To evolve from an advanced calculator into a programming language, we must introduce reusable, isolated blocks of code. We need Functions. Building a Register VM Interpreter - Ch. 11&#58 Variables and Scoping 2026-04-29T00:00:00+09:00 2026-04-29T00:00:00+09:00 https://the0cp.cc/posts/lang-p11/ the0cp This guide is about building a register-based VM interpreter from scratch. In this article, we are going to teach the compiler how to navigate both of these worlds. We will implement global variable routing, introduce the mechanics of Lexical Scoping to track blocks, and finally unleash the full speed of our register allocator. Building a Register VM Interpreter - Ch. 10&#58 Heap, Strings, and Hash Tables 2026-04-18T00:00:00+09:00 2026-04-18T00:00:00+09:00 https://the0cp.cc/posts/lang-p10/ the0cp This guide is about building a register-based VM interpreter from scratch. To escape this 64-bit limit, we have to look beyond the virtual stack and into the C heap. Building a Register VM Interpreter - Ch. 9&#58 The Control Flow 2026-04-16T00:00:00+09:00 2026-04-16T00:00:00+09:00 https://the0cp.cc/posts/lang-p9/ the0cp This guide is about building a register-based VM interpreter from scratch. We will upgrade the VM to understand Jump instructions, and more importantly, we will teach the single-pass compiler how to calculate exactly where those jumps should land, even when it hasn't finished compiling the code yet. Building a Register VM Interpreter - Ch. 8&#58 The VM Core 2026-04-09T00:00:00+09:00 2026-04-09T00:00:00+09:00 https://the0cp.cc/posts/lang-p8/ the0cp This guide is about building a register-based VM interpreter from scratch. We will design the memory structures required to run a program, build the dispatch loop to fetch instructions, and write the logic to finally execute the math and logic operations we worked so hard to compile.
