Consider the following code, in which we have omitted the expression being computed:

short scale3 (short x, short y, short z) { short t = return t; } Compiling the actual function with GCC yields the following assembly code: short scale3 (short x, short y, short z) x in %rdi, y in %rsi, z in %rdx scale3: leaq (%rsi,%rsi, 9), %rbx leaq (%rbx, %rdx), %rbx leaq (%rbx, %rdi, %rsi), %rbx ret Fill in the missing expression in the C code.
