Instead of relying on a command line parameter, detect if a target
is able to unwind or not.
Ignore tests that require unwinding on targets that don't support it.
There's a bunch of these checks because of special handing for ZSTs in various unsafe implementations of stuff.
This lets them be `T::IS_ZST` instead of `mem::size_of::<T>() == 0` every time, making them both more readable and more terse.
*Not* proposed for stabilization at this time. Would be `pub(crate)` except `alloc` wants to use it too.
(And while it doesn't matter now, if we ever get something like 85836 making it a const can help codegen be simpler.)
Improve the help message for an invalid calling convention
Fixes https://github.com/rust-lang/rust/issues/93601
I mostly followed the suggestions of `@nagisa` in that issue, ~~however, I wasn't sure how to check stability for the suggestion of "Do not suggest CCs that cannot be used due to them being unstable and feature not being enabled", so I did not implement that point.~~
I haven't contributed to rustc much, please feel free to point out suggestions! For example, the `.map(|s| Symbol::intern(s)).collect::<Vec<_>>()` seems pretty gross performance-wise, but maybe that's OK in error reporting code.
Allow full relro on powerpc64-unknown-linux-gnu
This was previously limited to partial relro, citing issues on RHEL6,
but that's no longer a supported platform since #95026. We have long
been enabling full relro in RHEL7's own Rust builds for ppc64, without
trouble, so it should be fine to drop this workaround.
rustdoc: remove unnecessary `max-width` on headers
This code was added in 003b2bc1c6 to prevent these headers from overlapping `.out-of-band` side items. That stopped being a problem when 3f92ff34b5 switched rustdoc over to using `float`, rather than `position: absolute`, to implement this.
Distribute rust-docs-json via rustup.
I am not 100% sure on how to treat `rust-json-docs` in `target_host_combination`. I went along with a similar strategy to the one used for `rust-docs`, but looking for guidance there.
Migrated the rustc_passes annotation without effect diagnostic infrastructure
Small change to move the validation for annotations to the new diagnostic infrastructure.
Note if mismatched types have a similar name
If users get a type error between similarly named types, it will point out that these are actually different types, and where they were defined.
Split out async_fn_in_trait into a separate feature
PR #101224 added support for async fn in trait desuraging behind the `return_position_impl_trait_in_trait` feature.
Split this out so that it's behind its own feature gate, since async fn in trait doesn't need to follow the same stabilization schedule.
rustdoc: remove no-op CSS `.location:empty { border: none }`
This rule was added in 2bb2a2975f to remove a border placed around the location when it's empty. That rule was removed in 6a5f8b1aef, so this rule does nothing.
Extend const_convert with const {FormResidual, Try} for ControlFlow.
Very small change so I just used the existing `const_convert` feature flag. #88674
Newly const API:
```
impl<B, C> const ops::Try for ControlFlow<B, C>;
impl<B, C> const ops::FromResidual for ControlFlow<B, C>;
```
`@usbalbin` I hope it is ok that I added to your feature.
Const unification is already infallible, remove the error handling logic
r? `@lcnr`
is this expected to be used in the future? Right now it is dead code.
rustdoc: remove no-op CSS `.content .item-info { position: relative }`
This rule was added to help position the marker line in 110e7270ab, which was a `position: absolute` pseudo-element that relied on its parent to put it in the right spot. (it was changed from a line to an arrow in 1ffb9cf8d7, then a different arrow in ae3a53ff58).
The arrow was removed in 73d0f7c7b6, so the `relative` position is no longer necessary.
rustdoc: clean up line numbers on code examples
* First commit switches from `display: inline-flex; width: 100%` to `display: flex`.
`display: inline-flex` was used as part of e961d397ca, the original commit that added these line numbers. Does anyone know why it was done this way?
* Second commit makes it so that toggling this checkbox will update the page in real time, just like changing themes does.

This rule was added in 2bb2a2975f to remove a
border placed around the location when it's empty. That rule was removed in
6a5f8b1aef, so this rule does nothing.
Inline SyntaxContext in both encoded span representation.
The current interned representation for spans does not use the `ctxt_or_zero: u16` field. This PR proposes to use this field to store the `SyntaxContext` of the interned span instead. When `ctxt_or_zero` and the interned span's `ctxt` don't match, the inlined one takes precedence.
This allows to implement `Span::ctxt` and `Span::with_ctxt` with much less probability to access the interner. Those functions are used a lot for hygiene, so this may be worth it.

Added which number is computed in compute_float.
The original comment was very elaborate but ultimately did not mention at all what is being computed using parameters `w, q`, only referencing an external article for the algorithm.
rustc_transmute: fix big-endian discriminants
I noticed that some new tests were failing in Fedora on s390x only, which usually means there's a problem with big-endian, and sure enough there's a FIXME(``@jswrenn)`` for that in `rustc_transmute`. This patch implements the appropriate consideration for target endianness, rather than using native (host) endian.
