by using an opaque type obligation to bubble up comparisons between opaque types and other types
Also uses proper obligation causes so that the body id works, because out of some reason nll uses body ids for logic instead of just diagnostics.

remove `TyS::same_type`
This function ignored regions and constants in adts, but didn't do so for references or any other types. cc https://github.com/rust-lang/rust/pull/93148#discussion_r791408057

This seemed quite weird

rustc_errors: only box the `diagnostic` field in `DiagnosticBuilder`.
I happened to need to do the first change (replacing `allow_suggestions` with equivalent functionality on `Diagnostic` itself) as part of a larger change, and noticed that there's only two fields left in `DiagnosticBuilderInner`.
So with this PR, instead of a single pointer, `DiagnosticBuilder` is two pointers, which should work just as well for passing *it* by value (and may even work better wrt some operations, though probably not by much).
But anything that was already taking advantage of `DiagnosticBuilder` being a single pointer, and wrapping it further (e.g. `Result<T, DiagnosticBuilder>` w/ non-ZST `T`), ~~will probably see a slowdown~~, so I want to do a perf run before even trying to propose this.

Create `core::fmt::ArgumentV1` with generics instead of fn pointer
Split from (and prerequisite of) #90488, as this seems to have perf implication.

Store a `Symbol` instead of an `Ident` in `AssocItem`
This is the same idea as #92533, but for `AssocItem` instead
of `VariantDef`/`FieldDef`.
With this change, we no longer have any uses of

Override rustc version in ui and mir-opt tests to get stable hashes
Building a dozen separate regexps for each test in compiletest consumes significant amounts of CPU cycles.

Emit simpler code from format_args
I made this PR so that `cargo expand` dumps a less overwhelming amount of formatting-related code.

`println!("rust")` **Before:**
```rust
{
::std::io::_print(::core::fmt::Arguments::new_v1(&["rust\n"],
&match () {
_args => [],

};
```
**After:**
```rust
{ ::std::io::_print(::core::fmt::Arguments::new_v1(&["rust\n"], &[])); };
```
`println!("{}", x)` **Before:**
```rust

&match (&x,) {
_args => [::core::fmt::ArgumentV1::new(
_args.0,

Building a dozen separate regexps for each test in compiletest consumes significant amounts of CPU cycles.
Using `RUSTC_FORCE_INCR_COMP_ARTIFACT_HEADER` stabilizes hashes calcuated for the individual tests so
no test-dependent normalization is needed. Hashes for the standard library still change so some
normalizations are still needed.

Add manifest docs fallback.
This adds a fallback so that the rustup manifest will contain the rust-docs component for all hosts. There is a mapping so that the docs that get downloaded are roughly close to the actual host. There inevitably will be things that don't match. Ideally the standard library docs would be the same for every platform (`cfg(doc)` goes a long way towards this), but there are still lots of minor differences.
Closes #69525

mangling_v0: Skip extern blocks during mangling
There's no need to include the dummy `Nt` into the symbol name, items in extern blocks belong to their parent modules for all purposes except for inheriting the ABI and attributes.
Follow up to https://github.com/rust-lang/rust/pull/92032
(There's also a drive-by fix to the `rust-demangler` tool's tests, which don't run on CI, I initially attempted using them for testing this PR.)

Out of cycle Clippy update
I want to do an out-of-cycle sync for rust-lang/rust-clippy#8295, and possibly backport this to stable together with https://github.com/rust-lang/rust/issues/92938. If this doesn't get backported to stable, then I at least want to backport it to beta.

Also prevent ICE when adding a const in associated const equality.
|
|
Removes uses of ty() where a method is implemented on TypeFoldable, and also directly formats
a Term.
|
|
Replace use of `ty()` on term and use it in more places. This will allow more flexibility in the
future, but slightly worried it allows items which are consts which only accept types.
|
|
|
|
ProjectionPredicate should be able to handle both associated types and consts so this adds the
first step of that. It mainly just pipes types all the way down, not entirely sure how to handle
consts, but hopefully that'll come with time.

The version was removed in https://github.com/rust-lang/rust/pull/77145/

Instead of having a separate enum variant for types and consts have one but have either a const
or type.

Replace `NestedVisitorMap` with generic `NestedFilter`
This is an attempt to make the `intravisit::Visitor` API simpler and "more const" with regard to nested visiting.
With this change, `intravisit::Visitor` does not visit nested things by default, unless you specify `type NestedFilter = nested_filter::OnlyBodies` (or `All`). `nested_visit_map` returns `Self::Map` instead of `NestedVisitorMap<Self::Map>`. It panics by default (unreachable if `type NestedFilter` is omitted).
One somewhat trixty thing here is that `nested_filter::{OnlyBodies, All}` live in `rustc_middle` so that they may have `type Map = map::Map` and so that `impl Visitor`s never need to specify `type Map` - it has a default of `Self::NestedFilter::Map`.

Remove deprecated LLVM-style inline assembly
The `llvm_asm!` was deprecated back in #87590 1.56.0, with intention to remove
it once `asm!` was stabilized, which already happened in #91728 1.59.0. Now it
is time to remove `llvm_asm!` to avoid continued maintenance cost.
Closes #70173.
Closes #92794.
Closes #87612.
Closes #82065.
