@aramh So how do I compile Go code in freestanding mode, in a way that will work on an OS-less system? Rust can do that.

@marcan42 you have to revive the bare-metal target. it's not there yet, but it's relatively trivial to resurrect, one or two days of work.

@aramh How does it deal with lack of GC? Last I checked Go pretty heavily depended on that.

@marcan42 But you do have a GC, unless I misunderstand what you mean.

@aramh Let me put it this way: can I compile Go code for a microcontroller with 32KiB of RAM and no MMU?

@marcan42 No, not with current runtime, too little RAM. But the lack of MMU is no problem. You can probably get away with 256-512kB of RAM.

@marcan42 If you're willing to do the work, you can implement a custom small runtime.

@marcan42 You can compile Go code with a custom runtime like this: https://github.com/4ad/go/blob/90da06ad5e53229d3148bced2a95a9a6b135ca5e/alt/mkfile …
