I'm wondering if the code in tree-ssa-structalias.c can be invoked in a whole program mode? There are some comments in there about it not playing well with WHOPR and WPA (not that I intend to use that way.) Ironically, in the literature on points-to analysis this algorithm was only originally intended to be run on whole programs.
By the way, how are the users of the points-to sets actually supposed to access and use them? Thanks, Gary
