--- Comment #25 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Ah, sorry, my fault apparently.
        pushl   %ebx
        movl    %gs:0, %ebx
        addl    $s@ntpoff, %ebx
        popl    %ebx
        ret
of course doesn't make sense, because when it is a function, it should retu=
rn
the value in %eax, while the above computes something into %ebx and overwri=
tes
it and then just returns an uninitialized reg.
So we need:
        pushl   %ebx
        movl    %gs:0, %ebx
        addl    $s@ntpoff, %ebx
        movl    %ebx, %eax
        popl    %ebx
        ret=
