Explore effective strategies for debugging WebAssembly (WASM) applications in this informative conference talk. Delve into the current state of WASM debugging, drawing parallels with technologies like LLVM, and learn about open-source tools such as Modsurfer. Discover a proposed compile-time debugging approach and understand the crucial role of LLVM Intermediate Representation (IR) in the debugging process. Gain valuable insights into the conversion of source code into LLVM IR and its subsequent stages, equipping yourself with the knowledge and techniques necessary to effectively debug WASM applications and navigate the complex challenges posed by this technology.
