--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> --- https://gcc.opensuse.org/gcc-old/c++bench-czerny/pb11/pb11-summary.txt-2-0.html runs with -Ofast -funroll-loops so indeed does not seem essential to trigger the regression (it may be two different ones of course) note that also tfft,aermod and tfft2 shows regression that may be easy to track/fix.
