2009-10-08Add more testing for the properties of explicit specialization. Douglas Gregor
Also, eliminate a redundant diagnostic by marking a variable declared with incomplete type as an invalid declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83553 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-08Don't complain about out-of-line explicit specializations of memberDouglas Gregor
function and member function templates that are not definitions. Add more tests to ensure that explicit specializations of member function templates prevent instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83550 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-08Improve checking for specializations of member classes of classDouglas Gregor
templates, and keep track of how those member classes were instantiated or specialized. Make sure that we don't try to instantiate an explicitly-specialized member class of a class template, when that explicit specialization was a declaration rather than a definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83547 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-08For instantiations of static data members of class templates, keepDouglas Gregor
track of the kind of specialization or instantiation. Also, check the scope of the specialization and ensure that a specialization declaration without an initializer is not a definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83533 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-08Make sure to set the template specialization kind of an explicitDouglas Gregor

2009-10-08Only perform an implicit instantiation of a function if its templateDouglas Gregor
specialization kind is TSK_ImplicitInstantiation. Previously, we would end up implicitly instantiating functions that had explicit specialization declarations or explicit instantiation declarations (with no corresponding definitions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83511 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-07Keep track of whether a member function instantiated from a memberDouglas Gregor
function of a class template was implicitly instantiated, explicitly instantiated (declaration or definition), or explicitly specialized. The same MemberSpecializationInfo structure will be used for static data members and member classes as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83509 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-07Refactor checking of the scope of explicit template specializationDouglas Gregor
declarations and explicit template instantiations, improving diagnostics and making the code usable for function template specializations (as well as class template specializations and partial specializations). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83436 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Patch to implement C++ [over.built]p11 of overload resolution.Fariborz Jahanian
Doug, please review. There is a FIXME in the test case with a question which is unrelated to this patch (that is, error is issued before set of builtins are added to the candidate list). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83429 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Test explicit specialization for all of the various cases whereDouglas Gregor
explicit specializations can occur. Also, fix a minor recovery bug where we should allow declarations coming from the parser to be NULL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83416 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Refactor the code that walks a C++ inheritance hierarchy, searchingDouglas Gregor
for bases, members, overridden virtual methods, etc. The operations isDerivedFrom and lookupInBases are now provided by CXXRecordDecl, rather than by Sema, so that CodeGen and other clients can use them directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83396 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Refixed pr5086 by letting Expr::isNullPointerConstantFariborz Jahanian
handle checking for a null pointer for a zero-valued enumerator; moving the test case from CodeGen to Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83350 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-05tweaked my last patch to 1) preserve the protocol inFariborz Jahanian
extension class's protocol list so its AST is complete. 2) Because of this no need to issue warning on unimplemeted methods coming from the extended class protocols because warning is issued when class definition is seen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83326 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-01Make sure to free the explicit template arguments provided for anDouglas Gregor
explicit instantiation. Also, tighten up reference-count checking to help catch these issues earlier. Fixes PR5069. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83225 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-01- Remove Sema::FindMethodInNestedImplementations().Steve Naroff
- Add ObjCInterfaceDecl::lookupPrivateInstanceMethod(). - Convert clients. No functionality change - One less method in Sema:-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83224 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-01When the return type of a function is dependent, don't perform anyDouglas Gregor
of the flow-control checks for falling off the end of a function, since the return type may instantiate to void. Similarly, if a return statement has an expression and the return type of the function is void, don't complain if the expression is type-dependent, since that type could instantiate to void. Fixes PR5071. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83222 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-01Anonymous namespaces, sema + codegen. A lot of semantics are still broken,John McCall
apparently because using directives aren't quite working correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83184 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-30Improve template argument deduction in the case where the parameterDouglas Gregor
type is a template-id (e.g., basic_ostream<CharT, Traits>) and the argument type is a class that has a derived class matching the parameter type. Previously, we were giving up on template argument deduction too early. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83177 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-30When overload resolution fails for an overloaded operator, show theDouglas Gregor
overload candidates (but not the built-in ones). We still rely on the underlying built-in semantic analysis to produce the initial diagnostic, then print the candidates following that diagnostic. One side advantage of this approach is that we can perform more validation of C++'s operator overloading with built-in candidates vs. the semantic analysis for those built-in operators: when there are no viable candidates, we know to expect an error from the built-in operator handling code. Otherwise, we are not modeling the built-in semantics properly within operator overloading. This is checked as: assert(Result.isInvalid() && "C++ binary operator overloading is missing candidates!"); if (Result.isInvalid()) PrintOverloadCandidates(CandidateSet, /*OnlyViable=*/false); The assert() catches cases where we're wrong in a +Asserts build. The "if" makes sure that, if this happens in a production clang (-Asserts), we still build the proper built-in operator and continue on our merry way. This is effectively what happened before this change, but we've added the assert() to catch more flies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83175 91177308-0d34-0410-b5e6-96231b3b80d8

concrete types. Use unqualified desugaring for getAs<> and sundry. Fix a few users to either not desugar or use qualified desugar, as seemed appropriate. Removed Type's qualified desugar method, as it was easy to accidentally use instead of QualType's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83116 91177308-0d34-0410-b5e6-96231b3b80d8
