* elf/elf.h: Add various DF_1_*, DTF_1_*, and DF_P1_* entries. * elf/dl-close.c (_dl_close): Don't close an object if it is marked with nodelete. * elf/dl-open.c (dl_open_worker): Pass RTLD_NOLOAD as new parameter to _dl_map_object. Return immediately if no object loaded. Set DF_1_NODELETE bit in l_flags_1 if RTLD_NODELETE was passed. * elf/dynamic-link.h (elf_get_dynamic_info): Copy DT_FLAGS_1 entry if it exists into l_flags_1 word. * elf/dl-load.c (_dl_map_object_from_fd): Take no parameter and use it to determine whether loading is wanted or not. (_dl_map_object): Likewise. Call _dl_map_object_from_fd with new parameter. * sysdeps/generic/ldsodefs.h: Update prototype. * elf/dl-deps.c: Add new parameter to _dl_map_object calls. * elf/rtld.c: Likewise. * elf/Makefile (tests): Add noload. Add rules to generate noload. * elf/noload.c: New file. * include/link.h (struct link_map): Add l_feature_1 and l_flags_1. * sysdeps/generic/bits/dlfcn.h: Define RTLD_NOLOAD and RTLD_NODELETE. * sysdeps/mips/bits/dlfcn.h: Likewise.
