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] This article provides an introduction to reading x86 assembly language, emphasizing its importance for understanding how programs operate at a fundamental level. It covers the basics of assembly syntax, common instructions, and practical tools for reading and analyzing assembly code. The author explains that while assembly is often viewed as complex, it's actually more approachable than many believe, especially for debugging and reverse engineering tasks. The article also highlights the differences between Intel and AT&T syntax, the structure of assembly instructions, and the role of registers and memory addressing in x86 architecture. |
