++============ ++ ++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 a <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 has never 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. ++ ++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; for functions also 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 active tag, as it is ++required from the return type `std::string` but not available. +Index: include/clang/Basic/Attr.td +=================================================================== +--- include/clang/Basic/Attr.td ++++ include/clang/Basic/Attr.td +@@ -349,6 +349,14 @@ + // Attributes begin here + // + ++def AbiTag : Attr { ++ let Spellings = [GCC<"abi_tag">]; ++ let Args = [VariadicStringArgument<"Tags">]; ++ let Subjects = SubjectList<[Struct, Var, Function, Namespace], ErrorDiag, ++ "ExpectedStructClassVariableFunctionMethodOrInlineNamespace">; ++ let Documentation = [Undocumented]; ++} ++ + def AddressSpace : TypeAttr { + let Spellings = [GNU<"address_space">]; + let Args = [IntArgument<"AddressSpace">]; +Index: include/clang/Basic/DiagnosticSemaKinds.td +=================================================================== +--- include/clang/Basic/DiagnosticSemaKinds.td ++++ include/clang/Basic/DiagnosticSemaKinds.td +@@ -2434,7 +2434,8 @@ + "Objective-C instance methods|init methods of interface or class extension declarations|" + "variables, functions and classes|Objective-C protocols|" + "functions and global variables|structs, unions, and typedefs|structs and typedefs|" +- "interface or protocol declarations|kernel functions}1">, ++ "interface or protocol declarations|kernel functions|" ++ "structs, classes, variables, functions, methods and inline namespaces}1">, + InGroup<IgnoredAttributes>; + def err_attribute_wrong_decl_type : Error<warn_attribute_wrong_decl_type.Text>; + def warn_type_attribute_wrong_type : Warning< +@@ -4144,6 +4145,15 @@ + def err_redefinition_extern_inline : Error< + "redefinition of a 'extern inline' function %0 is not supported in " + "%select{C99 mode|C++}1">; ++def err_attr_abi_tag_only_on_inline_namespace : ++ Error<"abi_tag attribute only allowed on inline namespaces">; ++def err_attr_abi_tag_only_on_named_namespace : ++ Error<"abi_tag attribute only allowed on named namespaces">; ++def err_abi_tag_on_redeclaration : ++ Error<"cannot add abi_tag attribute in redeclaration">; ++def err_new_abi_tag_on_redeclaration : ++ Error<"abi_tag %0 missing in original declaration">; ++ + + def note_deleted_dtor_no_operator_delete : Note< + "virtual destructor requires an unambiguous, accessible 'operator delete'">; +Index: include/clang/Sema/AttributeList.h +=================================================================== +--- include/clang/Sema/AttributeList.h ++++ include/clang/Sema/AttributeList.h +@@ -855,7 +855,8 @@ + ExpectedStructOrUnionOrTypedef, + ExpectedStructOrTypedef, + ExpectedObjectiveCInterfaceOrProtocol, +- ExpectedKernelFunction ++ ExpectedKernelFunction, ++ ExpectedStructClassVariableFunctionMethodOrInlineNamespace + }; + + } // end namespace clang +Index: lib/AST/ItaniumMangle.cpp +=================================================================== +--- lib/AST/ItaniumMangle.cpp ++++ lib/AST/ItaniumMangle.cpp +@@ -31,6 +31,7 @@ + #include "llvm/ADT/StringExtras.h" + #include "llvm/Support/ErrorHandling.h" + #include "llvm/Support/raw_ostream.h" ++#include <set> + + #define MANGLE_CHECKER 0 + +@@ -212,6 +212,8 @@ + class CXXNameMangler { + ItaniumMangleContextImpl &Context; + raw_ostream &Out; ++ bool NullOut = false; ++ bool DisableDerivedAbiTags = false; + + /// The "structor" is the top-level declaration being mangled, if + /// that's not a template specialization; otherwise it's the pattern +@@ -261,6 +263,167 @@ + + } FunctionTypeDepth; + ++ // abi_tag is a gcc attribute, taking one or more strings called "tags". ++ // ++ // the goal is to annotage against which version of a library an object was ++ // build and to be able to provide backwards compatibility ("dual abi"). ++ // ++ // for this the emitted mangled names have to be different, while you don't ++ // want the user to have to use different names in the source. ++ // ++ // the abi_tag can be present on Struct, Var and Function declarations as ++ // "explicit" tag, and on inline Namespace as "implicit" tag.
