2019-11-26Rollup merge of #66719 - Mark-Simulacrum:int-normalization, r=CentrilTyler Mandry-0/+24
Store pointer width as u32 on Config This removes the dependency on IntTy, UintTy from Session. It's not obviously a win, but it seems a bit odd to store the AST IntTy/UintTy in Session, rather we store the pointer width as an integer and add normalization methods to IntTy and UintTy.
2019-11-25Auto merge of #66279 - cjgillot:hashstable, r=Zoxcbors-6/+16
Use proc-macro to derive HashStable everywhere Hello, A second proc-macro is added to derive HashStable for crates librustc depends on. This proc-macro `HashStable_Generic` (to bikeshed) allows to decouple code and strip much of librustc's boilerplate. Still, two implementations `Span` and `TokenKind` require to be placed in librustc. The latter only depends on the `bug` macro. Advise welcome on how to sever that link. A trait `StableHasingContextLike` has been introduced at each crate root, in order to handle those implementations which require librustc's very `StableHashingContext`. This overall effort allowed to remove the `impl_stable_hash_for` macro. Each commit passes the `x.py check`. I still have to double check there was no change in the implementation.

2019-11-22Rollup merge of #66183 - Centril:empty-vis-trait-decl, r=petrochenkovMazdak Farrokhzad-21/+29
*Syntactically* permit visibilities on trait items & enum variants Fixes #65041 Suppose we have `$vis trait_item` or `$vis enum_variant` and `$vis` is a `:vis` macro fragment. Before this PR, this would fail to parse. This is now instead allowed as per language team consensus in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. (See added tests for elaboration.) Moreover, we now also permit visibility modifiers on trait items & enum variants *syntactically* but reject them with semantic checks (in `ast_validation`): ```rust #[cfg(FALSE)] trait Foo { pub fn bar(); } // OK #[cfg(FALSE)] enum E { pub U } // OK ```

Merge repeated definitions Step forward on #66149 I may need further context to understand the need for a separate crate. Also, please tell me if you think of other definitions to merge.

We also sever syntax's dependency on rustc_target as a result. This should slightly improve pipe-lining. Moreover, some cleanup is done in related code.

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-3/+16
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.
