New directory structure:

- simulator source now in 'src' subdirectory - imported files from 'ext' repository - support building in arbitrary places, including outside of the source tree. See comment at top of SConstruct file for more details. Regression tests are temporarily disabled; that syetem needs more extensive revisions. SConstruct: Update for new directory structure. Modify to support build trees that are not subdirectories of the source tree. See comment at top of file for more details. Regression tests are temporarily disabled. src/arch/SConscript: src/arch/isa_parser.py: src/python/SConscript: Update for new directory structure. --HG-- rename : build/SConstruct => SConstruct rename

+# M5 Python Configuration Utility
+#
+# The basic idea is to write simple Python programs that build Python
+# objects corresponding to M5 SimObjects for the desired simulation
+# configuration.  For now, the Python emits a .ini file that can be
+# parsed by M5.  In the future, some tighter integration between M5
+# and the Python interpreter may allow bypassing the .ini file.
+#
+# Each SimObject class in M5 is represented by a Python class with the
+# same name.  The Python inheritance tree mirrors the M5 C++ tree
+# (e.g., SimpleCPU derives from BaseCPU in both cases, and all
+# SimObjects inherit from a single SimObject base class).  To specify
+# an instance of an M5 SimObject in a configuration, the user simply
+# instantiates the corresponding Python object.  The parameters for
+# that SimObject are given by assigning to attributes of the Python
+# object, either using keyword assignment in the constructor or in
+# separate assignment statements.  For example:
+#
+# cache = BaseCache(size='64KB')
+# cache.hit_latency = 3
+# cache.assoc = 8
+#
+# The magic lies in the mapping of the Python attributes for SimObject
+# classes to the actual SimObject parameter specifications.  This
+# allows parameter validity checking in the Python code.  Continuing
+# the example above, the statements "cache.blurfl=3" or
+# "cache.assoc='hello'" would both result in runtime errors in Python,
+# since the BaseCache object has no 'blurfl' parameter and the 'assoc'
+# parameter requires an integer, respectively.  This magic is done
+# primarily by overriding the special __setattr__ method that controls
+# assignment to object attributes.
+#
+# Once a set of Python objects have been instantiated in a hierarchy,
+# calling 'instantiate(obj)' (where obj is the root of the hierarchy)
+# will generate a .ini file.  See simple-4cpu.py for an example
+# (corresponding to m5-test/simple-4cpu.ini).

+#
+# ConfigNode/SimObject classes
+#
+# The Python class hierarchy rooted by ConfigNode (which is the base
+# class of SimObject, which in turn is the base class of all other M5
+# SimObject classes) has special attribute behavior.  In general, an
+# object in this hierarchy has three categories of attribute-like
+# things:
+#
+# 1. Regular Python methods and variables.  These must start with an
+# underscore to be treated normally.
+#
+# 2. SimObject parameters.  These values are stored as normal Python
+# attributes, but all assignments to these attributes are checked
+# against the pre-defined set of parameters stored in the class's
+# _params dictionary.  Assignments to attributes that do not
+# correspond to predefined parameters, or that are not of the correct
+# type, incur runtime errors.
+#
+# 3. Hierarchy children.  The child nodes of a ConfigNode are stored
+# in the node's _children dictionary, but can be accessed using the
+# Python attribute dot-notation (just as they are printed out by the
+# simulator).  Children cannot be created using attribute assigment;
+# they must be added by specifying the parent node in the child's
+# constructor or using the '+=' operator.
+
+# The SimObject parameters are the most complex, for a few reasons.
+# First, both parameter descriptions and parameter values are
+# inherited.  Thus parameter description lookup must go up the
+# inheritance chain like normal attribute lookup, but this behavior
+# must be explicitly coded since the lookup occurs in each class's
+# _params attribute.  Second, because parameter values can be set
+# on SimObject classes (to implement default values), the parameter
+# checking behavior must be enforced on class attribute assignments as
+# well as instance attribute assignments.  Finally, because we allow
+# class specialization via inheritance (e.g., see the L1Cache class in
+# the simple-4cpu.py example), we must do parameter checking even on
+# class instantiation.  To provide all these features, we use a
+# metaclass to define most of the SimObject parameter behavior for
+# this class hierarchy.

+# The SmartDict class fixes a couple of issues with using the content
+# of os.environ or similar dicts of strings as Python variables:
+#
+# 1) Undefined variables should return False rather than raising KeyError.
+#
+# 2) String values of 'False', '0', etc., should evaluate to False
+#    (not just the empty string).
+#
+# #1 is solved by overriding __getitem__, and #2 is solved by using a
+# proxy class for values and overriding __nonzero__ on the proxy.
+# Everything else is just to (a) make proxies behave like normal
+# values otherwise, (b) make sure any dict operation returns a proxy
+# rather than a normal value, and (c) coerce values written to the
+# dict to be strings.
