From f0954299ecdccf6a70cf904b8f499d15a5af3928 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Thu, 8 Oct 2015 13:22:47 +0200 Subject: [PATCH 28/30] S390: Optimize wmemset. upstream-commit-id: 2e9e166761fed5dfaa53480412bef0656f1b5306 https://www.sourceware.org/ml/libc-alpha/2015-07/msg00078.html 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. --- benchtests/Makefile | 2 +- benchtests/bench-memset.c | 63 +++++++++----- benchtests/bench-wmemset.c | 20 +++++ string/test-memset.c | 88 ++++++++++++------- sysdeps/s390/multiarch/Makefile | 3 +- sysdeps/s390/multiarch/ifunc-impl-list.c | 2 + sysdeps/s390/multiarch/wmemset-c.c | 31 +++++++ sysdeps/s390/multiarch/wmemset-vx.S | 142 +++++++++++++++++++++++++++++++ sysdeps/s390/multiarch/wmemset.c | 27 ++++++ wcsmbs/Makefile | 2 +- wcsmbs/test-wmemset-ifunc.c | 20 +++++ wcsmbs/test-wmemset.c | 20 +++++ wcsmbs/wmemset.c | 3 + 13 files changed, 368 insertions(+), 55 deletions(-) create mode 100644 benchtests/bench-wmemset.c create mode 100644 sysdeps/s390/multiarch/wmemset-c.c create mode 100644 sysdeps/s390/multiarch/wmemset-vx.S create mode 100644 sysdeps/s390/multiarch/wmemset.c create mode 100644 wcsmbs/test-wmemset-ifunc.c create mode 100644 wcsmbs/test-wmemset.c diff --git a/benchtests/Makefile b/benchtests/Makefile index b4b3127..b5edfdd 100644 --- a/benchtests/Makefile +++ b/benchtests/Makefile @@ -40,7 +40,7 @@ string-bench := bcopy bzero memccpy memchr memcmp memcpy memmem memmove \ strspn strstr strcpy_chk stpcpy_chk memrchr strsep strtok wcsmbs-bench := wcslen wcsnlen wcscpy wcpcpy wcsncpy wcpncpy wcscat wcsncat \ wcsncmp wcsncmp wcschr wcschrnul wcsrchr wcsspn wcspbrk wcscspn \ - wmemchr + wmemchr wmemset string-bench-all := $(string-bench) ${wcsmbs-bench} stdlib-bench := strtod diff --git a/benchtests/bench-memset.c b/benchtests/bench-memset.c index 9786ce7..66c3c45 100644 --- a/benchtests/bench-memset.c +++ b/benchtests/bench-memset.c @@ -20,12 +20,29 @@ #ifdef TEST_BZERO # define TEST_NAME "bzero" #else -# define TEST_NAME "memset" -#endif +# ifndef WIDE +# define TEST_NAME "memset" +# else +# define TEST_NAME "wmemset" +# endif /* WIDE */ +#endif /* !TEST_BZERO */ #define MIN_PAGE_SIZE 131072 #include "bench-string.h" -char *simple_memset (char *, int, size_t);
