From fc8e0b97e53fc94b9bafa038cd4420a9588e62f7 Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Thu, 31 Dec 2009 21:41:24 +0000 Subject: gallium: Remove the sct module. Not used, and its functionality is now addressed by pipe_context::is_texture/buffer_referenced callbacks. --- src/gallium/auxiliary/sct/Makefile | 9 - src/gallium/auxiliary/sct/SConscript | 9 - src/gallium/auxiliary/sct/sct.c | 453 ----------------------------------- src/gallium/auxiliary/sct/sct.h | 123 ---------- src/gallium/auxiliary/sct/usage.c | 61 ----- 5 files changed, 655 deletions(-) delete mode 100644 src/gallium/auxiliary/sct/Makefile delete mode 100644 src/gallium/auxiliary/sct/SConscript delete mode 100644 src/gallium/auxiliary/sct/sct.c delete mode 100644 src/gallium/auxiliary/sct/sct.h delete mode 100644 src/gallium/auxiliary/sct/usage.c (limited to 'src/gallium/auxiliary/sct') diff --git a/src/gallium/auxiliary/sct/Makefile b/src/gallium/auxiliary/sct/Makefile deleted file mode 100644 index a7d111b6891..00000000000 --- a/src/gallium/auxiliary/sct/Makefile +++ /dev/null @@ -1,9 +0,0 @@ -TOP = ../../../.. -include $(TOP)/configs/current - -LIBNAME = sct - -C_SOURCES = \ - sct.c - -include ../../Makefile.template diff --git a/src/gallium/auxiliary/sct/SConscript b/src/gallium/auxiliary/sct/SConscript deleted file mode 100644 index 76927d973f8..00000000000 --- a/src/gallium/auxiliary/sct/SConscript +++ /dev/null @@ -1,9 +0,0 @@ -Import('*') - -sct = env.ConvenienceLibrary( - target = 'sct', - source = [ - 'sct.c' - ]) - -auxiliaries.insert(0, sct) diff --git a/src/gallium/auxiliary/sct/sct.c b/src/gallium/auxiliary/sct/sct.c deleted file mode 100644 index 722d2b7e66e..00000000000 --- a/src/gallium/auxiliary/sct/sct.c +++ /dev/null @@ -1,453 +0,0 @@ -/************************************************************************** - * - * Copyright 2008 Tungsten Graphics, Inc., Cedar Park, Texas. - * All Rights Reserved. - * - * Permission is hereby granted, free of charge, to any person obtaining a - * copy of this software and associated documentation files (the - * "Software"), to deal in the Software without restriction, including - * without limitation the rights to use, copy, modify, merge, publish, - * distribute, sub license, and/or sell copies of the Software, and to - * permit persons to whom the Software is furnished to do so, subject to - * the following conditions: - * - * The above copyright notice and this permission notice (including the - * next paragraph) shall be included in all copies or substantial portions - * of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS - * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF - * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. - * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR - * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, - * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE - * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - * - **************************************************************************/ - - -#include "util/u_memory.h" -#include "pipe/p_state.h" -#include "sct.h" - - -struct texture_list -{ - struct pipe_texture *texture;
