3. Write MIPS code to implement a leaf procedure for the following C function: int leaf_procedure (int x, int y) { } int i, a; a=x+y; a=a+i; return a; Assume that the variables x and y are passed from argument registers $a0 and $al respectively. The returned value should be stored in register $v0. Note that you need to use stack to store any other registers if you use them in this procedure.
