async functions are disallowed (because `-> impl Trait` is not supported). `const` entry functions are allowed, nonsecure-call functions must be function pointers, which cannot be evaluated during constant evaluation.

epoll: do proper edge detection inside the epoll system
It has been removed 9 months ago, which is more than a few months.
bootstrap: Add snapshot tests for path-to-step handling This PR adds a suite of snapshot tests for how bootstrap translates command-line “paths” (which are not necessarily actual paths) into a set of top-level steps to execute. Unlike the existing suite of snapshot tests (for transitive step logging), I decided to use `.snap` files over inline snapshots, because I find that inline snapshots quickly make test files impossible to navigate. Instead, I set up a macro that makes it relatively easy to add or modify test cases. Using `.snap` files also means that the tests can be blessed by setting `INSTA_UPDATE=always`, without necessarily needing the `cargo insta` tool installed, though the tool can still be used instead if desired. These snapshot tests capture _current_ behavior, to prevent unintended changes or regressions. If the current behavior is wrong or undersirable, then any fix will necessarily have to re-bless the affected tests! r? Kobzol
Update git index before running diff-index Discussed in https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/tidy.3A.20strange.20number.20of.20modified.20files/with/553714742. This is apparently the cause of `x test tidy` printing weird number of formatted files, and also of sometimes quirky behavior of finding the files modified from a base commit.
…davidtwco cmse: add test for `async` and `const` functions tracking issue: rust-lang#81391 tracking issue: rust-lang#75835 Some additional tests that seemed useful while working on the RFC text. `async` functions are disallowed (because `-> impl Trait` is not supported). `const` entry functions are allowed, `nonsecure-call` does not make sense, because this abi can only be used on function pointers, which cannot be evaluated during constant evaluation. The async test is in the `c-variadic.rs` file because it has the minicore-compatible machinery for defining an async function. Splitting that logic out (like `minisimd.rs`) turns out to be complicated because the async stuff relies on types defined by minicore. r? ```@davidtwco```
…kingjubilee implement `feature(c_variadic_naked_functions)` tracking issue: rust-lang#148767 [#t-lang > C-variadic naked functions](https://rust-lang.zulipchat.com/#narrow/channel/213817-t-lang/topic/C-variadic.20naked.20functions/with/554593886) This feature allows naked c-variadic function definitions with any ABI that is supported for foreign c-variadic functions. ```rust #![feature(c_variadic, c_variadic_naked_functions)] #[unsafe(naked)] unsafe extern "win64" fn variadic_win64(_: u32, _: ...) -> u32 { core::arch::naked_asm!( r#" push rax mov qword ptr [rsp + 40], r9 mov qword ptr [rsp + 24], rdx mov qword ptr [rsp + 32], r8 lea rax, [rsp + 40] mov qword ptr [rsp], rax lea eax, [rdx + rcx] add eax, r8d pop rcx ret "#, ) } ``` r? ``@workingjubilee``

Remove more `#[must_use]` from portable-simd These lines were missed in <https://github.com/rust-lang/rust/commit/f3515fb127ae07f1b13340dde0c61a20291eb304>/rust-lang/rust#136923 because core_simd/src/masks/bitmask.rs is only conditionally compiled. https://github.com/rust-lang/rust/blob/25d319a0f656ee8faa7a534da299e76e96068a40/library/portable-simd/crates/core_simd/src/masks.rs#L9-L13 Removing them unblocks bootstrapping rustc in an environment where avx512f is enabled. Without this change: ```console error: `#[must_use]` attribute cannot be used on trait methods in impl blocks --> library/core/src/../../portable-simd/crates/core_simd/src/masks/bitmask.rs:173:5 | 173 | #[must_use = "method returns a new mask and does not mutate the original value"] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release! = help: `#[must_use]` can be applied to data types, functions, unions, required trait methods, provided trait methods, inherent methods, foreign functions, and traits = note: `-D unused-attributes` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(unused_attributes)]` ``` To reproduce: `RUSTC_BOOTSTRAP=1 RUSTFLAGS=-Ctarget-feature=+avx512f cargo +nightly check --manifest-path=library/portable-simd/crates/core_simd/Cargo.toml --target=x86_64-unknown-linux-gnu --no-default-features`
