Hacker News with Generative AI: Compiler Optimization

Flattening ASTs and other compiler data structures (2023) (cs.cornell.edu)
Arenas, a.k.a. regions, are everywhere in modern language implementations. One form of arenas is both super simple and surprisingly effective for compilers and compiler-like things. Maybe because of its simplicity, I haven’t seen the basic technique in many compiler courses—or anywhere else in a CS curriculum for that matter. This post is an introduction to the idea and its many virtues.

Scalable self-improvement for compiler optimization (research.google)
We introduce Iterative BC-Max, a novel technique that aims to reduce the size of the compiled binary files by improving inlining decisions. We describe several benefits to using this approach compared to using off-the-shelf RL algorithms.
