Darwin's `read`/`write` syscalls emit `EINVAL` only when `nbyte > INT_MAX`.
The case `nbyte == INT_MAX` is valid, so the subtraction can be removed.

Apparently they are no longer split 1 LHS + rest RHS

Add !clippy_test_deps/Cargo.lock and clippy_lints_internal/target

This check is relatively cheap, and is a quick way to root out breaking
check flow of `bootstrap` itself.
|
|
I missed this during review. We cannot declare a `tests` module within
`shared_helpers.rs` itself, as shim binaries that tries to include the
`shared_helpers` module through `#[path = ".."]` attributes would fail
to find it, breaking `./x check bootstrap`.
This reverts commit `40c2ca96411caaeab1563ff9041879f742d1d71b`.

Remove usage of Any, reduce visibility of fields and remove unused

rustc_public: Remove movability from `RigidTy/AggregateKind::Coroutine`
Part of rust-lang/rust#119174 .
I think we should be good now to sync this change in rustc_public.
|
|
Remove dead code and extend test coverage and diagnostics around it
I was staring a bit at the `dont_niche_optimize_enum` variable and figured out that part of it is dead code (at least today it is). I changed the diagnostic and test around the code that makes that part dead code, so everything that makes removing that code sound is visible in this PR

resolve: Remove `Scope::CrateRoot`
Use `Scope::Module` with the crate root module inside instead, which should be identical.
This is a simplification by itself, but it will be even larger simplification if something like https://github.com/rust-lang/rust/pull/144131 is implemented, because `Scope::CrateRoot` is also a module with two actual scopes in it (for globs and non-globs).
I also did some renamings for consistency:
- `ScopeSet::AbsolutePath` -> `ScopeSet::ModuleAndExternPrelude`
- `ModuleOrUniformRoot::CrateRootAndExternPrelude` -> `ModuleOrUniformRoot::ModuleAndExternPrelude`
- `is_absolute_path` -> `module_and_extern_prelude`

UI test suite clarity changes: Rename `tests/ui/SUMMARY.md` and update rustc dev guide on `error-pattern`
To match convention, rename `tests/ui/SUMMARY.md` to `tests/ui/README.md`.
Also, remove misleading lines in the rustc development guide about `error-pattern` being "not recommended", when it really is just a last resort which *should* be used in the niche situations where it is useful.

Hint that choose_pivot returns index in bounds
Instead of using `unsafe` in multiple places, one `hint::assert_unchecked` allows use of safe code instead.
Part of #rust-lang/rust#144326
|
|
Don't emit two `assume`s in transmutes when one is a subset of the other
For example, transmuting between `bool` and `Ordering` doesn't need two `assume`s because one range is a superset of the other.
Multiple are still used for things like `char` <-> `NonZero<u32>`, which overlap but where neither fully contains the other.

Tweak output for non-`Clone` values moved into closures
When we encounter a non-`Clone` value being moved into a closure, try to find the corresponding type of the binding being moved, if it is a `let`-binding or a function parameter. If any of those cases, we point at them with the note explaining that the type is not `Copy`, instead of giving that label to the place where it is captured. When it is a `let`-binding with no explicit type, we point at the initializer (if it fits in a single line).
```

Test fixes for Arm64EC Windows
* `tests/ui/cfg/conditional-compile-arch.rs` needs an Arm64EC case.
* `tests/ui/runtime/backtrace-debuginfo.rs` should skip Arm64EC as it suffers from the same truncated backtraces as Arm64 Windows.
* `tests/ui/linkage-attr/incompatible-flavor.rs` is a general issue: it assumes that the Rust compiler is always built with the x86 target enabled in the backend, but I only enabled AArch64 when building locally to speed up the LLVM compilation.

r=davidtwco
tests: Don't check for self-printed output in std-backtrace.rs test
The `Display` implementation for `Backtrace` used to print
stack backtrace:
but that print was since removed. See https://github.com/rust-lang/backtrace-rs/pull/286 and https://github.com/rust-lang/rust/pull/69042. To make the existing test pass, the print was added to the test instead. But it doesn't make sense to check for something that the test itself does since that will not detect any regressions in the implementation of `Backtrace`.
What the test _should_ check is that "stack backtrace:" is _not_ printed in `Display` of `Backtrace`. So do that instead.
This is one small steps towards resolving https://github.com/rust-lang/rust/issues/71706. The next steps after this step involves extending and hardening that test further.
