This patch provides optimized versions of strchr and wcschr with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strchr-c.c: New File. * sysdeps/s390/multiarch/strchr-vx.S: Likewise. * sysdeps/s390/multiarch/strchr.c: Likewise. * sysdeps/s390/multiarch/wcschr-c.c: Likewise. * sysdeps/s390/multiarch/wcschr-vx.S: Likewise. * sysdeps/s390/multiarch/wcschr.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strchr and wcschr functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strchr, wcschr. * string/strchr.c (STRCHR): Define and use macro. * benchtests/bench-wcschr.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcschr. --- benchtests/Makefile | 2 +- benchtests/bench-wcschr.c | 20 ++++++++++++++++++++ 2 files changed, 21 insertions(+), 1 deletion(-) create mode 100644 benchtests/bench-wcschr.c (limited to 'benchtests') diff --git a/benchtests/Makefile b/benchtests/Makefile index 0a857974d2..b931f60077 100644 --- a/benchtests/Makefile +++ b/benchtests/Makefile @@ -37,7 +37,7 @@ string-bench := bcopy bzero memccpy memchr memcmp memcpy memmem memmove \ strspn strstr strcpy_chk stpcpy_chk memrchr strsep strtok \ strcoll wcsmbs-bench := wcslen wcsnlen wcscpy wcpcpy wcsncpy wcpncpy wcscat wcsncat \ - wcscmp wcsncmp + wcscmp wcsncmp wcschr string-bench-all := $(string-bench) ${wcsmbs-bench} # We have to generate locales diff --git a/benchtests/bench-wcschr.c b/benchtests/bench-wcschr.c new file mode 100644 index 0000000000..428772444f --- /dev/null +++ b/benchtests/bench-wcschr.c @@ -0,0 +1,20 @@ +/* Measure wcschr functions. + 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.
