…onding impls exist
…w the extention of contexts by futures
…y removing a #[cfg(target_has_atomic = ptr)]
Co-authored-by: Mark Rousskov <mark.simulacrum@gmail.com>
This also removes * impl From<&Context> for ContextBuilder * Context::try_waker() The from implementation is removed because now that wakers are always supported, there are less incentives to override the current context. Before, the incentive was to add Waker support to a reactor that didn't have any.
Makes the trait implementation documentation for arrays and slices appear more consistent.
Disable packed/unpacked options for riscv linux/android. Other riscv targets already only have the off option. The packed/unpacked options might be supported in the future. See upstream issue for more details: llvm/llvm-project#56642 Fixes rust-lang#110224
…rinsic signatures
The Rust LoongArch targets have been using the default LLVM code model so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak. As described in the "Code Model" section of LoongArch ELF psABI spec v20231219 [1], one can only make function calls as far as ±128MiB with the "normal" code model; this is insufficient for very large software containing Rust components that needs to be linked into the big text section, such as Chromium. Because: * we do not want to ask users to recompile std if they are to build such software, * objects compiled with larger code models can be linked with those with smaller code models without problems, and * the "medium" code model is comparable to the "small"/"normal" one performance-wise (same data access pattern; each function call becomes 2-insn long and indirect, but this may be relaxed back into the direct 1-insn form in a future LLVM version), but is able to perform function calls within ±128GiB, it is better to just switch the targets to the "medium" code model, which is also "medium" in LLVM-speak.

`std::error::Error` -> Trait Implementations: lifetimes consistency improvement This cleans up `std::error::Error` trait implementations lifetime inconsistency (`'static` -> `'a`) **Reasoning:** Trait implementations for `std::error::Error`, like: `impl From<&str> for Box<dyn Error + 'static, Global>` `impl<'a> From<&str> for Box<dyn Error + Sync + Send + 'a, Global>` use different lifetime annotations misleadingly implying using different life annotations here is a conscious, nonaccidental decision.

PartialEq, PartialOrd: update and synchronize handling of transitive chains It was brought up in https://internals.rust-lang.org/t/total-equality-relations-as-std-eq-rhs/19232 that we currently have a gap in our `PartialEq` rules, which this PR aims to close: > For example, with PartialEq's conditions you may have a = b = c = d ≠ a (where a and c are of type A, b and d are of type B). The second commit fixes rust-lang#87067 by updating PartialOrd to handle the requirements the same way PartialEq does.
make matching on NaN a hard error, and remove the rest of illegal_floating_point_literal_pattern These arms would never be hit anyway, so the pattern makes little sense. We have had a future-compat lint against float matches in general for a *long* time, so I hope we can get away with immediately making this a hard error. This is part of implementing rust-lang/rfcs#3535. Closes rust-lang#41620 by removing the lint. rust-lang/reference#1456 updates the reference to match.
…ulacrum Add LocalWaker and ContextBuilder types to core, and LocalWake trait to alloc. Implementation for rust-lang#118959.
…r=Mark-Simulacrum Use `<T, U>` for array/slice equality `impl`s Makes the trait implementation documentation for arrays and slices appear more consistent. [Example](https://doc.rust-lang.org/1.75.0/std/primitive.array.html): mixed `A`, `B`, and `U`.  This change makes them all `U`.
…piler-errors riscv only supports split_debuginfo=off for now Disable packed/unpacked options for riscv linux/android. Other riscv targets already only have the off option. The packed/unpacked options might be supported in the future. See upstream issue for more details: llvm/llvm-project#56642 Fixes rust-lang#110224
Assert that params with the same *index* have the same *name* Found this bug when trying to build libcore with the new solver, since it will canonicalize two params with the same index into *different* placeholders if those params differ by name.
Remove unused struct Detected by rust-lang#118257
