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. --HG-- extra : convert_revision : 163df32a76d4c05900490b2bce4c7962a5e3f614
