Use `Lit` rather than `P<Lit>` in `ast::ExprKind`. Because it results in fewer allocations and small speedups on some benchmarks.

2018-11-05Auto merge of #55451 - estebank:arg-doc, r=pnkfelixbors-3/+3
Custom diagnostic when trying to doc comment argument When writing ``` pub fn f( /// Comment id: u8, ) {} ``` Produce a targeted diagnostic ``` error: documentation comments cannot be applied to method arguments --> $DIR/fn-arg-doc-comment.rs:2:5 | LL | /// Comment | ^^^^^^^^^^^ doc comments are not allowed here ``` Fix #54801.

2018-11-01Rollup merge of #55558 - nnethercote:tweak-MatcherPos-matches, r=petrochenkovPietro Albini-6/+13
Tweak `MatcherPos::matches` These changes reduce instruction counts on `sentry-cli-check` incremental builds by up to 2%.
2018-11-01Rollup merge of #55542 - ljedrz:syntax_alloc_improvements, r=kennytmPietro Albini-0/+2
syntax: improve a few allocations Add 2 `reserve`s and a `with_capacity` where the final vector size is known.
2018-11-01Use `SmallVec` for the inner vectors in `MatcherPos::matches`.Nicholas Nethercote-5/+7
This avoids some allocations.
2018-11-01Share empty `Vec`s more within `MatcherPos::matches`.Nicholas Nethercote-4/+9
`create_matches` creates a `Vec<Rc<Vec<NamedMatch>>>`. Even though all the inner `Vec`s are empty, each one is created separately. This commit changes `create_matches` so it instead creates one empty inner `Vec`, and shares it. The commit also changes `MatcherPos::matches` to a boxed slice, because its length doesn't change.

2018-10-12Add missing lifetime fragment specifier to error message.Eric Huss-5/+6
A very minor issue, `lifetime` was missing from the error list. I left `literal` in the list, even though it is unstable. It looks like it may stabilize soon anyways.

2018-10-05Rollup merge of #54833 - abonander:issue-54441, r=petrochenkovPietro Albini-3/+1
make `Parser::parse_foreign_item()` return a foreign item or error Fixes `Parser::parse_foreign_item()` to follow the convention of `parse_trait_item()` and `parse_impl_item()` in that it *must* parse an item or return an error, and then the caller is responsible for detecting the closing delimiter. This prevents it from looping endlessly on an unexpected token in `ext/expand.rs` where it was also leaking memory by continually pushing to `Parser::expected_tokens` via `Parser::check_keyword()`. closes #54441 r? @petrochenkov cc @dtolnay
2018-10-05Auto merge of #54336 - petrochenkov:preuni, r=alexcrichtonbors-43/+30
resolve: Some refactorings in preparation for uniform paths 2.0 The main result is that in-scope resolution performed during macro expansion / import resolution is now consolidated in a single function (`fn early_resolve_ident_in_lexical_scope`), which can now be used for resolving first import segments as well when uniform paths are enabled. r? @ghost

The restrictions were introduced in https://github.com/rust-lang/rust/pull/54277 and no longer necessary now because legacy plugins are now expanded in usual left-to-right order
