From e9873e1d47c870d707117ada91c9be21e3bf1537 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:21 +0100 Subject: S390: Refactor wcsncmp ifunc handling. The ifunc handling for wcsncmp is adjusted in order to omit ifunc variants if those will never be used as the minimum architecture level already supports newer CPUs by default. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcsncmp variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcsncmp variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcsncmp. * sysdeps/s390/multiarch/wcsncmp-c.c: Move to ... * sysdeps/s390/wcsncmp-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsncmp-vx.S: Move to ... * sysdeps/s390/wcsncmp-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsncmp.c: Move to ... * sysdeps/s390/wcsncmp.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcsncmp.h: New file. --- sysdeps/s390/wcsncmp-c.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 sysdeps/s390/wcsncmp-c.c (limited to 'sysdeps/s390/wcsncmp-c.c') diff --git a/sysdeps/s390/wcsncmp-c.c b/sysdeps/s390/wcsncmp-c.c new file mode 100644 index 0000000000..a9ccb8de82 --- /dev/null +++ b/sysdeps/s390/wcsncmp-c.c @@ -0,0 +1,27 @@ +/* Default wcsncmp implementation for S/390. + Copyright (C) 2015-2018 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.
