Eh, 64-bit desktops were becoming common a decade ago. Considering the small minority of developers using a 32-bit machine for development, I don't see that it is worthwhile to spend effort on that. Note that Rust can (and does) target various 32-bit platforms (ARM and maybe RISC-V, not sure) for cross-compile. Self-hosting on a 32-bit platform is such a minor drawback these days. 64-bit ARM processors are becoming more common these days as well.

There are still plenty of 32bit machines out there. I personally have maintained and support a Intel 4004 knockoff used for controlling a big industrial machine. And of course more modern variants of the same machine with an 8008. Some of these couldn't even run DOS but it's still supported. 32bit is not even close to be being that old and lots of machines, applications or platforms require it and they need maintenance. Especially OpenBSD is a system that I as a Linux-fan recognize for supporting old hardware much better than Linux. And it's not only 32bit x86, there is plenty of other architectures limited to 32bit, mostly from the ARM sector but I believe some older MIPS and other even more exotic arch's are supported. If rust can't selfhost on x86 how can we expect it to selfhost on more exotic 32bit hardware that BSD supports?

  Oh, I wasn't implying that OBSD or NBSD should adopt Rust as a development language. Not at all. My point is more that I wouldn't want the Rust developers to spend time on making it able to self-host on 32-bit platforms. I'd prefer they spend their time elsewhere, that's all.

    > I'd prefer they spend their time elsewhere, that's all. And I'm sure the OpenBSD developers would prefer to spend their time on OpenBSD instead of working around Rust's lack of support for a platform that OpenBSD supports. I'm still kind of surprised that when the question of "why doesn't OpenBSD switch to Rust?" and the answer was "because Rust doesn't self host on a platform we support" that the response has been "well drop that platform." How about: no. How about: if someone wants Rust to be a viable option, then they have to adjust Rust to be a viable option, not ask other projects to massively constrain their currently working support of a platform. I hate to sound like the old geezer, but I get the impression that many people here have no clue about software beyond desktop and mobile. It's like they don't even realize that firmware and operating systems have to be written and maintained on older hardware. There is a lot of software out there running on legacy hardware that the world depends upon which you never see.
