Since [1], this will come automatically from `rustc-std-workspace-core`
and the crates.io dependency should no longer be specified.
[1]: https://github.com/rust-lang/rust/pull/141993
We move the vectorcall ABI tests into their own file which is now
only run on x86-64, while replacing them with rust-cold ABI tests
so that aarch64 hosts continue to test an unstable ABI.
A better solution might be cross-compiling or something but
I really don't have time for that right now.
Enable Non-determinism of float operations in Miri and change std tests
Links to [#4208](https://github.com/rust-lang/miri/issues/4208) and [#3555](https://github.com/rust-lang/miri/issues/3555) in Miri.
Non-determinism of floating point operations was disabled in rust-lang/rust#137594 because it breaks the tests and doc-tests in core/coretests and std. This PR enables some of them.
This pr includes the following changes:
- Enables the float non-determinism but with a lower relative error of 4ULP instead of 16ULP
- These operations now have a fixed output based on the C23 standard, except the pow operations, this is tracked in [#4286](https://github.com/rust-lang/miri/issues/4286#issue-3010677983)
- Changes tests that made incorrect assumptions about the operations, not to make that assumption anymore (from `assert_eq!` to `assert_approx_eq!`.
- Changed the doctests of the stdlib of these operations to compare against fixed constants instead of `f*::EPSILON`, which now succeed with Miri and `-Zmiri-many-seeds`
- Added a constant `APPROX_DELTA` in `std/tests/floats/f32.rs` which is used for approximation tests, but with a different value when run in Miri. This is to make these tests succeed.
- Added tests in the float tests of Miri to test the C23 behaviour.
Fixes https://github.com/rust-lang/miri/issues/4208
This takes the current behavior of `file!` and documents it so it is
safe to make assumptions about.
For example, Cargo could provide a `CARGO_RUSTC_CURRENT_DIR` as a base
path for `file!`.
Example use cases
- Being able to look up test assets relative to the current file
([example](b9026bf654/tests/testsuite/cargo_add/add_basic/mod.rs (L34)))
- Inline snapshotting libraries being able to update Rust source code
([example](b9026bf654/tests/testsuite/alt_registry.rs (L36-L45)))
T-libs-api discussed two solutions
- `file_absolute!`:
- Has less meaning in other build tools like buck2
- Bakes in the assumption that a full path is available (e.g. with
trim-paths)
- Specifying `file!`s behavior (this PR):
- Leaves it to the user to deal with trim-paths
- Even though `file!` is currently unspecified, changing it would
likely have too large of an impact on the ecosystem at this time.
A future possibility is that rustc could have a flag that controls
modifies the base path used for `file!`.
That seems purely additive with specifying the behavior and we do not
want to block on it.
It would also likely be too disruptive for Cargo users (as mentioned).
However, we tried to keep this in mind when specifying the behavior.
It's purely internal, and not intended to be a public API, even on
nightly. This stops it showing up and being misleading in rustdoc
search.
It also mirrors the (also internal) `core::slice::sort` module.
Stabilize `sha512`, `sm3` and `sm4` for x86
This PR stabilizes the feature flag `sha512_sm_x86` (tracking issue rust-lang/rust#126624).
# Public API
The 3 `x86` target features `sha512`, `sm3` and `sm4`, and the associated intrinsics in stdarch.
These target features are very specialized, and are only used to signal the presence of the corresponding CPU instruction. They don't have any nontrivial interaction with the ABI (contrary to something like AVX), and serve the only purpose of enabling 10 stdarch intrinsics, all of which have been implemented and propagated to rustc via a stdarch submodule update.
Also, these were added in LLVM17, and as the minimum LLVM required for rustc is LLVM19, we are safe in that front too!
# Associated PRs
- rust-lang/rust#126704
- rust-lang/stdarch#1592
- rust-lang/stdarch#1790
- rust-lang/rust#140389 (stdarch submodule update)
- rust-lang/stdarch#1796 (stabilizing the runtime detection and intrinsics)
- rust-lang/rust#141964 (stdarch submodule update for the stabilization of the runtime detection and intrinsics)
As all of the required tasks have been done (adding the target features to rustc, implementing their runtime detection in std_detect and implementing the associated intrinsics in core_arch), these target features can be stabilized now.
cc `@rust-lang/lang`
cc `@rust-lang/libs-api` for the intrinsics and runtime detection
I don't think anyone else worked on this feature, so no one else to ping, maybe cc `@Amanieu.` I will send the reference pr soon.
