832751fe1d Also erase substs for new infcx in pin move error
The code originally correctly erased the regions of the type it passed
to the newly created infcx. But after the `fn_sig` query was made to
return an `EarlyBinder<T>`, some substs that were around were
substituted there without erasing their regions. They were then passed
into the newly cerated infcx, which caused the ICE.

Remove HirId -> LocalDefId map from HIR.

Having this map in HIR prevents the creating of new definitions after HIR has been built.
Thankfully, we do not need it.

This PR adds a debug assertion that the parts of a single substitution cannot overlap, fixes a overlapping substitution from the testsuite, and fixes https://github.com/rust-lang/rust/issues/106870.

Note that a single suggestion can still have multiple overlapping substitutions / possible edits, we just don't suggest overlapping replacements in a single edit anymore.

I've also included a fix for an unrelated bug where rustfix for `explicit_outlives_requirements` would produce multiple trailing commas for a where clause.

Rollup merge of #107373 - michaelwoerister:dont-merge-vtables-when-debuginfo, r=WaffleLapkin
Don't merge vtables when full debuginfo is enabled.

This PR makes the compiler not emit the `unnamed_addr` attribute for vtables when full debuginfo is enabled, so that they don't get merged even if they have the same contents. This allows debuggers to more reliably map from a dyn pointer to the self-type of a trait object by looking at the vtable's debuginfo.

The PR only changes the behavior of the LLVM backend as other backends don't emit vtable debuginfo (as far as I can tell).

The performance impact of this change should be small as [measured](https://github.com/rust-lang/rust/pull/103514#issuecomment-1290833854) in a previous PR.

Rollup merge of #107339 - aliemjay:covariant, r=lcnr
internally change regions to be covariant

Surprisingly, we consider the reference type `&'a T` to be contravaraint in its lifetime parameter. This is confusing and conflicts with the documentation we have in the reference, rustnomicon, and rustc-dev-guide. This also arguably not the correct use of terminology since we can use `&'static u8` in a place where `&' a u8` is expected, this implies that `&'static u8 <: &' a u8` and consequently `'static <: ' a`, hence covariance.

Because of this, when relating two types, we used to switch the argument positions in a confusing way:
`Subtype(&'a u8 <: &'b u8) => Subtype('b <: 'a) => Outlives('a: 'b) => RegionSubRegion('b <= 'a)`

The reason for the current behavior is probably that we wanted `Subtype('b <: 'a)` and `RegionSubRegion('b <= 'a)` to be equivalent, but I don' t think this is a good reason since these relations are sufficiently different in that the first is a relation in the subtyping lattice and is intrinsic to the type-systems, while the the second relation is an implementation detail of regionck.

This PR changes this behavior to use covariance, so..
`Subtype(&'a u8 <: &'b u8) => Subtype('a <: 'b) => Outlives('a: 'b) => RegionSubRegion('b <= 'a) `

Resolves #103676

Rollup merge of #107190 - fmease:fix-81698, r=compiler-errors
Recover from more const arguments that are not wrapped in curly braces

Recover from some array, borrow, tuple & arithmetic expressions in const argument positions that lack curly braces and provide a suggestion to fix the issue continuing where #92884 left off. Examples of such expressions: `[]`, `[0]`, `[1, 2]`, `[0; 0xff]`, `&9`, `("", 0)` and `(1 + 2) * 3` (we previously did not recover from them).

I am not entirely happy with my current solution because the code that recovers from `[0]` (coinciding with a malformed slice type) and `[0; 0]` (coinciding with a malformed array type) is quite fragile as the aforementioned snippets are actually successfully parsed as types by `parse_ty` since it itself already recovers from them (returning `[⟨error⟩]` and `[⟨error⟩; 0]` respectively) meaning I have to manually look for `TyKind::Err`s and construct a separate diagnostic for the suggestion to attach to (thereby emitting two diagnostics in total).

Fixes #81698.

6cd6bad51f Auto merge of #101692 - cjgillot:generator-lazy-witness, r=oli-obk
Compute generator saved locals on MIR

Generators are currently type-checked by introducing a `witness` type variable, which is unified with a `GeneratorWitness(captured types)` whose purpose is to ensure that the auto traits correctly migrate from the captured types to the `witness` type.  This requires computing the captured types on HIR during type-checking, only to re-do it on MIR later.

