--- Comment #10 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
Just finished second bisect and reduce.  Came out to this commit as well.

  module brute_force
    integer, parameter :: r=3D9
     integer sudoku1(1, r)
    contains
  subroutine brute
  integer l(r), u(r)
     where(sudoku1(1, :) /=3D 1)
          l =3D 1
        u =3D 1
     end where
  do i1 =3D 1, u(1)
     do
        end do
     end do
  end
  end

gfortran -w -c exchange2.f90 -fprofile-generate -march=3Darmv8-a+sve -Ofast=

exchange2.f90.o

gives:

which is probably related to your last message.=
