------- Comment #2 from rguenth at gcc dot gnu dot org  2008-04-22 15:22 -------
Bwaves from SPEC2006 has

...
               do l=1,nb
                  y(l,i,j,k)=0.0d0
                  do m=1,nb
                     y(l,i,j,k)=y(l,i,j,k)+
     1               a(l,m,i,j,k)*x(m,i,j,k)+
     2               axp(l,m,i,j,k)*x(m,ip1,j,k)+
     3               ayp(l,m,i,j,k)*x(m,i,jp1,k)+
     4               azp(l,m,i,j,k)*x(m,i,j,kp1)+
     5               axm(l,m,i,j,k)*x(m,im1,j,k)+
     6               aym(l,m,i,j,k)*x(m,i,jm1,k)+
     7               azm(l,m,i,j,k)*x(m,i,j,km1)
                  enddo
               enddo

which we don't distribute either (even with PRE/lim turned off).
