Maybe immediately after the call to init_adjust_machine_modes from do_compile? (It can't actually be inside backend_init, since it needs to happen even if just preprocessing - whether __SIZEOF_INT128__ gets defined depends on __int128 availability, and presumably you'll have such __SIZEOF_INT<N>__ macros for whichever such types are available - in which case no_backend is true.) -- Joseph S.
