2023-01-30errors: add `emit_note`/`create_note` on `Handler`David Wood-0/+11
Support for emission of notes was added in f8ebc72 but `emit_note` and `create_note` functions weren't added to `Handler`. Signed-off-by: David Wood <david.wood@huawei.com>

Improve fluent error messages These have been really frustrating me while migrating diagnostics.
2023-01-11Rollup merge of #106321 - compiler-errors:delayed-bug-backtrace, r=Nilstriebnils-23/+15
Collect and emit proper backtraces for `delay_span_bug`s This is a follow-up to #106317, which addresses this comment (https://github.com/rust-lang/rust/issues/106267#issuecomment-1367507507) which notes that `delay_span_bug`s' backtraces are nonsense. Captures and emits the backtrace of the delayed span bug when it's *created*, rather than using the backtrace of the place where delayed bugs are flushed. --- To test, I delayed a span bug during HIR typeck, specifically in `typeck_with_fallback`... Before, note `flush_delayed` on frame 18. This is at the end of the compilation session, far from where the bug is being delayed. ``` error: internal compiler error: test --> /home/ubuntu/test.rs:1:1 | 1 | fn main() {} | ^^^^^^^^^ | = note: delayed at compiler/rustc_hir_typeck/src/lib.rs:196:14 thread 'rustc' panicked at 'Box<dyn Any>', compiler/rustc_errors/src/lib.rs:1634:13 stack backtrace: 0: 0x7f9c3ec69dd1 -

JhonnyBillM:migrate-codegen-ssa-to-diagnostics-structs-pt3, r=davidtwco Migrate `codegen_ssa` to diagnostics structs - [Part 3] Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates: 1. [`rustc_middle::mir::interpret::InterpError`](https://github.com/rust-lang/rust/blob/b6097f2e1b2ca62e188ba53cf43bd66b06b36915/compiler/rustc_middle/src/mir/interpret/error.rs#L475): I saw `rustc_middle` is unassigned, I am open to take this work. 2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](https://github.com/rust-lang/rust/commit/9a31b3cdda78a2c0891828254fe9886e0a1cfd16) of this PR, but would like to know the team's preference on how we should keep replacing the other macros: 2.1. Update macros to expect a `Diagnostic` 2.2. Remove macros and expand the code on each use. See [some examples of the different options in this experimental commit](https://github.com/JhonnyBillM/rust/commit/64aee83e80857dcfa450f0c6e31d5f29c6d577e6) _Part 2 - https://github.com/rust-lang/rust/pull/103792_ r? ``@davidtwco`` Cc ``@compiler-errors``

2023-01-02Auto merge of #84762 - cjgillot:resolve-span-opt, r=petrochenkovbors-50/+56
Encode spans relative to the enclosing item -- enable on nightly Follow-up to #84373 with the flag `-Zincremental-relative-spans` set by default. This PR seeks to remove one of the main shortcomings of incremental: the handling of spans. Changing the contents of a function may require redoing part of the compilation process for another function in another file because of span information is changed. Within one file: all the spans in HIR change, so typechecking had to be re-done. Between files: spans of associated types/consts/functions change, so type-based resolution needs to be re-done (hygiene information is stored in the span). The flag `-Zincremental-relative-spans` encodes local spans relative to the span of an item, stored inside the `source_span` query. Trap: stashed diagnostics are referenced by the "raw" span, so stealing them requires to remove the span's parent. In order to avoid too much traffic in the span interner, span encoding uses the `ctxt_or_tag` field to encode: - the parent when the `SyntaxContext` is 0; - the `SyntaxContext` when the parent is `None`. Even with this, the PR creates a lot of traffic to the Span interner, when a Span has both a LocalDefId parent and a non-root SyntaxContext. They appear in lowering, when we add a parent to all spans, including those which come from macros, and during inlining when we mark inlined spans. The last commit changes how queries of `LocalDefId` manage their cache. I can put this in a separate PR if required. Possible future directions: - validate that all spans are marked in HIR validation; - mark macro-expanded spans relative to the def-site and not the use-site.
