Writing a C compiler in 500 lines of Python
A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Lessons from Writing a Compiler
The prototypical compilers textbook is: 600 pages on parsing theory. Three pages of type-checking a first-order type system like C. Zero pages on storing and checking the correctness of declarations (the “symbol tableâ€). Zero pages on the compilation model, and efficiently implementing separate compilation. 450 pages on optimization and code generation. The standard academic literature is most use

(To follow my compiler related posts, either subscribe to my main RSS feed, or the compiler specific one ) Back in March 2008 I started publishing a series on how to write a compiler in Ruby, bottom up, that is, starting with the code generator and working my way up instead of the more traditional approach of writing the parser first. Here are the parts I've published on my blog so far. (The bits
