PROBLEM 1 (20 POINTS) A. A (10 points) Write the ARMv8 assembly function that receives the values of a and b (positive and integer values) in registers X0 and X1 respectively and returns the y. You need to keep the conventions. What does this function do and write it in assembly Legv8?

y = f(a, b) = ( a if b = 0)

(a + (f(a + 1, b ? 1))) else B.

B (10 points) For your program, draw the map of the stack at its peak for f(5, 2).
