IMO, there haven't really been any major/drastic developments, rather lots
of micro-level tweaking and optimizations.


granted, SSA does add some, but the effect is by no means drastic (and IMO
more in terms of allowing more flexibility in terms of low-level code
generation rather than in terms of performance).


many other changes are more in terms of the underlying architectures than
the compiler structure.




now, some people may disagree, but this is how it looks to me...
