This function attribute enables you to specify multiple aliases for functions.
Where a function is defined in the current translation unit, the alias call is replaced by a call to the function, and the alias is emitted alongside the original name. Where a function is not defined in the current translation unit, the alias call is replaced by a call to the real function.
