Writing a loop for the sparc machine

Question

I am trying to write the following code for the sparc machine.

y=(x-7)(x-11) for the range 0<=x<=10

and I want to print out the following code like this for input of x=0 output y=77 and so on up to ten.

I managed to make the loop. But my problem is getting the output printed out.

       /*
     This program will compute y=(x-7)(x-11)
     for the range 0<=x<=10
    */

     /*
    these are the variables
    */

.section ".data"

mystring:.asciz "for input of x=%d and output y=%d"

  define(a1,7)

 define(a2,11)

define(x_r,l0)
define(x_r,l1)
.section ".text"

main:
save %sp,-96,%sp
clr %x_r

loop:
 sub %x_r,a1,%o0 !(x-a1)

sub %x_r,a2,%o1 !(x-a2)
call .mul
 nop

  mov %o0,%y_r
  add %x_r,1,%x_r

  cmp %x_r,10
 ble loop
  nop

 ret
 restore

I know I have to print something like this on my code but Im not sure where.

 set mystring,%o0
 move %x_r,%o1
 move %y_r,%o2
 call printf
 nop

THe output I get now is

for input of x=0 output y=77 for input of x=1 output y=60 for input of x=2 output y=45 for input of x=3 output y=32 for input of x=4 output y=21 for input of x=5 output y=12 for input of x=6 output y=5 for input of x=7 output y=0 for input of x=8 output y=-3 for input of x=9 output y=-4 for input of x=10 output y=-3

I would like it like this

for input of x=0 output y=77 for input x=1 output y=60 ...... ...... for input x=10 y=-3

Answer 1

It's been a while since I saw SPARC assembly last time. Nowadays CPUs are either x86 or ARM. My knowledge about SPARC assembly is quite rusty...

1. The second alias is a typo, isn't it? I guess it was meant for y_r

   define(x_r,l0)
   define(x_r,l1)
   

2. With mov %o0,%y_r you store the result of multiplication into %y_r. Whereas the next line add %x_r,1,%x_r is ++x in C. So printf should be invoked between these two.
