Ezgi Çiçek b64ed0bbf2 [impurity] Consider functions with empty pulse summary as impure Summary: As exemplified by added tests, pulse computes an empty summary (with 0 disjuncts) whenever it discovers a contradiction which might be caused by: - discovering aliasing in memory - widening limited number of times in loops and concluding that loop exit conditions are never taken However, AFAIU, it is not possible to have a function with 0 disjunct apart from such anomalities. Even a function which does nothing like `void foo(){}` has 1 disjuncts: ``` Pulse: 1 pre/post(s) #0: PRE: { roots={ }; mem ={ }; attrs={ };} POST: { roots={ }; mem ={ }; attrs={ };} SKIPPED_CALLS: { } ``` The aim of this diff is to consider functions with 0 disjuncts as impure because most often such cases are impure, rather than actually pure.
