This avoids pathological cases where chains of binops get progressively deeper.

Currently `f32_nan` and `f64_nan` are used to provide the `invalid_nan_comparison` lint. Since we have `f16_nan` and `f128_nan`, hook these up so the new float types get the same lints.
This makes it significantly easier to debug bugs of this kind.
…o we can get rid of a bunch of attributes
…ready stable the rest has their constness guarded by their usual feature gate
This is an API that naturally should exist as a combination of byte_offset_from and sub_ptr both existing (they showed up at similar times so this union was never made). Adding these is a logical (and perhaps final) precondition of stabilizing ptr_sub_ptr (rust-lang#95892).
rustc_target reexports a lot of things that are in rustc_abi, but that will be over soon and now is probably a good time to switch. Uses of rustc_target remain where they inquire about the target tuple.
…ukang Remove support for `-Zprofile` (gcov-style coverage instrumentation) Tracking issue: rust-lang#42524 MCP: rust-lang/compiler-team#798 --- This PR removes the unstable `-Zprofile` flag, which enables ”gcov-style” coverage instrumentation, along with its associated `-Zprofile-emit` configuration flag. (The profile flag predates and is almost entirely separate from the stable `-Cinstrument-coverage` flag.) Notably, the `-Zprofile` flag: - Is largely untested in-tree, having only one run-make test that does not check whether its output is correct or useful. - Has no known maintainer. - Has seen no push towards stabilization. - Has at least one severe regression reported in 2022 that apparently remains unaddressed. - rust-lang#100125 - Is confusingly named, since it appears to be more about coverage than performance profiling, and has nothing to do with PGO. - Is fundamentally limited by relying on counters auto-inserted by LLVM, with no knowledge of Rust beyond debuginfo.
…ristic-assignment-only, r=calebcartwright style-guide: Only use the new binop heuristic for assignments This avoids pathological cases where chains of binops get progressively deeper.
…k-sugg, r=WaffleLapkin Implement suggestion for never type fallback lints r? ```@WaffleLapkin``` Just opening this up for vibes; it's not done yet. I'd still like to make this suggestable in a few more cases before merge: - [x] Try to annotate `_` -> `()` - [x] Try to annotate local variables if they're un-annotated: `let x = ...` -> `let x: () = ...` - [x] Try to annotate the self type of a `Trait::method()` -> `<() as Trait>::method()`. The only other case we may want to suggest is a missing turbofish, like `f()` -> `f::<()>()`. That may be possible, but seems overly annoying. This partly addresses rust-lang#132358; the other half of fixing that would be to make the error message a bit better, perhaps just special casing the `?` operator 🤔 I don't think I'll do that part.
…, r=workingjubilee update offset_of! docs to reflect the stabilization of nesting this seems to have been missed.
…tings, r=jieyouxu Remove unncessary option for default rust-analyzer setting In favor of rust-lang/rust-analyzer#17888
…ouxu Add `f16` and `f128` to `invalid_nan_comparison` Currently `f32_nan` and `f64_nan` are used to provide the `invalid_nan_comparison` lint. Since we have `f16_nan` and `f128_nan`, hook these up so the new float types get the same lints.
…uillaumeGomez rustdoc: Directly use rustc_abi instead of reexports rustc_target reexports a lot of things that are in rustc_abi, but that will be over soon and now is probably a good time to switch. Uses of rustc_target remain where they inquire about the target tuple.
…=tgross35 Cleanup attributes around unchecked shifts and unchecked negation in const The underlying intrinsic is marked as "safe to expose on stable", so we shouldn't need any `rustc_allow_const_fn_unstable(unchecked_shifts)` anywhere. However, bootstrap rustc doesn't yet have the new const stability checks, so these changes only apply under `cfg(not(bootstrap))`.
