CPU_MODELS parameter. For example:
scons CPU_MODELS="SimpleCPU,FullCPU" ALPHA_SE/m5.debug
Unfortunately the option is not sticky due to a scons
bug with saving & restoring ListOption parameters.
SConscript:
Separate out cpu-model-specific files so they can be conditionally
included based on value of new CPU_MODELS parameter.
Most of these are now handled in cpu/SConscript, except for FullCPU
which is still in this file.
arch/SConscript:
The set of CPU-model-specific execute files must now be
determined from the CPU_MODELS parameter, via the new
cpu_models.py file.
Also pass the list of configured CPU models to isa_parser.py.
arch/isa_parser.py:
Move CpuModel definition and objects out to a
separate file so they can be shared with scons.
Global list of CPU models to generate code for is now
controlled by command-line parameters (so we can do
only a subset of the available ones).
build/SConstruct:
Define new CPU_MODELS ListOption.
cpu/static_inst.hh:
Rename static_inst_impl.hh to static_inst_exec_sigs.hh.

Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile.
arch/alpha/alpha_memory.cc:
The regfile has been changed so it no longer has the opcode and ra. Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA().
arch/alpha/ev5.cc:
Moved code that once existed within simpleCPU to ev5, and templatized it.
This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code.
Also moved ISA specific zero registers from simpleCPU to here.

Added in FastCPUExecContext so it will generate code for the FastCPU model as well.
cpu/exec_context.cc:
Added in a more generic trap function so "ev5_trap" doesn't need to be called. It currently still calls the old method, with plans for making this ISA dependent in the future.
cpu/exec_context.hh:
Exec context now has the instruction within it. Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed.
Also has declaration for more generic trap() function.
cpu/simple_cpu/simple_cpu.cc:
Removed references to opcode and ra, and instead sets the xc's instruction with the fetched instruction.
cpu/static_inst.hh:
Added declaration for execute() using FastCPUExecContext.

with an IsNonSpeculative flag.
No effect on results of non-full-system or SimpleCPU.
Very small impact on full-system FullCPU runs since old wrong-path
call_pal insts used to change the PC, where now they're treated
as no-ops.
arch/alpha/isa_desc:
Get rid of xc->misspeculating() checks, use IsNonSpeculative flag instead.
cpu/static_inst.hh:
Add IsNonSpeculative flag and isNonSpeculative() method to test it.

out CPU model. ISA description now generates multiple
output source files to (in theory) reduce compilation time.
arch/alpha/isa_desc:
Update for parser changes. Move most constructors
out of class declarations (which are now in decoder.hh)
and into decoder.cc. Move all execute() methods into
exec output.
arch/isa_parser.py:
Significant changes to make ISA description completely
independent of CPU model, and isolate model-dependent parts
of parser into one little class (CpuModel). Also split up code
output into multiple files (a header, a main source file, and
per-cpu execute() method files).
Noticeable changes to language as a result. See updated Doxygen
documentation.
cpu/simple_cpu/simple_cpu.hh:
SimpleCPUExecContext typedef no longer needed.
Add forward declaration of Process.
cpu/static_inst.hh:
SimpleCPUExecContext and FullCPUExecContext typedefs no longer needed.
Make eaCompInst() and memAccInst() return const refs.

(Still not perfect though.)
arch/alpha/isa_desc:
Do a better job of factoring out CPU model. (Still not perfect though.)
Pull execute() methods out of class declarations into separate section
of file, allowing (1) easier replication for different CPU models and
(2) a path to putting them all in a separate file. Force all instruction
execution context into a single model-dependent class (SimpleCPU itself
for SimpleCPU, DynInst for FullCPU).
arch/isa_parser.py:
Do a better job of factoring out CPU model. (Still not perfect though.)
Pull execute() methods out of class declarations into separate section
of file, allowing (1) easier replication for different CPU models and
(2) a path to putting them all in a separate file.
Also restructure top level to allow parser to run under interactive
interpreter session for easier debugging.
cpu/exec_context.hh:
Add a few new methods to clean up isa_desc.
cpu/simple_cpu/simple_cpu.cc:
cpu/static_inst.hh:
StaticInst::execute no longer takes a CPU and an ExecContext,
just a unified FooCPUExecContext.
cpu/simple_cpu/simple_cpu.hh:
Add methods to redirect calls to ExecContext so SimpleCPU
can act as sole instruction execution context for itself.
Typedef SimpleCPU to SimpleCPUExecContext.

execution pipeline (Alpha trapb & excb).
Add support for write memory barriers (mostly impacts
store buffer).
Add StaticInst flag to indicate memory barriers, though
this is not modeled in the pipeline yet.
arch/alpha/isa_desc:
Implement trapb, excb, mb, and wmb as insts with
no execution effect (empty execute() function) but
with flags that indicate their side effects.
Also make sure every instruction that needs to go to
the execute stage has a real opClass value, since we
are now using No_OpClass to signal insts that can get
dropped at dispatch.
StaticInst::branchTarget() is now a const method.
cpu/static_inst.hh:
Add flags to indicate serializing insts (trapb, excb) and
memory and write barriers.
Also declare some StaticInst methods as const methods.
