(tests): Add tstatexit and tstcxaatexit. (module-names): Add modatexit and modcxaatexit. Add rules to build and run tstatexit and tstcxaatexit. * dlfcn/modatexit.c: New file. * dlfcn/modcxaatexit.c: New file. * dlfcn/tstatexit.c: New file. * dlfcn/tstcxaatexit.c: New file. * io/Makefile: Pass -DHAVE_DOT_HIDDEN to stat and mknod functions if .hidden is available. * io/stat.c: If .hidden is available use it to avoid exporting functions. * io/fstat.c: Likewise. * io/lstat.c: Likewise. * io/stat64.c: Likewise. * io/fstat64.c: Likewise. * io/lstat64.c: Likewise. * sysdeps/generic/mknod.c: Likewise. * malloc/mtrace.c: Use __cxa_atexit and not atexit. * sysdeps/generic/bb_init_func.c: Likewise. * sysdeps/generic/libc-start.c: Likewise. * stdlib/atexit.c (__new_exitfn): Move to cxa_atexit.c. (atexit): Implement using __cxa_atexit. Use .hidden if availble to avoid exporting atexit. * stdlib/cxa_atexit.c (__new_exitfn): Moved to here from atexit.c. * stdlib/Versions: Export __new_exitfn for GLIBC_2.2.3. * stdlib/Makefile (routines): Add old_atexit. (static-only-routines): Add atexit. Pass -DHAVE_DOT_HIDDEN for atexit.c if .hidden is available. * stdlib/old_atexit.c: New file. * intl/Makefile: Remove bogus endif. --- dlfcn/modatexit.c | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 dlfcn/modatexit.c (limited to 'dlfcn/modatexit.c') diff --git a/dlfcn/modatexit.c b/dlfcn/modatexit.c new file mode 100644 index 0000000000..110feadad8 --- /dev/null +++ b/dlfcn/modatexit.c @@ -0,0 +1,41 @@ +/* Copyright (C) 2001 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 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.
