--- Comment #3 from H.J. Lu <hjl.tools at gmail dot com> ---
There are

# if !defined _HAVE_STRING_ARCH_mempcpy || defined _FORCE_INLINES
#  ifndef _HAVE_STRING_ARCH_mempcpy
#   if __GNUC_PREREQ (3, 4)
#    define __mempcpy(dest, src, n) __builtin_mempcpy (dest, src, n)
#   elif __GNUC_PREREQ (3, 0)
#    define __mempcpy(dest, src, n) \
  (__extension__ (__builtin_constant_p (src) && __builtin_constant_p (n)      \
                  && __string2_1bptr_p (src) && n <= 8                        \
                  ? __builtin_memcpy (dest, src, n) + (n)                     \
                  : __mempcpy (dest, src, n)))
#   else
#    define __mempcpy(dest, src, n) \
  (__extension__ (__builtin_constant_p (src) && __builtin_constant_p (n)      \
                  && __string2_1bptr_p (src) && n <= 8                        \
                  ? __mempcpy_small (dest, __mempcpy_args (src), n)           \
                  : __mempcpy (dest, src, n)))
#   endif
/* In glibc we use this function frequently but for namespace reasons
   we have to use the name `__mempcpy'.  */
#   define mempcpy(dest, src, n) __mempcpy (dest, src, n)
#  endif

in string/bits/string2.h.  commit 05a910f7b420c2b831f35ba90e61c80f001c0606
should be reverted.
