Spelling library Split per https://github.com/rust-lang/rust/pull/110392 I can squash once people are happy w/ the changes. It's really uncommon for large sets of changes to be perfectly acceptable w/o at least some changes. I probably won't have time to respond until tomorrow or the next day

2023-04-25Rollup merge of #110649 - arlosi:fix_no_global_oom_handling, r=Mark-SimulacrumMatthias Krüger-1/+0
Fix no_global_oom_handling build `provide_sorted_batch` in core is incorrectly marked with `#[cfg(not(no_global_oom_handling))]` which prevents core from building with the cfg enabled. Nothing in `core` allocates memory (including this function). The `cfg` gate is incorrect. cc ``@dpaoliello`` r? ``@wesleywiser`` The cfg was added by #107191

2023-04-25Auto merge of #110389 - mazong1123:add-shortcut-for-grisu3, r=Mark-Simulacrumbors-0/+43
Add shortcut for Grisu3 algorithm. While Grisu3 is way more faster for most numbers compare to Dragon4, the fall back to Dragon4 procedure for certain numbers could cause some performance regressions compare to use Dragon4 directly. Mitigating the regression caused by falling back is important for a largely used core library. In Grisu3 algorithm implementation, there's a shortcut to jump out earlier when the fractional or integrals cannot meet the requirement of requested digits. This could significantly improve the performance of converting floating number to string as it falls back even without starting trying the algorithm. The original idea is from the [.NET implementation](https://github.com/dotnet/runtime/blob/main/src/libraries/System.Private.CoreLib/src/System/Number.Grisu3.cs#L602-L615) and the code was originally added in [this PR](https://github.com/dotnet/coreclr/pull/14646#issuecomment-350942050). This shortcut has been shipped long time ago and has been proved working. Fix #110129

2023-04-24Rollup merge of #110706 - scottmcm:transmute_unchecked, r=oli-obkMatthias Krüger-19/+31
Add `intrinsics::transmute_unchecked` This takes a whole 3 lines in `compiler/` since it lowers to `CastKind::Transmute` in MIR *exactly* the same as the existing `intrinsics::transmute` does, it just doesn't have the fancy checking in `hir_typeck`. Added to enable experimenting with the request in <https://github.com/rust-lang/rust/pull/106281#issuecomment-1496648190> and because the portable-simd folks might be interested for dependently-sized array-vector conversions. It also simplifies a couple places in `core`. See also https://github.com/rust-lang/rust/pull/108442#issuecomment-1474777273, where `CastKind::Transmute` was added having exactly these semantics before the lang meeting (which I wasn't in) independently expressed interest.

2023-04-22Auto merge of #109507 - Amanieu:panic-oom-payload, r=davidtwcobors-13/+1
Report allocation errors as panics OOM is now reported as a panic but with a custom payload type (`AllocErrorPanicPayload`) which holds the layout that was passed to `handle_alloc_error`. This should be review one commit at a time: - The first commit adds `AllocErrorPanicPayload` and changes allocation errors to always be reported as panics. - The second commit removes `#[alloc_error_handler]` and the `alloc_error_hook` API.

2023-04-22Auto merge of #106934 - DrMeepster:offset_of, r=WaffleLapkinbors-0/+233
Add offset_of! macro (RFC 3308) Implements https://github.com/rust-lang/rfcs/pull/3308 (tracking issue #106655) by adding the built in macro `core::mem::offset_of`. Two of the future possibilities are also implemented: * Nested field accesses (without array indexing) * DST support (for `Sized` fields) I wrote this a few months ago, before the RFC merged. Now that it's merged, I decided to rebase and finish it. cc `@thomcc` (RFC author)

`provide_sorted_batch` in core is incorrectly marked with `#[cfg(not(no_global_oom_handling))]` which prevents core from building with the cfg enabled. Nothing in core allocates memory including this function, so the `cfg` gate is incorrect.

2023-04-20Implement `Neg` for signed non-zero integers.John Millikin-3/+34
Negating a non-zero integer currently requires unpacking to a primitive and re-wrapping. Since negation of non-zero signed integers always produces a non-zero result, it is safe to implement `Neg` for `NonZeroI{N}`. The new `impl` is marked as stable because trait implementations for two stable types can't be marked unstable.

2023-04-19std: make `Debug` representations of `[Lazy, Once]*[Cell, Lock]` consistent ↵joboet-18/+10
with `Mutex` and `RwLock` `Mutex` prints `<locked>` as a field value when its inner value cannot be accessed, but the lazy types print a fixed string like "`OnceCell(Uninit)`". This could cause confusion if the inner type is a unit type named `Uninit` and does not respect the pretty-printing flag. With this change, the format message is now "`OnceCell(<uninit>)`", consistent with `Mutex`.
