Attempt to execute non instruction

Question

This is a mips assembly code for a C code.I am simulating it using Qtspim, but I am getting an error as titled above.

    .text

# j=$s0 , i=$t0 

main:
        li $s0,5 # setting j to 5 
        li $t0,0 # setting i to zero


loop:
        slti $t1,$t0,8
        bne $t1,1,Exit
        add $s0,$s0,$t0
        addi $t0,$t0,1
        beq $s0,10,Exit
        j loop


Exit:       

The C code which I am trying to convert into assembly is as below

  j=5;

for(t=0,i<8;i++){

    j=j+1;
    if(j==10)
        return;
}

Answer 1

If you are having problems with "attempt to execute non istruction at address 0x..." try adding at the end of your code this :

li $v0,10
syscall

the pc counter will always add +4 to the pc (because instructions are stored in multiplies of 4) and it will do this until you won't say EXIT FROM PROGRAM.

Yes ,the procedure of terminating the program is fault of the programmer,so you will write a exit syscall in order to terminate your code.

For who did some code in 8086 can remember that there was a .EXIT routine that return the control of the program to the DOS, so it's the same as syscall
