assembly - What's wrong with this code in ARM -

-

i compiled simple program add 2 number , print on console.i have compiled on rpi board.i think compiled fine when run getting segmentation fault.

.text  .global main .extern print  out:    .ascii "the sum %d\n\0"  main:  push {ip,lr}  mov r0,#5  mov r1,#4  add r2,r1,r0   ldr r2,=out      bl printf  pop {ip,pc}  stop: b stop

is because didn't follow arm eabi properly?

could let me know doing wrong?

the format string printf (out) needs go in r0, not r2. change:

ldr r2,=out

to:

ldr r0,=out

also if want print sum of 4 , 5 should in r1 (otherwise you're printing 4). change:

add r2,r1,r0

to:

add r1,r1,r0
