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). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23383
