        PR tree-optimization/69168
        * tree-vect-loop.c (vect_analyze_loop_2): Reset both main and
        pattern stmt SLP type.
        * tree-vect-slp.c (vect_detect_hybrid_slp_stmts): Patterns may
        end up unused so cope with that case.

        * gcc.dg/torture/pr69168.c: New testcase.
