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. |
