> m68k might be a bad example to pick. I was using gcc to target m68k on netbsd in the mid 1990s. It's very battle tested.
That was 30 years ago! Having worked on LLVM: it's very easy for optimizing compilers to regress on smaller targets. I imagine the situation is similar in GCC.
(The underlying point is simpler: explicit is better than implicit, and all Rust is doing is front-loading the frustration from "this project was never tested on this platform but we pretend like it was" to "this platform is not well tested." That's a good thing.)
