user-defined type conversions, issue list of ambiguites in addition to the diagnostic. So, clang now issues the following: b.cpp:19:19: error: left hand operand to ->* must be a pointer to class compatible with the right hand operand, but is 'struct C1' int i = c1->*pmf; ~~^ b.cpp:19:19: note: because of ambiguity in conversion of 'struct C1' to 'struct E *' b.cpp:5:5: note: candidate function operator E*(); ^ b.cpp:11:5: note: candidate function operator E*(); ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83862 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-11Test exception spec compatibility on return type and parameters.Sebastian Redl
Along the way, use RequireCompleteType when testing exception spec types. Separate all the ugly spec stuff into its own file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83764 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-10Implement the core checking for compatible exception specifications in ↵Sebastian Redl
assignment and initialization. The exception specification of the assignee must be the same or a subset of the target. In addition, exception specifications on arguments and return types must be equivalent, but this is not implemented yet. This currently produces two diagnostics for every invalid assignment/initialization, due to the diagnostic produced outside PerformImplicitConversion, e.g. in CheckSingleInitializer. I don't know how to suppress this; in any case I think it is the wrong place for a diagnostic, since there are other diagnostics produced inside the function. So I'm leaving it as it is for the moment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83710 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09Minor tweaks for code-completion:Douglas Gregor
- Filter out unnamed declarations - Filter out declarations whose names are reserved for the implementation (e.g., __bar, _Foo) - Place OVERLOAD: or COMPLETION: at the beginning of each code-completion result, so we can easily separate them from other compilation results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83680 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09When declaring a friend class template, we may end up finding anDouglas 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
