What |Removed |Added
----------------------------------------------------------------------------
Status|NEW |RESOLVED
Known to work| |7.1.0
Resolution|--- |FIXED
Known to fail| |5.1.0, 6.1.0
Target Milestone|--- |7.0
--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed in GCC 7.
What was missing was not optimizing:
ppnode.1_5 = &_15->m_next;
if (&n == ppnode.1_5)
Even though n never escaped.
