2019-08-10resolve: Move late resolution into a separate visitorVadim Petrochenkov-8/+6
Move `Resolver` fields specific to late resolution to the new visitor. The `current_module` field from `Resolver` is replaced with two `current_module`s in `LateResolutionVisitor` and `BuildReducedGraphVisitor`. Outside of those visitors `current_module` is replaced by passing `parent_scope` to more functions and using the parent module from it. Visibility resolution no longer have access to later resolution methods and has to use early resolution, so its diagnostics in case of errors regress slightly.

2019-07-24Rollup merge of #62772 - estebank:trait-bound, r=matthewjasperMazdak Farrokhzad-3/+5
Suggest trait bound on type parameter when it is unconstrained Given ``` trait Foo { fn method(&self) {} } fn call_method<T>(x: &T) { x.method() } ``` suggest constraining `T` with `Foo`. Fix #21673, fix #41030.
2019-07-19Auto merge of #62684 - petrochenkov:scopevisit, r=davidtwcobors-23/+6
resolve: Improve candidate search for unresolved macro suggestions Use same scope visiting machinery for both collecting suggestion candidates and actually resolving the names. The PR is better read in per-commit fashion with whitespace changes ignored (the first commit in particular moves some code around). This should be the last pre-requisite for https://github.com/rust-lang/rust/pull/62086. r? @davidtwco

2019-07-18resolve: Use `feature(custom_attribute)` fallback only if the feature is enabledVadim Petrochenkov-23/+6
Normally `#![feature(...)]` shouldn't change behavior, but custom attributes in particular are in the process of retirement, and we should not produce a message telling to enable them. It also helps with unifying diagnostics for unresolved macros.

2019-05-31Add more detail to type inference errorEsteban Küber-2/+2
When encountering code where type inference fails, add more actionable information: ``` fn main() { let foo = Vec::new(); } ``` ``` error[E0282]: type annotations needed for `std::vec::Vec<_>` --> $DIR/vector-no-ann.rs:2:16 | LL | let foo = Vec::new(); | --- ^^^^^^^^ cannot infer type for `T` | | | consider giving `foo` the type `std::vec::Vec<_>` with the type parameter `T` specified ``` We still need to modify type printing to optionally accept a `TypeVariableTable` in order to properly print `std::vec::Vec<T>`. CC #25633.
