[libc++] Fix and document visibility attributes for Clang, GCC and Windows.
Summary: This patch fixes a number of problems with the visibility macros across GCC (on Unix) and Windows (DLL import/export semantics). All of the visibility macros are now documented under `DesignDocs/VisibilityMacros.rst`. Now I'll no longer forget the subtleties of each! This patch adds two new visibility macros: * `_LIBCPP_ENUM_VIS` for controlling the typeinfo of enum types. Only Clang supports this. * `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` for redefining visibility on explicit instantiation declarations. Clang and Windows require this. After applying this patch GCC only emits one -Wattribute warning opposed to 30+.

Overview
|
||||
========
|
||||
|
||||
Libc++ uses various "visibility" macros in order to provide a stable ABI in
|
||||
both the library and the headers. These macros work by changing the
|
||||
visibility and inlining characteristics of the symbols they are applied to.
|
||||
|
||||
Visibility Macros
|
||||
=================
|
||||
|
||||
**_LIBCPP_HIDDEN**
|
||||
Mark a symbol as hidden so it will not be exported from shared libraries.
|
||||
|
||||
**_LIBCPP_FUNC_VIS**
|
||||
Mark a symbol as being exported by the libc++ library. This attribute must
|
||||
be applied to the declaration of all functions exported by the libc++ dylib.
|
||||
|
||||
**_LIBCPP_INLINE_VISIBILITY**
|
||||
Mark a function as hidden and force inlining whenever possible.
|
||||
|
||||
**_LIBCPP_ALWAYS_INLINE**
|
||||
A synonym for `_LIBCPP_INLINE_VISIBILITY`
|
||||
|
||||
**_LIBCPP_TYPE_VIS**
|
||||
Mark a type's typeinfo and vtable as having default visibility.
|
||||
`_LIBCPP_TYPE_VIS`. This macro has no effect on the visibility of the
|
||||
type's member functions. This attribute cannot be used on class templates.
|
||||
|
||||
**GCC Behavior**: GCC does not support Clang's `type_visibility(...)`
|
||||
attribute. With GCC the `visibility(...)` attribute is used and member
|
||||
functions are affected.
|
||||
|
||||
**_LIBCPP_TYPE_VIS_ONLY**
|
||||
The same as `_LIBCPP_TYPE_VIS` except that it may be applied to templates.
|
||||
|
||||
**Windows Behavior**: DLLs do not support dllimport/export on class templates.
|
||||
The macro has an empty definition on this platform.
|
||||
|
||||
Note: This macro should be renamed `_LIBCPP_TEMPLATE_TYPE_VIS`.
|
||||
|
||||
**_LIBCPP_ENUM_VIS**
|
||||
Mark the typeinfo of an enum as having default visibility. This attribute
|
||||
should be applied to all enum declarations.
|
||||
|
||||
**Windows Behavior**: DLLs do not support importing or exporting enumeration
|
||||
typeinfo. The macro has an empty definition on this platform.
|
||||
|
||||
**GCC Behavior**: GCC un-hides the typeinfo for enumerations by default, even
|
||||
if `-fvisibility=hidden` is specified. Additionally applying a visibility
|
||||
attribute to an enum class results in a warning. The macro has an empty
|
||||
definition with GCC.
|
||||
|
||||
**_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS**
|
||||
Mark the member functions, typeinfo, and vtable of the type named in
|
||||
a `_LIBCPP_EXTERN_TEMPLATE` declaration as being exported by the libc++ library.
|
||||
This attribute must be specified on all extern class template declarations.
|
||||
|
||||
This macro is used to override the `_LIBCPP_TYPE_VIS_ONLY` attribute
|
||||
specified on the primary template and to export the member functions produced
|
||||
by the explicit instantiation in the dylib.
|
||||
|
||||
**GCC Behavior**: GCC ignores visibility attributes applied the type in
|
||||
extern template declarations and applying an attribute results in a warning.
|
||||
However since `_LIBCPP_TYPE_VIS_ONLY` is the same as `_LIBCPP_TYPE_VIS` the
|
||||
visibility is already correct. The macro has an empty definition with GCC.
|
||||
|
||||
**_LIBCPP_EXCEPTION_ABI**
|
||||
Mark the member functions, typeinfo, and vtable of the type as being exported
|
||||
by the libc++ library. This macro must be applied to all *exception types*.
|
||||
Exception types must be defined directly in namespace `std` and not the
|
||||
versioning namespace.
