From 4d6acc61fa6892b40eaf94de4ff506ff83e37490 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 13 Jun 1996 04:06:45 +0000 Subject: Thu Jun 13 00:02:25 1996 Roland McGrath * elf/dl-lookup.c (_dl_lookup_symbol): If no value and *REF is null, consider it a strong reference and give the error. Wed Jun 12 15:52:46 1996 Roland McGrath * elf/dl-open.c (_dl_open): Correctly terminate relocating loop after relocating NEW when it's the only new object. * elf/dl-init.c (_dl_init_next): When out of initializers, set _r_debug.r_state to RT_CONSISTENT and call _dl_debug_state just before return. * elf/rtld.c (dl_main): Move _dl_debug_initialize call after relocation. Call it unconditionally and only fill in DT_DEBUG if it's present. Then call _dl_debug_state with r_state RT_ADD before running initializers. * elf/dl-open.c (_dl_open): Call _dl_debug_initialize and then call _dl_debug_state with r_state RT_ADD before running initializers * elf/dl-close.c (_dl_close): Call _dl_debug_state with r_state RT_DELETE before running finalizers and with RT_CONSISTENT just before return. * elf/Makefile (dl-routines): Add dl-debug. * elf/dl-debug.c: New file. * elf/rtld.c (_dl_r_debug): Rename to _r_debug and move to dl-debug.c. (_dl_r_debug_state): Rename to _dl_debug_state and likewise move. (dl_main): Use _dl_debug_initialize. * elf/link.h: Fix name to _dl_debug_state in decl. (_dl_debug_initialize): Declare new function from dl-debug.c. (_r_debug): Declare it. * Makerules (distinfo-vars): Add install-{lib,data,bin,sbin,others}. In distinfo set $(subdir)-VAR and then set VAR to $($(subdir)-VAR). * Makeconfig (rpath-link): New variable; add $(elfobjdir). (default-rpath): Use it. (built-program-cmd): Use it in LD_LIBRARY_PATH. * Makeconfig (sysdep-configures): Prepend $(sysdep_dir) to names tried. * sysdeps/unix/Dist: Add make-syscalls.sh. * misc/Makefile (headers): Add sys/swap.h. * posix/unistd.h: Remove decls for swapon, swapoff. * sysdeps/generic/sys/swap.h: New file. * sysdeps/unix/sysv/linux/sys/swap.h: New file. * sysdeps/unix/sysv/linux/gnu/types.h: Remove temporary hack #define of __kernel_fsid_t. It is correctly defines in now. --- elf/dl-open.c | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'elf/dl-open.c') diff --git a/elf/dl-open.c b/elf/dl-open.c index 9389303b90..373d32dd79 100644 --- a/elf/dl-open.c +++ b/elf/dl-open.c @@ -29,6 +29,7 @@ _dl_open (struct link_map *parent, const char *file, int mode) { struct link_map *new, *l; ElfW(Addr) init; + struct r_debug *r; /* Load the named object. */ @@ -47,7 +48,7 @@ _dl_open (struct link_map *parent, const char *file, int mode) l = new; while (l->l_next) l = l->l_next; - do + while (1) { if (! l->l_relocated) { @@ -56,8 +57,10 @@ _dl_open (struct link_map *parent, const char *file, int mode) *_dl_global_scope_end = NULL; } + if (l == new) + break; l = l->l_prev; - } while (l != new); + } new->l_global = (mode & RTLD_GLOBAL); if (new->l_global) @@ -108,6 +111,14 @@ _dl_open (struct link_map *parent, const char *file, int mode) } } + + /* Notify the debugger we have added some objects.
