| 在这里详述 compiler/Let's build a compiler/ch1。 | 申明不会采用典型教科书上关于编译器的教学顺序，比如： o An introductory chapter describing what a compiler is. o A chapter or two on syntax equations, using Backus-Naur Form (BNF). o A chapter or two on lexical scanning, with emphasis on deterministic and non-deterministic finite automata. o Several chapters on parsing theory, beginning with top-down recursive descent, and ending with LALR parsers. o A chapter on intermediate languages, with emphasis on P-code and similar reverse polish representations. o Many chapters on alternative ways to handle subroutines and parameter passing, type declarations, and such. o A chapter toward the end on code generation, usually for some imaginary CPU with a simple instruction set. Most readers (and in fact, most college classes) never make it this far. o A final chapter or two on optimization. This chapter often goes unread, too. |
