This broke doing a check build of cg_clif on x86, which rust's CI does. I use cranelift-native for implementing -Ctarget-cpu=native in cg_clif. For this purpose just returning no features on unsupported platforms is fine.

@bjorn3 IMHO it's reasonable for cranelift-native to refuse to compile on a platform (i686) that Cranelift doesn't support, since its purpose is to query what the native platform is from Cranelift's point of view. Is there a way to exclude the cg_clif check build from running there?

Probably, but it would also break cross-compiling scenarios where cranelift-native would never be called at runtime.

Hmm, yeah, actually it seems that any other non-supported platform will compile here (returning an Err at runtime); that's probably the more reasonable option. Happy to review a PR to remove the block with the compile-error. The original issue we were trying to solve was that folks were trying to build Cranelift embedders (like Wasmtime or Viceroy wrapping it) for i686 and were misled by a successful compile; but I suppose a runtime error is still good enough for that purpose since it's clear enough ("unsupported architecture").
