From dacfef158943665fc0d11035867d14ff1f5db332 Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Fri, 25 Apr 2008 18:18:48 +0900 Subject: gallium: New configuration header. To abstract all those weird #ifdef (__???__) checks. It should typically be the first included header. --- src/gallium/include/pipe/p_compiler.h | 2 + src/gallium/include/pipe/p_config.h | 112 ++++++++++++++++++++++++++++++++++ 2 files changed, 114 insertions(+) create mode 100644 src/gallium/include/pipe/p_config.h (limited to 'src') diff --git a/src/gallium/include/pipe/p_compiler.h b/src/gallium/include/pipe/p_compiler.h index 91f3d2ac2d9..a4b772bc4fd 100644 --- a/src/gallium/include/pipe/p_compiler.h +++ b/src/gallium/include/pipe/p_compiler.h @@ -29,6 +29,8 @@ #define P_COMPILER_H +#include "p_config.h" + #include #include diff --git a/src/gallium/include/pipe/p_config.h b/src/gallium/include/pipe/p_config.h new file mode 100644 index 00000000000..e44fafeae9f --- /dev/null +++ b/src/gallium/include/pipe/p_config.h @@ -0,0 +1,112 @@ +/************************************************************************** + * + * 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. + * + **************************************************************************/ + +/** + * @file + * Gallium configuration defines. + * + * This header file sets several defines based on the compiler, processor + * architecture, and operating system being used.
