| | | | | In this post, we are going to take a deep dive into pointer tagging, where metadata is encoded into a word-sized pointer. Doing so allows us to keep a compact representation that can be passed around in machine registers. This is very common in implementing dynamic programming languages, but can really be used anywhere that additional runtime information is needed about a pointer. We will look at a handful of different ways these pointers can be encoded and see how the compiler can optimize them for diff... | |

| | | [AI summary] The blog post discusses the evolution of programming languages, focusing on Rust and Zig's approaches to handling formatted output. It highlights the challenges in C's format string system, the use of macros in Rust, and Zig's ability to handle formatted output without special compiler cases, relying on userland code. The post also touches on the trade-offs of macros and the design goals of Zig to provide power without the drawbacks of macro-based systems. | ||
