--- 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 return
the value in %eax, while the above computes something into %ebx and overwrites
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
