This works just as you might expect - an 'extern const fn' is a 'const fn' that is callable from foreign code. Currently, panicking is not allowed in consts. When RFC 2345 is stabilized, then panicking in an 'extern const fn' will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime. Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary. This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well.
This commit improves the suggestions provided when function parameters do not have types: - A new suggestion is added for arbitrary self types, which suggests adding `self: ` before the type. - Existing suggestions are now provided when a `<` is found where a `:` was expected (previously only `,` and `)` or trait items), this gives suggestions in the case where the unnamed parameter type is generic in a free function. - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)` -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was found instead of `:`. - The ident will not be used for recovery when a `<` was found instead of `:`.

This fixes some test differences and also avoids overflow in issue-38591.rs.

…r=Centril Add support for `const unsafe? extern fn` This works just as you might expect - an `const extern fn` is a `const fn` that is callable from foreign code. Currently, panicking is not allowed in `const`s. When rust-lang/rfcs#2345 (rust-lang#51999) is stabilized, then panicking in an `const extern fn` will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime. Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary. This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well. Tracking issue: rust-lang#64926.
…p, r=Centril,estebank syntax: improve parameter without type suggestions Fixes rust-lang#64252. This PR improves the suggestions provided when function parameters do not have types: - A new suggestion is added for arbitrary self types, which suggests adding `self: ` before the type. - Existing suggestions are now provided when a `<` is found where a `:` was expected (previously only `,` and `)` or trait items), this gives suggestions in the case where the unnamed parameter type is generic in a free function. - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)` -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was found instead of `:`. - The ident will not be used for recovery when a `<` was found instead of `:`. r? @Centril cc @estebank @yoshuawuyts
Implement Clone::clone_from for LinkedList See rust-lang#28481. This represents a substantial speedup when the list sizes are comparable, and shouldn't ever be significantly worse. Technically split_off is doing an unnecessary search, but the code is hopefully cleaner as a result. I'm happy to rework anything that needs to be changed as well!
…houtboats BacktraceStatus: add Eq impl See discussion on rust-lang#53487. --- Is adding `Copy` too ambitious? It's a "status", so I don't forsee any non-POD data that might go in there, but it would restrict future variants more than `Eq` does. Cc: @withoutboats @abonander
