> Even once Rust has first-class support for GCC as a backend, I suspect that supporting the long tail of more obscure platforms will be an ongoing process. Linux's own support for the long tail of more obscure platforms is also an ongoing process. People aren't asking for Rust to do better than the Linux kernel in that regard, they're just asking for it to not immediately disqualify a range of platforms. One could reasonably argue about the value of supporting those platforms, but the Linux kernel, reasonably, doesn't want to make that decision on the sole basis of the availability of Rust support. > And for exceptionally weird platforms (e.g. where a byte isn't 8 bits) Rust may never bother to contort itself enough to support those, although perhaps Linux also doesn't support such platforms? Linux doesn't support such platforms, and I don't think Rust ever will either.
