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/alpha/SConscript | 101 ++++++++++++++++------------------------------ src/arch/alpha/SConsopts | 37 +++++++++++++++++ 2 files changed, 72 insertions(+), 66 deletions(-) create mode 100644 src/arch/alpha/SConsopts (limited to 'src/arch/alpha') diff --git a/src/arch/alpha/SConscript b/src/arch/alpha/SConscript index addd49884..61611e9f6 100644 --- a/src/arch/alpha/SConscript +++ b/src/arch/alpha/SConscript @@ -29,76 +29,45 @@ # Authors: Gabe Black # Steve Reinhardt -import os -import sys -from os.path import isdir +Import('*') -# This file defines how to build a particular configuration of M5 -# based on variable settings in the 'env' build environment. +if env['TARGET_ISA'] == 'alpha': + Source('faults.cc') + Source('floatregfile.cc') + Source('intregfile.cc') + Source('miscregfile.cc') + Source('regfile.cc') + Source('remote_gdb.cc') -# Import build environment variable from SConstruct. -Import('env') + if env['FULL_SYSTEM']: + Source('arguments.cc') + Source('ev5.cc') + Source('idle_event.cc') + Source('ipr.cc') + Source('kernel_stats.cc') + Source('osfpal.cc') + Source('pagetable.cc') + Source('stacktrace.cc') + Source('system.cc') + Source('tlb.cc') + Source('vtophys.cc') -################################################### -# -# Define needed sources. -# -################################################### - -# Base sources used by all configurations. -base_sources = Split(''' - faults.cc - floatregfile.cc - intregfile.cc - miscregfile.cc - regfile.cc - remote_gdb.cc - ''') - -# Full-system sources -full_system_sources = Split(''' - arguments.cc - ev5.cc - freebsd/system.cc - idle_event.cc - ipr.cc - kernel_stats.cc - linux/system.cc - osfpal.cc - pagetable.cc - stacktrace.cc - system.cc - tlb.cc - tru64/system.cc - vtophys.cc - ''') - - -# Syscall emulation (non-full-system) sources -syscall_emulation_sources = Split(''' - linux/linux.cc - linux/process.cc - tru64/tru64.cc - tru64/process.cc - process.cc - ''') - -# Set up complete list of sources based on configuration. -sources = base_sources + Source('freebsd/system.cc') + Source('linux/system.cc') + Source('tru64/system.cc') -if env['FULL_SYSTEM']: - sources += full_system_sources -else: - sources += syscall_emulation_sources + else: + Source('process.cc') -# Convert file names to SCons File objects.
