Exploring Missed Optimizations in WebAssembly Optimizers

The prosperous trend of deploying complex applications to web browsers has boosted the development of WebAssembly (wasm) compilation toolchains. Software written in different high-level programming languages are compiled into wasm executables, which can be executed fast and safely in a virtual machine. The performance of wasm executables depends highly on compiler optimizations. Despite the prosperous use of wasm executables, recent research has indicated that real-world wasm applications are slower than anticipated, suggesting deficiencies in wasm optimizations.
