Problem 6: (17 pts) Part 1: (9 pts) Implement the following C code in RISC-V assembly. Part 2: (3 pts) What is the total number of RISC-V instructions needed to execute the function? int fib (int n) { if (n==0) return 0; else if (n==1) return 1; else return fib(n-1) + fib(n-2); } Part 3: (5 pts) For each function call above, show the contents of the stack after the function call is made. Assume the stack pointer is originally at address 0x7ffffffc, and follow the register convention of RISC-V (argument, saved, temporary, sp, RET, etc etc). Solution: Problem 7: (9 pts) Part 1: (6 pts) Translate function f into RISC-V assembly language. Assume that the function declaration for function g is: int g (int a, int b); The code for function f is as follows: int f(int a, int b, int c, int d) { return g (g(a,b), c+d); } Part 2: (3 pts) Can we determine the contents of registers: x10 x14, x8, x1, and sp? We know what the entire function f looks like, but for function g we only know its declaration. Solution:
