Writing a Fast Compiler
A deep dive into techniques for building fast programming language compilers, targeting 500,000+ lines per second on a single core. Covers language design choices favoring easy parsing, memory region allocation instead of malloc/free, representing identifiers as integers instead of strings, optimizing the common (error-free) path, lazy compilation of unused code, and building a custom x64 code generator that is 30x faster than LLVM. Includes concrete data structure and algorithm choices like linear scan register allocation and two-pass assembly.
