--- Comment #8 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Richard Biener from comment #7) > Without bisection it's hard to identify what fix to backport. Note the > original issue doesn't reproduce for me with a cross to > x86_64-apple-darwin15.6.0 from > x86_64-linux either (from the tip of the gcc 7 branch). Besides backporting something to the gcc 7 branch, there's also the matter of adding the testcase to the testsuite on 8/trunk, to ensure it doesn't regress in the future, and the adding the testcase part doesn't require bisection like backporting would.
