2018-04-19Avoid allocating when parsing \u{...} literals.Nicholas Nethercote-2/+10
`char_lit` uses an allocation in order to ignore '_' chars in \u{...} literals. This patch changes it to not do that by processing the chars more directly. This improves various rustc-perf benchmark measurements by up to 6%, particularly regex, futures, clap, coercions, hyper, and encoding.

2018-01-04rustc: use {U,I}size instead of {U,I}s shorthands.Eduard-Mihai Burtescu-2/+2
2017-12-22Auto merge of #46732 - estebank:silence-recovered-blocks, r=petrochenkovbors-0/+1
Do not emit type errors on recovered blocks When a parse error occurs on a block, the parser will recover and create a block with the statements collected until that point. Now a flag stating that a recovery has been performed in this block is propagated so that the type checker knows that the type of the block (which will be identified as `()`) shouldn't be checked against the expectation to reduce the amount of irrelevant diagnostic errors shown to the user. Fix #44579.

2017-12-21Add GenericParam, refactor Generics in ast, hir, rustdocJonas Platte-3/+2
The Generics now contain one Vec of an enum for the generic parameters, rather than two separate Vec's for lifetime and type parameters. Additionally, places that previously used Vec<LifetimeDef> now use Vec<GenericParam> instead.

2017-07-30default binding modes: add pat_binding_modesTobias Schottdorf-7/+8
This PR kicks off the implementation of the [default binding modes RFC][1] by introducing the `pat_binding_modes` typeck table mentioned in the [mentoring instructions][2]. `pat_binding_modes` is populated in `librustc_typeck/check/_match.rs` and used wherever the HIR would be scraped prior to this PR. Unfortunately, one blemish, namely a two callers to `contains_explicit_ref_binding`, remains. This will likely have to be removed when the second part of [1], the `pat_adjustments` table, is tackled. Appropriate comments have been added. See #42640. [1]: https://github.com/rust-lang/rfcs/pull/2005 [2]: https://github.com/rust-lang/rust/issues/42640#issuecomment-313535089

Add Span to ast::WhereClause This PR adds `Span` field to `ast::WhereClause`. The motivation here is to make rustfmt's life easier when recovering comments before and after where clause. r? @nrc
2017-07-28syntax: Capture a `TokenStream` when parsing itemsAlex Crichton-1/+8
This is then later used by `proc_macro` to generate a new `proc_macro::TokenTree` which preserves span information. Unfortunately this isn't a bullet-proof approach as it doesn't handle the case when there's still other attributes on the item, especially inner attributes. Despite this the intention here is to solve the primary use case for procedural attributes, attached to functions as outer attributes, likely bare. In this situation we should be able to now yield a lossless stream of tokens to preserve span information.

2017-05-18Add an option to the parser to avoid parsing out of line modulesNick Cameron-2/+23
This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.

`TokenStream`-based attributes, paths in attribute and derive macro invocations This PR - refactors `Attribute` to use `Path` and `TokenStream` instead of `MetaItem`. - supports macro invocation paths for attribute procedural macros. - e.g. `#[::foo::attr_macro] struct S;`, `#[cfg_attr(all(), foo::attr_macro)] struct S;` - supports macro invocation paths for derive procedural macros. - e.g. `#[derive(foo::Bar, super::Baz)] struct S;` - supports arbitrary tokens as arguments to attribute procedural macros. - e.g. `#[foo::attr_macro arbitrary + tokens] struct S;` - supports using arbitrary tokens in "inert attributes" with derive procedural macros. - e.g. `#[derive(Foo)] struct S(#[inert arbitrary + tokens] i32);` where `#[proc_macro_derive(Foo, attributes(inert))]` r? @nrc
