| // Functions can have target-cpu applied. On apple-darwin this is super important, |
| // since you can have binaries which mix x86 and aarch64 code that are compatible |
| // with both architectures. So we can't just reject target_cpu on EIIs since apple |
| // puts them on by default. The problem: we generate aliases. And aliases cannot |
| // get target_cpu applied to them. So, instead we should, in the case of functions, |
| // generate a shim function. For statics aliases should keep working in theory. |
| // In fact, aliases are only necessary for statics. For functions we could just |
| // always generate a shim and a previous version of EII did so but I was sad |
| // that that'd never support statics. |
| //@ ignore-macos |
| // Tests EIIs with default implementations. |
| // When there's no explicit declaration, the default should be called from the declaring crate. |
