2018-11-08Rollup merge of #55777 - nnethercote:less-P-in-ast, r=petrochenkovMark Rousskov-6/+6
Use `Lit` rather than `P<Lit>` in `ast::ExprKind`. Because it results in fewer allocations and small speedups on some benchmarks.

2018-11-06Rollup merge of #55601 - petrochenkov:featissue, r=pnkfelixkennytm-19/+8
Fix tracking issue numbers for some unstable features And also remove deprecated unstable `#[panic_implementation]` attribute that was superseded by stable `#[panic_handler]` and doesn't have an open tracking issue.
2018-11-05Auto merge of #55451 - estebank:arg-doc, r=pnkfelixbors-20/+65
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.
2018-11-04Auto merge of #55455 - estebank:expected-descr, r=michaelwoeristerbors-24/+26

2018-11-04Auto merge of #54861 - rep-nop:find_main_in_doctest, r=estebankbors-9/+81
rustdoc: Replaces fn main search and extern crate search with proper parsing during doctests. Fixes #21299. Fixes #33731. Let me know if there's any additional changes you'd like made!

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.

2018-10-29Rollup merge of #55384 - nnethercote:better-integer_lit-float_lit, ↵Pietro Albini-4/+19
r=michaelwoerister Avoid unnecessary allocations in `float_lit` and `integer_lit`. This commit avoids an allocation when parsing any float and integer literals that don't involved underscores. This reduces the number of allocations done for the `tuple-stress` benchmark by 10%, reducing its instruction count by just under 1%.

Before parsing argument names and types, try to consume an incorrectly included doc comment or attribute in order to recover and continue parsing the rest of the fn definition.
2018-10-28Auto merge of #55192 - cramertj:nested-mod, r=petrochenkovbors-0/+11
Fix ordering of nested modules in non-mod.rs mods Flatten relative offset into directory path before adding inline (mod x { ... }) module names to the current directory path. Fix #55094
2018-10-27feature-gate lint reasonsZack M. Davis-0/+3
We take stability seriously, so we shy away from making even seemingly "trivial" features insta-stable.
