I suppose it's not strange to see WASM come up -- last weekend I was considering doing something even weirder: writing a WASM to Thumb2 AoT compiler so I could leverage Go's built-in WASM support.

This project seems more immediately useful :)

That's pretty cool!

If you want something now, I've also written and abandoned this: https://github.com/aykevl/tinygo-gccgo

It actually worked fairly well, but the code was way too bloated to be useful.

Honestly for what I'm doing what you have here is a pretty reasonable start. I'm comfortable writing (and calling into) C where the Go bits aren't in place yet, and I'm a lot more familiar with LLVM's internals than with GCC's if I need to debug something. We'll see what I get up to after brunch.

One request: if you're open to PRs (I can't promise I'll send any, but I'm trying to get into a habit of contributing to OSS with my hobby hackery), can you add a LICENSE file (context: the OSS patching policy I'm bound by is very friendly for projects on Github under most licenses -- https://opensource.google.com/docs/patching/ -- it's more problematic when the license for the code is undefined)?

I'm certainly open to PRs :)

Good catch on the LICENSE file, I totally forgot about it. I've added it now.

Yeah, just wait until you see multiple megabytes of WASM instructions for tiny progs or the realize the team does not care about non-web targets. You're much better off leveraging Rust's WASM support for resource limited, non-web WASM targets.

In my case I was less interested in the WASM part of it than I was in something targeting a "no OS" environment. That said, for my target (those little Pine64 RTL8710 Cortex M3 MCU) you're almost certainly right. On the other hand it's a hobby project, and I like writing Go while I find writing Rust to be a bit of a chore. Also, it's a hobby project, so distractions like re-targeting WASM to the ARMv7-M are half of the fun :)
