Take if from a long time compiler write who has nearly 30 years experience
working with SSA: SSA is no panacea. It is a representation that makes
some optimizations easier to express and sometimes more effective. Many of
the optimizations that SSA facilitates tend to raise register pressure. I
can be a very delicate balancing act.
Optimizing for size is a dark art. Most compiler projects invest
relatively little effort in that direction.
