2003-07-30 Jakub Jelinek <jakub@redhat.com> * elf/dl-reloc.c (_dl_allocate_static_tls): Don't return any value, call dl_signal_error directly. If already relocated, call GL(dl_init_static_tls) directly, otherwise queue it for later. (CHECK_STATIC_TLS): Undo 2003-07-24 change. * elf/rtld.c (dl_main): Initialize GL(dl_init_static_tls). * elf/dl-open.c (dl_open_worker): Call GL_dl_init_static_tls for all static TLS initializations delayed in _dl_allocate_static_tls. * elf/dl-support.c (_dl_init_static_tls): New variable. * include/link.h (struct link_map): Add l_need_tls_init. * sysdeps/generic/ldsodefs.h (_rtld_global): Add _dl_init_static_tls. (_dl_nothread_init_static_tls): New prototype. (_dl_allocate_static_tls): Adjust prototype. * elf/tls-macros.h (VAR_INT_DEF): Add alignment directive. elf_machine_rela_relative): Adjust. (CHECK_STATIC_TLS): _dl_allocate_static_tls can fail now.
