A really interesting discussion of array-oriented compilation architectures. Tries to answer the same sorts of questions I’ve been asking myself about making compilers faster – although I think I come to different conclusions right now.

Amazing dissertation by Aaron Wen-yao Hsu, demonstrating a novel memory layout for ASTs and advocating for bottom-up traversal patterns. The fact that the compiler is just 17 lines of APL (which I can’t read in the slightest) is even cooler.
