As bjorn3 pointed out, you might need something like #[cfg_attr(feature = "x86", ignore)] here and below instead.

Thank you! However, x86 is a feature of cranelift-codegen, not cranelift-frontend. Is there a way to check from the _frontend_ crate if the x86 backend is available?
(sorry if it's a newbie question!)

Ah, it's a very good question. This particular crate shouldn't have tests taht depend on specific features of other crates, otherwise they wouldn't be run by our automation.

The behavior of cranelift-codegen, in the absence of specifying a target architecture for which one would like to compile, is to target the host architecture (this happens in cranelift-codegen's build.rs script). But that doesn't _enable_ the Cargo feature either, so we couldn't even guard against the cranelift-codegen's x86 feature here.

So I think that checking against the target_arch is actually the right way to go: on a x86_64 host, the x86_64 target will be enabled by default. Sorry for the back and forth here, you were probably right in the first place :)
Would still be nice to use the cfg_attr directive instead.
