baca1f0566 isa_parser: Turn the ISA Parser into a subclass of Grammar. 
This is to prepare for future cleanup where we allow SCons to create a
separate grammar class for each ISA

2278363015 slicc: Pure python implementation of slicc. 
This is simply a translation of the C++ slicc into python with very minimal
reorganization of the code.  The output can be verified as nearly identical
by doing a "diff -wBur".

Slicc can easily be run manually by using util/slicc

9a8cb7db7e python: Move more code into m5.util allow SCons to use that code. 
Get rid of misc.py and just stick misc things in __init__.py
Move utility functions out of SCons files and into m5.util
Move utility type stuff from m5/__init__.py to m5/util/__init__.py
Remove buildEnv from m5 and allow access only from m5.defines
Rename AddToPath to addToPath while we're moving it to m5.util
Rename read_command to readCommand while we're moving it
Rename compare_versions to compareVersions while we're moving it.

6e97feb8a5 X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc. 
The manuals from both AMD and Intel say that when writing to a 32 bit
destination in 64 bit mode, the upper 32 bits of the register are filled with
zeros. They also both say that the CMOV instructions leave their destination
alone when their condition fails. Unfortunately, it seems that CMOV will zero
extend its destination register whether or not it was supposed to actually do
a move on both platforms. This seems to be the only case where this happens,
but it would be hard to say for sure.

3a55fc5cac X86: Implement shift right/left double microops. 
This is my best guess as far as what these should do. Other existing microops
use implicit registers, mul1s and mul1u for instance, so this should be ok.
The microop that loads the implicit DoubleBits register would fall into one
of the microop slots for moving to/from special registers.

33b28fde7a slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers 
This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.

c0755e6085 Rename internal Request fields to start with '_'.

This is also a first step to switching the accessors over to
our new "standard", e.g., getVaddr() -> vaddr().
