From 196655ba54ebdcdcc0468bcb6e136757b013d350 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:16 +0100 Subject: S390: Refactor memccpy ifunc handling. The ifunc handling for memccpy 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 memccpy variants. * sysdeps/s390/Makefile (sysdep_routines): Add memccpy variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for memccpy. * sysdeps/s390/multiarch/memccpy-c.c: Move to ... * sysdeps/s390/memccpy-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/memccpy-vx.S: Move to ... * sysdeps/s390/memccpy-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/memccpy.c: Move to ... * sysdeps/s390/memccpy.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-memccpy.h: New file. --- sysdeps/s390/Makefile | 3 +- sysdeps/s390/ifunc-memccpy.h | 52 ++++++++++ sysdeps/s390/memccpy-c.c | 29 ++++++ sysdeps/s390/memccpy-vx.S | 164 +++++++++++++++++++++++++++++++ sysdeps/s390/memccpy.c | 39 ++++++++ sysdeps/s390/multiarch/Makefile | 3 +- sysdeps/s390/multiarch/ifunc-impl-list.c | 15 ++- sysdeps/s390/multiarch/memccpy-c.c | 25 ----- sysdeps/s390/multiarch/memccpy-vx.S | 156 ----------------------------- sysdeps/s390/multiarch/memccpy.c | 28 ------ 10 files changed, 300 insertions(+), 214 deletions(-) create mode 100644 sysdeps/s390/ifunc-memccpy.h create mode 100644 sysdeps/s390/memccpy-c.c create mode 100644 sysdeps/s390/memccpy-vx.S create mode 100644 sysdeps/s390/memccpy.c delete mode 100644 sysdeps/s390/multiarch/memccpy-c.c delete mode 100644 sysdeps/s390/multiarch/memccpy-vx.S delete mode 100644 sysdeps/s390/multiarch/memccpy.c (limited to 'sysdeps/s390') diff --git a/sysdeps/s390/Makefile b/sysdeps/s390/Makefile index a181eeac8a..649f29adc2 100644 --- a/sysdeps/s390/Makefile +++ b/sysdeps/s390/Makefile @@ -77,5 +77,6 @@ sysdep_routines += bzero memset memset-z900 \ strpbrk strpbrk-vx strpbrk-c \ strcspn strcspn-vx strcspn-c \ memchr memchr-vx memchr-z900 \ - rawmemchr rawmemchr-vx rawmemchr-c + rawmemchr rawmemchr-vx rawmemchr-c \ + memccpy memccpy-vx memccpy-c endif diff --git a/sysdeps/s390/ifunc-memccpy.h b/sysdeps/s390/ifunc-memccpy.h new file mode 100644 index 0000000000..8f7a1d0f9f --- /dev/null +++ b/sysdeps/s390/ifunc-memccpy.h @@ -0,0 +1,52 @@ +/* memccpy variant information on S/390 version. + 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.
