// Setting the GCC -fvisibility=hidden command line option is not quite the same
|
|
// as setting the pragma below: the former only affects definitions, whereas the
|
|
// pragma affects extern declarations as well. So if we want to ensure that no
|
|
// GOT indirected symbol references are emitted, we need to use the pragma, or
|
|
// GOT based cross object references could be emitted, e.g., in libraries, and
|
|
// these cannot be relaxed to ordinary symbol references at link time.
