Stop mentioning internal lang items in no_std binary errors

2024-01-10T20:18:54+00:00

When writing a no_std binary, you'll be greeted with nonsensical errors mentioning lang items like eh_personality and start. That's pretty bad because it makes you think that you need to define them somewhere! But oh no, now you're getting the `internal_features` lint telling you that you shouldn't use them! But you need a no_std binary! What now? No problem! Writing a no_std binary is super easy. Just use panic=abort and supply your own platform specific entrypoint symbol (like `main`) and you're good to go. Would be nice if the compiler told you that, right? This makes it so that it does do that.

Rename some `Diagnostic` setters.

2024-01-03T08:40:20+00:00

`Diagnostic` has 40 methods that return `&mut Self` and could be considered setters. Four of them have a `set_` prefix. This doesn't seem necessary for a type that implements the builder pattern. This commit removes the `set_` prefixes on those four methods.

Add `level` arg to `into_diagnostic`.

2023-12-18T22:19:25+00:00

And make all hand-written `IntoDiagnostic` impls generic, by using `DiagnosticBuilder::new(dcx, level, ...)` instead of e.g. `dcx.struct_err(...)`. This means the `create_*` functions are the source of the error level. This change will let us remove `struct_diagnostic`. Note: `#[rustc_lint_diagnostics]` is added to `DiagnosticBuilder::new`, it's necessary to pass diagnostics tests now that it's used in `into_diagnostic` functions.

Rename many `DiagCtxt` arguments.

2023-12-18T05:06:22+00:00

Rename `Handler` as `DiagCtxt`.

2023-12-18T05:06:19+00:00

Remove `UnknownPartitionStrategy` error.

2023-10-18T03:42:58+00:00

This became unused in #112053, when `-Zcgu-partitioning-strategy` was removed.

Emit error instead of ICE when optimized MIR is missing

2023-08-30T18:43:31+00:00

Closes 51388.

errors: generate typed identifiers in each crate

2023-02-22T09:15:53+00:00

Instead of loading the Fluent resources for every crate in `rustc_error_messages`, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the `rustc_driver` crate and provided to the diagnostic emitter. Signed-off-by: David Wood
