bors 4f1be92153 Auto merge of #129753 - folkertdev:stabilize-const-extern-fn, r=RalfJung ... stabilize `const_extern_fn` closes https://github.com/rust-lang/rust/issues/64926 tracking issue: https://github.com/rust-lang/rust/issues/64926 reference PR: https://github.com/rust-lang/reference/pull/1596 ## Stabilizaton Report ### Summary Using `const extern "Rust"` and `const extern "C"` was already stabilized (since version 1.62.0, see https://github.com/rust-lang/rust/pull/95346). This PR stabilizes the other calling conventions: it is now possible to write `const unsafe extern "calling-convention" fn` and `const extern "calling-convention" fn` for any supported calling convention: ```rust const extern "C-unwind" fn foo1(val: u8) -> u8 { val + 1} const extern "stdcall" fn foo2(val: u8) -> u8 { val + 1} const unsafe extern "C-unwind" fn bar1(val: bool) -> bool { !val } const unsafe extern "stdcall" fn bar2(val: bool) -> bool { !val } ``` This can be used to const-ify an `extern fn`, or conversely, to make a `const fn` callable from external code. r?
