// `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 is a sanity check for this feature, done by comparing its output against expected
// output.
// See https://github.com/rust-lang/rust/pull/89025
//@ only-windows
use run_make_support::{cc, diff, extra_c_flags, is_windows_msvc, run, rustc};
// NOTE: build_native_dynamic lib is not used, as the special `def` files
// must be passed to the CC compiler.
