[Bug tree-optimization/33826] [4.1/4.2/4.3 Regression] GCC generates wrong code for infinitely recursive functions



------- Comment #2 from steven at gcc dot gnu dot org  2007-11-05 21:38 -------
It seems to me that a recursive function can never be safely treated as
const/pure. In fact, any function in an SCC in the call graph could result in
an endless loop and is therefore not const/pure. I'm assuming here that hanging
in an infinite loop is a "side-effect", and I understand this is a debatable
assumption.
