From b13e28afbb0f4bd5ce064339fb527bd5c6b1029c Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Fri, 2 Jul 2004 21:16:38 -0700 Subject: Initial SCons-based build system. See www.scons.org. 'cd build; scons' will build ALPHA/m5.debug. Use e.g. 'scons KERNEL/m5.opt' to build other binaries. Read the comments in build/SConstruct for more details. base/traceflags.py: Take basename of generated cc/hh files from command line instead of hardwiring them. Lets us call the script from a different directory and still have the files end up in the right place (e.g. "base/traceflags.py base/traceflags"). --HG-- extra : convert_revision : ee4dbb59040cf07590929275f6c1c01e8d4e00b4 --- SConscript | 384 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 384 insertions(+) create mode 100644 SConscript (limited to 'SConscript') diff --git a/SConscript b/SConscript new file mode 100644 index 000000000..7d8d9f50e --- /dev/null +++ b/SConscript @@ -0,0 +1,384 @@ +# -*- mode:python -*- + +# Copyright (c) 2004 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.
