From 5f21997b9d6a49ddbed85b044e2be7b182c095a2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 18 Oct 2004 23:17:46 +0000 Subject: Update. 2004-10-18 Jakub Jelinek * elf/dl-libc.c (__libc_dlsym_private, __libc_register_dl_open_hook): New functions. (__libc_dlopen_mode): Call __libc_register_dl_open_hook and __libc_register_dlfcn_hook. * dlfcn/Makefile (routines, elide-routines.os): Set. Add rules to build and test tststatic2. * dlfcn/tststatic2.c: New test. * dlfcn/modstatic2.c: New test module. * dlfcn/dladdr.c: Call _dlfcn_hook from libdl.so if not NULL. Define __ prefixed routine in libc.a and in libdl.a just call it. * dlfcn/dladdr1.c: Likewise. * dlfcn/dlclose.c: Likewise. * dlfcn/dlerror.c: Likewise. * dlfcn/dlinfo.c: Likewise. * dlfcn/dlmopen.c: Likewise. * dlfcn/dlopen.c: Likewise. * dlfcn/dlopenold.c: Likewise. * dlfcn/dlsym.c: Likewise. * dlfcn/dlvsym.c: Likewise. * dlfcn/sdladdr.c: New file. * dlfcn/sdladdr1.c: New file. * dlfcn/sdlclose.c: New file. * dlfcn/sdlerror.c: New file. * dlfcn/sdlinfo.c: New file. * dlfcn/sdlopen.c: New file. * dlfcn/sdlsym.c: New file. * dlfcn/sdlvsym.c: New file. * dlfcn/Versions (libdl): Export _dlfcn_hook@GLIBC_PRIVATE. * include/dlfcn.h (DL_CALLER_DECL, DL_CALLER RETURN_ADDRESS): Define. (struct dlfcn_hook): New type. (_dlfcn_hook): New extern decl. (__dlopen, __dlclose, __dlsym, __dlerror, __dladdr, __dladdr1, __dlinfo, __dlmopen, __libc_dlsym_private, __libc_register_dl_open_hook, __libc_register_dlfcn_hook): New prototypes. (__dlvsym): Use DL_CALLER_DECL. * include/libc-symbols.h: Define libdl_hidden_proto and friends. * malloc/arena.c (_dl_open_hook): Extern decl. (ptmalloc_init): Don't call _dl_addr when dlopened from statically linked programs but don't use brk for them either. --- dlfcn/dladdr.c | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) (limited to 'dlfcn/dladdr.c') diff --git a/dlfcn/dladdr.c b/dlfcn/dladdr.c index b5490e5a8d..d0462b94ff 100644 --- a/dlfcn/dladdr.c +++ b/dlfcn/dladdr.c @@ -1,5 +1,6 @@ /* Locate the shared object symbol nearest a given address. - Copyright (C) 1996, 1997, 1998, 1999, 2003 Free Software Foundation, Inc. + Copyright (C) 1996, 1997, 1998, 1999, 2003, 2004 + Free Software Foundation, Inc.
