2019-01-20Auto merge of #57651 - JohnTitor:give-char-type, r=estebankbors-0/+1
Implement new literal type `Err` Fixes #57384 I removed `return Ok`, otherwise, two errors occur. Any solutions? r? @estebank

2019-01-14Remove `ThinTokenStream`.Nicholas Nethercote-1/+1
`TokenStream` is now almost identical to `ThinTokenStream`. This commit removes the latter, replacing it with the former.
2019-01-08Make `TokenStream` less recursive.Nicholas Nethercote-1/+1
`TokenStream` is currently recursive in *two* ways: - the `TokenTree` variant contains a `ThinTokenStream`, which can contain a `TokenStream`; - the `TokenStream` variant contains a `Vec<TokenStream>`. The latter is not necessary and causes significant complexity. This commit replaces it with the simpler `Vec<(TokenTree, IsJoint)>`. This reduces complexity significantly. In particular, `StreamCursor` is eliminated, and `Cursor` becomes much simpler, consisting now of just a `TokenStream` and an index. The commit also removes the `Extend` impl for `TokenStream`, because it is only used in tests. (The commit also removes those tests.) Overall, the commit reduces the number of lines of code by almost 200.

2018-12-12Rename `TokenStream::concat` and remove `TokenStream::concat_rc_vec`.Nicholas Nethercote-1/+1
`TokenStream::new` is a better name for the former, and the latter is now just equivalent to `TokenStream::Stream`.
2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-17/+15
Because it's an extra type layer that doesn't really help; in a couple of places it actively gets in the way, and overall removing it makes the code nicer. It does, however, move `tokenstream::TokenTree` further away from the `TokenTree` in `quote.rs`. More importantly, this change reduces the size of `TokenStream` from 48 bytes to 40 bytes on x86-64, which is enough to slightly reduce instruction counts on numerous benchmarks, the best by 1.5%. Note that `open_tt` and `close_tt` have gone from being methods on `Delimited` to associated methods of `TokenTree`.

2018-12-02Remove not used `DotEq` tokenyui-knk-1/+0
Currently libproc_macro does not use `DotEq` token. https://github.com/rust-lang/rust/pull/49545 changed libproc_macro to not generate `DotEq` token.
2018-11-08Rollup merge of #55777 - nnethercote:less-P-in-ast, r=petrochenkovMark Rousskov-2/+2
Use `Lit` rather than `P<Lit>` in `ast::ExprKind`. Because it results in fewer allocations and small speedups on some benchmarks.

This reduces the size of `Token` from 32 bytes to 24 bytes on 64-bit platforms.

2017-12-28Resurrecting #33135Michael Hewson-0/+7
Started rebasing @sgrif's PR #33135 off of current master. (Well, actually merging it into a new branch based off current master.) The following files still need to be fixed or at least reviewed: - `src/libsyntax/ext/tt/macro_parser.rs`: calls `Parser::parse_lifetime`, which doesn't exist anymore - `src/libsyntax/parse/parser.rs`: @sgrif added an error message to `Parser::parse_lifetime`. Code has since been refactored, so I just took it out for now. - `src/libsyntax/ext/tt/transcribe.rs`: This code has been refactored bigtime. Not sure whether @sgrif's changes here are still necessary. Took it out for this commit.

Fix #35829 (`quote!()` does not handle `br#"…"#`) Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`) * Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`. * Refactored the match statement to allow it to complain loudly on any unhandled token. * Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.
