The type inference of argument-position closures and async blocks
regressed in 1.70 as the evaluation order of async blocks changed, as
they are not implicitly wrapped in an identity-function anymore.
Fixes#112225 by making sure the evaluation order stays the same as it
used to.
Revert "Add mandatory panic contexts to all threadpool tasks"
Reverts rust-lang/rust-analyzer#14965
This won't quite work actually given the use of `catch_unwind` in some of these
Add mandatory panic contexts to all threadpool tasks
the diagnostics task is panicking I think, but without this you can't really tell because the stack trace ends in a generic iterator fold call instead of something specific.
Only check inlining counter after recursing.
This PR aims to reduce the strength of https://github.com/rust-lang/rust/pull/105119 even more.
In the current implementation, we check the inline count before recursing. This means that we never actually reach inlining depth 3.
This PR checks the counter after recursion, to give a chance to inline at depth >= 3.

update Miri
Also adjust Miri's compiletest a little: in pre-subtree days we added `-A unused -Astable-features` to have the Miri toolstate break less often. But nowadays it just causes confusion when Miri CI works in rustc but fails on the Miri side so let's get rid of this difference.

Fix false positives of `need-mut` emerged from #14955
There are still 5 `need-mut` false positives on self, all related to `izip!` macro hygenic issue. I will try to do something about that before monday release.

only suppress coercion error if type is definitely unsized
we previously suppressed coercion errors when the return type was `dyn Trait` because we expect a far more descriptive `Sized` trait error to be emitted instead, however the code that does this suppression does not consider where-clause predicates since it just looked at the HIR. let's do that instead by creating an obligation and checking if it may hold.

Add other workspaces to `linkedProjects` in rust_analyzer_settings
This makes go-to-definition, etc. work in cg_clif, cg_gcc, rust-analyzer, and src/tools/x.
Fix codegen test suite for bare-metal-like targets
For Ferrocene I needed to run the test suite for custom target with no unwinding and static relocation. Running the tests uncovered ~20 failures due to the test suite not accounting for these options. This PR fixes them by:
* Fixing `CHECK`s to account for functions having extra LLVM IR attributes (in this case `nounwind`).
* Fixing `CHECK`s to account for the `dso_local` LLVM IR modifier, which is [added to every item when relocation is static](f3d597b31c/compiler/rustc_codegen_llvm/src/mono_item.rs (L139-L142)).
* Fixing `CHECK`s to account for missing `uwtables` attributes.
* Added the `needs-unwind` attributes for tests that are designed to check unwinding.
There is no part of Rust CI that checks this unfortunately, and testing whether the PR works locally is kinda hard because you need a target with std enabled but no unwinding and static relocations. Still, this works in my local testing, and if future PRs accidentally break this Ferrocene will take care of sending followup PRs.
Option::map_or_else: Show an example of integrating with Result
Moving this from https://github.com/rust-lang/libs-team/issues/59 where an API addition was rejected. But I think it's valuable to add this example to the documentation at least.
suggest `Option::as_deref(_mut)` on type mismatch in option combinator if it passes typeck
Fixes#106342.
This adds a suggestion to call `.as_deref()` (or `.as_deref_mut()` resp.) if typeck fails due to a type mismatch in the function passed to an `Option` combinator such as `.map()` or `.and_then()`.
For example:
```rs
fn foo(_: &str) {}
Some(String::new()).map(foo);
```
The `.map()` method requires its argument to satisfy `F: FnOnce(String)`, but it received `fn(&str)`, which won't pass. However, placing a `.as_deref()` before the `.map()` call fixes this since `&str == &<String as Deref>::Target`
rust-lld is not located in the same directory as the other binaries that
point to ../lib, but in a deeper directory in lib. So we need to point
a few layers up for rust-lld to find the LLVM shared library without
rustup's LD_LIBRARY_PATH overrides.
add unchecked_shl test
https://github.com/rust-lang/rust/pull/112238 made me realize that we have a test for add,sub,mul,shr but not shl. Add the missing test. Also name the existing tests more consistently.
QNX Neutrino: exponential backoff when fork/spawn needs a retry
Fixes#108594: When retrying, sleep with an exponential duration. When sleep duration is lower than minimum possible sleeping time, yield instead (this will not be often due to the exponential increase of duration).
Minimum possible sleeping time is determined using `libc::clock_getres` but only when spawn/fork failed the first time in a request. This is cached using a LazyLock.

The new dependencies come from `tempfile@3.5.0` which adds the dependency on `rustix`
