2019-08-17initial implementation of or-pattern parsingDan Robertson-4/+40

2019-08-15hygiene: `ExpnInfo` -> `ExpnData`Vadim Petrochenkov-1/+1
For naming consistency with everything else in this area
2019-08-15syntax_pos: Remove the duplicate global editionVadim Petrochenkov-29/+6
It was introduced to avoid going through `hygiene_data`, but now it's read only once, when `ParseSess` is created, so going through a lock is ok.
2019-08-15hygiene: Remove `Option`s from functions returning `ExpnInfo`Vadim Petrochenkov-1/+0
The expansion info is not optional and should always exist
2019-08-15`Ident::with_empty_ctxt` -> `Ident::with_dummy_span`Vadim Petrochenkov-1/+1
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.
2019-08-15syntax_pos: `NO_EXPANSION`/`SyntaxContext::empty()` -> `SyntaxContext::root()`Vadim Petrochenkov-11/+10
For consistency with `ExpnId::root`. Also introduce a helper `Span::with_root_ctxt` for creating spans with `SyntaxContext::root()` context

2019-08-14Rollup merge of #62984 - nathanwhit:extra_semi_lint, r=varkorMazdak Farrokhzad-1/+16
Add lint for excess trailing semicolons Closes #60876. A caveat (not necessarily a negative, but something to consider) with this implementation is that excess semicolons after return/continue/break now also cause an 'unreachable statement' warning. For the following example: ``` fn main() { extra_semis(); } fn extra_semis() -> i32 { let mut sum = 0;;; for i in 0..10 { if i == 5 { continue;; } else if i == 9 { break;; } else { sum += i;; } } return sum;; } ``` The output is: ``` warning: unnecessary trailing semicolons --> src/main.rs:5:21 | 5 | let mut sum = 0;;; | ^^ help: remove these semicolons | = note: `#[warn(redundant_semicolon)]` on by default warning: unnecessary trailing semicolon --> src/main.rs:8:22 | 8 | continue;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:10:19 | 10 | break;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:12:22 | 12 | sum += i;; | ^ help: remove this semicolon warning: unnecessary trailing semicolon --> src/main.rs:15:16 | 15 | return sum;; | ^ help: remove this semicolon warning: unreachable statement --> src/main.rs:8:22 | 8 | continue;; | ^ | = note: `#[warn(unreachable_code)]` on by default warning: unreachable statement --> src/main.rs:10:19 | 10 | break;; | ^ warning: unreachable statement --> src/main.rs:15:16 | 15 | return sum;; | ^ ```
