This is still true, you need still need -fno-tree-pre -fno-tree-loop-im to get
the loop to interchanged.
-O2 -fno-tree-pre -fno-tree-loop-im -floop-interchange works while just -O2
-floop-interchange does n

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

perfect_nestify needs to be enhanced to handle this I guess. In fact we cannot
distribute these loops but need to undo what PRE/lim do.
