--- Comment #20 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note, for ntpoff the listed instructions are: movl %gs:0,%eax leal x@ntpoff(%eax),%eax rather than addl. But certainly this one was never meant to be taken pedantically as that instruction sequence only, it is completely intentional that the %gs:0 load can be far away (used by multiple TLS LE or IE accesses), and even tls.pdf mentions some other instructions: movl %gs:0,%eax movl x@ntpoff(%eax),%eax and movl %gs:x@ntpoff,%eax are all mentioned.
