--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I'm really surprised we never added no symbols in particular symver in the past on some arch. But, sure, #ifdefing out the whole thing is fine if the abi checking is able to cope with this, and if we in the end make sure that when we add CXXABI_1.3.17 symver on all arches that it will conditionally inherit either from CXXABI_1.3.16 (on riscv) or CXXABI_1.3.15 (elsewhere).
