There are a handful of functions we can move out of the macro and to the
numeric traits as default implementations; do that here.
Additionally, add some bounds that make sense for completeness.
|
|
|
|
Currently there is a combination of names starting with
`multiprecision_`, `mp_` and `multiprec_`. Update so `multiprecision_`
is always used when a long form makes sense, `mp_` otherwise
(eliminating `multiprec_`).

With the `compiler-builtins` update to 0.1.137 [1], we now provide
symbols necessary to work with `f128` everywhere. This means that we are
no longer restricted to 64-bit linux, and can enable tests by default.
There are still a handful of platforms that need to remain disabled
because of bugs. This patch additionally disables the following:
1. MIPS [2]
2. 32-bit x86 [3]
Math support is still off by default since those symbols are not yet
available.

This updates to a new version of builtins that includes [1], which was
the last blocker to us enabling `f128` tests on all platforms 🎉.
With this update, also change to pinning the version with `=` rather
than using the default carat versioning. This is meant to ensure that
`compiler-builtins` does not get updated as part of the weekly
`Cargo.lock` update, since updates to this crate need to be intentional:
changes to rust-lang/rust and rust-lang/compiler-builtins sometimes need
to be kept in lockstep, unlike most dependencies, and sometimes these
updates can be problematic.

Modify `NonZero` documentation to reference the underlying integer type
This change updates the documentation for `NonZero` integer types to explicitly reference the underlying integer type each `NonZero` variant wraps, instead of using a general "integer" term.

Make `std::os::darwin` public
I'm not sure of the reasoning behind them not being public before, but I think they should be, just like `std::os::ios` and `std::os::macos` are public.
Additionally, I've merged their source code, as it was otherwise just a bunch of unnecessary duplication.
Ultimately, I've done this PR to fix `./x build library --target=aarch64-apple-tvos,aarch64-apple-watchos,aarch64-apple-visionos`, as that currently fails because of dead code warnings.

Yeet the `effects` feature, move it onto `const_trait_impl`
This PR merges the `effects` feature into the `const_trait_impl` feature. There's really no need to have two feature gates for one feature.
After this PR, if `const_trait_impl` **is** enabled:
* Users can use and define const traits
* `HostEffect` const conditions will be enforced on the HIR
* We re-check the predicates in MIR just to make sure that we don't "leak" anything during MIR lowering
And if `const_trait_impl` **is not** enabled:
* Users cannot use nor define const traits
* `HostEffect` const conditions are not enforced on the HIR
* We will raise a const validation error if we call a function that has any const conditions (i.e. const traits and functions with any `~const` in their where clasues)
This should be the last step for us to be able to enable const traits in the standard library. We still need to re-constify `Drop` and `Destruct` and stuff for const traits to be particularly *useful* for some cases, but this is a good step :D

add const_panic macro to make it easier to fall back to non-formatting panic in const
Suggested by `@tgross35`
r? `@tgross35`
|

Operations like is_aligned would return actively wrong results at compile-time,
i.e. calling it on the same pointer at compiletime and runtime could yield
different results. That's no good.
Instead of having hacks to make align_offset kind-of work in const-eval, just
use const_eval_select in the few places where it makes sense, which also ensures
those places are all aware they need to make sure the fallback behavior is
consistent.

better test for const HashMap; remove const_hash leftovers
The existing `const_with_hasher` test is kind of silly since the HashMap it constructs can never contain any elements. So this adjusts the test to construct a usable HashMap, which is a bit non-trivial since the default hash builder cannot be built in `const`. `BuildHasherDefault::new()` helps but is unstable (https://github.com/rust-lang/rust/issues/123197), so we also have a test that does not involve that type.
The second commit removes the last remnants of https://github.com/rust-lang/rust/issues/104061, since they aren't actually useful -- without const traits, you can't do any hashing in `const`.

Add LowerExp and UpperExp implementations to NonZero
Adds `LowerExp` and `UpperExp` trait implementations to `NonZero`, as discussed in rust-lang/libs-team#458.
I had to modify the macro to mark the new impls with a different rust version. Let me know if this is the right way to do it (first timer here!)

