2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-1/+4
`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.

2019-06-24Auto merge of #62075 - Centril:guardless-match-arms, r=petrochenkovbors-4/+2
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
