RFC: A new ABI for virtual calls, and a change to the virtual call representation in the IR
...relative relocation that refers directly to the symbol if defined within the current module, or to a PLT entry if not. This is the same type of relocation that is needed to implement relative branches on x86, so I'd expect it to be generally available on that architecture (ELF has R_{386,X86_64}_PLT32, Mach-O has X86_64_RELOC_BRANCH, COFF has IMAGE_REL_{AMD64,I386}_REL32, which may resolve to a thunk [1], which is essentially the same thing as a PLT entry). It is also present on ARM (R_ARM_PREL31, which was apparently added to support unwind tables). > > We still need some way to create P...

RFC: A new ABI for virtual calls, and a change to the virtual call representation in the IR
Hi all, I'd like to make a proposal to implement the new vtable ABI described in PR26723, which I'll call the relative ABI. That bug gives more details and justification for that ABI. The user interface for the new ABI would be that -fwhole-program-vtables would take an optional value indicating which aspects of the program have whole-program scope. For example, the existing
