2020-02-01Auto merge of #68698 - tmiasko:catch-panic, r=Amanieubors-0/+26
Remove incorrect debug assertions from catch_unwind Previously the debug assertions in the implementation of catch_unwind used to verify consistency of the panic count by checking that the count is zero just before leaving the function. This incorrectly assumed that no panic was in progress when entering `catch_unwind`. Fixes #68696.
2020-01-31Auto merge of #68080 - varkor:declared-here, r=petrochenkovbors-42/+42
Address inconsistency in using "is" with "declared here" "is" was generally used for NLL diagnostics, but not other diagnostics. Using "is" makes the diagnostics sound more natural and readable, so it seems sensible to commit to them throughout. r? @Centril

2020-01-30Auto merge of #68325 - faern:move-numeric-consts-to-associated-consts-step1, ↵bors-18/+0
r=LukasKalbertodt Move numeric consts to associated consts step1 A subset of #67913. Implements the first step of RFC https://github.com/rust-lang/rfcs/pull/2700 This PR adds the new constants as unstable constants and defines the old ones in terms of the new ones. Then fix a tiny bit of code that started having naming collisions because of the new assoc consts. Removed a test that did not seem relevant any longer. Since doing just `u8::MIN` should now indeed be valid.

Rollup of 6 pull requests Successful merges: - #67956 (Detail transitive containment in E0588 diagnostic) - #68153 (resolve: Point at the private item definitions in privacy errors) - #68195 (Account for common `impl Trait`/`dyn Trait` return type errors) - #68288 (Fix some of the rustfmt fallout in Miri) - #68292 (don't clone types that are copy) - #68301 (Don't propagate __RUST_TEST_INVOKE to subprocess) Failed merges: r? @ghost
2020-01-17Rollup merge of #68195 - estebank:impl-trait-2000, r=CentrilDylan DPC-0/+9
Account for common `impl Trait`/`dyn Trait` return type errors - When all return paths have the same type, suggest `impl Trait`. - When all return paths implement the expected `trait`, suggest `Box<dyn Trait>` and mention using an `enum`. - When multiple different types are returned and `impl Trait` is expected, extend the explanation. - When return type is `impl Trait` and the return paths do not implement `Trait`, point at the returned values. - Split `src/librustc/traits/error_reporting.rs` into multiple files to keep size under control. Fix #68110, cc #66523.

2020-01-16Rollup merge of #68096 - varkor:diagnostic-cleanup, r=CentrilDylan DPC-6/+6
Clean up some diagnostics by making them more consistent In general: - Diagnostic should start with a lowercase letter. - Diagnostics should not end with a full stop. - Ellipses contain three dots. - Backticks should encode Rust code. I also reworded a couple of messages to make them read more clearly. It might be sensible to create a style guide for diagnostics, so these informal conventions are written down somewhere, after which we could audit the existing diagnostics. r? @Centril
