Kevin Lim e21878c3f2 Handle status bits a little better, as well as non-speculative instructions. 
src/cpu/o3/iew_impl.hh:
    Allow for slightly more flexible handling of non-speculative instructions.  They can be other classes now, such as loads or stores.

    Also be sure to clear the state associated with squashes that are not used.  i.e. if a squash due to a memory ordering violation happens on the same cycle as an older branch squashing, clear the state associated with the memory ordering violation.

    Lastly don't consider uncached loads to officially be "at commit" until IEW receives the signal back from commit about the load.
src/cpu/o3/inst_queue_impl.hh:
    Don't consider non-speculative instructions to be "at commit" until the IQ has received a signal from commit about the instruction.  This prevents non-speculative instructions from being issued too early.
src/cpu/o3/mem_dep_unit_impl.hh:
    Clear instruction's ability to issue if it's replayed.

README 

This is release 2.0_beta (patch 1) of 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 0.96.91 or newer, get it from
http://wwww.scons.org.

2. If you don't have SWIG version 1.3.28 or newer, get it from
http://wwww.swig.org.

3. 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: 
   - src: source code of the m5 simulator
   - tests: regression tests
   - ext: less-common external packages needed to build m5
   - system/alpha: source for Alpha console and PALcode

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

M5 supports 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-dev@eecs.umich.edu.
