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/arch/SConscript | 23 ++++------------------- 1 file changed, 4 insertions(+), 19 deletions(-) (limited to 'src/arch/SConscript') diff --git a/src/arch/SConscript b/src/arch/SConscript index 74be5f8d1..c3ff69f46 100644 --- a/src/arch/SConscript +++ b/src/arch/SConscript @@ -28,13 +28,9 @@ # # Authors: Steve Reinhardt -import os.path, sys +import sys -# Import build environment variable from SConstruct. -Import('env') - -# Right now there are no source files immediately in this directory -sources = [] +Import('*') ################################################################# # @@ -66,7 +62,7 @@ isa_switch_hdrs = Split(''' ''') # Set up this directory to support switching headers -env.make_switching_dir('arch', isa_switch_hdrs, env) +make_switching_dir('arch', isa_switch_hdrs, env) ################################################################# # @@ -100,7 +96,7 @@ execfile(cpu_models_file.srcnode().abspath) # Several files are generated from the ISA description. # We always get the basic decoder and header file. -isa_desc_gen_files = Split('decoder.cc decoder.hh') +isa_desc_gen_files = [ 'decoder.cc', 'decoder.hh' ] # We also get an execute file for each selected CPU model. isa_desc_gen_files += [CpuModel.dict[cpu].filename for cpu in env['CPU_MODELS']] @@ -128,14 +124,3 @@ else: emitter = isa_desc_emitter) env.Append(BUILDERS = { 'ISADesc' : isa_desc_builder }) - -# -# Now include other ISA-specific sources from the ISA subdirectories. -# - -isa = env['TARGET_ISA'] # someday this may be a list of ISAs - -# Let the target architecture define what additional sources it needs -sources += SConscript(os.path.join(isa, 'SConscript'), exports = 'env') - -Return('sources') -- cgit v1.2.3
