Mark internal dirent functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. __readdir64 is hidden with libc_hidden_proto and libc_hidden_def since the exported readdir64 is an alias of __readdir64. [BZ #18822] * include/dirent.h (__opendir): Always add attribute_hidden. (__fdopendir): Likewise. (__closedir): Likewise. (__readdir): Likewise. (__readdir64): Add libc_hidden_proto. * sysdeps/mach/hurd/readdir64.c (__readdir64): Add libc_hidden_def. * sysdeps/unix/sysv/linux/i386/readdir64.c (__readdir64): Likewise. * sysdeps/unix/sysv/linux/readdir64.c (__readdir64): Likewise. * sysdeps/unix/sysv/linux/wordsize-64/readdir.c (__GI___readdir64): New alias.
