Same here, at FU Berlin. We spent several weeks on LR and LALR parsers and such and, IIRC, even more than a week on regular expressions. Somehow we talked about two-address and three-address instructions, but never seemed to do any code generation, and certainly no optimization. It was very disappointing.

I agree

At the moment, some of us in the PGH FP group are working through https://www.cs.cmu.edu/~rwh/pfpl/, and so far I vastly prefer it. It is math heavy, which I like for various personal reasons which are irrelevant here, but it also skips parsing!
