# SCons top-level build description (SConstruct) file.
#
# To build M5, you need a directory with three things:
# 1. A copy of this file (named SConstruct).
# 2. A link named 'm5' to the top of the M5 simulator source tree.
# 3. A link named 'ext' to the top of the M5 external source tree.
#
# Then type 'scons' to build the default configuration (see below), or
# 'scons <CONFIG>/<binary>' to build some other configuration (e.g.,
# 'ALPHA_FS/m5.opt' for the optimized full-system version).

# Define Configurations
#
# The build system infers the build options from the subdirectory name
# that the simulator is built under. The subdirectory name must be of
# the form <CONFIG>[.<OPT>]*, where <CONFIG> is a base configuration
# (e.g., ALPHA_SE or ALPHA_FS) and OPT is an option (e.g., MYSQL). The
# following code defines the standard configurations and options.
# Additional local configurations and options are read from the file
# 'local_configs' if it exists.
#
# Each base configuration or option is defined in two steps: a
# function that takes an SCons build environment and modifies it
# appropriately for that config or option, and an entry in the
# 'configs_map' or 'options_map' dictionary that maps the directory
# name string to the function. (The directory names are all upper
# case, by convention.)

# Figure out which configurations to set up.
#
#
# It's prohibitive to do all the combinations of base configurations
# and options, so we have to infer which ones the user wants.
#
# 1. If there are command-line targets, the configuration(s) are inferred
# from the directories of those targets. If scons was invoked from a
# subdirectory (using 'scons -u'), those targets have to be
# interpreted relative to that subdirectory.
#
# 2. If there are no command-line targets, and scons was invoked from a
# subdirectory (using 'scons -u'), the configuration is inferred from
# the name of the subdirectory.
#
# 3. If there are no command-line targets and scons was invoked from
# the root build directory, a default configuration is used. The
# built-in default is ALPHA_SE, but this can be overridden by setting the
# M5_DEFAULT_CONFIG shell environment veriable.
#
# In cases 2 & 3, the specific file target defaults to 'm5.debug', but
# this can be overridden by setting the M5_DEFAULT_BINARY shell
# environment veriable.
