* elf/dl-open.c (_dl_sysdep_start): Wrap weak_extern decl in BP_SYM ().
* include/libc-symbols.h (weak_extern): Add extra level of expansion.
(symbol_version, default_symbol_version): Factor redundant
definitions out of conditional.
* linuxthreads/sysdeps/pthread/bits/libc-lock.h:
Wrap BP_SYM () around weak extern declarations of pthread
functions that have pointers in their return+arg signatures.
* elf/dl-version.c (_dl_check_map_versions): New argument trace_mode.
Before testing versions check that we actually loaded the object
and whether we are in trace mode. If not loaded during tracing don't
test versions in this object.
(_dl_check_all_versions): Take new parameter and pass to
_dl_check_map_versions.
* sysdeps/generic/ldsodefs.h: Update prototypes for
_dl_check_all_versions and _dl_check_map_versions.

(dl_main): Pass info about trace mode to version_check_doit.
* elf/dl-open.c (dl_open_worker): Pass zero as new argument to
_dl_check_all_versions.

2000-03-30 Ulrich Drepper <drepper@redhat.com>
Implement dynamic determination of constructor/destructor order in
the dynamic linker.
* elf/Versions [ld.so] (GLIBC_2.0): Remove _dl_init_next.
(GLIBC_2.2): Add _dl_init.
* elf/dl-close.c: Also call all destructors in FINI_ARRAY.
r_duplist is not anymore allocated separately. l_initfini is and
therefore free it if necessary.
* elf/dl-deps.c: If a searchlist has to be allocated, put all in one
malloc block. Otherwise allocate l_initfini list only.
Put dependencies for the object in l_initfini list.
Sort dependencies for the object to be loaded topologically.
* elf/dl-fini.c: Before running the destructors sort the topologically.
* elf/dl-init.c (_dl_init): Renamed from _dl_init_next. Rewrite to
call constructors instead of iterating over the pointers. Get list of
objects for which to run constructors from l_initfini element. Accept
argc, argv, and env as parameters and pass them to the constructors.
* elf/ld-load.c (_dl_map_object_from_fd): Initialize l_ldnum member
with size of dynamic section.
* elf/dl-open.c (dl_open_worker): Only call _dl_init instead of
_dl_init_next and calling constructors ourself.
* elf/dl-preinit.c (_dl_preinit): Renamed from _dl_preinit_next.
Take argc, argv, and env as parameters and pass them to the
constructors. Rewrite to call all constructors and not iterate over
the pointers.
* elf/dynamic-link.h: Don't relocate DT_FINI_ARRAY entry. Don't
precompute l_initcount and l_preinitcount.
* elf/link.h (struct link_map): Add l_ldnum member.
Make l_phdr_allocated part of the bitfield. Remove l_runcount,
l_initcount, and l_preinitcount. Add l_initfini.
* sysdeps/generic/ldsodefs.h: Replace _dl_init_next prototype with
one for _dl_init.
* sysdeps/i386/dl-machine (RTLD_START): Rewrite to match new init
function interface.
* sysdeps/unix/sysv/linux/init-first.h: Removed.
* sysdeps/unix/sysv/linux/Dist: Delete file here as well.
* sysdeps/unix/sysv/linux/init-first.c [PIC]: Don't use
SYSDEP_CALL_INIT. Make _init a strong alias of init. The calling
conventions now match.
* sysdeps/generic/libc-start.c: Calling __libc_init_first has no
effect for shared objects. Don't emit message and call only for
static library.
* elf/dl-deps.c (_dl_map_object_deps): Change return type and remove
last parameter. Move code to add map to global scope from here...
* elf/dl-open.c (dl_open_worker): ...here.
* elf/ldsodefs.h: Adjust declaration of _dl_map_object_deps.
* elf/rtld.c: Adjust call to _dl_map_object_deps.
* sysdeps/gnu/Makefile (libdl-routines): Add eval.

components, except the ones relating to the test cases.
