2019-11-22Rollup merge of #66183 - Centril:empty-vis-trait-decl, r=petrochenkovMazdak Farrokhzad-0/+1
*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 ```

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-9/+12
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.

2019-09-29Rollup merge of #63492 - eddyb:cvarargs, r=nagisa,matthewjasperMazdak Farrokhzad-1/+0
Remove redundancy from the implementation of C variadics. This cleanup was first described in https://github.com/rust-lang/rust/issues/44930#issuecomment-497163539: * AST doesn't track `c_variadic: bool` anymore, relying solely on a trailing `CVarArgs` type in fn signatures * HIR doesn't have a `CVarArgs` anymore, relying solely on `c_variadic: bool` * same for `ty::FnSig` (see tests for diagnostics improvements from that) * `{hir,mir}::Body` have one extra argument than the signature when `c_variadic == true` * `rustc_typeck` and `rustc_mir::{build,borrowck}` need to give that argument the right type (which no longer uses a lifetime parameter, but a function-internal scope) * `rustc_target::abi::call` doesn't need special hacks anymore (since it never sees the `VaListImpl` now, it's all inside the body) r? @nagisa / @rkruppe cc @dlrobertson @oli-obk
