From 51647e7bec8e8607fc5713b4ace2c24ce8a7455a Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Thu, 23 Feb 2006 17:00:29 -0500 Subject: 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 --- cpu/SConscript | 99 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 99 insertions(+) create mode 100644 cpu/SConscript (limited to 'cpu/SConscript') diff --git a/cpu/SConscript b/cpu/SConscript new file mode 100644 index 000000000..dbe174660 --- /dev/null +++ b/cpu/SConscript @@ -0,0 +1,99 @@ +# -*- mode:python -*- + +# Copyright (c) 2006 The Regents of The University of Michigan +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions are +# met: redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer; +# redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution; +# neither the name of the copyright holders nor the names of its +# contributors may be used to endorse or promote products derived from +# this software without specific prior written permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.
