From 1aef5c06a3702d7722dcd38e342eae950839cecb Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Sat, 10 Mar 2007 23:00:54 -0800 Subject: Rework the way SCons recurses into subdirectories, making it automatic. The point is that now a subdirectory can be added to the build process just by creating a SConscript file in it. The process has two passes. On the first pass, all subdirs of the root of the tree are searched for SConsopts files. These files contain any command line options that ought to be added for a particular subdirectory. On the second pass, all subdirs of the src directory are searched for SConscript files. These files describe how to build any given subdirectory. I have added a Source() function. Any file (relative to the directory in which the SConscript resides) passed to that function is added to the build. Clean up everything to take advantage of Source(). function is added to the list of files to be built. --HG-- extra : convert_revision : 103f6b490d2eb224436688c89cdc015211c4fd30 --- src/dev/SConscript | 74 +++++++++++++++++------------------------------- src/dev/alpha/SConscript | 43 +++++----------------------- src/dev/sparc/SConscript | 24 ++++------------ 3 files changed, 39 insertions(+), 102 deletions(-) (limited to 'src/dev') diff --git a/src/dev/SConscript b/src/dev/SConscript index 951bc29d1..1ec83de4b 100644 --- a/src/dev/SConscript +++ b/src/dev/SConscript @@ -29,51 +29,29 @@ # Authors: Steve Reinhardt # Gabe Black -import os.path, sys - -# Import build environment variable from SConstruct. -Import('env') - -# Right now there are no source files immediately in this directory -sources = [] - -# -# Now include other ISA-specific sources from the ISA subdirectories. -# - -isa = env['TARGET_ISA'] # someday this may be a list of ISAs - -# -# These source files can be used by any architecture -# - -sources += Split(''' - baddev.cc - disk_image.cc - etherbus.cc - etherdump.cc - etherint.cc - etherlink.cc - etherpkt.cc - ethertap.cc - ide_ctrl.cc - ide_disk.cc - io_device.cc - isa_fake.cc - ns_gige.cc - pciconfigall.cc - pcidev.cc - pktfifo.cc - platform.cc - simconsole.cc - simple_disk.cc - ''') - -# Let the target architecture define what additional sources it needs -sources += SConscript(os.path.join(isa, 'SConscript'), exports = 'env') - -# Convert file names to SCons File objects.
