Update.
1999-07-24 Ulrich Drepper <drepper@cygnus.com> * elf/dl-fini.c: Handle DT_FINI_ARRAY. * elf/link.h (struct link_map): Remove l_init_running. Add l_runcount and l_initcount. * elf/dl-init.c: Handle DT_INIT_ARRAY. * elf/dynamic-link.h: Change parameters. Now only get link_map pointer. Calculate l_initcount. * elf/link.h (struct link_map): Add l_runpath_dirs. * elf/dynamic-link.h: If RUNPATH is given, set RPATH to NULL. * elf/dl-load.c: Pretty print. (decompose_rpath): Take new parameter with info from where the path comes. Pass it the fillin_rpath. (_dl_init_paths): Initialize l_runpath_dirs. (_dl_map_object): Don't search using RPATHs if object has RUNPATH. Search using RUNPATH after LD_LIBRARY_PATH. * elf/dl-support.c: Adjust comment. * elf/rtld.c: Adjust help message.
