Add tests for nested macro_rules edition behavior by ehuss · Pull Request #136509 · rust-lang/rust (original) (raw)

Though I can't think of a way to extend that to the aux-crate, which is only differs in the edition.

In theory they might be able to include! some common file and just differ in the compile-flags, but I don't foresee us changing these two aux files often anyways, so seems overkill and another layer of indirection. The current duplication seems completely fine.
