2020-02-02Rollup merge of #68764 - Centril:self-semantic, r=petrochenkovMazdak Farrokhzad-18/+7
parser: syntactically allow `self` in all `fn` contexts Part of https://github.com/rust-lang/rust/pull/68728. `self` parameters are now *syntactically* allowed as the first parameter irrespective of item context (and in function pointers). Instead, semantic validation (`ast_validation`) is used. r? @petrochenkov

2020-01-12Rollup merge of #68108 - varkor:chained-comparison-suggestions, r=CentrilMazdak Farrokhzad-13/+70
Add suggestions when encountering chained comparisons Ideally, we'd also prevent the type error, which is just extra noise, but that will require moving the error from the parser, and I think the suggestion makes things clear enough for now. Fixes https://github.com/rust-lang/rust/issues/65659.
2020-01-11Rollup merge of #68084 - estebank:ice-68000, r=varkorMazdak Farrokhzad-7/+4
Do not ICE on unicode next point Use `shrink_to_hi` instead of `next_point` and fix `next_point`. Fix #68000, fix #68091, fix #68092.

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

2019-11-22Rollup merge of #66183 - Centril:empty-vis-trait-decl, r=petrochenkovMazdak Farrokhzad-20/+0
*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 ```
