From adc12574e555ec7d6ba3969eed4f829705c235ab Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 31 Jul 2003 07:42:20 +0000 Subject: Update. 2003-07-30 Jakub Jelinek * 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. --- nptl/tst-tls4moda.c | 56 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 nptl/tst-tls4moda.c (limited to 'nptl/tst-tls4moda.c') diff --git a/nptl/tst-tls4moda.c b/nptl/tst-tls4moda.c new file mode 100644 index 0000000000..ff7ee56042 --- /dev/null +++ b/nptl/tst-tls4moda.c @@ -0,0 +1,56 @@ +/* Copyright (C) 2003 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Jakub Jelinek , 2003. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
