With this commit, the examples for exp_m1 would fail if x.exp() - 1.0 is used instead of x.exp_m1().
With this commit, the examples for ln_1p would fail if (x + 1.0).ln() is used instead of x.ln_1p().
When calling a function that doesn't exist inside of a trait's associated `fn`, and another associated `fn` in that trait has that name, suggest calling it with the appropriate fully-qualified path. Expand the label to be more descriptive. Prompted by the following user experience: https://users.rust-lang.org/t/cannot-find-function/50663

Directly casting the opaque pointer was [reported] to cause an
"incomplete type" error with GCC 9.3:

A simple `unwrap` fixes the issue.
Otherwise code like this
#![no_implicit_prelude]
fn main() {
::std::todo!();
::std::unimplemented!();
}
will fail to compile, which is unfortunate and presumably unintended.
This changes many invocations of `panic!` in a `macro_rules!` definition
to invocations of `$crate::panic!`, which makes the invocations hygienic.
Note that this does not make the built-in macro `assert!` hygienic.

… r=KodrAus Add std::panic::panic_any. The discussion of rust-lang#67984 lead to the conclusion that there should be a macro or function separate from `std::panic!()` for throwing arbitrary payloads, to make it possible to deprecate or disallow (in edition 2021) `std::panic!(arbitrary_payload)`. Alternative names: - `panic_with!(..)` - ~~`start_unwind(..)`~~ (panicking doesn't always unwind) - `throw!(..)` - `panic_throwing!(..)` - `panic_with_value(..)` - `panic_value(..)` - `panic_with(..)` - `panic_box(..)` - `panic(..)` The equivalent (private, unstable) function in `libstd` is called `std::panicking::begin_panic`. I suggest `panic_any`, because it allows for any (`Any + Send`) type. _Tracking issue: #78500_
…ge, r=pnkfelix Implement rustc side of report-future-incompat cc rust-lang#71249 This is an alternative to @pnkfelix's initial implementation in https://github.com/pnkfelix/rust/commits/prototype-rustc-side-of-report-future-incompat (mainly because I started working before seeing that branch 😄 ). My approach outputs the entire original `Diagnostic`, in a way that is compatible with incremental compilation. This is not yet integrated with compiletest, but can be used manually by passing `-Z emit-future-incompat-report` to `rustc`. Several changes are made to support this feature: * The `librustc_session/lint` module is moved to a new crate `librustc_lint_defs` (name bikesheddable). This allows accessing lint definitions from `librustc_errors`. * The `Lint` struct is extended with an `Option<FutureBreakage>`. When present, it indicates that we should display a lint in the future-compat report. `FutureBreakage` contains additional information that we may want to display in the report (currently, a `date` field indicating when the crate will stop compiling). * A new variant `rustc_error::Level::Allow` is added. This is used when constructing a diagnostic for a future-breakage lint that is marked as allowed (via `#[allow]` or `--cap-lints`). This allows us to capture any future-breakage diagnostics in one place, while still discarding them before they are passed to the `Emitter`. * `DiagnosticId::Lint` is extended with a `has_future_breakage` field, indicating whether or not the `Lint` has future breakage information (and should therefore show up in the report). * `Session` is given access to the `LintStore` via a new `SessionLintStore` trait (since `librustc_session` cannot directly reference `LintStore` without a cyclic dependency). We use this to turn a string `DiagnosticId::Lint` back into a `Lint`, to retrieve the `FutureBreakage` data. Currently, `FutureBreakage.date` is always set to `None`. However, this could potentially be interpreted by Cargo in the future. I've enabled the future-breakage report for the `ARRAY_INTO_ITER` lint, which can be used to test out this PR. The intent is to use the field to allow Cargo to determine the date of future breakage (as described in [RFC 2834](https://github.com/rust-lang/rfcs/blob/master/text/2834-cargo-report-future-incompat.md)) without needing to parse the diagnostic itself. cc @pnkfelix
make exp_m1 and ln_1p examples more representative of use With this PR, the examples for `exp_m1` would fail if `x.exp() - 1.0` is used instead of `x.exp_m1()`, and the examples for `ln_1p` would fail if `(x + 1.0).ln()` is used instead of `x.ln_1p()`.

Use SOCK_CLOEXEC and accept4() on more platforms. This PR enables the use of `SOCK_CLOEXEC` and `accept4` on more platforms. ----- Android uses the linux kernel, so it should also support it.
