// `raw-dylib` is a Windows-specific attribute which emits idata sections for the items in the | ||
// attached extern block, | ||
// so they may be linked against without linking against an import library. | ||
// To learn more, read https://github.com/rust-lang/rfcs/blob/master/text/2627-raw-dylib-kind.md | ||
// `#[link_ordinal(n)]` allows Rust to link against DLLs that export symbols by ordinal rather | ||
// than by name. As long as the ordinal matches, the name of the function in Rust is not | ||
// required to match the name of the corresponding function in the exporting DLL. | ||
// This test checks the correctness of this feature by comparing its output against expected | ||
// output. | ||
// See https://github.com/rust-lang/rust/pull/89025 | ||
