From 880e2aa23645ed9871c66ee1cbd00f93c72d2d73 Mon Sep 17 00:00:00 2001 From: Diego Biurrun Date: Fri, 30 May 2014 03:44:12 -0700 Subject: Remove all Blackfin architecture optimizations Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden. --- libswscale/bfin/Makefile | 3 - libswscale/bfin/internal_bfin.S | 599 ---------------------------------------- libswscale/bfin/swscale_bfin.c | 84 ------ libswscale/bfin/yuv2rgb_bfin.c | 197 ------------- libswscale/swscale.h | 2 + libswscale/swscale_internal.h | 16 -- libswscale/swscale_unscaled.c | 2 - libswscale/version.h | 3 + libswscale/yuv2rgb.c | 2 - 9 files changed, 5 insertions(+), 903 deletions(-) delete mode 100644 libswscale/bfin/Makefile delete mode 100644 libswscale/bfin/internal_bfin.S delete mode 100644 libswscale/bfin/swscale_bfin.c delete mode 100644 libswscale/bfin/yuv2rgb_bfin.c (limited to 'libswscale') diff --git a/libswscale/bfin/Makefile b/libswscale/bfin/Makefile deleted file mode 100644 index 5f34550427..0000000000 --- a/libswscale/bfin/Makefile +++ /dev/null @@ -1,3 +0,0 @@ -OBJS += bfin/internal_bfin.o \ - bfin/swscale_bfin.o \ - bfin/yuv2rgb_bfin.o \ diff --git a/libswscale/bfin/internal_bfin.S b/libswscale/bfin/internal_bfin.S deleted file mode 100644 index dca8448a3f..0000000000 --- a/libswscale/bfin/internal_bfin.S +++ /dev/null @@ -1,599 +0,0 @@ -/* - * Copyright (C) 2007 Marc Hoffman - * April 20, 2007 - * - * Blackfin video color space converter operations - * convert I420 YV12 to RGB in various formats - * - * 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.
