--- Comment #5 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- (In reply to Xi Ruoyao from comment #4) > IIRC the "signed_rep_t = __int128;" case has really detected a compiler bug, > so IMO we shouldn't just disable it. Maybe I should have been explicit: that was just for investigation purposes. > Maybe my memory is flawed though. Please link that PR here if you have it!
