Korey Sewell 19ca97af79 This changeset gets the MIPS ISA pretty much working in the O3CPU. It builds, runs, and gets very very close to completing the hello world
succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!

Anyways, a lot of this stuff had to do with my project at MIPS and me needing to know how I was going to get this working for the MIPS
ISA. So I figured I would try to touch it up and throw it in here (I hate to introduce non-completely working components... )

This is release 2.0 of the M5 simulator.

For information about building the simulator and getting started please refer
to: http://m5.eecs.umich.edu/

Specific Pages of Interest are:
http://m5.eecs.umich.edu/wiki/index.php/Compiling_M5
http://m5.eecs.umich.edu/wiki/index.php/Running_M5

If you have questions, please send mail to m5sim-users@lists.sourceforge.net.

WHAT'S INCLUDED (AND NOT)
-------------------------

The basic source release includes these subdirectories:
 - m5: 
   - src: source code of the m5 simulator
   - test: regression tests
   - ext: less-common external packages needed to build m5
   - system/alpha: source for Alpha console and PALcode

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_2.0.tar.bz2.  This file
is included on the CD release, or you can download it separately from
Sourceforge.

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-dev@eecs.umich.edu.

The CD release includes a few extra goodies, such as a tar file
containing doxygen-generated HTML documentation (html-docs.tar.gz), a
set of Linux source patches (linux_m5-2.6.8.1.diff), and the scons
program needed to build M5.  If you do not have the CD, the same HTML
documentation is available online at http://m5.eecs.umich.edu/docs,
the Linux source patches are available at
http://m5.eecs.umich.edu/dist/linux_m5-2.6.8.1.diff, the scons
program is available from http://www.scons.org, and swig is available from
http://www.swig.org.
