80d9be86e6 gcc: Add extra parens to quell warnings.
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.

6efb930e19 gcc: Version 4.3 is pretty anal about shadowing types, placate it.
In the future, it would be nice to put the O3CPU into its own
namespace so that we don't end up hardcoding pointers to the global
namespace.

ce3d8c2b03 atomicio: provide atomic read and write functions.
These functions keep trying to read and write until all data has been
transferred, or an error occurrs.  In the case where an end of file
hasn't been reached, but all of the bytes have not been read/written,
try again.  On EINTR, try again.

f066db7fcd inifile: Whack preprocessor access.
We haven't used the preprocessor feature of the inifile stuff in a
very long time, so let's get rid of it since it would otherwise take
effort to maintain.

fe8aeff362 Add -r/-e options to redirect stdout/stderr.
Better than using shell since it automatically uses -d directory
for output files (creating it as needed).

50ef39af82 sockets: Add a function to disable all listening sockets.
When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb.  Expose a function to disable those ports, and have the
regression scripts disable them.  There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.

c5fbbf376a Change everything to use the cached virtPort rather than created their own each time.
This appears to work, but I don't want to commit it until it gets tested a lot more.
I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.

f6e5b92d63 ELF Loader: Use physical addresses instead of virtual ones.
This works in SE mode because the virtual and physical addresses specified for
segments are the same. In Alpha, the LoadAddrMask is still necessary because
the virtual and physical addresses are the same and apparently rely on the
super page mechanism. All of the regressions pass.

e8ace88e89 create base/fenv.c to standerdize fenv across platforms. It's a c file and not a cpp file because c99
(which defines fenv) doesn't necessarily extend to c++ and it is a problem with solaris. If really
desired this could wrap the ieeefp interface found in bsd* as well, but I see no need at the moment.

a575fbd4aa Completely re-work how the scons framework incorporates swig
and python code into m5 to allow swig an python code to
easily added by any SConscript instead of just the one in
src/python.  This provides SwigSource and PySource for
adding new files to m5 (similar to Source for C++).  Also
provides SimObject for including files that contain SimObject
information and build the m5.objects __init__.py file.

1aef5c06a3 Rework the way SCons recurses into subdirectories, making it
automatic.  The point is that now a subdirectory can be added
to the build process just by creating a SConscript file in it.
The process has two passes.  On the first pass, all subdirs
of the root of the tree are searched for SConsopts files.
These files contain any command line options that ought to be
added for a particular subdirectory.  On the second pass,
all subdirs of the src directory are searched for SConscript
files.  These files describe how to build any given subdirectory.
I have added a Source() function.  Any file (relative to the
directory in which the SConscript resides) passed to that
function is added to the build.  Clean up everything to take
advantage of Source().
function is added to the list of files to be built.

d55b25cde6 Move all of the parameters of the Root SimObject so they are

core.(cc|hh) since it really belogs there now.
In the process, simplify how ticks are used in the python code.

29e5df890d Make trap instructions always generate TrapInstruction Fault objects which call into the Process object to handle system calls. Refactored the Process objects, and move the handler code into it's own file, and add some syscalls which are used in a natively compiled hello world. Software traps with trap number 3 (not syscall number 3) are supposed to cause the register windows to be flushed but are ignored right now. Finally, made uname for SPARC report a 2.6.12 kernel which is what m22-018.pool happens to be running.
