From 38a1f0b5d1062f8051ac6bb4e3c35fbbf4615163 Mon Sep 17 00:00:00 2001 From: Michal Krol Date: Fri, 13 Nov 2009 03:02:14 +0100 Subject: [PATCH] glsl/apps: Add GLSL compiler that translates source text into binary stream. Should be used in place of gc_to_bin utility to precompile builtin library. --- src/glsl/apps/SConscript | 7 +- src/glsl/apps/compile.c | 213 +++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 219 insertions(+), 1 deletion(-) create mode 100644 src/glsl/apps/compile.c diff --git a/src/glsl/apps/SConscript b/src/glsl/apps/SConscript index 5802011..4a89e3f 100644 --- a/src/glsl/apps/SConscript +++ b/src/glsl/apps/SConscript @@ -7,7 +7,7 @@ if env['platform'] == 'windows': 'user32', ]) -env.Prepend(LIBS = [glsl]) +env.Prepend(LIBS = [glsl, glslcl]) env.Program( target = 'purify', @@ -28,3 +28,8 @@ env.Program( target = 'process', source = ['process.c'], ) + +env.Program( + target = 'compile', + source = ['compile.c'], +) diff --git a/src/glsl/apps/compile.c b/src/glsl/apps/compile.c new file mode 100644 index 0000000..f99d141 --- /dev/null +++ b/src/glsl/apps/compile.c @@ -0,0 +1,213 @@ +/************************************************************************** + * + * Copyright 2009 VMware, Inc. + * 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 +#include +#include +#include +#include "../pp/sl_pp_public.h" +#include "../cl/sl_cl_parse.h" + + +int +main(int argc, + char *argv[]) +{ + FILE *in;
