The article challenges the common classification of WebAssembly (Wasm) as a pure stack machine, revealing that its design includes register-like behavior for temporary values. This distinction affects how instructions are optimized and executed, offering deeper insight into Wasm's internal mechanics. The analysis is based on hands-on experience writing Wasm instructions manually, highlighting a nuanced but important technical detail.
Background
WebAssembly (Wasm) is a low-level binary instruction format designed for high-performance execution in web browsers and other environments, often described as a stack-based virtual machine. It enables languages like C++ and Rust to run efficiently on the web.
