Andreas Hansson 71da1d2157 base: Encapsulate the underlying fields in AddrRange
This patch makes the start and end address private in a move to
prevent direct manipulation and matching of ranges based on these
fields. This is done so that a transition to ranges with interleaving
support is possible.

As a result of hiding the start and end, a number of member functions
are needed to perform the comparisons and manipulations that
previously took place directly on the members. An accessor function is
provided for the start address, and a function is added to test if an
address is within a range. As a result of the latter the != and ==
operator is also removed in favour of the member function. A member
function that returns a string representation is also created to allow
debug printing.

In general, this patch does not add any functionality, but it does
take us closer to a situation where interleaving (and more cleverness)
can be added under the bonnet without exposing it to the user. More on
that in a later patch.

This is the gem5 simulator.

For detailed information about building the simulator and getting
started please refer to:

Short version:
External tools and required versions

To build gem5, you will need the following software:
g++ version 4.3 or newer.
Python, version 2.4 - 2.7 (we don't support Python 3.X). gem5 links in the 
    Python interpreter, so you need the Python header files and shared 
    library (e.g., /usr/lib/libpython2.4.so) in addition to the interpreter
    executable. These may or may not be installed by default. For example,
    on Debian/Ubuntu, you need the "python-dev" package in addition to the
    "python" package. If you need a newer or different Python installation
     but can't or don't want to upgrade the default Python on your system,
     see http://www.gem5.org/Using_a_non-default_Python_installation
SCons, version 0.98.1 or newer. SCons is a powerful replacement for make. 
    If you don't have administrator privileges on your machine, you can use the
    "scons-local" package to install scons in your m5 directory, or install SCons
    in your home directory using the '--prefix=' option.  
SWIG, version 1.3.34 or newer
zlib, any recent version. For Debian/Ubuntu, you will need the "zlib-dev" or
    "zlib1g-dev" package to get the zlib.h header file as well as the library
    itself.
m4, the macro processor.


4. In this directory, type 'scons build/<ARCH>/gem5.opt' where ARCH is one
of ALPHA, ARM, MIPS, POWER, SPARC, or X86. This will build an optimized version
of the gem5 binary (gem5.opt) for the the specified architecture.

If you have questions, please send mail to gem5-users@gem5.org

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

The basic source release includes these subdirectories:
 - gem5:
   - configs: example simulation configuration scripts
   - ext: less-common external packages needed to build gem5
   - src: source code of the gem5 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.
