--- Comment #6 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- (In reply to Thomas Koenig from comment #5) > Fixing the dependency for identical=true is a Good Thing(TM), but > will not be enough to fix the test case: Hm, another thought. For this special case (calling the matmul library function) we could be passing a non-contiguous lhs to the library, leading to far less efficient code. So, the choice of what to fix exactly is probably a bit more complicated.
