2010-02-13Switch the standard DeclarationName comparator to be a tri-valued comparator.John McCall
Use that while fixing a nasty misuse of qsort in vtable codegen which, somehow, has not actually caused a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96062 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11Use getAs instead of cast/dyn_cast on types. (I'm sure Doug will appreciate ↵Anders Carlsson
this). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95911 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95874 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Check in the beginnings of my new vtable layout builder idea.Anders Carlsson
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code. I've also added a very simple new vtable layout test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95865 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-05Make use of available_externally linkage for vtables when theDouglas Gregor
non-inline key function of a class template instantiation, when no key function is present, the class template instantiation itself was instantiated with an explicit instantiation declaration (aka extern template). I'm fairly certain that the C++0x specification gives us this lattitude, although GCC doesn't take advantage of it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92779 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-05Improve key-function computation for templates. In particular:Douglas Gregor
- All classes can have a key function; templates don't change that. non-template classes when computing the key function. - We always mark all of the virtual member functions of class template instantiations. - The vtable for an instantiation of a class template has weak linkage. We could probably use available_externally linkage for vtables of classes instantiated by explicit instantiation declarations (extern templates), but GCC doesn't do this and I'm not 100% that the ABI permits it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92753 91177308-0d34-0410-b5e6-96231b3b80d8
