//@ needs-target-std
//@ ignore-wasm (explicit linker invocations)

// Passing linker arguments to the compiler used to be lost or reordered in a messy way
// as they were passed further to the linker. This was fixed in #70665, and this test
// checks that linker arguments remain intact and in the order they were originally passed in.
// See https://github.com/rust-lang/rust/pull/70665
