Implement accepted ACP for functions that isolate the most significant set bit and least significant set bit on unsigned, signed, and NonZero integers. Add function `isolate_most_significant_one` Add function `isolate_least_significant_one` Add tests
I was always confused about what is being built, since nothing was printed in the log :)
The only case where can_reuse_cratenum could have been false in the past are rustc plugins, support for which has been removed over a year ago now. Nowadays the only case where locator.tuple is not target_triple is when loading a proc macro, in which case we also set can_reuse_cratenum to true. As such it is always true and we can remove some dead code.
…ows 7 Would otherwise fail there. The Windows7-specific parts were left pretty much untouched by the changes introduced by 51df98d, so it is expected that these tests fail under Windows 7 as they were probably written to run under Windows 10+ only.

Implement feature `isolate_most_least_significant_one` for integer types Accepted ACP - rust-lang/libs-team#467 Tracking issue - rust-lang#136909 Implement ACP for functions that isolate the most significant set bit and least significant set bit on unsigned, signed, and `NonZero` integers. Add function `isolate_most_significant_one` Add function `isolate_least_significant_one` --- This PR adds the following impls ```rust impl {u8, u16, u32, u64, u128, usize} { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } impl {i8, i16, i32, i64, i128, isize} { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } impl NonZeroT { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } ``` Example behavior ```rust assert_eq!(u8::isolate_most_significant_one(0b01100100), 0b01000000); assert_eq!(u8::isolate_least_significant_one(0b01100100), 0b00000100); ```
…, r=lcnr Prune dead regionck code We never encounter `ObligationCauseCode`s that correspond to region obligations that originate from "within" a body, since we don't do HIR regionck anymore on bodies. So prune some dead code.
…, r=Nadrieril Use `edition = "2024"` in the compiler (redux) Most of this is binding mode changes, which I fixed by running `x.py fix`. Also adds some miscellaneous `unsafe` blocks for new unsafe standard library functions (the setenv ones), and a missing `unsafe extern` block in some enzyme codegen code, and fixes some precise capturing lifetime changes (but only when they led to errors). cc ``@ehuss`` ``@traviscross``
Ferris 🦀 Identifier naming conventions
You cannot use Ferris as an identifier in Rust, this code will suggest to correct the 🦀 to `ferris`:
```rs
fn main() {
let 🦀 = 4;
}
```
But it also suggests to correct to `ferris` in these cases, too:
```rs
struct 🦀 {}
fn main() {}
```
^ suggests: `ferris`
~ with this PR: `Ferris`
```rs
static 🦀: &str = "ferris!";
fn main() {}
```
^ suggests: `ferris`
~ with this PR: `FERRIS`
This is my first pull requests here!

…antics-tests-under-win7, r=ChrisDenton Fix(lib/fs/tests): Disable rename POSIX semantics FS tests under Windows 7 Would otherwise fail there.

… r=workingjubilee Use StableHasher + Hash64 for dep_tracking_hash This is similar to rust-lang#137095. We currently have a +/- 1 byte jitter in the size of dep graphs reported on perf.rust-lang.org. I think this fixes that jitter. When I introduced `Hash64`, I wired it through most of the compiler by making it an output of `StableHasher::finalize` then fixing the compile errors. I missed this case because the `u64` hash in this function is being produced by `DefaultHasher` instead. That seems pretty sketchy because the code seems confident that the hash needs to be stable, and we have a mechanism for stable hashing that we weren't using here.
…ble, r=chenyukang jubilee cleared out the review queue despite some things coming in during.
