--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Thorsten Glaser from comment #2) > Sure? bug 110934 was about =all and using =used fixed the ICE back then. Now > it ICEs in both. Yes it is a dup because it is about the FP registers in the reduced testcase there is a double type which is used and =used will ICE due to the FP register being used and needing to be zero'ed.
