// This test case makes sure that native libraries are linked with appropriate semantics
// when the `[+-]bundle,[+-]whole-archive` modifiers are applied to them.
// The test works by checking that the resulting executables produce the expected output,
// part of which is emitted by otherwise unreferenced C code. If +whole-archive didn't work
// that code would never make it into the final executable and we'd thus be missing some
// of the output.
// See https://github.com/rust-lang/rust/issues/88085
//@ ignore-cross-compile
// Reason: compiling C++ code does not work well when cross-compiling
// plus, the compiled binary is executed
