Hi @probinson @dblaikie  @aprantl , I've was investigating and working on your inputs regarding the problem with DW_at_defaulted once. I think clang has also some issues. Though I'm not able to precisely point out. I ranned into some problems in CFE while marking out_of_class functions. i.e consider this for instance "debug-info-defaulted-out_of_class.cpp" FIXME:.  Causing too much trouble and possibly can introduce some bugs in clang/llvm. 
May be we'll reconsider this in future. Thanks for putting time in reviewing and discussing this.

Anyway here's the next course of action I'm considering. I'll be marking this review as abandoned. I'll raise a fresh new review for DW_AT_deleted feature, that;s pretty straight forward, considering C++ spec. If it's deleted, it has to be declared/defined{whatever} deleted in it's first declaration. This feature also augments the consumer information regarding which spl member functions are deleted, hence restrict their calling for user or do something useful with this at it's disposal.

@probinson @dblaikie @aprantl Please share your thoughts/comments inclination regarding adding this DW_AT_deleted to clang/llvm.
