Once you've compiled it for one platform, you've re-bootstrapped it, at which point you can use the real compiler to cross-compile for another platform.
Ideally, you want more than one bootstrapped platform. Platforms eventually die, and you don't want to rely on an emulator for bootstrapping.
Some time from now x86_64 will fade away, and there's a large chance rust will still be around. I know that this will probably take a long time, but it's better and easier to do it now than later.
The most recent release has the ability to generate basic debugging information (see "new experimental dbgfile and dbgloc directives. " from the release notes) as Hare needed that (and IIRC a Hare contributor added it). Unfortunately, there's no documentation on it, and last I checked to see how to use it I had to go spelunking in the Hare source code.
Oh, perfect, thanks! I've been using Niri for less than a week, hadn't got to using named workspaces yet, and missed the bit in the docs where it says they can be empty.
