Because it's unused. This then allows the removal of `MatcherPos::sp_open`. It's a tiny perf win, reducing instruction counts by 0.1% - 0.2% on a few benchmarks.

*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 ```

2019-11-07Rollup merge of #65974 - Centril:matcher-friendly-gating, r=petrochenkovMazdak Farrokhzad-2/+15
A scheme for more macro-matcher friendly pre-expansion gating Pre-expansion gating will now avoid gating macro matchers that did not result in `Success(...)`. That is, the following is now OK despite `box 42` being a valid `expr` and that form being pre-expansion gated: ```rust macro_rules! m { ($e:expr) => { 0 }; // This fails on the input below due to `, foo`. (box $e:expr, foo) => { 1 }; // Successful matcher, we should get `2`. } fn main() { assert_eq!(1, m!(box 42, foo)); } ``` Closes https://github.com/rust-lang/rust/issues/65846. r? @petrochenkov cc @Mark-Simulacrum
2019-11-07syntax: use distinct FloatTy from rustc_target.Mazdak Farrokhzad-1/+0
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-10/+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.
2019-11-06Remove unnecessary `Deref` impl for `Attribute`.Nicholas Nethercote-6/+6
This kind of thing just makes the code harder to read.

2019-11-06Rollup merge of #65973 - eddyb:caller-location-panic, r=petrochenkovMazdak Farrokhzad-12/+1
caller_location: point to macro invocation sites, like file!/line!, and use in core::panic!. The main change here is to `core::panic!`, trying to fix this remaining regression: https://github.com/rust-lang/rust/pull/65927#issuecomment-547625147 However, in order for `caller_location` to be usable from macros the same way `file!()`/`line!()` are, it needs to have the same behavior (of extracting the macro invocation site `Span` and using that). Arguably we would've had to do this at some point anyway, if we want to use `#[track_caller]` to replace the `file!()`/`line!()` uses from macros, but I'm not sure the RFC mentions this at all. r? @petrochenkov cc @anp @nnethercote

2019-11-06Rollup merge of #66054 - petrochenkov:delspan, r=estebankMazdak Farrokhzad-20/+10
syntax: Avoid span arithmetic for delimiter tokens The +/-1 logic is from the time where the whole group had a single span and the delimiter spans had to be calculated from it. Now the delimiters have their own spans which are constructed by lexer or proc macro API and can be used directly. If those spans are not perfect, then it should be fixed by tweaking the corresponding lexer logic rather than by trying to add or substract `1` from the span boundaries. Fixes https://github.com/rust-lang/rust/issues/62524 r? @estebank
