Assume that i and k correspond to registers x22 and x24.
addi x24,x0,5           //  Let's Just assume for now that k = 5
addi x22,x0,0.          // initialize the value of i to be 0
Loop:                       // assign label
beq x22,x24,Exit.    // if i == k , then go to exit
addi x22,x22,1.       // i = i + 1
beq x0,x0,Loop.      // if x0 == x0 , then go back to the loop (which is always true)
Exit:                        // quit the program
