The relative vtable ABI (PR26723) needs PLT relocations to refer to virtual functions defined in other DSOs. The unnamed_addr attribute means that the function's address is not significant, so we're allowed to substitute it with the address of a PLT entry. Also includes a bonus feature: addends for COFF image-relative references. Differential Revision: http://reviews.llvm.org/D17938 llvm-svn: 267211
