--- Comment #9 from amker at gcc dot gnu.org --- (In reply to Markus Trippelsdorf from comment #8) > I think -fno-strict-overflow/-fwrapv should use the old behavior. > The kernel really needs a flag to control pointer wrapping. Well, GCC doesn't provide such a flag now. Before the change, it was -fno-strict-overflow/-fwrapv. And the support for wrapping pointer is far from complete, that's one point of the change.
