From fc2427e81b1c648550d0368652d6a475df785027 Mon Sep 17 00:00:00 2001 From: Gareth Hughes Date: Mon, 23 Oct 2000 00:16:28 +0000 Subject: Major audit of all Mesa's x86 assembly code. This round is basically general cleanups - more to come. Added P6 architecture timing to debug_xform routines. Still need to add test_all_vertex_functions test for the v16 asm. Dynamic reconfiguration of counter overhead for more accurate benchmarking. --- src/mesa/x86/common_x86.c | 109 +++++++++++++++++++++++++++------------------- 1 file changed, 65 insertions(+), 44 deletions(-) (limited to 'src/mesa/x86/common_x86.c') diff --git a/src/mesa/x86/common_x86.c b/src/mesa/x86/common_x86.c index e779fe193ba..93d21161a98 100644 --- a/src/mesa/x86/common_x86.c +++ b/src/mesa/x86/common_x86.c @@ -1,21 +1,21 @@ -/* $Id: common_x86.c,v 1.6 2000/01/25 17:04:47 brianp Exp $ */ +/* $Id: common_x86.c,v 1.7 2000/10/23 00:16:28 gareth Exp $ */ /* * Mesa 3-D graphics library - * Version: 3.3 - * + * Version: 3.5 + * * Copyright (C) 1999-2000 Brian Paul 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, sublicense, * 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 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 NONINFRINGEMENT.
