From 8506ff97c9ea4a1f52983497ecf8d4ef193403a9 Mon Sep 17 00:00:00 2001 From: Diego Biurrun Date: Sat, 6 Oct 2012 20:28:56 +0200 Subject: vp56: Mark VP6-only optimizations as such. Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds. --- libavcodec/x86/vp6dsp_init.c | 45 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 libavcodec/x86/vp6dsp_init.c (limited to 'libavcodec/x86/vp6dsp_init.c') diff --git a/libavcodec/x86/vp6dsp_init.c b/libavcodec/x86/vp6dsp_init.c new file mode 100644 index 0000000000..c4a500b28a --- /dev/null +++ b/libavcodec/x86/vp6dsp_init.c @@ -0,0 +1,45 @@ +/* + * VP6 MMX/SSE2 optimizations + * Copyright (C) 2009 Sebastien Lucas + * Copyright (C) 2009 Zuxy Meng + * + * This file is part of Libav. + * + * Libav 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. + * + * Libav 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.
