2019-02-13Rollup merge of #58273 - taiki-e:rename-dependency, r=matthewjasperMazdak Farrokhzad-1/+1
Rename rustc_errors dependency in rust 2018 crates I think this is a better solution than `use rustc_errors as errors` in `lib.rs` and `use crate::errors` in modules. Related: rust-lang/cargo#5653 cc #58099 r? @Centril
2019-02-13Rollup merge of #58166 - euclio:deprecation-shorthand, r=petrochenkovMazdak Farrokhzad-3/+9

2019-02-12Auto merge of #58341 - alexreg:cosmetic-2-doc-comments, r=steveklabnikbors-4/+3
Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

feature list while we could make this change (it's all unstable after all), there are crates.io crates that use the feature and that the compiler depends upon. We can instead roll out this feature while still supporting the old way.

2019-02-07Auto merge of #57998 - niklasf:align-enum, r=nagisabors-0/+14
Allow #[repr(align(x))] on enums (#57996) Tracking issue: #57996 Implements an extension of [RFC 1358](https://github.com/rust-lang/rfcs/blob/master/text/1358-repr-align.md) behind a feature flag (`repr_align_enum`). Originally introduced here for structs: #39999. It seems like only HIR-level changes are required, since enums are already aware of their alignment (due to alignment of their limbs). cc @bitshifter

2019-01-26Auto merge of #55641 - nagisa:optimize-attr, r=pnkfelixbors-0/+9
Implement optimize(size) and optimize(speed) attributes This PR implements both `optimize(size)` and `optimize(speed)` attributes. While the functionality itself works fine now, this PR is not yet complete: the code might be messy in places and, most importantly, the compiletest must be improved with functionality to run tests with custom optimization levels. Otherwise the new attribute cannot be tested properly. Oh, and not all of the RFC is implemented – attribute propagation is not implemented for example. # TODO * [x] Improve compiletest so that tests can be written; * [x] Assign a proper error number (E9999 currently, no idea how to allocate a number properly); * [ ] Perhaps reduce the duplication in LLVM attribute assignment code…

2019-01-16Auto merge of #57321 - petrochenkov:atokens, r=nikomatsakisbors-143/+242
Implement basic input validation for built-in attributes Correct top-level shape (`#[attr]` vs `#[attr(...)]` vs `#[attr = ...]`) is enforced for built-in attributes, built-in attributes must also fit into the "meta-item" syntax (aka the "classic attribute syntax"). For some subset of attributes (found by crater run), errors are lowered to deprecation warnings. NOTE: This PR previously included https://github.com/rust-lang/rust/pull/57367 as well.

2019-01-14Rollup merge of #57572 - Centril:unaccept-extern-in-path, r=petrochenkovMazdak Farrokhzad-24/+5
Unaccept `extern_in_paths` Based on completed fcp-close in https://github.com/rust-lang/rust/issues/55600, this removes `extern_in_path` (e.g. `extern::foo::bar`) from the language. The changes are primarily reversing https://github.com/rust-lang/rust/commit/32db83b16e06cb5cca72d0e6a648a8008eda0fac. Closes https://github.com/rust-lang/rust/issues/55600 r? @petrochenkov

Stabilize `uniform_paths` Address all the things described in https://github.com/rust-lang/rust/issues/56417. Assign visibilities to `macro_rules` items - `pub` to `macro_export`-ed macros and `pub(crate)` to non-exported macros, these visibilities determine how far these macros can be reexported with `use`. Prohibit use of reexported inert attributes and "tool modules", after renaming (e.g. `use inline as imported_inline`) their respective tools and even compiler passes won't be able to recognize and properly check them. Also turn use of uniform paths in 2015 macros into an error, I'd prefer to neither remove nor stabilize them right away because I still want to make some experiments in this area (uniform path fallback was added to 2015 macros used on 2018 edition in https://github.com/rust-lang/rust/pull/56053#issuecomment-441405140). UPDATE: The last commit also stabilizes the feature `uniform_paths`.

2018-12-29Auto merge of #56225 - alexreg:type_alias_enum_variants, r=petrochenkovbors-1/+4
Implement RFC 2338, "Type alias enum variants" This PR implements [RFC 2338](https://github.com/rust-lang/rfcs/pull/2338), allowing one to write code like the following. ```rust #![feature(type_alias_enum_variants)] enum Foo { Bar(i32), Baz { i: i32 }, } type Alias = Foo; fn main() { let t = Alias::Bar(0); let t = Alias::Baz { i: 0 }; match t { Alias::Bar(_i) => {} Alias::Baz { i: _i } => {} } } ``` Since `Self` can be considered a type alias in this context, it also enables using `Self::Variant` as both a constructor and pattern. Fixes issues #56199 and #56611. N.B., after discussing the syntax for type arguments on enum variants with @petrochenkov and @eddyb (there are also a few comments on the [tracking issue](https://github.com/rust-lang/rust/issues/49683)), the consensus seems to be treat the syntax as follows, which ought to be backwards-compatible. ```rust Option::<u8>::None; // OK Option::None::<u8>; // OK, but lint in near future (hard error next edition?) Alias::<u8>::None; // OK Alias::None::<u8>; // Error ``` I do not know if this will need an FCP, but let's start one if so.
