Stabilize impl_header_lifetime_elision in 2015 ~~This is currently blocked on https://github.com/rust-lang/rust/issues/54902; it should be good after that~~ It's already stable in 2018; this finishes the stabilization. FCP completed (https://github.com/rust-lang/rust/issues/15872#issuecomment-417953153), proposal (https://github.com/rust-lang/rust/issues/15872#issuecomment-412759783).

2018-10-05Auto merge of #54336 - petrochenkov:preuni, r=alexcrichtonbors-4/+0
resolve: Some refactorings in preparation for uniform paths 2.0 The main result is that in-scope resolution performed during macro expansion / import resolution is now consolidated in a single function (`fn early_resolve_ident_in_lexical_scope`), which can now be used for resolving first import segments as well when uniform paths are enabled. r? @ghost

Stabilize pattern_parentheses feature Addresses #51087 . Stabilizes the previously unstable feature `pattern_parentheses` which enables the use of `()` in match patterns.
2018-09-25Auto merge of #53542 - alexreg:impl-trait-in-bindings, r=cramertjbors-2/+5
`impl trait` in bindings (feature: impl-trait-existential-types) This PR enables `impl Trait` syntax (opaque types) to be used in bindings, e.g. * `let foo: impl Clone = 1;` * `static foo: impl Clone = 2;` * `const foo: impl Clone = 3;` This is part of [RFC 2071](https://github.com/rust-lang/rfcs/blob/master/text/2071-impl-trait-existential-types.md) ([tracking issue](https://github.com/rust-lang/rust/issues/34511)), but exists behind the separate feature gate `impl_trait_in_bindings`.

2018-09-25Auto merge of #53693 - scottmcm:marker-trait-attribute, r=nikomatsakisbors-0/+9
Support an explicit annotation for marker traits From the tracking issue for rust-lang/rfcs#1268: > It seems obvious that we should make a `#[marker]` annotation. ~ https://github.com/rust-lang/rust/issues/29864#issuecomment-368959441 This PR allows you to put `#[marker]` on a trait, at which point: - [x] The trait must not have any items ~~All of the trait's items must have defaults~~ - [x] Any impl of the trait must be empty (not override any items) - [x] But impls of the trait are allowed to overlap r? @nikomatsakis

2018-09-23Auto merge of #54325 - michaelwoerister:incr-thinlto-tests, r=alexcrichtonbors-0/+6
incr.comp.: Allow for more fine-grained testing of CGU reuse and use it to test incremental ThinLTO. This adds some tests specifically targeted at incremental ThinLTO, plus the infrastructure for tracking the kind of cache hit/miss we had for a given CGU. @alexcrichton, let me know if you can think of any more tests to add. ThinLTO works rather reliably for small functions, so we should be able to test it in a robust way. I think after this lands it might time for a "Help us test incremental ThinLTO" post on irlo. r? @alexcrichton

2018-09-18Rollup merge of #54299 - snaedis:issue-54246, r=varkorGuillaume Gomez-7/+10
Issue 54246 I added the option of providing a help message for deprecated features, that takes precedence over the default `help: remove this attribute` message, along with messages for the features that mention replacements in the reason for deprecation. Fixes #54246.

resolve: Relax shadowing restrictions on macro-expanded macros Previously any macro-expanded macros weren't allowed to shadow macros from outer scopes. Now only "more macro-expanded" macros cannot shadow "less macro-expanded" macros. See comments to `fn may_appear_after` and added tests for more details and examples. The functional changes are a21f6f588fc28c97533130ae44a6957b579ab58c and 46dd365ce9ca0a6b8653849b80267763c542842a, other commits are refactorings.
