2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-1/+1
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`.

And make them x86_64-only so they can use `==` instead of `<=`.

2018-11-08Use `Lit` rather than `P<Lit>` in `ast::ExprKind`.Nicholas Nethercote-1/+1
Because it results in fewer allocations and small speedups on some benchmarks.

2018-09-27Auto merge of #52319 - tinco:issue_12590, r=pnkfelixbors-0/+2
Track whether module declarations are inline (fixes #12590) To track whether module declarations are inline I added a field `inline: bool` to `ast::Mod`. The main use case is for pretty to know whether it should render the items associated with the module, but perhaps there are use cases for this information to not be forgotten in the AST.

refactor match guard This is the first step to implement RFC 2294: if-let-guard. Tracking issue: https://github.com/rust-lang/rust/issues/51114 The second step should be introducing another variant `IfLet` in the Guard enum. I separated them into 2 PRs for the convenience of reviewers. r? @petrochenkov

2018-08-14Auto merge of #53085 - ljedrz:cleanup_syntax_structures, r=ljedrzbors-1/+1
Move SmallVector and ThinVec out of libsyntax - move `libsyntax::util::SmallVector` tests to `librustc_data_structures::small_vec` - remove `libsyntax::util::SmallVector` - move `libsyntax::util::thin_vec` to `librustc_data_structures::thin_vec` Other than moving these data structures where they belong it allows modules using `SmallVector<T>` (`SmallVec<[T; 1]>`) to specify their own length (e.g. 8 or 32) independently from `libsyntax`.

2018-06-26inclusive range syntax lint (`...` → `..=`)Zack M. Davis-1/+1
Our implementation ends up changing the `PatKind::Range` variant in the AST to take a `Spanned<RangeEnd>` instead of just a `RangeEnd`, because the alternative would be to try to infer the span of the range operator from the spans of the start and end subexpressions, which is both hideous and nontrivial to get right (whereas getting the change to the AST right was a simple game of type tennis). This is concerning #51043.
2018-06-26migrate codebase to `..=` inclusive range patternsZack M. Davis-2/+2
These were stabilized in March 2018's #47813, and are the Preferred Way to Do It going forward (q.v. #51043).
2018-06-21async await desugaring and testsTaylor Cramer-2/+22
2018-06-21Parse async fn header.Without Boats-5/+32
This is gated on edition 2018 & the `async_await` feature gate. The parser will accept `async fn` and `async unsafe fn` as fn items. Along the same lines as `const fn`, only `async unsafe fn` is permitted, not `unsafe async fn`.The parser will not accept `async` functions as trait methods. To do a little code clean up, four fields of the function type struct have been merged into the new `FnHeader` struct: constness, asyncness, unsafety, and ABI. Also, a small bug in HIR printing is fixed: it previously printed `const unsafe fn` as `unsafe const fn`, which is grammatically incorrect.
