Remove semicolon from internal err macro
This macro is used in expression position (a match arm), and only
compiles because of #33953

Regardless of what happens with that issue, this makes the
usage of the macro less confusing at the call site.

675f114d95 Auto merge of #79106 - tmiasko:inline-hint, r=nagisa,eddyb
Fix setting inline hint based on `InstanceDef::requires_inline`

For instances where `InstanceDef::requires_inline` is true, an attempt
is made to set an inline hint though a call to the `inline` function.
The attempt is ineffective, since all attributes will be usually removed
by the second call.

Fix the issue by applying the attributes only once, with user provided
attributes having a priority when provided.

Closes #79108.

Handle empty matches cleanly in exhaustiveness checking

This removes the special-casing of empty matches that was done in `check_match`. This fixes most of https://github.com/rust-lang/rust/issues/55123.
Somewhat unrelatedly, I also made `_match.rs` more self-contained, because I think it's cleaner.

Rollup merge of #79158 - lcnr:lazy-norm-coerce, r=oli-obk
type is too big -> values of the type are too big

strictly speaking, `[u8; usize::MAX]` or even `[[[u128; usize::MAX]; usize::MAX]; usize::MAX]` are absolutely fine types as long as you don't try to deal with any values of it.

This error message seems to cause some confusion imo, for example in https://github.com/rust-lang/rust/pull/79135#issuecomment-729361380 so I would prefer us to be more precise here.

See the added test case which uses one of these types without causing an error.

Rollup merge of #79133 - pietroalbini:simplify-stage0, r=Mark-Simulacrum
bootstrap: use the same version number for rustc and cargo

Historically the stable tarballs were named after the version number ofthe specific tool, instead of the version number of Rust. For example, both of the following tarballs were part of the same release:

    rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz
    cargo-0.49.0-x86_64-unknown-linux-gnu.tar.xz

PR #77336 changed the dist code to instead use Rust's version number for all the tarballs, regardless of the tool they contain:

    rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz
    cargo-1.48.0-x86_64-unknown-linux-gnu.tar.xz

Because of that there is no need anymore to have a separate `cargo` field in `src/stage0.txt`, as the Cargo version will always be the same as the rustc version. This PR removes the field, simplifying the code and the maintenance work required while producing releases.

Rollup merge of #79039 - thomcc:weakly-relaxing, r=Amanieu
Tighten the bounds on atomic Ordering in std::sys::unix::weak::Weak

This moves reading this from multiple SeqCst reads to Relaxed read + Acquire fence if we are actually going to use the data.

Would love to avoid the Acquire fence, but doing so would need Ordering::Consume, which neither Rust, nor LLVM supports (a shame, since this fence is hardly free on ARM, which is what I was hoping to improve).

Rollup merge of #78785 - cuviper:weak-getrandom, r=m-ou-se
linux: try to use libc getrandom to allow interposition

We'll try to use a weak `getrandom` symbol first, because that allows
things like `LD_PRELOAD` interposition. For example, perf measurements
might want to disable randomness to get reproducible results. If the
weak symbol is not found, we fall back to a raw `SYS_getrandom` call.

Rollup merge of #78361 - DevJPM:master, r=workingjubilee
Updated the list of white-listed target features for x86

This PR both adds in-source documentation on what to look out for when adding a new (X86) feature set and [adds all that are detectable at run-time in Rust stable as of 1.27.0](https://github.com/rust-lang/stdarch/blob/master/crates/std_detect/src/detect/arch/x86.rs).

This should only enable the use of the corresponding LLVM intrinsics.
Actual intrinsics need to be added separately in rust-lang/stdarch.

It also re-orders the run-time-detect test statements to be more consistent
with the actual list of intrinsics whitelisted and removes underscores not present
in the actual names (which might be mistaken as being part of the name)

The reference for LLVM's feature names used is [this file](https://github.com/llvm/llvm-project/blob/master/llvm/include/llvm/Support/X86TargetParser.def).

This PR was motivated as the compiler end's part for allowing #67329 to be adressed over on rust-lang/stdarch

A follow up of https://github.com/rust-lang/rust-clippy/issues/6239#issuecomment-719100677.

`map_clone` works with not only `Iterator` but `Option` although not written in [doc](https://rust-lang.github.io/rust-clippy/master/#map_clone). Also, an example in the doc shows  a usage of dereferencing, but this isn't also written.
