(15 points) Translate the following C code into MIPS assembly language. If you need to use registers $t0 through $t9 or $s0 through $s7, use the lower-numbered registers first.

Completed the assembly language program, submit your program as a separated .asm file.

Procedure func is a leaf procedure, and procedure f is a non-leaf procedure.

Assume that the arguments a, b, c, and d for function f are in $a0-$a3, respectively, and the return value is in $v0.

Assume that the arguments a and b for function func are in $a0-$a1, respectively, and the return value is in $v0.

The code for functions main, f and func is as follows:

void main ( ) {

int g = -5;

int h = 10;

int i = 15;

int j = 20

f (g, h, i, j);

}

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

int x = c+d; // x should be 35

int y = func(a, b); // y should be 15

return func(x, y); // return value should be 20

}

int func (int a, int b) {

if (a > b)

return a - b;

else

return b - a;

}
