--- Comment #24 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Martin Jambor from comment #23) > The testcase I posted to comment #19 fails also on the 4.9 branch so I > will test and commit the patch there too. > > Jakub, can I close the bug afterwards or do you want to backport the > gcc/tree-dfa.c (the patch in comment#11) to gcc 5 as well? If the bug is fixed in gcc 5 and/or 4.9 through your patch, the tree-dfa.c change is not needed there, let's keep tree-dfa.c as is there.
