The major thrust of this change is to limit the amount of code
duplication surrounding the code for these functions. This code also
adds two new message types called info and hack. Info is meant to be
less harsh than warn so people don't get confused and start thinking
that the simulator is broken. Hack is a way for people to add runtime
messages indicating that the simulator just executed a code "hack"
that should probably be fixed. The benefit of knowing about these
code hacks is that it will let people know what sorts of inaccuracies
or potential bugs might be entering their experiments. Finally, I've
added some flags to turn on and off these message types so command
line options can change them.
If the same dictionary option is seen in several options, those
dictionaries are composed. If you define the same dictionary key in
multiple options, the system flags an error.
Also, clean up the jobfile code so that it is more debuggable.
Make them easier to express by only having the cxx_type parameter which
has the full namespace name, and drop the cxx_namespace thing.
Add support for multiple levels of namespace.
Since the early days of M5, an event needed to know which event queue
it was on, and that data was required at the time of construction of
the event object. In the future parallelized M5, this sort of
requirement does not work well since the proper event queue will not
always be known at the time of construction of an event. Now, events
are created, and the EventQueue itself has the schedule function,
e.g. eventq->schedule(event, when). To simplify the syntax, I created
a class called EventManager which holds a pointer to an EventQueue and
provides the schedule interface that is a proxy for the EventQueue.
The intent is that objects that frequently schedule events can be
derived from EventManager and then they have the schedule interface.
SimObject and Port are examples of objects that will become
EventManagers. The end result is that any SimObject can just call
schedule(event, when) and it will just call that SimObject's
eventq->schedule function. Of course, some objects may have more than
one EventQueue, so this interface might not be perfect for those, but
they should be relatively few.
I've done a few things here. First, I invoke the script a little bit
differently so that pdb doesn't get confused. Second, I've stored the
actual filename in the module's __file__ so that pdb can find the
source file on your machine.
Targets look like libm5_debug.so. This target can be dynamically
linked into another C++ program and provide just about all of the M5
features. Additionally, this library is a standalone module that can
be imported into python with an "import libm5_debug" type command
line.
I forgot to do this when I renamed everything else.

Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off. Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.
We should always refer to the specific ISA in that arch directory.
This is especially necessary if we're ever going to make it to the
point where we actually have heterogeneous systems.
