In Standardizing WASI: A system interface to run WebAssembly outside the web

kodablah·Mar 27, 2019

Been hoping a stdlib for WASM would spring up. So if I wanted to implement a WASI backend (e.g. on the JVM), are the function definitions I should implement here: [0]? I assume string, array, struct, etc layout in WASM mem is as C expects? Also, is it a goal to provide a test suite to test conforming backend implementations (may already be there, didn't look)? Finally, pardon my lack of research before asking, does this mean that an LLVM-based WASM compilation can target this instead of emscripten/libc and the final WASM could reference all of these API pieces as a imports? Is there an expected posix/libc-to-wasi lib? 0 - https://github.com/CraneStation/wasmtime-wasi/blob/wasi/docs...
