Static single assignment is very nice.  We have been using it in our
Smalltalk compiler and it has worked out well.  It might store the
same information as use-def chains, but it stores it in a form that
is much easier to access and maintain.  I don't worry about space,
because our routines are small, so I can't comment on that, but the
speed claims seem to be accurate.
