2021-02-05Add test for #75158Ömer Sinan Ağacan-0/+20
Closes #75158
2021-02-04typeck: Emit structured suggestions for tuple struct syntaxCamelid-2/+2
And tuple variant syntax, but that didn't fit in the subject :) Now the fact that these are suggestions is exposed both to the layout engine and to IDEs and rustfix for automatic application.

2021-01-28Auto merge of #81055 - matthewjasper:non-fatal-overflow, r=nikomatsakisbors-1/+2
Make hitting the recursion limit in projection non-fatal This change was originally made in #80246 to avoid future (effectively) infinite loop bugs in projections, but wundergraph relies on rustc recovering here. cc #80953 r? `@nikomatsakis`

2021-01-28Auto merge of #81149 - Aaron1011:feature/better-no-method-found-err, r=estebankbors-35/+35
Avoid describing a method as 'not found' when bounds are unsatisfied Fixes #76267 When there is a single applicable method candidate, but its trait bounds are not satisfied, we avoid saying that the method is "not found". Insted, we update the error message to directly mention which bounds are not satisfied, rather than mentioning them in a note.

2021-01-23Auto merge of #80065 - b-naber:parse-angle-arg-diagnostics, r=petrochenkovbors-6/+9
Improve diagnostics when parsing angle args https://github.com/rust-lang/rust/pull/79266 introduced parsing of generic arguments in associated type constraints, this however resulted in possibly very confusing error messages in cases in which closing angle brackets were missing such as in `Vec<(u32, _, _) = vec![]`, which outputs an incorrectly parsed equality constraint error, as noted by `@cynecx.` This PR tries to provide better error messages in such cases. r? `@petrochenkov`

2021-01-14Auto merge of #79328 - c410-f3r:hir-if, r=matthewjasperbors-0/+2
Reintroduce hir::ExprKind::If Basically copied and paste #59288/https://github.com/rust-lang/rust-clippy/pull/4080 with some modifications. The vast majority of tests were fixed and now there are only a few remaining.

2021-01-13Auto merge of #77524 - Patryk27:fixes/66228, r=estebankbors-28/+102
Rework diagnostics for wrong number of generic args (fixes #66228 and #71924) This PR reworks the `wrong number of {} arguments` message, so that it provides more details and contextual hints.

For example, this code: struct S(i32, f32); let S(x) = S(0, 1.0); will make the compiler suggest either: let S(x, _) = S(0, 1.0); or: let S(x, ..) = S(0, 1.0);

2021-01-12Rollup merge of #80324 - Aaron1011:loop-move-fn-self, r=oli-obkYuki Okushi-3/+3
Explain method-call move errors in loops PR #73708 added a more detailed explanation of move errors that occur due to a call to a method that takes `self`. This PR extends that logic to work when a move error occurs due to a method call in the previous iteration of a loop.

Allow references to interior mutable data behind a feature gate supercedes #80373 by simply not checking for interior mutability on borrows of locals that have `StorageDead` and thus can never be leaked to the final value of the constant tracking issue: https://github.com/rust-lang/rust/issues/80384 r? `@RalfJung`
