…ethercote use the type name instead of `Self` in constructor paths again Fixes rust-lang#163800 by restoring `Substructure.type_ident` and using it instead of `Self` for constructor paths in `Clone` and `Default`'s expansions. r? @nnethercote

… r=nnethercote perf:cache FFI safety results in improper_ctypes lint This PR cache FFI safety results in improper_ctypes lint . ImproperCTypesVisitor's cache field is recreated empty at every call site, so a struct type gets fully re-walked from scratch each time instead of once . The implementation here moves the cache onto ImproperCtypesLint, so it remembers types we already checked and found FFI-safe, so we don't check the same type again every time it shows up in another function. We only remember "safe" types, never "unsafe" ones. That way we never need to keep the actual type around, just a fingerprint of it.Thus it persists across a whole module worth of foreign items.
…tests, r=Urgau Move more `rustdoc-html` tests in the right location Follow-up of rust-lang#162372. r? @Urgau
…uppe cg_llvm: Avoid `as_c_char_ptr` in several places As noted in `rustc_codegen_llvm::ffi`: > Normally it's a good idea for Rust-side bindings to match the corresponding C-side function declarations as closely as possible. But when passing `&str` or `&[u8]` data as a pointer/length pair, it's more convenient to declare the Rust-side pointer as `*const c_uchar` instead of `*const c_char`. Both pointer types have the same ABI, and using `*const c_uchar` avoids the need for an extra cast from `*const u8` on the Rust side. The helper method `as_c_char_ptr` exists to make that extra cast more type-safe, but it's nicer to not need it all. In addition to making call sites a bit simpler, this adjustment also makes it harder to accidentally pass a nul-terminated string to a function expecting a pointer/length string, and vice-versa. There should be no change to compiler output.
…, r=folkertdev Add `has_reliable_f16b` for Arm Add the match arm for `has_reliable_f16b` for `Arch::Arm`. Through investigations in llvm/llvm-project#224867 there is decent enough support for Rusts `f16b` type on Arm targets. r? folkertdev
