Only emit one error per unsized binding, instead of one per usage Fix #56607.

Decompose singular `matches!` with or-patterns to individual `matches!` statements to enable branchless code output. The following functions were changed: - `is_ascii_alphanumeric` - `is_ascii_hexdigit` - `is_ascii_punctuation` Add codegen tests Co-authored-by: George Bateman <george.bateman16@gmail.com> Co-authored-by: scottmcm <scottmcm@users.noreply.github.com>

Allow target specs to use an LLD flavor, and self-contained linking components This PR allows: - target specs to use an LLD linker-flavor: this is needed to switch `x86_64-unknown-linux-gnu` to using LLD, and is currently not possible because the current flavor json serialization fails to roundtrip on the modern linker-flavors. This can e.g. be seen in rust-lang/rust#115622 (comment) which explains where an `Lld::Yes` is ultimately deserialized into an `Lld::No`. - target specs to declare self-contained linking components: this is needed to switch `x86_64-unknown-linux-gnu` to using `rust-lld` - adds an end-to-end test of a custom target json simulating `x86_64-unknown-linux-gnu` being switched to using `rust-lld` - disables codegen backends from participating because they don't support `-Zgcc-ld=lld` which is the basis of mcp510. r? `@petrochenkov:` if the approach discussed rust-lang/rust#115622 (comment) and on zulip would work for you: basically, see if we can emit only modern linker flavors in the json specs, but accept both old and new flavors while reading them, to fix the roundtrip issue. The backwards compatible `LinkSelfContainedDefault` variants are still serialized and deserialized in `crt-objects-fallback`, while the spec equivalent of e.g. `-Clink-self-contained=+linker` is serialized into a different json object (with future-proofing to incorporate `crt-objects-fallback` in the future). --- I've been test-driving this in rust-lang/rust#113382 to test actually switching `x86_64-unknown-linux-gnu` to `rust-lld` (and fix what needs to be fixed in CI, bootstrap, etc), and it seems to work fine.

ZeroSized constants can be represented as `mir::Const::Val` even if their layout is not yet known. In those cases, CrateItem::body() was crashing when trying to convert a `ConstValue::ZeroSized` into its stable counterpart `ConstantKind::Allocated`. Instead, we now map `ConstValue::ZeroSized` into a new variant: `ConstantKind::ZeroSized`.

Refactor some `char`, `u8` ASCII functions to be branchless Extract conditions in singular `matches!` with or-patterns to individual `matches!` statements which enables branchless code output. The following functions were changed: - `is_ascii_alphanumeric` - `is_ascii_hexdigit` - `is_ascii_punctuation` Added codegen tests --- Continued from rust-lang/rust#103024. Based on the comment from `@scottmcm` rust-lang/rust#103024 (review). The unmodified `is_ascii_*` functions didn't seem to benefit from extracting the conditions. I've never written a codegen test before, but I tried to check that no branches were emitted.

The demangler was only needed by coverage tests, but those tests were migrated into their own custom test mode in #112300. This avoids having to build the demangler just for run-make tests. It will still be built as needed by run-coverage tests or for other purposes.

This avoids useless rebuilds of the demangler when modifying the compiler.

This hopefully fixes the CI run after integration of this target.

…i-obk Stash and cancel cycle errors for auto trait leakage in opaques We don't need to emit a traditional cycle error when we have a selection error that explains what's going on but in more detail. We may want to augment this error to actually point out the cycle, now that the cycle error is not being emitted. We could do that by storing the set of opaques that was in the `CyclePlaceholder` that gets returned from `type_of_opaque`. r? `@oli-obk` cc `@estebank` #117235

Create a new ConstantKind variant (ZeroSized) for StableMIR ZeroSized constants can be represented as `mir::Const::Val` even if their layout is not yet known. In those cases, CrateItem::body() was crashing when trying to convert a `ConstValue::ZeroSized` into its stable counterpart `ConstantKind::Allocated`. Instead, we now map `ConstValue::ZeroSized` into a new variant: `ConstantKind::ZeroSized`. **Note:** I didn't add any new test here since we already have covering tests in our project repository which I manually confirmed that will fix the issue.

replace transmute by raw pointer cast Now that rust-lang/rust#113257 is fixed we can finally do this. :)

Correctly handle nested or-patterns in exhaustiveness I had assumed nested or-patterns were flattened, and they mostly are but not always. Fixes rust-lang/rust#117378

…9, r=compiler-errors Poison check_well_formed if method receivers are invalid to prevent typeck from running on it fixes #117379 Though if some code invokes typeck without having first invoked `check_well_formed` then we'll encounter this ICE again. This can happen in const and const fn bodies if they are evaluated due to other `check_well_formed` checks or similar

…er-errors,Nilstrieb Improve some diagnostics around `?Trait` bounds * uses better spans * clarifies a message that was only talking about generic params, but applies to `dyn ?Trait` and `impl ?Trait` as well

Don't normalize to an un-revealed opaque when we hit the recursion limit Currently, we will normalize `Opaque := Option<&Opaque>` to something like `Option<&Option<&Option<&...Opaque>>>`, hitting a limit and bottoming out in an unnormalized opaque after the recursion limit gets hit. Unfortunately, during `layout_of`, we'll simply recurse and try again if the type normalizes to something different than the type: https://github.com/rust-lang/rust/blob/e6e931dda5fffbae0fd87c5b1af753cc95556880/compiler/rustc_ty_utils/src/layout.rs#L58-L60 That means then we'll try to normalize `Option<&Option<&Option<&...Opaque>>>` again, substituting `Opaque` into itself even deeper. Eventually this will get to the point that we're just stack-overflowing on a really deep type before even hitting an opaque again. To fix this, we just bottom out into `ty::Error` instead of the unrevealed opaque type. Fixes #117412 r? `@oli-obk`

When an associated type with GATs isn't specified in a `dyn Trait`, emit an object safety error instead of only complaining about the missing associated type, as it will lead the user down a path of three different errors before letting them know that what they were trying to do is impossible to begin with. Fix #103155.

…iasko Enable cross-crate-inlining when MIR inlining is enabled This would make rust-lang/rust#117355 generally less obscure, and also seems like a good idea, even if for some reason someone wants MIR opts but no codegen opts.
