don't ICE when normalizing closure input tys `normalize_and_add_constraints` doesn't add entries in `universe_causes` when creating new universes, causing an ICE. Remove it! Add spans to track normalization constraints. Fix couple places where `universe_causes` is not updated correctly to track newly added universes. 2022-07-27 17:54:59 +00:00			error: implementation of `Trait` is not general enough

don't normalize in astconv We delay projection normalization to further stages in order to register user type annotations before normalization in HIR typeck. There are two consumers of astconv: ItemCtxt and FnCtxt. The former already expects unnormalized types from astconv, see its AstConv trait impl. The latter needs `RawTy` for a cleaner interface. Unfortunately astconv still needs the normalization machinery in order to resolve enum variants that have projections in the self type, e.g. `<<T as Trait>::Assoc>::StructVariant {}`. This is why `AstConv::normalize_ty_2` is necessary. 2022-09-17 18:35:47 +00:00			`error: aborting due to 2 previous errors`
