Having implemented a few `state of the art' compiler algorithms (and a few
beyond the state of the art), I can say that most competent graduate
students could code them, but most companies wouldn't implement them. The
key problem is that most papers present enough details, but don't present
enough evidence that a technique is effective. A rational project manager
would not commit the resources to try out these algorithms. There are
exceptions, of course, but compiler papers frequently use towers of hanoi
or puzzle-sized benchmarks.
