Kevin Lim 941d3168d0 Updates for commit. 
1. Move interrupt handling to a separate function to clean up main commit() function a bit.  Also gate the function call off properly based on whether or not there are outstanding interrupts, and the system is not in PAL mode.
2. Better handling of updating instruction's status bits.  Instructions are not marked "atCommit" until other stages view it (pushed off to IEW/IQ), and they have been properly handled (faults).
3. Don't consider the ROB "empty" for the purpose of other stages until the ROB is empty, all stores have written back, and there was no store commits this cycle.  The last is necessary in case a store committed, in which case it would look like all stores have written back but in actuality have not.

src/cpu/o3/commit.hh:
    Slightly modify how interrupts are handled.  Also include some extra bools to keep track of state properly.
src/cpu/o3/commit_impl.hh:
    Slightly modify how interrupts are handled.  Also include some extra bools to keep track of state.

    General correctness updates, most specifically for when commit broadcasts to other stages that the ROB is empty.

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.
