Question 2: Stack and subroutines

• Solve this question by writing subroutines which get parameters and return value via the stack!
• Explain the purpose of each instruction!

1. Write a 32-bits addition subroutine that gets two operands from the stack and returns the sum. Each operand must be a 32-bits integer.
2. A recursive subroutine that computes fib(n) = fib(n-1)+fib(n-2), fib(0) = 0, fib(1) = 1
