New Revision: 25680
Modified:
pypy/dist/pypy/translator/simplify.py
Log:
allow removal of unused imports.
Reason: constant imports detected during flowing.
XXX maybe it is better to not do this statically, but carry a list of things
to be cleaned up which became useless after flowing? Maybe in the space instance or graph?
