// `-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, leaf).
|
||
|
|
// See https://github.com/rust-lang/rust/pull/88354

// Reason: branch protection is not supported on other architectures
|

//@ ignore-cross-compile

// Reason: the compiled binary is executed
