Lisa Hsu d857105b5a Ruby: Simplify SLICC and Entry/TBE handling. 
Before this changeset, all local variables of type Entry and TBE were considered
to be pointers, but an immediate use of said variables would not be automatically
deferenced in SLICC-generated code.  Instead, deferences occurred when such
variables were passed to functions, and were automatically dereferenced in
the bodies of the functions (e.g. the implicitly passed cache_entry).

This is a more general way to do it, which leaves in place the
assumption that parameters to functions and local variables of type AbstractCacheEntry
and TBE are always pointers, but instead of dereferencing to access member variables
on a contextual basis, the dereferencing automatically occurs on a type basis at the
moment a member is being accessed.  So, now, things you can do that you couldn't before
include:

Entry foo := getCacheEntry(address);
cache_entry.DataBlk := foo.DataBlk;

or

cache_entry.DataBlk := getCacheEntry(address).DataBlk;

or even

cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk;

README 

This is 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 0.98.1 or newer, get it from
http://wwww.scons.org.

2. If you don't have SWIG version 1.3.31 or newer, get it from
http://wwww.swig.org.

3. Make sure you also have gcc version 3.4.6 or newer, Python 2.4 or newer
(the dev version with header files), zlib, and the m4 preprocessor.

4. 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:
   - configs: simulation configuration scripts
   - ext: less-common external packages needed to build m5
   - src: source code of the m5 simulator
   - system: source for some optional system software for simulated systems
   - tests: regression tests
   - util: useful utility programs and files

To run full-system simulations, you will need compiled system firmware
(console and PALcode for Alpha), kernel binaries and one or more disk images. 
These files for Alpha are collected in a separate archive, m5_system.tar.bz2.
This file can he downloaded separately.

Depending on the ISA used, M5 may support 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
