From 70d418c7e6af082933930a0ca0241bd16ebf1a8f Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Mon, 11 Jul 2016 10:03:41 -0400 Subject: Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." This reverts commit 1df908f33f658979b32599489ca6f1a39821013c. The expected performance improvements are essentially non-existent. --- libswscale/ppc/Makefile | 1 - libswscale/ppc/input_vsx.c | 437 --------------------------------------------- 2 files changed, 438 deletions(-) delete mode 100644 libswscale/ppc/input_vsx.c (limited to 'libswscale/ppc') diff --git a/libswscale/ppc/Makefile b/libswscale/ppc/Makefile index 2482893..d1b596e 100644 --- a/libswscale/ppc/Makefile +++ b/libswscale/ppc/Makefile @@ -1,4 +1,3 @@ OBJS += ppc/swscale_altivec.o \ - ppc/input_vsx.o \ ppc/yuv2rgb_altivec.o \ ppc/yuv2yuv_altivec.o \ diff --git a/libswscale/ppc/input_vsx.c b/libswscale/ppc/input_vsx.c deleted file mode 100644 index d977a32..0000000 --- a/libswscale/ppc/input_vsx.c +++ /dev/null @@ -1,437 +0,0 @@ -/* - * Copyright (C) 2016 Dan Parrot - * - * This file is part of FFmpeg. - * - * FFmpeg 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. - * - * FFmpeg 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.
