The implementation seems trivial, so I can review and approve, but if you want someone from the const eval group to do that, feel free to reassign.
This also needs a rebase and a fix for the error index.

make type-check-4 asm tests about non-const expressions
These tests recently got changed in rust-lang#129759. I asked the PR author to make the tests read from a static mut
(rather than just making them "pass"), but I now think that was a mistake: previously the tests failed because the const was not a valid const expression, after the PR they failed because the const failed to evaluate.
So this PR restores the tests to "fail because the const is not a valid const expression". That can be done in a target-independent way so I unified the x86 and aarch64 tests into one.
Cc @oli-obk
as the original author of these tests -- not sure if you still remember what they were intended to test.

Cargo
- [Introduced a new
CARGO_MANIFEST_PATH
environment variable, similar toCARGO_MANIFEST_DIR
but pointing directly to the manifest file.] (rust-lang/cargo#14404) - [Added
package.autolib
to the manifest, allowing[lib]
auto-discovery to be disabled.] (rust-lang/cargo#14591) - [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600)
- [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599)
Rustdoc
- [The sidebar / hamburger menu table of contents now includes the
# headers
from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.
Compatibility Notes
[Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784)
[Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer
[Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073)
Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass
MACOSX_DEPLOYMENT_TARGET

[RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)
We want to change this behaviour such that, when
rust-src
source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a--remap-path-prefix
that causes this local path to be remapped in the usual way.#129687 implements this behaviour, when
rust-src
is present at compile time,rustc
replaces/rustc/$hash
with a real path into the localrust-src
component with best effort. To sanitize this, users must explicitly supply--remap-path-prefix=<path to rust-src>=foo
or not have therust-src
component installed.The allow-by-default
missing_docs
lint used to disable itself when invoked throughrustc --test

emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows#[expect(missing_docs)]

Release Notes
rust-lang/rust (rust)
v1.83.0
==========================
Language
- Stabilize
&mut
,*mut
,&Cell
, and*const Cell
in const. - Allow creating references to statics in
const
initializers. - Implement raw lifetimes and labels (
'r#ident
). - Define behavior when atomic and non-atomic reads race.
- Non-exhaustive structs may now be empty.
- Disallow implicit coercions from places of type
!
const extern
functions can now be defined for other calling conventions.- Stabilize
expr_2021
macro fragment specifier in all editions. - The
non_local_definitions
lint now fires on less code and warns by default.
Compiler
- Deprecate unsound
-Csoft-float
flag. - Add many new tier 3 targets:
Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.
Libraries
- Implement
PartialEq
forExitCode
. - Document that
catch_unwind
can deal with foreign exceptions without UB, although the exact behavior is unspecified. - Implement
Default
forHashMap
/HashSet
iterators that don't already have it. - Bump Unicode to version 16.0.0.
- Change documentation of
ptr::add
/sub
to not claim equivalence withoffset
.

Cargo
- Introduced a new
CARGO_MANIFEST_PATH
environment variable, similar toCARGO_MANIFEST_DIR
but pointing directly to the manifest file. - Added
package.autolib
to the manifest, allowing[lib]
auto-discovery to be disabled. - Declare support level for each crate in Cargo's Charter / crate docs.
- Declare new Intentional Artifacts as 'small' changes.
Rustdoc
- The sidebar / hamburger menu table of contents now includes the
# headers
from the main item's doc comment. This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.
Compatibility Notes
Warn against function pointers using unsupported ABI strings.
Check well-formedness of the source type's signature in fn pointer casts. This partly closes a soundness hole that comes when casting a function item to function pointer
Use equality instead of subtyping when resolving type dependent paths.
Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass
MACOSX_DEPLOYMENT_TARGET

Cargo
- [Introduced a new
CARGO_MANIFEST_PATH
environment variable, similar toCARGO_MANIFEST_DIR
but pointing directly to the manifest file.] (rust-lang/cargo#14404) - [Added
package.autolib
to the manifest, allowing[lib]
auto-discovery to be disabled.] (rust-lang/cargo#14591) - [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600)
- [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599)
Rustdoc
- [The sidebar / hamburger menu table of contents now includes the
# headers
from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.
Compatibility Notes
[Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784)
[Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer
[Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073)
Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass
MACOSX_DEPLOYMENT_TARGET
or fix your#[link]
attributes to point to the correct frameworks. See <rust-lang/rust#129369>.[Rust will now correctly raise an error for
repr(Rust)
written on non-struct
/enum
/union
items, since it previous did not have any effect.] (rust-lang/rust#129422)The future incompatibility lint
deprecated_cfg_attr_crate_type_name
[has been made into a hard error] (rust-lang/rust#129670). It was used to deny usage of#![crate_type]
and#![crate_name]
attributes in#![cfg_attr]
, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use--crate-type
instead of#![cfg_attr(..., crate_type = "...")]
and--crate-name
instead of#![cfg_attr(..., crate_name = "...")]
when runningrustc
/cargo rustc
on the command line. Use of those two attributes outside of#![cfg_attr]
continue to be fully supported.Until now, paths into the sysroot were always prefixed with
/rustc/$hash

[RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)
We want to change this behaviour such that, when
rust-src
source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a--remap-path-prefix
that causes this local path to be remapped in the usual way.#129687 implements this behaviour, when
rust-src
is present at compile time,rustc
replaces/rustc/$hash
with a real path into the localrust-src
component with best effort. To sanitize this, users must explicitly supply--remap-path-prefix=<path to rust-src>=foo
or not have therust-src
component installed.The allow-by-default
missing_docs
lint used to disable itself when invoked throughrustc --test
/cargo test
, resulting in#[expect(missing_docs)]
emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows#[expect(missing_docs)]
to be fulfilled in all scenarios, but will also report newmissing_docs
diagnostics for publicly reachable#[cfg(test)]
items, [integration test] (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.[The
