I'm having trouble with my Computer Operation assignment.

1. What is the Zero register used for in the ARMv8 architecture?

2. Can you implement the following code (shown below) in ARMv8 assembly, without using branching? How? Show your code

if (i == 0) r = r + 2;

else r = r - 1;

3. Implement the following code (shown below) in ARMv8 assembly down below. Show your code

z = a * (b+c)

4. How can you implement the following c-code for loop in ARMv8 assembly? Show your code

for (k = 0; k < 5; k++)

{ m = m + m;

}
