2019-06-16Auto merge of #61347 - Centril:stabilize-underscore_const_names, r=petrochenkovbors-6/+35
Stabilize underscore_const_names in 1.37.0 You are now permitted to write: ```rust const _: $type_expression = $term_expression; ``` That is, we change the [grammar of items](https://github.com/rust-lang-nursery/wg-grammar/blob/9d1984d7ae8d6576f943566539a31a5800644c57/grammar/item.lyg#L3-L42), as written in [the *`.lyg`* notation](https://github.com/rust-lang/gll/tree/263bf161dad903e67aa65fc591ced3cab18afa2a#grammar), from: ```java Item = attrs:OuterAttr* vis:Vis? kind:ItemKind; ItemKind = | ... | Const:{ "const" name:IDENT ":" ty:Type "=" value:Expr ";" } | ... ; ``` into: ```java Item = attrs:OuterAttr* vis:Vis? kind:ItemKind; ItemKind = | ... | Const:{ "const" name:IdentOrUnderscore ":" ty:Type "=" value:Expr ";" } | ... ; IdentOrUnderscore = | Named:IDENT | NoName:"_" ; ``` r? @petrochenkov

2019-05-19Rollup merge of #60370 - Richard-W:const-layout-construction, r=sfacklerMazdak Farrokhzad-0/+21
Mark core::alloc::Layout::from_size_align_unchecked const Makes it possible (pending stabilization of #57563 (`const_fn`)) to rewrite code like ```rust const BUFFER_SIZE: usize = 0x2000; const BUFFER_ALIGN: usize = 0x1000; fn foo() { let layout = std::alloc::Layout::from_size_align(BUFFER_SIZE, BUFFER_ALIGN) .unwrap(); let buffer = std::alloc::alloc(layout); } ``` to ```rust const BUFFER_LAYOUT: std::alloc::Layout = unsafe { std::alloc::Layout::from_size_align_unchecked(0x2000, 0x1000) }; fn foo() { let buffer = std::alloc::alloc(BUFFER_LAYOUT); } ``` which (although `unsafe` is used) looks somewhat cleaner and is easier to read.

2019-04-23Rollup merge of #60169 - varkor:tidy-unnecessary-ignore-newline, r=kennytmMazdak Farrokhzad-3/+1
Warn when ignore-tidy-linelength is present, but no lines are too long It's easy for a `// ignore-tidy-linelength` to be added when there is a genuine need to ignore a file's line length, but then after refactoring the need is gone, but the tidy directive is not removed. This means that in the future, further editing may accidentally add unnecessarily long lines. This change forces `// ignore-tidy-linelength` to be used exactly when necessary, to make sure such changes are intentional.
