r=compiler-errors
Clean up `OnUnimplementedFormatString::verify`
Lift the always-allowed symbols to a static array and replace a `match iter().find(...)` with `iter().any(...)`

Revert "warn newer available version of the x tool"
Reverts rust-lang/rust#104552
Running the x executable directly created an [issue](https://github.com/rust-lang/rust/issues/106469) here. There are other options for warning a user that a newer version of x exists in the issue's discussion as well.

std tests: use __OsLocalKeyInner from realstd
This is basically the same as https://github.com/rust-lang/rust/pull/100201, but for __OsLocalKeyInner:
Some std tests are failing in Miri on Windows because [this static](https://github.com/rust-lang/rust/blob/a377893da2cd7124e5a18c7116cbb70e16dd5541/library/std/src/sys/windows/thread_local_key.rs#L234-L239) is getting duplicated, and Miri does not handle that properly -- Miri does not support this magic `.CRT$XLB` linker section, but instead just looks up this particular hard-coded static in the standard library. This PR lets the test suite use the std static instead of having its own copy.
Fixes https://github.com/rust-lang/miri/issues/2754

Hide more of long types in E0271
Fix #40186.
|
|
Allow codegen to unsize `dyn*` to `dyn`
`dyn* Trait` is just another type that implements `Trait`, so we should be able to unsize `&dyn* Trait` into `&dyn Trait` perfectly fine, same for `Box` and other unsizeable types.
Fixes #106488
|
|
Prefer non-`[type error]` candidates during selection
Fixes #102130
Fixes #106351
r? types
note: Alternatively we could filter out error where-clauses during param-env construction? But we still need to filter out impls with errors during `match_impl`, I think.

Fix invalid syntax and incomplete suggestion in impl Trait parameter type suggestions for E0311
Fixes #105544
The problems: The suggestion given for E0311 has invalid syntax when the synthetic type parameter is used for Trait type in function declaration:
```rust
fn foo(d: impl Sized) -> impl Sized
```
instead of explicitly specified like the following:
```rust
fn foo<T: Sized>(d: T) -> impl Sized
```
In addition to the syntax error, the suggestions given for E0311 are not complete when multiple elided lifetimes are involved in lifetime bounds, not all involved parameters are given the named lifetime in the suggestions. For the following test case:
```
fn foo(d: impl Sized, p: &mut ()) -> impl Sized + '_ {
(d, p)
}
```
a good suggestion should add the lifetime 'a to both d and p, instead of d only:
```
fn foo<'a>(d: impl Sized + 'a, p: &'a mut ()) -> impl Sized + '_ {
(d, p)
}
```
The Solution: Fix the syntax problem in the suggestions when synthetic type parameter is used, and also add lifetimes for all involved parameters.

Use CI LLVM in `test-various` builder
It was disabled because it needs `lld`, but since #104748 was merged it is no longer needed.
This will speed this test, since it no longer needs to build LLVM.

r=davidtwco
Disable "split dwarf inlining" by default.
This matches clang's behavior and makes split-debuginfo behave as expected (i.e. actually split the debug info).
Fixes #106592

Fixes #106597
r? ```@bjorn3```

Polymorphization cleanup
Split out of #106233
Use a newtype instead of a bitset directly. This makes the code way easier to read and easier to adapt for future changes.

add tests for div_duration_* functions
Per https://github.com/rust-lang/rust/issues/63139#issuecomment-817070719
this adds unit tests for the functions that will hopefully effectively demonstrate that `div_duration` is ready to be stabilized.
|

Improve fluent error messages
These have been really frustrating me while migrating diagnostics.
|
|
Check `impl`'s `where` clauses in `consider_impl_candidate` in experimental solver
Check impl's nested predicates as part of the recursive evaluate in `consider_impl_candidate`.
<sub>Unless, for some reason, these are intentionally **not** checked here -- in which case, I really don't understand where they're being checked...<sub>

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.
