From be93561004695198611aa8707f10250f780988b2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 6 Sep 1998 09:16:53 +0000 Subject: Update. 1998-09-06 09:00 Ulrich Drepper * version.h (VERSION): Bump to 2.0.96. Rewrite runtime linker to be truly thread-safe. There is now no global variable specifying the scope. We create all needed scopes at the time the link maps are created. * elf/Versions [GLIBC_2.1]: Add _dl_loaded and _dl_main_searchlist. * elf/link.h: Add struct r_scope_elem and use this for l_searchlist, l_symbolic_searchlist, l_scope, and l_local_scope elements in struct link_map. * elf/dl-close.c: Rewritten accordingly. * elf/dl-deps.c: Likewise. * elf/dl-error.c: Likewise. * elf/dl-init.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-lookup.c: Likewise. * elf/dl-object.c: Likewise. * elf/dl-open.c: Likewise. * elf/dl-reloc.c: Likewise. * elf/dl-runtime.c: Likewise. * elf/dl-support.c: Likewise. * elf/dl-symbol.c: Likewise. * elf/dl-version.c: Likewise. * elf/dlfcn.h: Likewise. * elf/dlsym.c: Likewise. * elf/dlvsym.c: Likewise. * elf/ldsodefs.h: Likewise. * elf/rtld.c: Likewise. * iconv/gconv_dl.c: Likewise. * nss/nsswitch.c: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/unix/sysv/linux/i386/dl-librecon.h: Likewise. --- elf/dl-support.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'elf/dl-support.c') diff --git a/elf/dl-support.c b/elf/dl-support.c index 9b94907940..76af1883ac 100644 --- a/elf/dl-support.c +++ b/elf/dl-support.c @@ -66,6 +66,20 @@ void *__libc_stack_end; /* Path where the binary is found. */ const char *_dl_origin_path; +/* Initially empty list of loaded objects. */ +struct link_map *_dl_loaded; + +/* Fake scope.
