For this problem, suppose that the add (addition) and imul (signed multiplication) instructions are broken on one of the lab computers. Write x86-64 assembly code to implement the following C function without add or imul by using leaq (and any other arithmetic) instructions. long arithmewho (long a, long b, long c) { return a + 13 + 9*b + 4*c; } • Respect the calling conventions and register-save conventions. • Do not use any version of the add or imul instructions. You can use any other x86 arithmetic instructions, including leaq. Aim to have 4-6 lines of assembly code.
