Question

Translate the following C code to MIPS assembly. The main function and subfunction are translated to two separate .asm files.

Finish the assembly code segment for the above requirement.

int main() {

int x=2; int y=1; int z=0; z=Subfunc(x,y); printf(“Value of z is: %d”, z);

}

int Subfunc(int x, int y)

{ int t1=0;

t1=x+y+100; return t1;} File 1: .data

str: .asciiz "The value of z:"

.text

#.globl main main: addi $s0, $0,2 #x addi $s1, $0,1 #y addi $s2, $0,0 #z

move $a0, $s0 move $a1, $s1 jal subfunc

move $s2, $v0 # updated from $s0

la $a0, str li $v0, 4 syscall

move $a0, $s2 #print result, # updated from $s0

li $v0, 1

syscall

li $v0, 10 #exit

syscall

File 2：

.text

.globl subfunc

subfunc:
