|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4173: Use core instead of std for builtin derive macros r=edwin0cheng a=edwin0cheng Fixed #4087. We can't use `$crate` here right now because : 1. We have to able to detect `macro` 2.0 in collecting phase for finding `rustc_builtin_macro` attrs. 2. And we have to make hygiene works for builtin derive macro. r= @flodiebold Co-authored-by: Edwin Cheng <[email protected]>

* | For associated type shorthand (T::Item), use the substs from the where clauseFlorian Diebold2020-04-264-13/+119
|/ | | | | So e.g. if we have `fn foo<T: SomeTrait<u32>>() -> T::Item`, we want to lower that to `<T as SomeTrait<u32>>::Item` and not `<T as SomeTrait<_>>::Item`.

|\ | | | | | | | | | | | | | | 4023: Fix another crash from wrong binders r=matklad a=flodiebold Basically, if we had something like `dyn Trait<T>` (where `T` is a type parameter) in an impl we lowered that to `dyn Trait<^0.0>`, when it should be `dyn Trait<^1.0>` because the `dyn` introduces a new binder. With one type parameter, that's just wrong, with two, it'll lead to crashes. Co-authored-by: Florian Diebold <[email protected]>

This is an unstable feature, but it's used in the standard library e.g. in the definition of Flatten, so we can't get away with not implementing it :) (This is cherry-picked from my recursive solver branch, where it works better, but I did manage to write a test that works with the current Chalk solver as well...) 3967: Handle `Self::Type` in trait definitions when referring to own associated type r=matklad a=flodiebold It was implemented for other generic parameters for the trait, but not for `Self`.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | 3938: fix missing match arm false positive r=flodiebold a=JoshMcguigan This fixes #3932 by skipping the missing match arm diagnostic in the case any of the match arms don't type check properly against the match expression. I think this is the appropriate behavior for this diagnostic, since `is_useful` relies on all match arms being well formed, and the case of a malformed match arm should probably be handled by a different diagnostic.
