--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> --- Created attachment 34935 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34935&action=edit Suggested patch Following patch skips all alias variables. This condition was part of my initial version of patch: https://gcc.gnu.org/ml/gcc-patches/2015-02/msg01753.html I hope, as Honza rework the patch, this condition should be placed there.
