From dacc8ffa420575038f04c543c31065fea81d5732 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 30 Mar 2000 16:30:49 +0000 Subject: Update. 2000-03-30 Ulrich Drepper 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/dynamic-link.h | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'elf/dynamic-link.h') diff --git a/elf/dynamic-link.h b/elf/dynamic-link.h index cd30656ff3..5987707e9c 100644 --- a/elf/dynamic-link.h +++ b/elf/dynamic-link.h @@ -114,19 +114,6 @@ elf_get_dynamic_info (struct link_map *l) if (flags & DF_BIND_NOW) info[DT_BIND_NOW] = info[DT_FLAGS]; } -#ifndef DL_RO_DYN_SECTION - /* Determine how many constructors there are. */ - if (info[DT_INIT_ARRAY] != NULL) - info[DT_INIT_ARRAY]->d_un.d_ptr += l_addr; -#endif - l->l_initcount = 1 + (info[DT_INIT_ARRAY] - ?
