2000-08-19 Ulrich Drepper <drepper@redhat.com> * elf/Versions [ld] (GLIBC_2.2): Export _dl_check_map_versions. * elf/dl-deps.c (_dl_map_object_deps): If object was dependency of a dynamically loaded object remove old l_initfini list. * elf/dl-libc.c (free_mem): Used as __libc_subfreeres callback to remove some dynamically allocated memory blocks in the dynamic loading data structures. * elf/dl-load.c (add_name_to_object): Initialize dont_free to 0. * elf/dl-open.c (dl_open_workder): Don't call _dl_check_all_versions. Instead call _dl_check_map_versions only for the dependencies. * elf/rtld.c: Avoid unneccessary initializations. Mark l_libname information of initial objects as not free-able. * sysdeps/generic/ldsodefs.h (struct libname_list): Add dont_free element. * elf/filter.c: Call mtrace. * elf/restest1.c: Likewise. Close the objects. * elf/loadtest.c: Call mtrace. Check result of dlclose. Print more debug information. * elf/constload1.c: Add comment explaining not freed memory.
