Suggest adding a `?Sized` bound if appropriate on E0599 by inspecting the HIR Generics. (Fix #98539)
2022-07-01Auto merge of #93967 - cjgillot:short-struct-span, r=petrochenkovbors-6/+4
Shorten def_span for more items. The `def_span` query only returns the signature span for functions. Struct/enum/union definitions can also have a very long body. This PR shortens the associated span.

2022-07-01Auto merge of #98402 - cjgillot:undead, r=michaelwoeristerbors-10/+10
Rewrite dead-code pass to avoid fetching HIR. This allows to get a more uniform handling of spans, and to simplify the grouping of diagnostics for variants and fields.
2022-06-27Rollup merge of #97780 - compiler-errors:field-wfcheck-before-sized, r=jackh726Matthias Krüger-15/+5
Check ADT field is well-formed before checking it is sized Fixes #96810. There is one diagnostics regression, in [`src/test/ui/generic-associated-types/bugs/issue-80626.stderr`](https://github.com/rust-lang/rust/pull/97780/files#diff-53795946378e78a0af23a10277c628ff79091c18090fdc385801ee70c1ba6963). I am not super concerned about it, since it's GAT related. We _could_ fix it, possibly by using the `FieldSized` obligation cause code instead of `BuiltinDerivedObligation`. But that would require changing `Sized` trait confirmation and the `adt_sized_constraint` query.

danielhenrymantilla:diagnostics/union-drop-suggest-copy-bound-alternative, r=davidtwco [diagnostics] Add mentions to `Copy` types being valid for `union` fields This came up from some user on Discord which was using a `T : PrimitiveInt` generic type, and they wanted to use in a `union`. Rather than adding a `Copy` bound, they started pondering about the `ManuallyDrop<T>` road, and how to correctly use `unsafe` to perform the drops. <img width="648" alt="Screen Shot 2022-02-15 at 22 28 34" src="https://user-images.githubusercontent.com/9920355/154152496-8f9be74b-ad59-4724-8f9e-48b446774e06.png"> - [Discord link](https://discord.com/channels/442252698964721669/443150878111694848/943092778534072320) So, it seemed like the error message for types with potential drop glue on `union` fields could be improved to also mention the `Copy` alternative, since in many cases where `union`s are concerned, people are dealing with PODs / `Copy` types anyways 🙂 ___ ``@rustbot`` modify labels: +A-diagnostics +D-terse

2021-11-20Point at source of trait bound obligations in more placesEsteban Kuber-12/+12
Be more thorough in using `ItemObligation` and `BindingObligation` when evaluating obligations so that we can point at trait bounds that introduced unfulfilled obligations. We no longer incorrectly point at unrelated trait bounds (`substs-ppaux.verbose.stderr`). In particular, we now point at trait bounds on method calls. We no longer point at "obvious" obligation sources (we no longer have a note pointing at `Trait` saying "required by a bound in `Trait`", like in `associated-types-no-suitable-supertrait*`). Address part of #89418.

2021-08-25Fix debugger stepping behavior around `match` expressionsWesley Wiser-2/+2
Previously, we would set up the source lines for `match` expressions so that the code generated to perform the test of the scrutinee was matched to the line of the arm that required the test and then jump from the arm block to the "next" block was matched to all of the lines in the `match` expression. While that makes sense, it has the side effect of causing strange stepping behavior in debuggers. I've changed the source information so that all of the generated tests are sourced to `match {scrutinee}` and the jumps are sourced to the last line of the block they are inside. This resolves the weird stepping behavior in all debuggers and resolves some instances of "ambiguous symbol" errors in WinDbg preventing the user from setting breakpoints at `match` expressions.
