For half-open ranges, specifies that the upper bound cannot be the minimum. Also specify that this only applies to range patterns and not also expressions.
This reduces check times for miri from 2m15s to 20s. And reduces check times for miri with --compile-time-deps from 1m50s to 7s. This makes rust-analyzer start a lot faster after switching branches.
…flelapkin Fix ICE when applying test macro to crate root This PR does a couple of things. First of all, I found [an ICE](https://play.rust-lang.org/?version=stable&mode=debug&edition=2024&gist=a733a7f3d223e1a9712e44b571f3e5cf) that happens when applying `#![core::prelude::v1::test]` to the crate root. This is caused by the test macro not expanding to an item when `--test` isn't applied. For the crate root, that means it deletes the crate.... The fix now first does target checking, and only if the target is valid discards the item when `--test` isn't applied. The discarding is, I think, important for perf. The problem with this PR is that it means that `#[test]` applied to structs previously would give no errors unless `--test` is applied! That sounds like a bug to me, but maybe we should crater run it just in case, since technically that's a breaking change. Errors in such items wouldn't be reported previously. Also fixed a smol diagnostics bug with `#[bench]`'s error messages refering to `#[test]` accidentally. r? noratrieb (since I already explained you a bunch, feel free to re-assign) Fixesrust-lang#114920

Use `TypingMode::PostAnalysis` in `try_evaluate_const` As mentioned in rust-lang#148698 (comment), we should use ``TypingMode::PostAnalysis`` for that path. ````@BoxyUwU```` prefer the match in ``try_evaluate_const`` to be exhaustive, so I also included that in this PR :3
…lacrum std: don't call `current_os_id` from signal handler `current_os_id` is not always async-signal-safe depending on the platform, hence it may not be called from the SIGSEGV handler. Instead, store the thread ID along with the thread name during setup. With rust-lang#144465 merged, this information is available even before the thread main function.
…, r=lqd,oli-obk CTFE: avoid emitting a hard error on generic normalization failures Fixesrust-lang#149081. The fix is quite unsatisfying and should not be necessary, cc rust-lang#149283. That change is significantly more involved. This temporary fix introduces some unnecessary complexity and may hide other type system bugs. cc ````@rust-lang/types```` I think we should try to fix issue rust-lang#149283 in the near future and then remove this hack again. I originally intended a more targeted fix. I wanted to skip evaluating constants in MIR opts if their body was polymorphic and the current generic arguments still reference generic parameters. Notes from looking into this: - we only fetch the MIR in the `eval_to_allocation_raw` query - figuring out which MIR to use is hard - dealing with trivial consts is annoying - need to resolve instances for associated consts - implementing this by hand is hard - inlining handles this issue by bailing on literally all normalization failures, even the ones that imply an unsoundness - `try_normalize_after_erasing_regions` generally does two things - deal with ambiguity after inlining - deal with error tainting issues (please don't, we should stop doing that) - CTFE could be changed to always silently ignore normalization failures if we're in a generic body - hides actual bugs <- went with this option r? types

Additional test for uN::{gather,scatter}_bits
Feature gate: #![feature(uint_gather_scatter_bits)]
Tracking issue: rust-lang#149069
Accepted ACP: rust-lang/libs-team#695 (comment)
Adds an additional runtime test for `uN::gather_bits` and `uN::scatter_bits` in coretests. They are each other's inverses in a sense, so a shared test can test both with relative ease.

Fix mailmap issue My name and username got separated in thanks.rust-lang.org, probably due to me changing my email in Github about a month ago.
