The new implementation allows some `memcpy`s to be optimized away, so the uninit value in ui/sanitize/memory.rs is constructed directly onto the return place. Therefore the sanitizer now says that the value is allocated by `main` rather than `random`.
Implement `black_box` using intrinsic Introduce `black_box` intrinsic, as suggested in rust-lang#87590 (comment). This is still codegenned as empty inline assembly for LLVM. For MIR interpretation and cranelift it's treated as identity. cc `@Amanieu` as this is related to inline assembly cc `@bjorn3` for rustc_codegen_cranelift changes cc `@RalfJung` as this affects MIRI r? `@nagisa` I suppose
…agisa,eddyb Add c_enum_min_bits target spec field, use for arm-none and thumb-none targets Fixes rust-lang#87917 <s>Haven't tested this yet, still playing around.</s> This seems to fix the issue.
…-formatting, r=petrochenkov Improve formatting of closure capture migration suggestion for multi-line closures. Fixes rust-lang#87952 Before: ``` help: add a dummy let to cause `a` to be fully captured | 5 ~ let _ = || { let _ = &a; 6 + dbg!(a.0); 7 ~ }; | ``` After: ``` help: add a dummy let to cause `a` to be fully captured | 5 ~ let _ = || { 6 + let _ = &a; 7 + dbg!(a.0); 8 ~ }; | ```
…stebank Silence non_fmt_panic from external macros. This stops the non_fmt_panic lint from triggering if a macro from another crate is entirely responsible. In those cases there's nothing that the current crate can/should do. See also rust-lang#87621 (comment)
