[llvm-dev] How about add webassembly/wasi support in llvm-libc.
Cause llvm-libc are in early stage, and we can easily catch up the support
with linux.
After we add wasi support in llvm-lic, we can easily get a usable llvm-libc
across different platform such as linux/windows/macos/android. don't know
if iOS is a target, but these target are very much enough

+Dan Gohman My guess is that WASI is not stable enough for this to make sense, but it would be good to hear Dan's take on this.

[llvm-dev] [libc-dev] How about add webassembly/wasi support in llvm-libc.
Somehow I wish not all parts of a libc but parts that can be provided without a JavaScript wrapper for .wasm can be provided from llvm's libc (leaving a stab implementation for the rest like file system). I've put together a minimal libc on [1] so using a 26kb .wasm binary file one can decode both PNG and JPG using this [2] simple to integrate JavaScript code, can be easily ported in other contexts .wasm can be interpreted without worrying about a helper. I had to use -nostdlib and -nostdinc in my build script but I wished the llvm-libc initiative can make it simpler so I don't have to put together a minimal libc for my need. Something similar can be achieved in Rust world using --target wasm32-unknown-unknown e.g. [3] which I guess can be best lead here also in terms what can be in scope of this work.