Implement `From<&mut {slice}>` for `Box/Rc/Arc<{slice}>`
ACP: https://github.com/rust-lang/libs-team/issues/424
New API:
```rust
impl<T: Clone> From<&mut [T]> for Box<[T]>
impl From<&mut str> for Box<str>
impl From<&mut CStr> for Box<CStr>
impl From<&mut OsStr> for Box<OsStr>
impl From<&mut Path> for Box<Path>
impl<T: Clone> From<&mut [T]> for Rc<[T]>
impl From<&mut str> for Rc<str>
impl From<&mut CStr> for Rc<CStr>
impl From<&mut OsStr> for Rc<OsStr>
impl From<&mut Path> for Rc<Path>
impl<T: Clone> From<&mut [T]> for Arc<[T]>
impl From<&mut str> for Arc<str>
impl From<&mut CStr> for Arc<CStr>
impl From<&mut OsStr> for Arc<OsStr>
impl From<&mut Path> for Arc<Path>
```
Since they are trait implementations, I think these are insta-stable.
As mentioned in https://github.com/rust-lang/libs-team/issues/424#issuecomment-2299415749, a crater run might be needed.

Migrate from string to enum matching and tie this to `CheckCtx::new`, so
no tests need to explicitly set ULP.

This prepares to eliminate some reliance on string matching but does not
yet make those changes.

get rid of a whole bunch of unnecessary rustc_const_unstable attributes
In general, when a `const fn` is still unstable, it doesn't need a `#[rustc_const_unstable]` attribute. The only exception is functions that internally use things that can't be used in stable const fn yet.
So this gets rid of a whole bunch of `#[rustc_const_unstable]` in libcore.

This contains:
1. Per-function and per-operation enums created by the proc macro
2. The `MathOp` trait which is implemented once per struct representing
a function
3. Submodules for each function, each containing a `Routine` struct that
implements `MathOp`

Currently the macro always provides `CFn`, `RustFn`, `RustArgs`, etc.
Change this so that:
1. This information must be explicily requested in the invocation.
2. There is a new `FTy` field available that emits a single float type,
rather than a tuple or signature.
Additionally, add two new macros that create enums representing function
names.

Remove unintended link
Since `#[link_section]` is enclosed in braces, it was being confused with a link during docs compilation.
This caused compilation to fail when running `x dist` since it emitted a warning regarding broken links.

Fix type reference in documents which was being confused with html tags.
Running `x dist` was failing due to it invoking commands with `-D warnings`, which emitted a warning about unclosed html tags.

library: fix some stability annotations
This PR updates some stability attributes to correctly reflect when some items actually got stabilized. Found while testing https://github.com/rust-lang/rust/pull/132481.
### `core::char` / `std::char`
In https://github.com/rust-lang/rust/pull/26192, the `core::char` module got "stabilized" for 1.2.0, but the `core` crate itself was still unstable until 1.6.0.
In https://github.com/rust-lang/rust/pull/49698, the `std::char` module was changed to a re-export of `core::char`, making `std::char` appear as "stable since 1.2.0", even though it was already stable in 1.0.0.
By marking `core::char` as stable since 1.0.0, the docs will show correct versions for both `core::char` (since 1.6.0) and `std::char` (since 1.0.0). This is also consistent with the stabilities of similar re-exported modules like `core::mem`/`std::mem` for example.
### `{core,std}::array` and `{core,std}::array::TryFromSliceError`
In https://github.com/rust-lang/rust/pull/58302, the `core::array::TryFromSliceError` type got stabilized for 1.34.0, together with `TryFrom`. At that point the `core::array` module was still unstable and a `std::array` re-export didn't exist, but `core::array::TryFromSliceError` could still be named due to https://github.com/rust-lang/rust/pull/95956 to existing yet.
Then, `core::array` got stabilized and `std::array` got added, first targeting 1.36.0 in https://github.com/rust-lang/rust/pull/60657, but then getting backported for 1.35.0 in https://github.com/rust-lang/rust/pull/60838.
This means that `core::array` and `std::array` actually got stabilized in 1.35.0 and `core::array::TryFromSliceError` was accessible through the unstable module in 1.34.0 -- mark them as such so that the docs display the correct versions.

feat(byte_sub_ptr): unstably add ptr::byte_sub_ptr
This is an API that naturally should exist as a combination of byte_offset_from and sub_ptr
both existing (they showed up at similar times so this union was never made). Adding these
is a logical (and perhaps final) precondition of stabilizing ptr_sub_ptr (https://github.com/rust-lang/rust/issues/95892).
Original PR by ``@Gankra`` (https://github.com/rust-lang/rust/pull/121919), I am just reviving it. The 2nd commit (with a small docs tweak) is by me.
