P1787R6 changes wording of [dcl.pre]/9. Quote from the current draft ([[dcl.pre]/5](https://eel.is/c++draft/dcl.pre#5)): > If a [declarator-id](https://eel.is/c++draft/dcl.decl.general#nt:declarator-id) is a name, the [init-declarator](https://eel.is/c++draft/dcl.decl.general#nt:init-declarator) and (hence) the declaration introduce that name[.](https://eel.is/c++draft/dcl.pre#5.sentence-1) > [Note [3](https://eel.is/c++draft/dcl.pre#note-3): Otherwise, the [declarator-id](https://eel.is/c++draft/dcl.decl.general#nt:declarator-id) is a [qualified-id](https://eel.is/c++draft/expr.prim.id.qual#nt:qualified-id) or names a destructor or its [unqualified-id](https://eel.is/c++draft/expr.prim.id.unqual#nt:unqualified-id) is a [template-id](https://eel.is/c++draft/temp.names#nt:template-id) and no name is introduced[.](https://eel.is/c++draft/dcl.pre#5.sentence-2) — end note] Added: Modified: clang/test/CXX/drs/cwg18xx.cpp clang/www/cxx_dr_status.html Removed: ################################################################################ diff --git a/clang/test/CXX/drs/cwg18xx.cpp b/clang/test/CXX/drs/cwg18xx.cpp index 3a2248a1af551..ea322ff4c8be1 100644 --- a/clang/test/CXX/drs/cwg18xx.cpp +++ b/clang/test/CXX/drs/cwg18xx.cpp @@ -222,6 +222,53 @@ namespace cwg1815 { // cwg1815: no #endif } +namespace cwg1820 { // cwg1820: 3.5 +typedef int A; +typedef int cwg1820::A; +// expected-warning@-1 {{extra qualification on member 'A'}} +// expected-error@-2 {{typedef declarator cannot be qualified}} + +namespace B { +typedef int cwg1820::A; +// expected-error@-1 {{cannot define or redeclare 'A' here because namespace 'B' does not enclose namespace 'cwg1820'}} +// expected-error@-2 {{typedef declarator cannot be qualified}} +} + +class C1 { + typedef int cwg1820::A; + // expected-error@-1 {{non-friend class member 'A' cannot have a qualified name}} + // expected-error@-2 {{typedef declarator cannot be qualified}} +}; + +template <typename> +class C2 { + typedef int cwg1820::A; + // expected-error@-1 {{non-friend class member 'A' cannot have a qualified name}} + // expected-error@-2 {{typedef declarator cannot be qualified}} +}; + +void d1() { + typedef int cwg1820::A; + // expected-error@-1 {{definition or redeclaration of 'A' not allowed inside a function}} + // expected-error@-2 {{typedef declarator cannot be qualified}} +} + +template<typename> +void d2() { + typedef int cwg1820::A; + // expected-error@-1 {{definition or redeclaration of 'A' not allowed inside a function}} + // expected-error@-2 {{typedef declarator cannot be qualified}} +} + +#if __cplusplus >= 201103L +auto e = [] { + typedef int cwg1820::A; + // expected-error@-1 {{definition or redeclaration of 'A' not allowed inside a function}} + // expected-error@-2 {{typedef declarator cannot be qualified}} +}; +#endif +} // namespace cwg1820 + namespace cwg1821 { // cwg1821: 2.9 struct A { template <typename> struct B { diff --git a/clang/www/cxx_dr_status.html b/clang/www/cxx_dr_status.html index 992dc61d65e42..12ab59224e82e 100755 --- a/clang/www/cxx_dr_status.html +++ b/clang/www/cxx_dr_status.html @@ -10728,7 +10728,7 @@ <h2 id="cxxdr">C++ defect report implementation status</h2> <td><a href="https://cplusplus.github.io/CWG/issues/1820.html";>1820</a></td> <td>CD6</td> <td>Qualified typedef names</td> - <td class="unknown" align="center">Unknown</td> + <td class="full" align="center">Clang 3.5</td> </tr> <tr id="1821"> <td><a href="https://cplusplus.github.io/CWG/issues/1821.html";>1821</a></td> _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
