2023-12-22Auto merge of #119097 - nnethercote:fix-EmissionGuarantee, r=compiler-errorsbors-10/+6
Fix `EmissionGuarantee` There are some problems with the `DiagCtxt` API related to `EmissionGuarantee`. This PR fixes them. r? `@compiler-errors`
2023-12-20Give `VariantData::Struct` named fields, to clairfy `recovered`.Alona Enraght-Moony-5/+5
2023-12-18Use `.into_diagnostic()` less.Nicholas Nethercote-10/+6
This commit replaces this pattern: ``` err.into_diagnostic(dcx) ``` with this pattern: ``` dcx.create_err(err) ``` in a lot of places. It's a little shorter, makes the error level explicit, avoids some `IntoDiagnostic` imports, and is a necessary prerequisite for the next commit which will add a `level` arg to `into_diagnostic`. This requires adding `track_caller` on `create_err` to avoid mucking up the output of `tests/ui/track-diagnostics/track4.rs`. It probably should have been there already.

`x clippy compiler -Aclippy::all -Wclippy::needless_borrow --fix`. Then I had to remove a few unnecessary parens and muts that were exposed now.

2023-11-08Rollup merge of #117282 - clubby789:recover-wrong-function-header, r=TaKO8KiGuillaume Gomez-3/+37
Recover from incorrectly ordered/duplicated function keywords Fixes #115714
2023-11-07Auto merge of #117297 - clubby789:fn-trait-missing-paren, r=TaKO8Kibors-0/+12
Give a better diagnostic for missing parens in Fn* bounds Fixes #108109 It would be nice to try and recover here, but I'm not sure it's worth the effort, especially as the bounds on the recovered function would be incorrect.
2023-11-03Auto merge of #117507 - nnethercote:rustc_span, r=Nilstriebbors-2/+2
`rustc_span` cleanups Just some things I found while looking over this crate. r? `@oli-obk`
2023-11-02Minimize `pub` usage in `source_map.rs`.Nicholas Nethercote-2/+2
Most notably, this commit changes the `pub use crate::*;` in that file to `use crate::*;`. This requires a lot of `use` items in other crates to be adjusted, because everything defined within `rustc_span::*` was also available via `rustc_span::source_map::*`, which is bizarre. The commit also removes `SourceMap::span_to_relative_line_string`, which is unused.

2023-08-30Rollup merge of #114704 - bvanjoi:fix-114636, r=compiler-errorsMatthias Krüger-13/+3
parser: not insert dummy field in struct Fixes #114636 This PR eliminates the dummy field, initially introduced in #113999, thereby enabling unrestricted use of `ident.unwrap()`. A side effect of this action is that we can only report the error of the first macro invocation field within the struct node. An alternative solution might be giving a virtual name to the macro, but it appears more complex.(https://github.com/rust-lang/rust/issues/114636#issuecomment-1670228715). Furthermore, if you think https://github.com/rust-lang/rust/issues/114636#issuecomment-1670228715 is a better solution, feel free to close this PR.

2023-08-03Remove `MacDelimiter`.Nicholas Nethercote-2/+2
It's the same as `Delimiter`, minus the `Invisible` variant. I'm generally in favour of using types to make impossible states unrepresentable, but this one feels very low-value, and the conversions between the two types are annoying and confusing. Look at the change in `src/tools/rustfmt/src/expr.rs` for an example: the old code converted from `MacDelimiter` to `Delimiter` and back again, for no good reason. This suggests the author was confused about the types.
