From 1100f84983f22e570a5081cbe79b0ef8fe4952d7 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 10 Oct 2006 00:51:29 +0000 Subject: Jakub Jelinek Implement reference counting of scope records. * elf/dl-close.c (_dl_close): Remove all scopes from removed objects from the list in objects which remain. Always allocate new scope record. * elf/dl-open.c (dl_open_worker): When growing array for scopes, don't resize, allocate a new one. * elf/dl-runtime.c: Update reference counters before using a scope array. * elf/dl-sym.c: Likewise. * elf/dl-libc.c: Adjust for l_scope name change. * elf/dl-load.c: Likewise. * elf/dl-object.c: Likewise. * elf/rtld.c: Likewise. * include/link.h: Inlcude . Define struct r_scoperec. Replace r_scope with pointer to r_scoperec structure. Add l_scoperec_lock. * sysdeps/generic/ldsodefs.h: Include . * sysdeps/generic/rtld-lowlevel.h: New file. * include/atomic.h: Rename atomic_and to atomic_and_val and atomic_or to atomic_or_val. Define new macros atomic_and and atomic_or which do not return values. * sysdeps/x86_64/bits/atomic.h: Define atomic_and and atomic_or. Various cleanups. * sysdeps/i386/i486/bits/atomic.h: Likewise. --- elf/dl-libc.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'elf/dl-libc.c') diff --git a/elf/dl-libc.c b/elf/dl-libc.c index 1b995eda92..8b78a7a388 100644 --- a/elf/dl-libc.c +++ b/elf/dl-libc.c @@ -1,5 +1,5 @@ /* Handle loading and unloading shared objects for internal libc purposes. - Copyright (C) 1999,2000,2001,2002,2004,2005 Free Software Foundation, Inc. + Copyright (C) 1999-2002,2004,2005,2006 Free Software Foundation, Inc.
