This patch introduces a z13 specific ifunc variant for memmove. As the common code implementation, it checks if we can copy from the beginning to the end - with z196 memcpy implementation - or if we have to copy from the end to the beginning. The latter case is done by using vector load/store instructions. If vector instructions are not available, the common-code is used as fallback. Therefore it is implemented in memmove-c with a different name. Furthermore the ifunc logic decides if we need the common-code implementation at all. If vector instructions are supported due to the minimum architecture level set we can skip the common-code ifunc variant. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmove-c. * sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC, HAVE_MEMMOVE_IFUNC_AND_VX_SUPPORT, MEMMOVE_DEFAULT, HAVE_MEMMOVE_C, MEMMOVE_C, HAVE_MEMMOVE_Z13, MEMMOVE_Z13): New defines. * sysdeps/s390/memcpy-z900.S: Add z13 memmove implementation. * sysdeps/s390/memmove-c.c: New file. * sysdeps/s390/memmove.c: Likewise. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for memmove.
