2019-12-30Rollup merge of #64273 - petrochenkov:stabattrmod, r=CentrilYuki Okushi-7/+4
Stabilize attribute macros on inline modules While still gating non-inline modules in proc macro input. Split from https://github.com/rust-lang/rust/pull/63931 cc https://github.com/rust-lang/rust/issues/54727
2019-12-29Auto merge of #67112 - Centril:expr-polish, r=estebankbors-4/+2
Refactor expression parsing thoroughly Based on https://github.com/rust-lang/rust/pull/66994 together with which this has refactored basically the entirety of `expr.rs`. r? @estebank

Merge `TraitItem` & `ImplItem into `AssocItem` In this PR we: - Merge `{Trait,Impl}Item{Kind?}` into `AssocItem{Kind?}` as discussed in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. - This is done by using the cover grammar of both forms. - In particular, it requires that we syntactically allow (under `#[cfg(FALSE)]`): - `default`ness on `trait` items, - `impl` items without a body / definition (`const`, `type`, and `fn`), - and associated `type`s in `impl`s with bounds, e.g., `type Foo: Ord;`. - The syntactic restrictions are replaced by semantic ones in `ast_validation`. - Move syntactic restrictions around C-variadic parameters from the parser into `ast_validation`: - `fn`s in all contexts now syntactically allow `...`, - `...` can occur anywhere in the list syntactically (`fn foo(..., x: usize) {}`), - and `...` can be the sole parameter (`fn foo(...) {}`. r? @petrochenkov

2019-12-12Remove the `DelimSpan` from `NamedMatch::MatchedSeq`.Nicholas Nethercote-20/+11
Because it's unused. This then allows the removal of `MatcherPos::sp_open`. It's a tiny perf win, reducing instruction counts by 0.1% - 0.2% on a few benchmarks.

Ast address-of This is the parts of #64588 that don't affect MIR. If an address-of expression makes it to MIR lowering we error and lower to the best currently expressible approximation to limit further errors. r? @Centril

*Syntactically* permit visibilities on trait items & enum variants Fixes #65041 Suppose we have `$vis trait_item` or `$vis enum_variant` and `$vis` is a `:vis` macro fragment. Before this PR, this would fail to parse. This is now instead allowed as per language team consensus in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. (See added tests for elaboration.) Moreover, we now also permit visibility modifiers on trait items & enum variants *syntactically* but reject them with semantic checks (in `ast_validation`): ```rust #[cfg(FALSE)] trait Foo { pub fn bar(); } // OK #[cfg(FALSE)] enum E { pub U } // OK ```
