format macro argument parsing fix When the character next to `{}` is "shifted" (when mapping a byte index in the format string to span) we should avoid shifting the span end index, so first map the index of `}` to span, then bump the span, instead of first mapping the next byte index to a span (which causes bumping the end span too much). Regression test added. Fixes #83344 --- r? ```@estebank```

Generalize and inline slice::fill specializations This makes the memset specialization applicable to more types. And since the code now lives in a generic method it is also eligible for cross-crate inlining which should fix #83235

Add IEEE 754 compliant fmt/parse of -0, infinity, NaN This pull request improves the Rust float formatting/parsing libraries to comply with IEEE 754's formatting expectations around certain special values, namely signed zero, the infinities, and NaN. It also adds IEEE 754 compliance tests that, while less stringent in certain places than many of the existing flt2dec/dec2flt capability tests, are intended to serve as the beginning of a roadmap to future compliance with the standard. Some relevant documentation is also adjusted with clarifying remarks. This PR follows from discussion in https://github.com/rust-lang/rfcs/issues/1074, and closes #24623. The most controversial change here is likely to be that -0 is now printed as -0. Allow me to explain: While there appears to be community support for an opt-in toggle of printing floats as if they exist in the naively expected domain of numbers, i.e. not the extended reals (where floats live), IEEE 754-2019 is clear that a float converted to a string should be capable of being transformed into the original floating point bit-pattern when it satisfies certain conditions (namely, when it is an actual numeric value i.e. not a NaN and the original and destination float width are the same). -0 is given special attention here as a value that should have its sign preserved. In addition, the vast majority of other programming languages not only output `-0` but output `-0.0` here. While IEEE 754 offers a broad leeway in how to handle producing what it calls a "decimal character sequence", it is clear that the operations a language provides should be capable of round tripping, and it is confusing to advertise the f32 and f64 types as binary32 and binary64 yet have the most basic way of producing a string and then reading it back into a floating point number be non-conformant with the standard. Further, existing documentation suggested that e.g. -0 would be printed with -0 regardless of the presence of the `+` fmt character, but it prints "+0" instead if given such (which was what led to the opening of #24623). There are other parsing and formatting issues for floating point numbers which prevent Rust from complying with the standard, as well as other well-documented challenges on the arithmetic level, but I hope that this can be the beginning of motion towards solving those challenges.

Document that the SocketAddr memory representation is not stable Intended to help out with #78802. Work has been put into finding and fixing code that assumes the memory layout of `SocketAddrV4` and `SocketAddrV6`. But it turns out there are cases where new code continues to make the same assumption ([example](https://github.com/spacejam/seaslug/commit/96927dc2b7b918860a79c4eb6336051e52c6137a#diff-917db3d8ca6f862ebf42726b23c72a12b35e584e497ebdb24e474348d7c6ffb6R610-R621)). The memory layout of a type in `std` is never part of the public API. Unless explicitly stated I guess. But since that is invalidly relied upon by a considerable amount of code for these particular types, it might make sense to explicitly document this. This can be temporary. Once #78802 lands it does not make sense to rely on the layout any longer, and this documentation can also be removed.

Make # pretty print format easier to discover # Rationale: I use (cargo cult?) three formats in rust: `{}`, debug `{:?}`, and pretty-print debug `{:#?}`. I discovered `{:#?}` in some blog post or guide when I started working in Rust. While `#` is documented I think it is hard to discover. So taking the good advice of ```@carols10cents``` I am trying to improve the docs with a PR As a reminder "pretty print" means that where `{:?}` will print something like ``` foo: { b1: 1, b2: 2} ``` `{:#?}` will prints something like ``` foo { b1: 1 b2: 3 } ``` # Changes Add an example to `fmt` to try and make it easier to discover `#`

Ban custom inner attributes in expressions and statements Split out from https://github.com/rust-lang/rust/pull/82608 Custom inner attributes are unstable, so this won't break any stable users. This allows us to speed up token collection, and avoid a redundant call to `collect_tokens_no_attrs` when parsing an `Expr` that has outer attributes. r? `@petrochenkov`

Import small cold functions The Rust code is often written under an assumption that for generic methods inline attribute is mostly unnecessary, since for optimized builds using ThinLTO, a method will be code generated in at least one CGU and available for import. For example, deref implementations for Box, Vec, MutexGuard, and MutexGuard are not currently marked as inline, neither is identity implementation of From trait. In PGO builds, when functions are determined to be cold, the default multiplier of zero will stop the import, no matter how trivial the implementation. Increase slightly the default multiplier from 0 to 0.1. r? `@ghost`

Refactor #82270 as lint instead of an error This PR fixes several issues with #82270 which generated an error when `.intel_syntax` or `.att_syntax` was used in inline assembly: - It is now a warn-by-default lint instead of an error. - The lint only triggers on x86. `.intel_syntax` and `.att_syntax` are only valid on x86. - The lint no longer provides machine-applicable suggestions for two reasons: - These changes should not be made automatically since changes to assembly code can be very subtle. - The template string is not always just a string: it can contain macro invocation (`concat!`), raw strings, escape characters, etc. cc ``@asquared31415``

Rework rustdoc const type This PR is mostly about two things: 1. Not storing some information in the `clean::Constant` type 2. Using `TyCtxt` in the formatting (which we will need in any case as we move forward in any case). Also: I'm very curious of the perf change in here. Thanks a lot `@danielhenrymantilla` for your `Captures` idea! It allowed me to solve the lifetime issue completely. :) r? `@jyn514`
