As has been discussed several times recently on this list,
SSA is currently not working in Jikes RVM.

As to your specific question, I think scalar SSA is essentially
a subset of Heap SSA, the latter trying to track values of and
updates to fields of objects in the heap (assuming no other
thread changes them concurrently).

I don't quite follow "dump for SSA" though; maybe that will
mean more to Dave Grove or some others more experienced with
that part of the compiler.
