Change subject: Make sub/superclass queries in JTypeOracle more efficient.
......................................................................
Make sub/superclass queries in JTypeOracle more efficient.
Assign a unique id to each class during for global optimization, such
that the following invariant holds:
a.id < b.id for b != a and b subclass of a.
forall c.id > a.id, c.id <= max_{b subclass of a}(b.id) . c subclass of a
The aforementioned invariant allows to respond to the query subclass(a,b)
very
cheaply with just two integer comparisons (plus pointer dereferences).
