Enable building only selected CPU models via new scons
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.
