From 5046dbb4a7eba5eccfd258f92f4735c9ffc8d069 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Thu, 8 Jun 2017 15:39:03 -0400 Subject: Prepare for radical source tree reorganization. All top-level files and directories are moved into a temporary storage directory, REORG.TODO, except for files that will certainly still exist in their current form at top level when we're done (COPYING, COPYING.LIB, LICENSES, NEWS, README), all old ChangeLog files (which are moved to the new directory OldChangeLogs, instead), and the generated file INSTALL (which is just deleted; in the new order, there will be no generated files checked into version control). --- REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S | 69 +++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S (limited to 'REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S') diff --git a/REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S b/REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S new file mode 100644 index 0000000000..d102c7e80b --- /dev/null +++ b/REORG.TODO/sysdeps/x86_64/multiarch/strcspn.S @@ -0,0 +1,69 @@ +/* Multiple versions of strcspn + All versions must be listed in ifunc-impl-list.c. + Copyright (C) 2009-2017 Free Software Foundation, Inc. + Contributed by Intel Corporation. + 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.
