"local label 1, backwards" ie the first label "1" you'll
meet when going back up. Opposite is "1f" (Forward) which
means "the first label you'll meet going forward in the
1: cmp r0,#0
If r0==0, you leave the loop, otherwise you stay in it
(obviously that's not what you'd do in real life, you'd call
your labels "1", "2", ...)
