2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-9/+12
`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.

2019-09-07Rollup merge of #63919 - matthewjasper:remove-gensymmed, r=petrochenkovMazdak Farrokhzad-4/+8
Use hygiene for AST passes AST passes are now able to have resolve consider their expansions as if they were opaque macros defined either in some module in the current crate, or a fake empty module with `#[no_implicit_prelude]`. * Add an ExpnKind for AST passes. * Remove gensyms in AST passes. * Remove gensyms in`#[test]`, `#[bench]` and `#[test_case]`. * Allow opaque macros to define tests. * Move tests for unit tests to their own directory. * Remove `Ident::{gensym, is_gensymed}` - `Ident::gensym_if_underscore` still exists. cc #60869, #61019 r? @petrochenkov

or-patterns: Uniformly use `PatKind::Or` in AST & Fix/Cleanup resolve Following up on work in https://github.com/rust-lang/rust/pull/63693 and https://github.com/rust-lang/rust/pull/61708, in this PR we: - Uniformly use `PatKind::Or(...)` in AST: - Change `ast::Arm.pats: Vec<P<Pat>>` => `ast::Arm.pat: P<Pat>` - Change `ast::ExprKind::Let.0: Vec<P<Pat>>` => `ast::ExprKind::Let.0: P<Pat>` - Adjust `librustc_resolve/late.rs` to correctly handle or-patterns at any level of nesting as a result. In particular, the already-bound check which rejects e.g. `let (a, a);` now accounts for or-patterns. The consistency checking (ensures no missing bindings and binding mode consistency) also now accounts for or-patterns. In the process, a bug was found in the current compiler which allowed: ```rust enum E<T> { A(T, T), B(T) } use E::*; fn foo() { match A(0, 1) { B(mut a) | A(mut a, mut a) => {} } } ``` The new algorithms took a few iterations to get right. I tried several clever schemes but ultimately a version based on a stack of hashsets and recording product/sum contexts was chosen since it is more clearly correct. - Clean up `librustc_resolve/late.rs` by, among other things, using a new `with_rib` function to better ensure stack dicipline. - Do not push the change in AST to HIR for now to avoid doing too much in this PR. To cope with this, we introduce a temporary hack in `rustc::hir::lowering` (clearly marked in the diff). cc https://github.com/rust-lang/rust/issues/54883 cc @dlrobertson @matthewjasper r? @petrochenkov
