that is not what SSA is used for. ;-)
also, well-formed SSA is dead easy to generate: just don't try to be smart,
and don't write "locals reuse logic" at all. other passes will take care of
eliminating redunant loads and locals. and then simple linear scan register
allocator will give you very surprising results. ;-)
The Great Secret of SSA is "don't be smart". each SSA pass should do only
one thing, it should do it in the easiest possible way, and only care about
repairing SSA damage it done. and then you can easily add more passes, and
choose between generated code quality and time spent on optimising.
