2019-08-04Auto merge of #62816 - estebank:type-ascription-macros, r=petrochenkovbors-6/+36

2019-08-03Auto merge of #63180 - varkor:trait-alias-impl-trait, r=Centrilbors-30/+13
Change opaque type syntax from `existential type` to type alias `impl Trait` This implements a new feature gate `type_alias_impl_trait` (this is slightly different from the originally proposed feature name, but matches what has been used in discussion since), deprecating the old `existential_types` feature. The syntax for opaque types has been changed. In addition, the "existential" terminology has been replaced with "opaque", as per previous discussion and the RFC. This makes partial progress towards implementing https://github.com/rust-lang/rust/issues/63063. r? @Centril

Unconfigure compiler unit test files during normal build I haven't touched libstd though, it had a lot of tests and I'm not sure the people maintaining it want this. Closes https://github.com/rust-lang/rust/issues/61097 r? @Mark-Simulacrum

2019-07-28Rollup merge of #62550 - Centril:rest-patterns, r=petrochenkovMazdak Farrokhzad-290/+235
Implement RFC 2707 + Parser recovery for range patterns Implement https://github.com/rust-lang/rfcs/pull/2707. - Add a new basic syntactic pattern form `ast::PatKind::Rest` (parsed as `..` or `DOTDOT`) and simplify `ast::PatKind::{Slice, Tuple, TupleStruct}` as a result. - Lower `ast::PatKind::Rest` in combination with the aforementioned `PatKind` variants as well as `PatKind::Ident`. The HIR remains unchanged for now (may be advisable to make slight adjustments later). - Refactor `parser.rs` wrt. parsing sequences and lists of things in the process. - Add parser recovery for range patterns of form `X..`, `X..=`, `X...`, `..Y`, `..=Y`, and `...Y`. This should make it easy to actually support these patterns semantically later if we so desire. cc https://github.com/rust-lang/rust/issues/62254 r? @petrochenkov
