short arith3 (short x, short y, short z) { } short p1. short p2 short p3 = short p4 = return p4; The portion of the generated assembly code implementing these expressions is as follows: short arith3 (short x, short y, short z) x in %rdi, y in %rsi, z in %rdx arith3: orq %rsi,%rdx sarq $9, %rdx notq %rdx movq %rdx, %bax subq %rsi, %rbx ret Based on this assembly code, fill in the missing portions of the C code.
