------- Comment #14 from rguenth at gcc dot gnu dot org 2008-06-04 17:03 ------- We do the exact opposite - type-based rules override points-to must-alias information (or really may-alias information). Also for the proposed scheme to work you need to guarantee that you always can compute correct points-to relations (I mean, if points-to information says pt_anything and if you then assume must-alias and thus a conflict then you simply disable TBAA completely).
