Also note that store motion was initially implemented to deal with a
specific class of store motions -- if you did anything outside the
very limited set of things it knew about no motions would be performed.

The idea (of course) was to get the base algorithms working correctly,
then tie in the aliasing code to make them more effective.

For various reasons I think it's highly unlikely Daniel had the
original store motion code as it was originally done on a customer
specific branch inside Cygnus's repository.  ANd yes, the various
merges, including the merge into the head of Cygnus's repository
were rather brutal.
