From 98c94cfe3ce83634f3bad79ca18263f42e36ca6a Mon Sep 17 00:00:00 2001
From: Steve Reinhardt <steve.reinhardt@amd.com>
Date: Fri, 29 Jan 2010 20:29:17 -0800
Subject: ruby: Convert most Ruby objects to M5 SimObjects. The necessary
 companion conversion of Ruby objects generated by SLICC are converted to M5
 SimObjects in the following patch, so this patch alone does not compile.
 Conversion of Garnet network models is also handled in a separate patch; that
 code is temporarily disabled from compiling to allow testing of interim code.
