On the Hurd, the rtld needs to see its own dumb versions of a few functions (defined in sysdeps/mach/hurd/dl-sysdep.c) overridden by libc's versions once loaded. rtld should thus not have hidden attribute for these. To achieve this, the Hurd port used to just define NO_HIDDEN, which disables it completely. For now, this changes that to disabling it for all rtld functions, for simplicity. See Roland's comment on https://sourceware.org/bugzilla/show_bug.cgi?id=15605#c5 The ld.so numbers remain at 8 .rel.plt 000000c8 00000c24 00000c24 00000c24 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 9 .plt 000001a0 00000cf0 00000cf0 00000cf0 2**4 CONTENTS, ALLOC, LOAD, READONLY, CODE 10 .plt.got 00000010 00000e90 00000e90 00000e90 2**3 CONTENTS, ALLOC, LOAD, READONLY, CODE 18 .got.plt 00000070 0002d000 0002d000 0002c000 2**2 CONTENTS, ALLOC, LOAD, DATA which is about 3 times as much as on Linux. The libc.so numbers get divided by 3 (the remainings are mostly RPC stub calls) * include/libc-symbols.h [NO_RTLD_HIDDEN] (rtld_hidden_proto, rtld_hidden_tls_proto, rtld_hidden_def, rtld_hidden_weak, rtld_hidden_rtld_hidden_ver, data_def, rtld_hidden_data_weak, rtld_hidden_data_ver): Define to empty. * include/assert.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__assert_fail, __assert_perror_fail): Likewise. * include/dirent.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__rewinddir): Likewise. * include/libc-internal.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__profile_frequency): Likewise. * include/setjmp.h (__sigsetjmp): Likewise. * include/signal.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__sigaction, __libc_sigaction): Likewise. * include/stdlib.h [NO_RTLD_HIDDEN] (unsetenv, __strtoul_internal): Do not set hidden attribute. * include/string.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__stpcpy, __strdup, __strerror_t, __strsep_g, memchr, memcmp, memcpy, memmove, memset, rawmemchr, stpcpy, strchr, strcmp, strlen, strnlen, strsep): Likewise. * include/sys/stat.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__fxstat, __fxstat64, __lxstat, __lxstat64, __xstat, __xstat64, __fxstatat64): Likewise. * include/sys/utsname.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (__uname): Likewise. * include/sysdeps/generic/_itoa.h [IS_IN(rtld) && NO_RTLD_HIDDEN] (_itoa_upper_digits, _itoa_lower_digits): Likewise. * sysdeps/mach/hurd/configure.ac (NO_HIDDEN): Do not set.