This PR proposes to drop the HIR-based computation, and only keep the MIR one.  This is done in 3 steps.
1. During type-checking, the `witness` type variable is never unified.  This allows to stall all the obligations that depend on it until the end of type-checking.  Then, the stalled obligations are marked as successful, and saved into the typeck results for later verification.
2. At type-checking writeback, `witness` is replaced by `GeneratorWitnessMIR(def_id, substs)`.  From this point on, all trait selection involving `GeneratorWitnessMIR` will fetch the MIR-computed locals, similar to what opaque types do.  There is no lifetime to be preserved here: we consider all the lifetimes appearing in this witness type to be higher-ranked.
3. After borrowck, the stashed obligations are verified against the actually computed types, in the `check_generator_obligations` query.  If any obligation was wrongly marked as fulfilled in step 1, it should be reported here.

There are still many issues:
- ~I am not too happy having to filter out some locals from the checked bounds, I think this is MIR building that introduces raw pointers polluting the analysis;~ solved by a check specific to static variables.
- the diagnostics for captured types don't show where they are used/dropped;
- I do not attempt to support chalk.

rustdoc: Collect "rustdoc-reachable" items during early doc link resolution

This pass only needs to know about visibilities, attributes and reexports, so it can be run early, similarly to `compute_effective_visibilities` in rustc.
Results of this pass can be used to prune the list of extern impls early thus improving performance of https://github.com/rust-lang/rust/pull/94857.

rustc_metadata: Fix `encode_attrs`

This function didn't do what the authors intended it to do.

- Due to `move` in the closure `is_public` wasn't captured by mutalbe reference and wasn't used as a cache.
- Due to iterator cloning all the `should_encode_attr` logic run for the second time to calculate `may_have_doc_links`

This PR fixes these issues, and calculates all the needed attribute flags in one go.

(Noticed while implementing https://github.com/rust-lang/rust/pull/107136.)

Rollup merge of #106856 - vadorovsky:fix-atomic-annotations, r=joshtriplett
core: Support variety of atomic widths in width-agnostic functions

Before this change, the following functions and macros were annotated with `#[cfg(target_has_atomic = "8")]` or
`#[cfg(target_has_atomic_load_store = "8")]`:

* `atomic_int`
* `strongest_failure_ordering`
* `atomic_swap`
* `atomic_add`
* `atomic_sub`
* `atomic_compare_exchange`
* `atomic_compare_exchange_weak`
* `atomic_and`
* `atomic_nand`
* `atomic_or`
* `atomic_xor`
* `atomic_max`
* `atomic_min`
* `atomic_umax`
* `atomic_umin`

However, none of those functions and macros actually depend on 8-bit width and they are needed for all atomic widths (16-bit, 32-bit, 64-bit etc.). Some targets might not support 8-bit atomics (i.e. BPF, if we would enable atomic CAS for it).

This change fixes that by removing the `"8"` argument from annotations, which results in accepting the whole variety of widths.

Fixes #106845
Fixes #106795

Move format_args!() into AST (and expand it during AST lowering)

Implements https://github.com/rust-lang/compiler-team/issues/541

This moves FormatArgs from rustc_builtin_macros to rustc_ast_lowering. For now, the end result is the same. But this allows for future changes to do smarter things with format_args!(). It also allows Clippy to directly access the ast::FormatArgs, making things a lot easier.

This change turns the format args types into lang items. The builtin macro used to refer to them by their path. After this change, the path is no longer relevant, making it easier to make changes in `core`.

This updates clippy to use the new language items, but this doesn't yet make clippy use the ast::FormatArgs structure that's now available. That should be done after this is merged.

ICE in new solver if we see an inference variable

By construction, we do not expect to see any `ty::Infer(ty::TyVar(_))` inference types in the solver (we treat this as ambiguous, since we need to be able to structurally resolve the self type at least one layer to assemble candidates for it). Additionally, since we're doing no freshening, we also don't expect to see any fresh vars of any kind in the solver.

Let's make that an ICE so we can catch any mistakes.

When #107282 lands, we should also ICE there too if we see a non-int/float infer.

