Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
