From: Keith Whitwell Date: Thu, 5 Feb 2009 14:44:17 +0000 (+0000) Subject: gallium: add new aux lib for index list translations X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3120894c6d33a26cda642246344e8945db200ac2;p=mesa.git 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. --- diff --git a/configs/default b/configs/default index 40f3a2a02dc..13bda58f188 100644 --- a/configs/default +++ b/configs/default @@ -89,7 +89,7 @@ PROGRAM_DIRS = demos redbook samples glsl xdemos EGL_DRIVERS_DIRS = demo # Gallium directories and -GALLIUM_AUXILIARY_DIRS = draw translate cso_cache pipebuffer tgsi sct rtasm util +GALLIUM_AUXILIARY_DIRS = draw translate cso_cache pipebuffer tgsi sct rtasm util indices GALLIUM_AUXILIARIES = $(foreach DIR,$(GALLIUM_AUXILIARY_DIRS),$(TOP)/src/gallium/auxiliary/$(DIR)/lib$(DIR).a) GALLIUM_DRIVER_DIRS = softpipe i915simple i965simple nv04 nv10 nv20 nv30 nv40 nv50 failover trace GALLIUM_DRIVERS = $(foreach DIR,$(GALLIUM_DRIVER_DIRS),$(TOP)/src/gallium/drivers/$(DIR)/lib$(DIR).a) diff --git a/src/gallium/SConscript b/src/gallium/SConscript index 85baf51a7f0..0c632ac2b8b 100644 --- a/src/gallium/SConscript +++ b/src/gallium/SConscript @@ -21,6 +21,7 @@ SConscript([ 'auxiliary/translate/SConscript', 'auxiliary/draw/SConscript', 'auxiliary/pipebuffer/SConscript', + 'auxiliary/indices/SConscript', ]) for driver in env['drivers']: diff --git a/src/gallium/auxiliary/indices/Makefile b/src/gallium/auxiliary/indices/Makefile new file mode 100644 index 00000000000..8fa61d265ea --- /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 00000000000..65a43a9f648 --- /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 00000000000..0cf7d88653c --- /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.
