5639fb2c43 Fix memory leak.
src/arch/alpha/ev5.cc:
    Fix memory leak.  The faults are refcounted, but that only works if you're actually assigning them to a RefCountingPtr.

3e1537cf8b Removed syscall function from thread_context.hh. ThreadContext is the interface for external, non-CPU objects to access the thread, so they probably shouldn't be able to call syscall(). The case it was being used for was already handled by the ISA code.

babb22eea4 Fix python binary name in arch/SConscript.
Also delete no-longer-needed SPARC test.py files (should
have gone with my last chnageset where LiveProcess
became ISA-independent).

src/arch/SConscript:
    Mistakenly committed hard-coded python binary name.
    Should use same python to run isa_parser that was
    used to run scons.

39f85a1de4 Only allow SimObject classes to be instantiated (no cloning!).
Provide a makeClass() method to generate a new class using
a SimObject instance as a template.
All instantiation, subclassing, and class generation is done
recursively using "deep copy"-style memoization to maintain
object relationships in the face of multiple references to
shared objects/classes.

src/python/m5/multidict.py:
    Rename local dict attribute from 'dict' to 'local'
    for clarity.

29e34a739b Move main control from C++ into Python.
User script now invokes initialization and
simulation loop after building configuration.
These functions are exported from C++ to Python
using SWIG.

SConstruct:
    Set up SWIG builder & scanner.
    Set up symlinking of source files into build directory
    (by not disabling the default behavior).
configs/test/test.py:
    Rewrite to use new script-driven interface.
    Include a sample option.
src/SConscript:
    Set up symlinking of source files into build directory
    (by not disabling the default behavior).
    Add SWIG-generated main_wrap.cc to source list.

src/python/SConscript:
    Add SWIG build command for main.i.
    Use python/m5 in build dir as source for zip archive...
    easy now with file duplication enabled.
src/python/m5/__init__.py:
    - Move copyright notice back to C++ so we can print
    it right away, even for interactive sessions.
    - Get rid of argument parsing code; just provide default
    option descriptors for user script to call optparse with.
    - Don't clutter m5 namespace by sucking in all of m5.config
    and m5.objects.
    - Move instantiate() function here from config.py.
src/python/m5/config.py:
    - Move instantiate() function to __init__.py.

src/sim/eventq.cc:
src/sim/eventq.hh:
    Support for Python-called simulate() function:
    - Use IsExitEvent flag to signal events that want
    to exit the simulation loop gracefully (instead of
    calling exit() to terminate the process).
    - Modify interface to hand exit event object back to
    caller so it can be inspected for cause.
src/sim/host.hh:
    Add MaxTick constant.
src/sim/main.cc:
    Move copyright notice back to C++ so we can print
    it right away, even for interactive sessions.
    Use PYTHONPATH environment var to set module path
    (instead of clunky code injection method).
    Move main control from here into Python:
    - Separate initialization code and simulation loop
    into separate functions callable from Python.
    - Make Python interpreter invocation more pure (more
    like directly invoking interpreter).
    Add -i and -p flags (only options on binary itself;
    other options processed by Python).
    Import readline package when using interactive mode.
src/sim/sim_events.cc:
    SimExitEvent is now SimLoopExitEvent, and uses
    IsSimExit flag to terminate loop (instead of
    exiting simulator process).
src/sim/sim_events.hh:
    SimExitEvent is now SimLoopExitEvent, and uses
    IsSimExit flag to terminate loop (instead of
    exiting simulator process).
    Get rid of a few unused constructors.
src/sim/sim_exit.hh:
    SimExit() is now exitSimLoop().
    Get rid of unused functions.
    Add comments.

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/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.
src/cpu/simple_thread.cc:
    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.
