This patch introduces the new arch13 ifunc variant for memmem. For needles longer than 9 bytes it is relying on the common-code implementation. For shorter needles it is using the new vstrs instruction which is able to search a substring within a vector register. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmem-arch13. * sysdeps/s390/ifunc-memmem.h (HAVE_MEMMEM_ARCH13, MEMMEM_ARCH13, MEMMEM_Z13_ONLY_USED_AS_FALLBACK, HAVE_MEMMEM_IFUNC_AND_ARCH13_SUPPORT): New defines. * sysdeps/s390/memmem-arch13.S: New file. * sysdeps/s390/memmem-vx.c: Omit GI symbol for z13 memmem ifunc variant if it is only used as fallback. * sysdeps/s390/memmem.c (memmem): Add arch13 variant in ifunc selector. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variant for arch13 memmem.
