1. (10 bonus points) [Exercise 2.34 with minor change] Translate functions f and func into Mars MIPS assembly language. If you need to use registers $t0 through $t9 or $s0 through $s7, use the lower-numbered registers first. The code for functions func and f is as follows:

int func (int a, int b) {

if (a b)

return a;

else

return b;

}

int f (int a, int b, int c, int d) {

return func(func(a,b),c+d);

}

• Function func is a leaf procedure, and function f is a non-leaf procedure.
• Assume that the arguments a, b, c, and d are in $a0-$a3, respectively, and the return value is in $v0.
