I agree with this. I was told this was the so called bible of compiler development and must have. I cannot recommend it.

So, I bought it (cheapest copies used were over $100), tried to read it, and got nothing out of it. I gave up about half way through. It's been a few years, but it read like no other technical CS book I can remember. If I recall, it like a theoretical explanation, a long lecture on paper.
