This patch provides optimized versions of strcspn and wcscspn with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strcspn-c.c: New File. * sysdeps/s390/multiarch/strcspn-vx.S: Likewise. * sysdeps/s390/multiarch/strcspn.c: Likewise. * sysdeps/s390/multiarch/wcscspn-c.c: Likewise. * sysdeps/s390/multiarch/wcscspn-vx.S: Likewise. * sysdeps/s390/multiarch/wcscspn.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strcspn and wcscspn functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strcspn, wcscspn. * wcsmbs/wcscspn.c: Use WCSCSPN if defined. * string/test-strcspn.c: Add wcscspn support. * wcsmbs/test-wcscspn.c: New File. * wcsmbs/Makefile (strop-tests): Add wcscspn. * benchtests/bench-strcspn.c: Add wcscspn support. * benchtests/bench-wcscspn.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcscspn. --- sysdeps/s390/multiarch/wcscspn.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 sysdeps/s390/multiarch/wcscspn.c (limited to 'sysdeps/s390/multiarch/wcscspn.c') diff --git a/sysdeps/s390/multiarch/wcscspn.c b/sysdeps/s390/multiarch/wcscspn.c new file mode 100644 index 0000000000..4c92653f7e --- /dev/null +++ b/sysdeps/s390/multiarch/wcscspn.c @@ -0,0 +1,27 @@ +/* Multiple versions of wcscspn. + Copyright (C) 2015 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
