This patch provides optimized version of wmemset with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/wmemset-c.c: New File. * sysdeps/s390/multiarch/wmemset-vx.S: Likewise. * sysdeps/s390/multiarch/wmemset.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add wmemset functions. * sysdeps/s390/multiarch/ifunc-impl-list-common.c (__libc_ifunc_impl_list_common): Add ifunc test for wmemset. * wcsmbs/wmemset.c: Use WMEMSET if defined. * string/test-memset.c: Add wmemset support. * wcsmbs/test-wmemset.c: New File. * wcsmbs/Makefile (strop-tests): Add wmemset. * benchtests/bench-memset.c: Add wmemset support. * benchtests/bench-wmemset.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wmemset. --- sysdeps/s390/multiarch/ifunc-impl-list.c | 1 + 1 file changed, 1 insertion(+) (limited to 'sysdeps/s390/multiarch/ifunc-impl-list.c') diff --git a/sysdeps/s390/multiarch/ifunc-impl-list.c b/sysdeps/s390/multiarch/ifunc-impl-list.c index c90fb6b6c7..93789acbbe 100644 --- a/sysdeps/s390/multiarch/ifunc-impl-list.c +++ b/sysdeps/s390/multiarch/ifunc-impl-list.c @@ -133,6 +133,7 @@ __libc_ifunc_impl_list (const char *name, struct libc_ifunc_impl *array, IFUNC_VX_IMPL (memccpy); + IFUNC_VX_IMPL (wmemset); #endif /* HAVE_S390_VX_ASM_SUPPORT */ return i; -- cgit v1.2.3
