// The unstable flag `-Z export-executable-symbols` exports symbols from executables, as if
// they were dynamic libraries. This test is a simple smoke test to check that this feature
// works by using it in compilation, then checking that the output binary contains the exported
// symbol.
// See https://github.com/rust-lang/rust/pull/85673

//@ only-unix
// Reason: the export-executable-symbols flag only works on Unix
// due to hardcoded platform-specific implementation
// (See #85673)
//@ ignore-wasm32
//@ ignore-wasm64
//@ ignore-none
// Reason: no-std is not supported
