But that's conditional on the "default" kind of vectorization. In this PR it's shown the emulated vector path needs it and I think the masked operation case will, too (though we might eventually never mask an integral MINUS_EXPR). So the following makes that handling unconditional. PR tree-optimization/109735 * tree-vect-stmts.cc (vectorizable_operation): Perform conversion for POINTER_DIFF_EXPR unconditionally.
