From bec90733b9de6e7d75b8bda19b3f0a7117e6b78d Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Thu, 2 Sep 2004 14:39:38 +0000 Subject: Add a couple of mips-specific string funcs. Port the generic optimized string funcs from glibc, with some tweaks to cut their size a little. The main change is making memmove call memcpy for forward copying to trim redundant code. Make use of both the generic and arch-specific speed-optimized string funcs configurable. Arch-specific take precedence over generic, and generic takes precedence over basic size-optimized uClibc funcs. --- libc/string/generic/strspn.c | 46 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 libc/string/generic/strspn.c (limited to 'libc/string/generic/strspn.c') diff --git a/libc/string/generic/strspn.c b/libc/string/generic/strspn.c new file mode 100644 index 000000000..dcf8b135d --- /dev/null +++ b/libc/string/generic/strspn.c @@ -0,0 +1,46 @@ +/* Copyright (C) 1991, 1997, 2003 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.
