As xtracto mentioned, parsing and enough automata theory to understand what context free grammars are and where they fall should be part of your basic toolkit, but how they generate code is even more useful to C programmers. (One study done decades ago found that the average C statement resulted in 2.7 CICS assembly language commands.)
The Dragon Book is not the best teaching tool out there. Maybe try The Elements of Computing Systems Chapters 10 & 11? You might need to peek at the earlier chapters to get a grounding in the particular assembly language they use.
