2023-09-11Auto merge of #115308 - chenyukang:yukang-fix-62387-iter-mut, r=davidtwcobors-1/+41

2023-09-11Disentangle `Debug` and `Display` for `Ty`.Nicholas Nethercote-5/+22
The `Debug` impl for `Ty` just calls the `Display` impl for `Ty`. This is surprising and annoying. In particular, it means `Debug` doesn't show as much information as `Debug` for `TyKind` does. And `Debug` is used in some user-facing error messages, which seems bad. This commit changes the `Debug` impl for `Ty` to call the `Debug` impl for `TyKind`. It also does a number of follow-up changes to preserve existing output, many of which involve inserting `with_no_trimmed_paths!` calls. It also adds `Display` impls for `UserType` and `Canonical`. Some tests have changes to expected output: - Those that use the `rustc_abi(debug)` attribute. - Those that use the `EMIT_MIR` annotation. In each case the output is slightly uglier than before. This isn't ideal, but it's pretty weird (particularly for the attribute) that the output is using `Debug` in the first place. They're fairly obscure attributes (I hadn't heard of them) so I'm not worried by this. For `async-is-unwindsafe.stderr`, there is one line that now lacks a full path. This is a consistency improvement, because all the other mentions of `Context` in this test lack a path.
2023-09-07Auto merge of #115602 - oli-obk:lower_intrinsics, r=petrochenkovbors-9/+27
Don't report any errors in `lower_intrinsics`. Intrinsics should have been type checked earlier. This is part of moving all mir-opt diagnostics early enough so that they are reliably emitted even in check builds: https://github.com/rust-lang/rust/issues/49292#issuecomment-1692212095

2023-08-31remove dummy UniverseInfo causes from type checker `fully_perform_op`Rémy Rakic-7/+5
This was backfilling causes for new universes that may have been created by an op, when there was no error info to use for improved diagnostics. We don't need to do that anymore: `other()` is the default when there is no registered universe cause.

2023-08-08Rollup merge of #114566 - fmease:type-alias-laziness-is-crate-specific, ↵Matthias Krüger-1/+1
r=oli-obk Store the laziness of type aliases in their `DefKind` Previously, we would treat paths referring to type aliases as *lazy* type aliases if the current crate had lazy type aliases enabled independently of whether the crate which the alias was defined in had the feature enabled or not. With this PR, the laziness of a type alias depends on the crate it is defined in. This generally makes more sense to me especially if / once lazy type aliases become the default in a new edition and we need to think about *edition interoperability*: Consider the hypothetical case where the dependency crate has an older edition (and thus eager type aliases), it exports a type alias with bounds & a where-clause (which are void but technically valid), the dependent crate has the latest edition (and thus lazy type aliases) and it uses that type alias. Arguably, the bounds should *not* be checked since at any time, the dependency crate should be allowed to change the bounds at will with a *non*-major version bump & without negatively affecting downstream crates. As for the reverse case (dependency: lazy type aliases, dependent: eager type aliases), I guess it rules out anything from slight confusion to mild annoyance from upstream crate authors that would be caused by the compiler ignoring the bounds of their type aliases in downstream crates with older editions. --- This fixes #114468 since before, my assumption that the type alias associated with a given weak projection was lazy (and therefore had its variances computed) did not necessarily hold in cross-crate scenarios (which [I kinda had a hunch about](https://github.com/rust-lang/rust/pull/114253#discussion_r1278608099)) as outlined above. Now it does hold. `@rustbot` label F-lazy_type_alias r? `@oli-obk`

Improve spans for indexing expressions fixes #114388 Indexing is similar to method calls in having an arbitrary left-hand-side and then something on the right, which is the main part of the expression. Method calls already have a span for that right part, but indexing does not. This means that long method chains that use indexing have really bad spans, especially when the indexing panics and that span in coverted into a panic location. This does the same thing as method calls for the AST and HIR, storing an extra span which is then put into the `fn_span` field in THIR. r? compiler-errors

Perform OpaqueCast field projection on HIR, too. fixes #105819 This is necessary for closure captures in 2021 edition, as they capture individual fields, not the full mentioned variables. So it may try to capture a field of an opaque (because the hidden type is known to be something with a field). See https://github.com/rust-lang/rust/pull/99806 for when and why we added OpaqueCast to MIR.
2023-08-03Add `internal_features` lintNilstrieb-0/+1
It lints against features that are inteded to be internal to the compiler and standard library. Implements MCP #596. We allow `internal_features` in the standard library and compiler as those use many features and this _is_ the standard library from the "internal to the compiler and standard library" after all. Marking some features as internal wasn't exactly the most scientific approach, I just marked some mostly obvious features. While there is a categorization in the macro, it's not very well upheld (should probably be fixed in another PR). We always pass `-Ainternal_features` in the testsuite About 400 UI tests and several other tests use internal features. Instead of throwing the attribute on each one, just always allow them. There's nothing wrong with testing internal features^^

Account for macros when suggesting a new let binding Provide a structured suggestion when the expression comes from a macro expansion: ``` error[E0716]: temporary value dropped while borrowed --> $DIR/borrowck-let-suggestion.rs:2:17 | LL | let mut x = vec![1].iter(); | ^^^^^^^ - temporary value is freed at the end of this statement | | | creates a temporary value which is freed while still in use LL | LL | x.use_mut(); | - borrow later used here | = note: this error originates in the macro `vec` (in Nightly builds, run with -Z macro-backtrace for more info) help: consider using a `let` binding to create a longer lived value | LL ~ let binding = vec![1]; LL ~ let mut x = binding.iter(); | ```

Only consider places with the same local in each_borrow_involving_path. This avoids having a busy loop that repeatedly checks for equality of locals.

Double check that hidden types match the expected hidden type Fixes https://github.com/rust-lang/rust/issues/113278 specifically, but I left a TODO for where we should also add some hardening. It feels a bit like papering over the issue, but at least this way we don't get unsoundness, but just surprising errors. Errors will be improved and given spans before this PR lands. r? `@compiler-errors` `@lcnr`

2023-07-24borrowck/errors: fix i18n error in delayed bugDavid Wood-5/+4
During borrowck, the `MultiSpan` from a buffered diagnostic is cloned and used to emit a delayed bug indicating a diagnostic was buffered - when the buffered diagnostic is translated, then the cloned `MultiSpan` may contain labels which can only render with the diagnostic's arguments, but the delayed bug being emitted won't have those arguments. Adds a function which clones `MultiSpan` without also cloning the contained labels, and use this function when creating the buffered diagnostic delayed bug.
