3). Here's the function definition f (-3) -6 f (-2)-61 f(-1) = 17 f(0) =-38 f (1) - 19 f (2)42 Your task is to implement it in RISC-V, with the condition that your code may NOT use any branch instructions! You can use the file "discrete fn.s" for this exercise. Notice that there is an array of integers in the .data section of "discrete_fn.s" How can you use this to your advantage and complete this task?
