This reduces duplication, thereby increasing expansion speed.

This is mostly removing stray ampersands, needless returns and lifetimes.

`Token::Interpolated(Nonterminal)` -> `Token::Interpolated(Rc<Nonterminal>)`.
2016-10-25Use `SmallVector` for `TtReader::stack`.Nicholas Nethercote-3/+4
This avoids 800,000 heap allocations when compiling html5ever. It requires tweaking `SmallVector` a little.

2016-07-06Auto merge of #34652 - jseyfried:fix_expansion_perf, r=nrcbors-2/+2
Fix expansion performance regression **syntax-[breaking-change] cc #31645** This fixes #34630 by reverting commit 5bf7970 of PR #33943, which landed in #34424. By removing the `Rc<_>` wrapping around `Delimited` and `SequenceRepetition` in `TokenTree`, 5bf7970 made cloning `TokenTree`s more expensive. While this had no measurable performance impact on the compiler's crates, it caused an order of magnitude performance regression on some macro-heavy code in the wild. I believe this is due to clones of `TokenTree`s in `macro_parser.rs` and/or `macro_rules.rs`. r? @nrc
2016-07-04Revert "Change `fold_tt` and `fold_tts` to take token trees by value ↵Jeffrey Seyfried-2/+2
(instead of by reference)" This reverts commit 5bf7970ac70b4e7781e7b2f3816720aa62fac6fd.
2016-07-03prefer `if let` to match with `None => {}` arm in some placesZack M. Davis-6/+3
This is a spiritual succesor to #34268/8531d581, in which we replaced a number of matches of None to the unit value with `if let` conditionals where it was judged that this made for clearer/simpler code (as would be recommended by Manishearth/rust-clippy's `single_match` lint). The same rationale applies to matches of None to the empty block.
2016-06-26Rollup merge of #33943 - jseyfried:libsyntax_cleanup, r=nrcJeffrey Seyfried-2/+2
Miscellaneous low priority cleanup in `libsyntax`.
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-7/+7
syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).
2016-06-23Move errors from libsyntax to its own crateJonathan Turner-1/+1
2016-06-21Refactored tokentrees into their own files in preparation for tokenstreams. ↵cgswords-7/+7
Modified tests to point to the new file now.
2016-06-14Change `fold_tt` and `fold_tts` to take token trees by value (instead of by ↵Jeffrey Seyfried-2/+2
reference)

2016-02-18Remove unnecessary explicit lifetime bounds.Corey Farwell-11/+11
These explicit lifetimes can be ommitted because of lifetime elision rules. Instances were found using rust-clippy.
2016-02-11[breaking-change] don't glob export ast::KleeneOp variantsOliver 'ker' Schneider-2/+2
2015-12-18Rollup merge of #30384 - nrc:diagnostics, r=@nikomatsakisManish Goregaokar-4/+4
Should make it possible to add JSON or HTML errors. Also tidies up a lot.

2015-12-17move error handling from libsyntax/diagnostics.rs to libsyntax/errors/*Nick Cameron-4/+4

2015-09-24Cleanup interfaces of Name, SyntaxContext and IdentVadim Petrochenkov-5/+5
Make sure Name, SyntaxContext and Ident are passed by value Make sure Idents don't serve as keys (or parts of keys) in maps, Ident comparison is not well defined
