It was already the case.

Thanks!

Apparenlty GNU as do not like the addil line below:

        addil   lt'overflow,%r19,%r1
        add     %arg0,%arg1,%ret0
        ldw     rt'overflow(%r1),%r20
        addc    0,0,%r22
        stw     %r22,0(%r20)

Look like it expext only 2 arguments and get three...
