| | | | | Creating an implementation for a dynamic language using just in time compilation (JIT)techniques involves a lot of compromisesmainly between complexity of the implementation, speed, warm-up time and memory usage. Especially speed is a difficult trade-off because it's very easy to end-up spending more time optimizing a piece of code and emitting the assembly than we... | |

| | | 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... | ||
