a14013af3a CPU: Unify initMemProxies across CPUs and simulation modes
This patch unifies where initMemProxies is called, in the init()
method of each BaseCPU subclass, before TheISA::initCPU is
called. Moreover, it also ensures that initMemProxies is called in
both full-system and syscall-emulation mode, thus unifying also across
the modes. An additional check is added in the ThreadState to ensure
that initMemProxies is only called once.

72538294fb gcc: Clean-up of non-C++0x compliant code, first steps
This patch cleans up a number of minor issues aiming to get closer to
compliance with the C++0x standard as interpreted by gcc and clang
(compile with std=c++0x and -pedantic-errors). In particular, the
patch cleans up enums where the last item was succeded by a comma,
namespaces closed by a curcly brace followed by a semi-colon, and the
use of the GNU-extension typeof (replaced by templated functions). It
does not address variable-length arrays, zero-size arrays, anonymous
structs, range expressions in switch statements, and the use of long
long. The generated CPU code also has a large number of issues that
remain to be fixed, mainly related to overflows in implicit constant
conversion (due to shifts).

9e3c8de30b MEM: Make port proxies use references rather than pointers
This patch is adding a clearer design intent to all objects that would
not be complete without a port proxy by making the proxies members
rathen than dynamically allocated. In essence, if NULL would not be a
valid value for the proxy, then we avoid using a pointer to make this
clear.

The same approach is used for the methods using these proxies, such as
loadSections, that now use references rather than pointers to better
reflect the fact that NULL would not be an acceptable value (in fact
the code would break and that is how this patch started out).

Overall the concept of "using a reference to express unconditional
composition where a NULL pointer is never valid" could be done on a
much broader scale throughout the code base, but for now it is only
done in the locations affected by the proxies.

4fdecae443 Thread: Use inherited baseCpu rather than cpu in SimpleThread
This patch is a trivial simplification, removing the cpu pointer from
SimpleThread and relying on the baseCpu pointer in ThreadState. The
patch does not add or change any functionality, it merely cleans up
the code.

f85286b3de MEM: Add port proxies instead of non-structural ports
Port proxies are used to replace non-structural ports, and thus enable
all ports in the system to correspond to a structural entity. This has
the advantage of accessing memory through the normal memory subsystem
and thus allowing any constellation of distributed memories, address
maps, etc. Most accesses are done through the "system port" that is
used for loading binaries, debugging etc. For the entities that belong
to the CPU, e.g. threads and thread contexts, they wrap the CPU data
port in a port proxy.

The following replacements are made:
FunctionalPort      > PortProxy
TranslatingPort     > SETranslatingPortProxy
VirtualPort         > FSTranslatingPortProxy

7617dcf736 ThreadState: initialize status to Halted in constructor.
This provides a common initial status for all threads independent
of CPU model (unlike the prior situation where CPUs initialized
threads to inconsistent states).
This mostly matters for SE mode; in FS mode, ISA-specific startupCPU()
methods generally handle boot-time initialization of thread contexts
(since the right thing to do is ISA-dependent).

d857faf073 Add in Context IDs to the simulator. From now on, cpuId is almost never used,
the primary identifier for a hardware context should be contextId().  The
concept of threads within a CPU remains, in the form of threadId() because
sometimes you need to know which context within a cpu to manipulate.

c55a467a06 make BaseCPU the provider of _cpuId, and cpuId() instead of being scattered
across the subclasses. generally make it so that member data is _cpuId and
accessor functions are cpuId(). The ID val comes from the python (default -1 if
none provided), and if it is -1, the index of cpuList will be given. this has
passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard
switch.

c96160cef5 Change the connecting of the physPort and virtPort to the memory object below the CPU to happen every time activateContext is called. The overhead is probably a little higher than necessary, but allows these connections to properly be made when there are CPUs that are inactive until they are switched in.
Right now this introduces a minor memory leak as old physPorts and virtPorts are not deleted when new ones are created.  A flyspray task has been created for this issue.  It can not be resolved until we determine how the bus will handle giving out ID's to functional ports that may be deleted.

src/cpu/o3/cpu.cc:
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    Change the setup of the physPort and virtPort to instead happen every time the CPU has a context activated.  This is a little high overhead, but keeps it working correctly when the CPU does not have a physical memory attached to it until it switches in (like the case of switch CPUs).
src/cpu/o3/thread_context.hh:
    Change function from being called at init() to just being called whenever the memory ports need to be connected.
src/cpu/o3/thread_context_impl.hh:
    Update this to not delete the port if it's the same as the virtPort.
src/cpu/thread_context.hh:
    Change function from being called at init() to whenever the memory ports need to be connected.
src/cpu/thread_state.cc:
    Instead of initializing the ports, simply connect them, deleting any old ports that might exist.  This allows these functions to be called multiple times.
src/cpu/thread_state.hh:
    Ports are no longer initialized, but rather connected at context activation time.

54d4220b00 Reorganization/renaming of CPUExecContext. Now it is called SimpleThread in order to clear up the confusion due to the many ExecContexts. It also derives from a common ThreadState object, which holds various state common to threads across CPU models.
Following with the previous check-in, ExecContext now refers only to the interface provided to the ISA in order to access CPU state.  ThreadContext refers to the interface provided to all objects outside the CPU in order to access thread state.  SimpleThread provides all thread state and the interface to access it, and is suitable for simple execution models such as the SimpleCPU.

src/cpu/o3/alpha_cpu_impl.hh:

src/cpu/o3/thread_state.hh:

src/cpu/ozone/thread_state.hh:
    Rename CPUExecContext to SimpleThread, move a lot of common code into base ThreadState class.
src/cpu/thread_state.hh:
    Push a lot of common code into base ThreadState class.  This goes along with renaming CPUExecContext to SimpleThread, and making it derive from ThreadState.

    Rename CPUExecContext to SimpleThread, make it derive from ThreadState.  This helps push a lot of common code/state into a single class that can be used by all CPUs.

    Rename CPUExecContext to SimpleThread, make it derive from ThreadState.

eb0e416998 Change ExecContext to ThreadContext. This is being renamed to differentiate between the interface used objects outside of the CPU, and the interface used by the ISA. ThreadContext is used by objects outside of the CPU and is specifically defined in thread_context.hh. ExecContext is more implicit, and is defined by files such as base_dyn_inst.hh or cpu/simple/base.hh.
Further renames/reorganization will be coming shortly; what is currently CPUExecContext (the old ExecContext from m5) will be renamed to SimpleThread or something similar.
