// `-Z branch protection` is an unstable compiler feature which adds pointer-authentication
// code (PAC), a useful hashing measure for verifying that pointers have not been modified.
// This test checks that compilation and execution is successful when this feature is activated,
// with some of its possible extra arguments (bti, pac-ret, pc, leaf, b-key).
// See https://github.com/rust-lang/rust/pull/88354
//@ only-aarch64
// Reason: branch protection is not supported on other architectures
//@ ignore-cross-compile
// Reason: the compiled binary is executed
