--- Comment #11 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- (In reply to Richard Biener from comment #10) > Is there any case where the frontend would make 'data' point into the > middle of the array and iteration over the array would end up accessing > elements on "both sides"? Can somebody write a short testcase where that > would happen? I've tried, but I have been unable to find such a test case, and I do not think this can (or should) happen.
