Looking at https://github.com/fishinabarrel/linux-kernel-module-rust... it seems that a lot of architectures not currently supported have in fact been removed from LLVM at one point or another. Perhaps as old architectures are dropped from linux the gap will close.

Compiling Rust with GCC: an update

That's what I think too. Of these ARC (maybe Xtensa) seem like the only one that is likely to be still considered for current designs. This will only accelerate as ARM and RISC-V continue to displace custom cores.

Assuming a very optimistic timeline of two years until widespread Rust adoption in the Kernel and another two years until the stale distros actually pick up those kernels, I think most of these will be long gone from the Linux tree by the time this is relevant. Or have LLVM backends. Cadence and Synopsys certainly don't lack the resources to make that happen if they want to.
