On a sufficiently slow computer (CPU speed ~1Hz) this should take around 75 seconds to run:
.globl main
main:
movl $52, %edx
movl $0, %edi
l4:
addl $1, %edi
cmp %edx, %edi
jl l4
call putchar
movl $50, %edx
movl $0, %edi
l2:
addl $1, %edi
cmp %edx, %edi
jl l2
call putchar
movl $10, %edx
movl $0, %edi
ln:
addl $1, %edi
cmp %edx, %edi
jl ln
call putchar
