The book doesn't have 2024 in the title. I suspect they put it there because last time a post about this book was made, I noted that it was from 2022, not realizing that the book has now been released in 2024. https://news.ycombinator.com/item?id=40940799 > So what's different about writing a compiler in 2024 than say 10, 20, or 30 years ago? As far as I can tell, the main difference is that static single assignment (SSA) as an intermediate form was not the norm 30 years ago, but it is nowadays. Also, in newer books, it's more common to go over global register allocation now, whether that's graph coloring or linear scan register allocation. If you read old compiler books, the main optimizations they talk about are use-def chains, moving computations out of loops, and using the local and tree-based Sethi-Ullman register allocation algorithm. |
