38aa50bb49 base: disable FastAlloc in debug builds by default
FastAlloc's reuse policies can mask allocation bugs, so
we typically want it disabled when debugging.  Set
FORCE_FAST_ALLOC to enable even when debugging, and set
NO_FAST_ALLOC to disable even in non-debug builds.

02f10fbdc8 SCons: Stop embedding the mercurial revision into the binary.
This causes a lot of rebuilds that could have otherwise possibly been
avoided, and, more annoyingly, a lot of unnecessary rerunning of the
regressions. The benefits of having the revision in the output haven't
materialized, so this change removes it.

9e608a6ad7 SCons: Separately label the global non-sticky options.
The global sticky options were being printed with a heading, and then the
global nonsticky options were being printed immediately after them without a
heading. Because the two lists ran together and the first had its own heading,
it looked like -all- those options where sticky even though some of them
aren't. This change adds a label to the second list so it's clear they're
different.

3c8cc170d2 style: clean up style hook code a bit
I've renamed the check_whitespace operation to check_style.  You're going to
need to change your .hg/hgrc file.  While you're at it, add a pre-qrefresh
hook please.

d650f4138e scons: show sources and targets when building, and colorize output.
I like the brevity of Ali's recent change, but the ambiguity of
sometimes showing the source and sometimes the target is a little
confusing.  This patch makes scons typically list all sources and
all targets for each action, with the common path prefix factored
out for brevity.  It's a little more verbose now but also more
informative.

Somehow Ali talked me into adding colors too, which is a whole
'nother story.

fe6574ecc0 style: make style hook work with pre-qrefresh and update to use new code
clean up the code a little bit while we're at it.

I recommend that everyone adds the pre-qrefresh hook below since it
will make qref run the style hook and not just commit/qpush

style = <m5 path>/util/style.py

pretxncommit.style = python:style.check_whitespace

de904a6d39 SCons: Make --help reflect the arguments to scons.
The arguments were added to the global_sticky_vars Variables object after the
basic help text was generated. As a result, the "actual:" value wouldn't
reflect the arguments to scons and wouldn't really be the "actual" value used
by the build. This change fixes that by updating global_sticky_vars slightly
earlier.

7311fd7182 ruby: Migrate all of ruby and slicc to SCons.
Add the PROTOCOL sticky option sets the coherence protocol that slicc
will parse and therefore ruby will use.  This whole process was made
difficult by the fact that the set of files that are output by slicc
are not easily known ahead of time.  The easiest thing wound up being
to write a parser for slicc that would tell me.  Incidentally this
means we now have a slicc grammar written in python.

dc35d2f125 scons: re-work the *Source functions to take more information.
Start by turning all of the *Source functions into classes
so we can do more calculations and more easily collect the data we need.
Add parameters to the new classes for indicating what sorts of flags the
objects should be compiled with so we can allow certain files to be compiled
without Werror for example.

05d8c9acb8 scons: Rename the basic environment from env -> main.
env is used as a local variable all over the place and sometimes it is
easy to get confused as to whether the global env or local env is being
used.  This will become especially important when I change the way we
support our variants.

56e5509bfd scons: Fix two problems with the way that the library path is generated.
1) -L is automatically added, so don't do it ourselves
2) prepend the paths for gzstream and libelf so they are certain to
come first. The problem is that python might add /usr/lib to the path
and the user might have a locally installed version of libelf installed.

dd6ea8797f scons: Require SCons version 0.98.1
This allows me to clean things up so we are up to date with respect to
deprecated features.  There are many features scheduled for permanent failure
in scons 2.0 and 0.98.1 provides the most compatability for that.  It
also paves the way for some nice new features that I will add soon

3087be945d Output: Include gzstream package to allow automatically-gzipped output
The gzstream package provides an ostream-interface for writing gzipped files.
The package comes from:
    http://www.cs.unc.edu/Research/compgeom/gzstream/
And is distributed under the LGPL license. Both the license and version
information has been preservered, though all other files in the package have
been purged. Minor modifications to the code have been made. The output module
detects when a filename ends in .gz and constructs an ogzstream object instead
of an ofstream object. This works for both the create(...) and find(...)
commands. Additionally, since gzstream objects needs to be closed to ensure
proper file termination, I have the output deconstructor deleting all ostream's
that it manages on behalf of find(...). At the moment, the only output file
that I know this functionality works for is stats, i.e. by specifying
"--stats-file=m5stats.txt.gz" on the command line.

4d64d7664c SCons: Allow top level directory of EXTRAS able to contain SConscripts.
The current EXTRAS will fail if the top level directory pointed to by EXTRAS
has a SConscript file in it.  We allow this by including the directory name
of the EXTRA in the build directory which prevents a clash between
src/SConscript and extra/SConscript. Maintain compatibility with older uses
of EXTRAS by adding a -I for each top level extra directory.

ede89c2d54 libm5: Create a libm5 static library for embedding m5.
This should allow m5 to be more easily embedded into other simulators.
The m5 binary adds a simple main function which then calls into the m5
libarary to start the simulation. In order to make this work
correctly, it was necessary embed python code directly into the
library instead of the zipfile hack.  This is because you can't just
append the zipfile to the end of a library the way you can a binary.
As a result, Python files that are part of the m5 simulator are now
compile, marshalled, compressed, and then inserted into the library's
data section with a certain symbol name.  Additionally, a new Importer
was needed to allow python to get at the embedded python code.

Small additional changes include:
- Get rid of the PYTHONHOME stuff since I don't think anyone ever used
it, and it just confuses things.  Easy enough to add back if I'm wrong.
- Create a few new functions that are key to initializing and running
the simulator: initSignals, initM5Python, m5Main.

The original code for creating libm5 was inspired by a patch Michael
Adler, though the code here was done by me.
