--- Comment #9 from Kazumoto Kojima <kkojima at gcc dot gnu.org> 2011-11-28 23:29:57 UTC --- (In reply to comment #8) > Specifying -fno-tree-forwprop doesn't seem to have any effect on these cases. For that function, -fdump-tree-all shows that the tree loop ivopts optimization does it. Try -fno-tree-forwprop -fno-ivopts.
