From bb2542e0ae6f82197e804e7e9b78fed461553fc0 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 19 Nov 2014 15:24:55 -0500 Subject: powerpc: Add powerpc64 strcspn optimization This patch makes the POWER7 optimized strcspn generic by using default doubleword stores to zero the hash, instead of VSX instructions. Performance on POWER7/POWER8 does not change. --- .../powerpc/powerpc64/multiarch/strcspn-ppc64.c | 30 ---------------------- 1 file changed, 30 deletions(-) delete mode 100644 sysdeps/powerpc/powerpc64/multiarch/strcspn-ppc64.c (limited to 'sysdeps/powerpc/powerpc64/multiarch/strcspn-ppc64.c') diff --git a/sysdeps/powerpc/powerpc64/multiarch/strcspn-ppc64.c b/sysdeps/powerpc/powerpc64/multiarch/strcspn-ppc64.c deleted file mode 100644 index 5f8b61054d..0000000000 --- a/sysdeps/powerpc/powerpc64/multiarch/strcspn-ppc64.c +++ /dev/null @@ -1,30 +0,0 @@ -/* Copyright (C) 2014 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.
