2019-07-18Don't drop DiagnosticBuilder if parsing failsJonathan Goodman-1/+1
Beta backport of #62668. If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.

2019-07-01Auto merge of #61682 - Centril:stabilize-type_alias_enum_variants, ↵bors-3/+2
r=petrochenkov Stabilize `type_alias_enum_variants` in Rust 1.37.0 Stabilize `#![feature(type_alias_enum_variants)]` which allows type-relative resolution with highest priority to `enum` variants in both expression and pattern contexts. For example, you may now write: ```rust enum Option<T> { None, Some(T), } type OptAlias<T> = Option<T>; fn work_on_alias(x: Option<u8>) -> u8 { match x { OptAlias::Some(y) => y + 1, OptAlias::None => 0, } } ``` Closes https://github.com/rust-lang/rfcs/issues/2218 Closes https://github.com/rust-lang/rust/issues/52118 r? @petrochenkov

libsyntax: Fix some Clippy warnings When I was working on it before a lot of these popped up in the RLS so I figured I'll send a small patch fixing only the (hopefully) uncontroversial ones. Others that could be also fixed included also [`clippy::print_with_newline`](https://rust-lang.github.io/rust-clippy/master/index.html#print_with_newline) and [`clippy::cast_lossless`](https://rust-lang.github.io/rust-clippy/master/index.html#cast_lossless). Should I add them as well? since most of it touches libsyntax... r? @petrochenkov

2019-06-25cleanup: rename name_from to symbol_fromAleksey Kladov-20/+19
Lexer uses Symbols for a lot of stuff, not only for identifiers, so the "name" terminology is just confusing.

2019-06-24Auto merge of #62075 - Centril:guardless-match-arms, r=petrochenkovbors-31/+10
Remove `ast::Guard` With the introduction of `ast::ExprKind::Let` in https://github.com/rust-lang/rust/pull/60861, the `ast::Guard` structure is now redundant in terms of representing [`if let` guards](https://github.com/rust-lang/rust/issues/51114) in AST since it can be represented by `ExprKind::Let` syntactically. Therefore, we remove `ast::Guard` here. However, we keep `hir::Guard` because the semantic representation is a different matter and this story is more unclear right now (might involve `goto 'arm` in HIR or something...). r? @petrochenkov
2019-06-23Auto merge of #62070 - ia0:rustfmt, r=petrochenkovbors-235/+273
Run rustfmt on some libsyntax files As part of #62008, run rustfmt on: - src/libsyntax/ext/tt/macro_rules.rs - src/libsyntax/ext/tt/quoted.rs There is no semantic change. To fix potential merge conflicts, simply choose the other side then run rustfmt and fix any tidy check (like line length).
2019-06-23Auto merge of #60861 - Centril:let-chains-ast-intro, r=petrochenkovbors-153/+138
[let_chains, 2/6] Introduce `Let(..)` in AST, remove IfLet + WhileLet and parse let chains Here we remove `ast::ExprKind::{IfLet, WhileLet}` and introduce `ast::ExprKind::Let`. Moreover, we also: + connect the parsing logic for let chains + introduce the feature gate + rewire HIR lowering a bit. However, this does not connect the new syntax to semantics in HIR. That will be the subject of a subsequent PR. Per https://github.com/rust-lang/rust/issues/53667#issuecomment-471583239. Next step after https://github.com/rust-lang/rust/pull/59288. cc @Manishearth re. Clippy. r? @oli-obk

2019-06-23Rollup merge of #62068 - ia0:fix_meta_var, r=petrochenkovMazdak Farrokhzad-6/+6
Fix meta-variable binding errors in macros The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact. Found by https://github.com/rust-lang/rust/pull/62008
