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.
