[PATCH] Kill memmove PLT slot on s390x


Hi!

bcopy.os is the only object with
U memmove
on s390x.  There is another unnecessary PLT slot on both s390 and s390x
- ffs, but that looks like a compiler bug.

2005-07-12  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/s390/s390-64/bcopy.S (__bcopy): Use
	HIDDEN_BUILTIN_JUMPTARGET to jump to memmove.
