// This is a non-regression test for issue #81408 involving an lld bug and ThinLTO, on windows.
// MSVC's link.exe doesn't need any workarounds in rustc, but lld does, so we'll check that the
// binary runs successfully instead of using a codegen test.
//@ only-x86_64-pc-windows-msvc
//@ needs-rust-lld
//@ ignore-cross-compile: the built binary is executed
