I sent this solution to Vijayaraghavan Murali but actually, someone else in the list may someday be interested by it. Besides, I wanted to add that the Scope plug-in and the underlying Program Dependency Graph were instrumental in solving the ICPC industrial challenge, the write-up of which starts here: http://blog.frama-c.com/index.php?post/2011/06/06/Fixing-robots%2C-part-1 ______________ > The output from -pdg is almost exactly what I wanted, except since there is > no line number information printed, there is no way to find out which line > the [Elem]s correspond to.

This would solve all my problems. With the very little tested patch below, some nodes that can be annotated with a program point are. You may need a little work to adapt this to Carbon (it is a patch against the development version). The output is then displayed as: [pdg] RESULT for main: ? ? ?[Elem] 0 : InCtrl ? ? ?[Elem] 1 : VarDecl : vol ? ? ?[Elem] 2 (tests/misc/alias.i:40) : vol = (int volatile)0; ? ? ? ?-[-c-]-> 0 ? ? ? ?-[a--]-> 1 ? ? ?[Elem] 3 (tests/misc/alias.i:43) : A = 1; ? ? ? ?-[-c-]-> 0 ? ? ?[Elem] 4 (tests/misc/alias.i:44) : B = 2; ? ? ? ?-[-c-]-> 0 ? ? ?[Elem] 5 (tests/misc/alias.i:45) : Call18-InCtrl : f((char *)(& A),& B); ? ? ? ?-[-c-]-> 0 ? ? ?[Elem] 6 (tests/misc/alias.i:45) : Call18-In1 : f((char *)(& A),& B); ? ? ? ?-[-c-]-> 0 ? ? ? ?-[-c-]-> 5 Pascal --- src/pdg_types/pdgTypes.ml ?
