[Bug tree-optimization/28364] poor optimization choices when iterating over a std::string (probably not c++-specific)



------- Comment #22 from rguenth at gcc dot gnu dot org  2006-07-13 08:28 -------
For practical purposes (determining the loop runs at least once) it needs to
duplicate the exit condition.  Which happens to be difficult here, as there are
multiple loop exits.
