2009-05-14In C++, warn when something previously declared as a "struct" is laterDouglas Gregor
declared as a "class", or vice-versa. This warning is under the control of -Wmismatched-tags, which is off by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71773 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-14Implement explicit instantiations of member classes of class templates, e.g.,Douglas Gregor
template<typename T> struct X { struct Inner; }; template struct X<int>::Inner; This change is larger than it looks because it also fixes some a problem with nested-name-specifiers and tags. We weren't requiring the DeclContext associated with the scope specifier of a tag to be complete. Therefore, when looking for something like "struct X<int>::Inner", we weren't instantiating X<int>. This, naturally, uncovered a problem with member pointers, where we were requiring the left-hand side of a member pointer access expression (e.g., x->*) to be a complete type. However, this is wrong: the semantics of this expression does not require a complete type (EDG agrees). Stuart vouched for me. Blame him. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71756 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-13Add some basic type checking for attributes ns_returns_retained andTed Kremenek
cf_returns_retained. Currently this attribute can now be applied to any Objective-C method or C function that returns a pointer or Objective-C object type. Modify the tablegen definition of diagnostic 'warn_attribute_wrong_decl_type' to expect that the diagnostics infrastructure will add quotes around the attribute name when appropriate. Alonq with this change, I modified the places where this warning is issued to passed the attribute's IdentifierInfo* instead of having a hard-coded C constant string. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71718 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-13ABI handling: Fix invalid assertion, it is possible for a validDaniel Dunbar
coercion to be specified which truncates padding bits. It would be nice to still have the assert, but we don't have any API call for the unpadding size of a type yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71695 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Improve the semantic checking for explicit instantiations ofDouglas Gregor
templates. In particular: - An explicit instantiation can follow an implicit instantiation (we were improperly diagnosing this as an error, previously). - In C++0x, an explicit instantiation that follows an explicit specialization of the same template specialization is ignored. In C++98, we just emit an extension warning. - In C++0x, an explicit instantiation must be in a namespace enclosing the original template. C++98 has no such requirement. Also, fixed a longstanding FIXME regarding the integral type that is used for the size of a constant array type when it is being instantiated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71689 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-13Fix rdar://6881069, a crash on a form of vector_size that weChris Lattner
don't support. While it would be nice to support this eventually, this form is not common at all (just seen in gcc testsuite) and it might be better to model vector_size as a type attribute anyway. For now just emit a nice error on it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71633 91177308-0d34-0410-b5e6-96231b3b80d8

parse just a single declaration and provide a reasonable diagnostic when the "only one declarator per template declaration" rule is violated.
