Change ld.so to not use functions which are exported. One cannot interpose them anyway. Use INT() to mark uses, INTDEF() to mark definitions. * include/libc-symbols.h: Define INT and INTDEF. * sysdeps/generic/ldsodefs.h: Declare _dl_debug_printf_internal, _dl_signal_error_internal, _dl_map_object_internal, _dl_map_object_deps_internal, _dl_lookup_symbol_internal, _dl_lookup_versioned_symbol_internal, _dl_relocate_object_internal, _dl_debug_state_internal, _dl_start_profile_internal, and _dl_unload_cache_internal. * include/dlfcn.h: Declare _dl_catch_error_internal. * elf/rtld.c: Use INT for calls to any of the *_internal functions above. Add INTDEF to function definitions. * elf/dl-debug.c: Likewise. * elf/dl-deps.c: Likewise. * elf/dl-dst.h: Likewise. * elf/dl-error.c: Likewise. * elf/dl-fini.c: Likewise. * elf/dl-init.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-lookup.c: Likewise. * elf/dl-misc.c: Likewise. * elf/dl-open.c: Likewise. * elf/dl-profile.c: Likewise. * elf/dl-reloc.c: Likewise. * elf/dl-runtime.c: Likewise. * elf/dl-version.c: Likewise. * elf/do-lookup.h: Likewise. * sysdeps/generic/dl-cache.c: Likewise. * sysdeps/generic/dl-sysdep.c: Likewise. * sysdeps/alpha/dl-machine.h (RTLD_START): Call _dl_init_internal instead of _dl_init. * sysdeps/arm/dl-machine.h: Likewise. * sysdeps/cris/dl-machine.h: Likewise. * sysdeps/hppa/dl-machine.h: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/ia64/dl-machine.h: Likewise. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/mips/dl-machine.h: Likewise. * sysdeps/mips/mips64/dl-machine.h: Likewise. * sysdeps/s390/s390-32/dl-machine.h: Likewise. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/sh/dl-machine.h: Likewise. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise. * sysdeps/x86_64/dl-machine.h: Likewise. * sysdeps/powerpc/dl-start.S (_dl_start_user): Likewise. * elf/Versions: Don't export _dl_check_all_versions, _dl_sysdep_start, and _dl_debug_initialize.
