Update.
2002-02-06 Ulrich Drepper <drepper@redhat.com> * Versions.def [ld]: Add GLIBC_2.3. * elf/Versions [ld]: Add __tls_get_addr to GLIBC_2.3. * elf/Makefile (dl-routines): Add dl-tls. (distribute): Add dl-tls.h. * sysdeps/generic/ldsodefs.h (struct rtld_global): Remove _dl_tls_module_cnt, add _dl_tls_max_dtv_idx and _dl_tls_dtv_gaps. Add prototypes for _dl_next_tls_modid and _dl_determine_tlsoffset. * elf/dl-load.c (_dl_map_object_from_fd): Store alignment requirement along with the other info in the link map. Change queueing of init images for double linked list. Use _dl_next_tls_modid to compute l_tls_modid. * elf/rtld.c (_dl_start_final): Store alignment requirement along with the other info in rtld map and executable map. (dl_main): Add ld.so to the init image list if necessary. Compute final module ID with _dl_next_tls_modid. * include/link.h (struct link_map): Add l_tls_previmage and l_tls_align. * eld/dl-support.c: Define _dl_tls_max_dtv_idx and _dl_tls_dtv_gaps. * sysdeps/i386/elf/Versions: New file. * sysdeps/generic/dl-tls.c: New file. * sysdeps/generic/dl-tls.h: New file. * sysdeps/i386/dl-tls.h: New file. attribute((packed)) to counter stupid people misusing gcc options.
