-+ABI tags
-+========
-+
-+Introduction
-+============
-+
-+This text tries to describe gcc semantic for mangling "abi_tag" attributes
-+described in https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html
-+
-+There is no guarantee the following rules are correct, complete or make sense
-+in any way as they were determined empirically by experiments with gcc5.
-+
-+Declaration
-+===========
-+
-+ABI tags are declared in an abi_tag attribute and can be applied to a
-+function, variable, class or inline namespace declaration. The attribute takes
-+one or more strings (called tags); the order does not matter.
-+
-+See https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html for
-+details.
-+
-+Tags on an inline namespace are called "implicit tags", all other tags are
-+"explicit tags".
-+
-+Mangling
-+========
-+
-+All tags that are "active" on an <unqualified-name> are emitted after the
-+<unqualified-name>, before <template-args> or <discriminator>, and are part of
-+the same <substitution> the <unqualified-name> is.
-+
-+They are mangled as:
-+
-+ <abi-tags> ::= <abi-tag>* # sort by name
-+ <abi-tag> ::= B <tag source-name>
-+
-+Example:
-+
-+ __attribute__((abi_tag("test")))
-+ void Func();
-+
-+ gets mangled as: _Z4FuncB4testv (prettified as `Func[abi:test]()`)
-+
-+Active tags
-+===========
-+
-+A namespace does not have any active tags. For types (class / struct / union /
-+enum), the explicit tags are the active tags.
-+
-+For variables and functions, the active tags are the explicit tags plus any
-+"required tags" which are not in the "available tags" set:
-+
-+ derived-tags := (required-tags - available-tags)
-+ active-tags := explicit-tags + derived-tags
-+
-+Required tags for a function
-+============================
-+
-+If a function is used as a local scope for another name, and is part of
-+another function as local scope, it doesn't have any required tags.
-+
-+If a function is used as a local scope for a guard variable name, it doesn't
-+have any required tags.
-+
-+Otherwise the function requires any implicit or explicit tag used in the name
-+for the return type.
-+
-+Example:
-+ namespace A {
-+ inline namespace B __attribute__((abi_tag)) {
-+ struct C { int x; };
-+ }
-+ }
-+
-+ A::C foo();
-+
-+ gets mangled as: _Z3fooB1Bv (prettified as `foo[abi:B]()`)
-+
-+Required tags for a variable
-+============================
-+
-+A variable requires any implicit or explicit tag used in its type.
-+
-+Available tags
-+==============
-+
-+All tags used in the prefix and in the template arguments for a name are
-+available. Also, for functions, all tags from the <bare-function-type>
-+(which might include the return type for template functions) are available.
-+
-+For <local-name>s all active tags used in the local part (<function-
-+encoding>) are available, but not implicit tags which were not active.
-+
-+Implicit and explicit tags used in the <unqualified-name> for a function (as
-+in the type of a cast operator) are NOT available.
-+
-+Example: a cast operator to std::string (which is
-+std::__cxx11::basic_string<...>) will use 'cxx11' as an active tag, as it is
-+required from the return type `std::string` but not available.

-+The ``abi_tag`` attribute can be applied to a function, variable, class or
-+inline namespace declaration to modify the mangled name of the entity. It gives
-+the ability to distinguish between different versions of the same entity but
-+with different ABI versions supported. For example, a newer version of a class
-+could have a different set of data members and thus have a different size. Using
-+the ``abi_tag`` attribute, it is possible to have different mangled names for
-+a global variable of the class type. Therefor, the old code could keep using
-+the old manged name and the new code will use the new mangled name with tags.
