Various other tests in this set have already run into this, and the solution has been to disable this loop distribution transformation, enabled at -O2, so that the vectorizer gets a chance to transform the loop and, in this testcase, fail to do so. for gcc/testsuite/ChangeLog * gcc.dg/vect/costmodel/ppc/costmodel-vect-31a.c: Disable ldist.
