Long decode2 (long x, long y, long z); GCC generates the following assembly code: decode2: subq Degree %rdx, Degree %rsi imulq Degree %rsi, Degree %rdi movq %rsi, %rax salq $63, Degree %rax sarq $63, Degree %rax xorq %rdi, %rax ret Parameters x, y, and z are passed in registers %rdi, %rsi, and %rdx. The code stores the return value in register %rax. Write C code for decode2 that will have an effect equivalent to the assembly code shown
