From 8c25dddd2e32bce47dfe01ca51c8aab535dbe23d Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:09 +0100 Subject: S390: Add z13 strstr ifunc variant. The new vector variant of strstr is using the common code implementation, but instead of calling the default str* / mem* functions, the vector variants are called. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add strstr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for strstr. * sysdeps/s390/ifunc-strstr.h: New file. * sysdeps/s390/strstr.c: Likewise. * sysdeps/s390/strstr-c.c: Likewise. * sysdeps/s390/strstr-vx.c: Likewise. --- sysdeps/s390/strstr-c.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 sysdeps/s390/strstr-c.c (limited to 'sysdeps/s390/strstr-c.c') diff --git a/sysdeps/s390/strstr-c.c b/sysdeps/s390/strstr-c.c new file mode 100644 index 0000000000..53717bfb27 --- /dev/null +++ b/sysdeps/s390/strstr-c.c @@ -0,0 +1,32 @@ +/* Default strstr implementation for S/390. + Copyright (C) 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.
