I am looking for a simple compiler that compiles a simple language, I need it to write a paper about it and to learn how compilers work, I am not looking for a sophisticated thing just a simple language (by simple I mean a small code because for example gcc is toooooo big). any help is appreciated.
If you want to look at code, I'm very impressed with Eijiro Sumii's MinCaml compiler.
It's only 2000 lines long.
It compiles a pretty interesting source language.
It generates real machine code, none of this namby-pamby C or LLVM stuff :-)
Speed of compiled code is competetive with gcc and the native OCaml compilers.
The compiler is designed for teaching.
Did I mention I've been very impressed?
