2019-10-14Rollup merge of #65363 - Centril:less-pprust, r=Mark-SimulacrumMazdak Farrokhzad-1/+1
Remove implicit dependencies on syntax::pprust Part of https://github.com/rust-lang/rust/pull/65324. The main goal here is to facilitate the eventual move of pprust out from libsyntax and because an AST definition typically should not depend on its pretty printer. r? @estebank
2019-10-13ast: remove implicit pprust dependency via Display.Mazdak Farrokhzad-1/+1
Instead just use `pprust::path_to_string(..)` where needed. This has two benefits: a) The AST definition is now independent of printing it. (Therefore we get closer to extracting a data-crate.) b) Debugging should be easier as program flow is clearer.

2019-10-02syntax: improve parameter without type suggestionsDavid Wood-8/+24
This commit improves the suggestions provided when function parameters do not have types: - A new suggestion is added for arbitrary self types, which suggests adding `self: ` before the type. - Existing suggestions are now provided when a `<` is found where a `:` was expected (previously only `,` and `)` or trait items), this gives suggestions in the case where the unnamed parameter type is generic in a free function. - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)` -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was found instead of `:`. - The ident will not be used for recovery when a `<` was found instead of `:`.

2019-09-23Auto merge of #64272 - Mark-Simulacrum:parallel-handler, r=estebankbors-7/+1
Refactor librustc_errors::Handler API This should be reviewed by-commit. The last commit moves all fields into an inner struct behind a single lock; this is done to prevent possible deadlocks in a multi-threaded compiler, as well as inconsistent state observation.

2019-09-05Bail out when encountering likely missing turbofish in parserEsteban Küber-1/+4
When encountering a likely intended turbofish without `::`, bubble up the diagnostic instead of emitting it to allow the parser to recover more gracefully and avoid uneccessary type errors that are likely to be wrong.

Allow attributes in formal function parameters Implements https://github.com/rust-lang/rust/issues/60406. This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made. **TODO** - [x] Forbid some built-in attributes. - [x] Expand cfg/cfg_attr
