Update.
2004-09-23 Ulrich Drepper <drepper@redhat.com>
* sysdeps/generic/bits/dlfcn.h: Add RTLD_DEEPBIND.
* elf/dl-object.c (_dl_new_object): Add new parameter mode. If mode
has RTLD_DEEPBIND set add local searchlist before global scope.
* sysdeps/generic/ldsodefs.h (_dl_new_object): Adjust prototype.
* elf/rtld.c: Adjust callers of _dl_new_object.
* elf/dl-load.c: Likewise.
(_dl_map_object_from_fd): If RTLD_DEEPBIND is used, don't do anything
for DF_SYMBOLIC.
* elf/dl-open.c (dl_open_writer): Pass RTLD_DEEPBIND flag on to
_dl_map_object_deps.
* elf/tst-deep1.c: New file.
* elf/tst-deep1mod1.c: New file.
* elf/tst-deep1mod2.c: New file.
* elf/tst-deep1mod3.c: New file.
* elf/Makefile: Add rules to build and run new tests.
* elf/dl-deps.c: Pretty printing.
