Add newtypes for bool fields/params/return types
Fixed all the cases of this found with some simple searches for `*/ bool` and `bool /*`; probably many more
Stabilize `cfg_target_abi`
This stabilizes the `cfg` option called `target_abi`:
```rust
#[cfg(target_abi = "eabihf")]
```
Tracking issue: #80970fixes#78791resolves#80970
Add `#[rustc_no_mir_inline]` for standard library UB checks
should help with #121110 and also with #120848
Because the MIR inliner cannot know whether the checks are enabled or not, so inlining is an unnecessary compile time pessimization when debug assertions are disabled. LLVM knows whether they are enabled or not, so it can optimize accordingly without wasting time.

promotion: don't promote int::MIN / -1
Looks like I entirely forgot about this case when adding the div-by-zero check, which was supposed to ensure that we never promote operations that can fail...

This is a breaking change, so needs a crater run.

match lowering: Split off `test_candidates` into several functions and improve comments
The logic of `test_candidates` has three steps: pick a test, sort the candidates, and generate code for everything. So I split it off into three methods.
I also ended up reworking the comments that explain the algorithm. In particular I added detailed examples. I removed the digression about https://github.com/rust-lang/rust/issues/29740 because it's no longer relevant to how the code is structured today.

The goal is to enable the lint by default at one point. There are many cases where it needs to be allowed. But here we don't need to allow it. We can simply fix it.
I don't want to enable the lint in the file, because I don't want the "default size threshold for when a value is OK to move" to be duplicated in many places. We'll want the threshold in one central place once we enable it by default.
Account for RPITIT in E0310 explicit lifetime constraint suggestion
When given
```rust
trait Original {
fn f() -> impl Fn();
}
trait Erased {
fn f(&self) -> Box<dyn Fn()>;
}
impl<T: Original> Erased for T {
fn f(&self) -> Box<dyn Fn()> {
Box::new(<T as Original>::f())
}
}
```
emit do not emit an invalid suggestion restricting the `Trait::{opaque}` type in a `where` clause:
```
error[E0310]: the associated type `<T as Original>::{opaque#0}` may not live long enough
--> $DIR/missing-static-bound-from-impl.rs:11:9
|
LL | Box::new(<T as Original>::f())
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| |
| the associated type `<T as Original>::{opaque#0}` must be valid for the static lifetime...
| ...so that the type `impl Fn()` will meet its required lifetime bounds
```
Partially address #119773. Ideally we'd suggest modifying `Erased::f` instead.

It looks like LLD will detect object files being either 32 or 64-bit
depending on any memory present. LLD will additionally reject 32-bit
objects during a 64-bit link. Previously metadata objects did not have
any memories in them which led LLD to conclude they were 32-bit objects
which broke 64-bit targets for wasm.
This commit fixes this by ensuring that for 64-bit targets there's a
memory object present to get LLD to detect it's a 64-bit target.
Additionally this commit moves away from a hand-crafted wasm encoder to
the `wasm-encoder` crate on crates.io as the complexity grows for the
generated object file.
Closes#121460
coverage: Rename `is_closure` to `is_hole`
Extracted from #121433, since I was having second thoughts about some of the other changes bundled in that PR, but these changes are still fine.
---
When refining covspans, we don't specifically care which ones represent closures; we just want to know which ones represent "holes" that should be carved out of other spans and then discarded.
(Closures are currently the only source of hole spans, but in the future we might want to also create hole spans for nested items and inactive `#[cfg(..)]` regions.)

Don't ICE on anonymous struct in enum variant
Fixes#121446
Computing `adt_def` for the anon struct calls `adt_def` on the parent to find its repr. If the parent is a non-item (e.g. an enum variant) we should have already emitted at least one error, so we just use the repr of the anonymous struct to avoid an ICE.

mark `min_exhaustive_patterns` as complete
This is step 1 and 2 of my [proposal](https://github.com/rust-lang/rust/issues/119612#issuecomment-1918097361) to move `min_exhaustive_patterns` forward. The vast majority of in-tree use cases of `exhaustive_patterns` are covered by `min_exhaustive_patterns`. There are a few cases that still require `exhaustive_patterns` in tests and they're all behind references.

Thank you.
This is part of changing attributes to only_local. I hope get your opinion whether I should split into multiple PRs, or submit in one.
According to [try to not rely on attributes from extern crates](https://github.com/rust-lang/compiler-team/issues/505) and lcnr's guidance.
