Initial commit of OpenSPARC T2 architecture model.

[OpenSPARC-T2-SAM] / sam-t2 / devtools / v8plus / lib / python2.4 / lib-old / dump.py

# Module 'dump'
#
# Print python code that reconstructs a variable.
# This only works in certain cases.
#
# It works fine for:
# - ints and floats (except NaNs and other weird things)
# - strings
# - compounds and lists, provided it works for all their elements
# - imported modules, provided their name is the module name
#
# It works for top-level dictionaries but not for dictionaries
# contained in other objects (could be made to work with some hassle
# though).
#
# It does not work for functions (all sorts), classes, class objects,
# windows, files etc.
#
# Finally, objects referenced by more than one name or contained in more
# than one other object lose their sharing property (this is bad for
# strings used as exception identifiers, for instance).

# Dump a whole symbol table
#

    for key in dict.keys():
        dumpvar(key, dict[key])

# Dump a single variable

    import sys
    t = type(x)
    if t == type({}):
        print name, '= {}'