There are still various places (marked with FIXMEs) that assume all pointers
have the same size and alignment. Fixing this requires parsing non-default
address spaces in the data layout string (and various other changes),
which will be done in a followup.
(That is, if it's actually worth it to support multiple different pointer sizes.
There is a lot of code that would be affected by that.)

Fix escaping inference var ICE in `point_at_expr_source_of_inferred_type`

Fixes #107158

`point_at_expr_source_of_inferred_type` uses `lookup_probe` to adjust the self type of a method receiver -- but that method returns inference variables from inside a probe. That means that the ty vars are no longer valid, so we can't use any infcx methods on them.

Also, pass some extra span info to hack a quick solution to bad labels, resulting in this diagnostic improvement:

```rust
fn example2() {
    let mut x = vec![1];
    x.push("");
}
```

```diff
  error[E0308]: mismatched types
   --> src/main.rs:5:12
    |
  5 |     x.push("");
    |       ---- ^^

Add hint for missing lifetime bound on trait object when type alias is used

Fix issue #103582.

The problem: When a type alias is used to specify the return type of the method in a trait impl, the suggestion for fixing the problem of "missing lifetime bound on trait object" of the trait impl will not be created. The issue caused by the code which searches for the return trait objects when constructing the hint suggestion is not able to find the trait objects since they are specified in the type alias path instead of the return path of the trait impl.

The solution: Trace the trait objects in the type alias path and provide them along with the alias span to generate the suggestion in case the type alias is used in return type of the method in the trait impl.

use `LocalDefId` instead of `HirId` in trait resolution to simplify the obligation clause resolution

This commit introduces a refactoring suggested by `@lcnr` to simplify the obligation clause resolution.

This is just the first PR that introduces a type of refactoring, but others PRs will follow this to introduce name changing to change from the variable name from `body_id` to something else.

This function didn't do what the authors intended it to do.

- Due to `move` in the closure `is_public` wasn't captured by mutalbe reference and wasn't used as a cache.
- Due to iterator cloning all the `should_encode_attr` logic run for the second time to calculate `may_have_doc_links`

This PR fixes these issues, and calculates all the needed attribute flags in one go.

1cd7dbfbf8 Add target_has_atomic* symbols if any atomic width is supported
Atomic operations for different widths (8-bit, 16-bit, 32-bit etc.) are
guarded by `target_has_atomic = "value"` symbol (i.e. `target_has_atomic
= "8"`) (and the other derivatives), but before this change, there was
no width-agnostic symbol indicating a general availability of atomic
operations.

This change introduces:

* `target_has_atomic_load_store` symbol when atomics for any integer
  width are supported by the target.
* `target_has_atomic` symbol when also CAS is supported.

Fixes #106845

BPF: Disable atomic CAS

Enabling CAS for BPF targets (https://github.com/rust-lang/rust/pull/105708) breaks the build of core library.
The failure occurs both when building rustc for BPF targets and when
building crates for BPF targets with the current nightly.

The LLVM BPF backend does not correctly lower all `atomicrmw` operations
and crashes for unsupported ones.

Before we can enable CAS for BPF in Rust, we need to fix the LLVM BPF
backend first.

Rollup merge of #107102 - compiler-errors:new-solver-new-candidats-4, r=lcnr
Implement some more predicates in the new solver

Implement a few more goals. The subtype goal specifically is important, since it's required for this code to compile:

```
fn main() {
  let mut x = vec![];
  x.push(1i32);
}
```

(I think we emit a subtype goal here because of coercion).

Drive-by: Also implements `--compare-mode=next-solver` -- I've been using this locally a lot to find out what works and what doesn't. I'm also happy to split this out into another PR.

Rollup merge of #106113 - krasimirgg:llvm-16-ext-tyid, r=nikic
llvm-wrapper: adapt for LLVM API change

No functional changes intended.

The LLVM commit e6b02214c6 added `TargetExtTyID` to the `TypeID` enum. This adapts `RustWrapper` accordingly.

415c14129b rustc_metadata: Encode doc(hidden) flag to metadata
To retrieve these flags rustdoc currently has to mass decode full attributes for items in the whole crate tree, so it's better to pre-compute it in advance.

This is especially for short-term performance of https://github.com/rust-lang/rust/pull/107054 because resolver cannot use memoization of query results yet.
