From 3120894c6d33a26cda642246344e8945db200ac2 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Thu, 5 Feb 2009 14:44:17 +0000 Subject: gallium: add new aux lib for index list translations Could this be the ultimate index list translating utility? Maybe, but it doesn't yet include support for splitting primitives. Unlike previous attempts, this captures all possible combinations of API and hardware provoking vertex, supports generated list reuse and various other tricks. Relies on python-generated code. --- src/gallium/auxiliary/indices/Makefile | 16 + src/gallium/auxiliary/indices/SConscript | 17 + src/gallium/auxiliary/indices/u_indices.c | 253 ++ src/gallium/auxiliary/indices/u_indices.h | 83 + src/gallium/auxiliary/indices/u_indices_gen.c | 5129 ++++++++++++++++++++++++ src/gallium/auxiliary/indices/u_indices_gen.py | 318 ++ src/gallium/auxiliary/indices/u_indices_priv.h | 43 + 7 files changed, 5859 insertions(+) create mode 100644 src/gallium/auxiliary/indices/Makefile create mode 100644 src/gallium/auxiliary/indices/SConscript create mode 100644 src/gallium/auxiliary/indices/u_indices.c create mode 100644 src/gallium/auxiliary/indices/u_indices.h create mode 100644 src/gallium/auxiliary/indices/u_indices_gen.c create mode 100644 src/gallium/auxiliary/indices/u_indices_gen.py create mode 100644 src/gallium/auxiliary/indices/u_indices_priv.h (limited to 'src/gallium/auxiliary') diff --git a/src/gallium/auxiliary/indices/Makefile b/src/gallium/auxiliary/indices/Makefile new file mode 100644 index 0000000000..8fa61d265e --- /dev/null +++ b/src/gallium/auxiliary/indices/Makefile @@ -0,0 +1,16 @@ +TOP = ../../../.. +include $(TOP)/configs/current + +LIBNAME = indices + +C_SOURCES = \ + u_indices_gen.c + +include ../../Makefile.template + +u_indices_gen.c: u_indices_gen.py + python $< > $@ + + +symlinks: + diff --git a/src/gallium/auxiliary/indices/SConscript b/src/gallium/auxiliary/indices/SConscript new file mode 100644 index 0000000000..65a43a9f64 --- /dev/null +++ b/src/gallium/auxiliary/indices/SConscript @@ -0,0 +1,17 @@ +Import('*') + +env.CodeGenerate( + target = 'u_indices_gen.c', + script = 'u_indices_gen.py', + source = [], + command = 'python $SCRIPT > $TARGET' +) + +indices = env.ConvenienceLibrary( + target = 'indices', + source = [ +# 'u_indices.c', + 'u_indices_gen.c', + ]) + +auxiliaries.insert(0, indices) diff --git a/src/gallium/auxiliary/indices/u_indices.c b/src/gallium/auxiliary/indices/u_indices.c new file mode 100644 index 0000000000..0cf7d88653 --- /dev/null +++ b/src/gallium/auxiliary/indices/u_indices.c @@ -0,0 +1,253 @@ +/* + * 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 + * on 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.
