Create an ARMv8 A64 assembly language program that finds the maximum of y=-2x - 22x + 11x + 57 in the range -10 x4, by stepping through the range one by one in a loop and testing. Use only long integers for x, and do not factor the expression. Use the printf() function to display to the screen the values of x, y and the current maximum on each iteration of your loop. You are to create 2 versions of your program: 1. Write the program without macros (i.e. don't use m4), and use only the mul, add, and mov instructions to do your calculations. Use a pre-test loop, where the test is at the top of the loop. 2. Optimize the above program by putting the loop test at the bottom of the loop (make sure it is still a pre-test loop), and by making use of the madd instruction. Also, add macros to the above program to make it more readable (use m4). In particular, provide macros for heavily used registers.
