…onding impls exist
…w the extention of contexts by futures
…y removing a #[cfg(target_has_atomic = ptr)]
Co-authored-by: Mark Rousskov <[email protected]>
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

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.
