Question

Complete the ARM Legv8 implementation of Main given C code. Do not implement return 0; in main(). Use Ldur,Stur,Stack if necessary, do not use MOV,LDR. X stored in X19,y in X20,w in X21,z in X22

int main() {

int x, y;

w = Sum(x, y);

z = Dif(y, x);

return 0; // Do not implement

}

LEGv8 code:

Main:
      // Type your code here.


      B End

// Procedure Sum (Do not modify)
Sum:
      ADD X2, X0, X1
      BR X30

// Procedure Dif (Do not modify)
Dif:
      SUB X2, X0, X1
      BR X30

End:
