#### 5.50.10 Visibility Pragmas

`#pragma GCC visibility push(`visibility`)`
`#pragma GCC visibility pop`
  This pragma allows the user to set the visibility for multiple declarations without having to give each a visibility attribute See Function Attributes, for more information about visibility and the attribute syntax.

  In C++, ‘`#pragma GCC visibility`’ affects only namespace-scope declarations. Class members and template specializations are not affected; if you want to override the visibility for a particular member or instantiation, you must use an attribute.
