This was somewhat tricky because the RefCnt API was somewhat odd. The biggest confusion was that the the RefCnt object's constructor that took a TYPE& cloned the object. I created an explicit virtual clone() function for things that took advantage of this version of the constructor. I was conservative and used clone() when I was in doubt of whether or not it was necessary. I still think that there are probably too many instances of clone(), but hopefully not too many. I converted several instances of const MsgPtr & to a simple MsgPtr. If the function wants to avoid the overhead of creating another reference, then it should just use a regular pointer instead of a ref counting ptr. There were a couple of instances where refcounted objects were created on the stack. This seems pretty dangerous since if you ever accidentally make a reference to that object with a ref counting pointer, bad things are bound to happen.
This is release 2.0_beta6 of the M5 simulator. For detailed information about building the simulator and getting started please refer to http://www.m5sim.org. Specific pages of interest are: http://www.m5sim.org/wiki/index.php/Compiling_M5 http://www.m5sim.org/wiki/index.php/Running_M5 Short version: 1. If you don't have SCons version 0.96.91 or newer, get it from http://wwww.scons.org. 2. If you don't have SWIG version 1.3.28 or newer, get it from http://wwww.swig.org. 3. In this directory, type 'scons build/ALPHA_SE/tests/debug/quick'. This will build the debug version of the m5 binary (m5.debug) for the Alpha syscall emulation target, and run the quick regression tests on it. If you have questions, please send mail to m5-users@m5sim.org WHAT'S INCLUDED (AND NOT) ------------------------- The basic source release includes these subdirectories: - m5: - src: source code of the m5 simulator - tests: regression tests - ext: less-common external packages needed to build m5 To run full-system simulations, you will need compiled console, PALcode, and kernel binaries and one or more disk images. These files are collected in a separate archive, m5_system.tar.bz2. This file can he downloaded separately. M5 supports Linux 2.4/2.6, FreeBSD, and the proprietary Compaq/HP Tru64 version of Unix. We are able to distribute Linux and FreeBSD bootdisks, but we are unable to distribute bootable disk images of Tru64 Unix. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-users@m5sim.org
