Previous patches added support for dumping global variables of primitive types, so we now do the same for class types. For the most part, everything just worked, there was only one minor bug needing fixed, which was that for variables of modified types (e.g. const, volatile, etc) we can't resolve the forward decl in CreateAndCacheType because the PdbSymUid must point to the LF_MODIFIER which must point to the forward decl. So when it comes time to call CompleteType, an assert was firing because we expected to get a class, struct, union, or enum, but we were getting an LF_MODIFIER instead. The other issue is that one the newly added tests is for an array member, which was not yet supported, so we add support for that now in this patch. There's probably room for other interesting layout test cases here, but this at least should test the basics. Differential Revision: https://reviews.llvm.org/D53822 llvm-svn: 345629
