--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #2) > Started with r12-3222-g89f33f44addbf9853bc3e6677db1fa941713cb6c > but got fixed with r12-3250-g67927342290c61d7e054430f1d7a7281f1f97fae > So I think we just want to add the testcase to the testsuite and close.
