        * tree-vectorizer.h (vect_mark_stmts_to_be_vectorized,
        vect_analyze_data_refs): Add bool * arguments.
        * tree-vect-data-refs.c (vect_analyze_data_refs): Add fatal argument,
        if failure is due to scatter/gather, set *fatal to false if non-NULL.
        * tree-vect-stmts.c (vect_mark_stmts_to_be_vectorized): Likewise.
        * tree-vect-loop.c (vect_analyze_loop_2): Adjust
        vect_mark_stmts_to_be_vectorized and vect_analyze_data_refs callers.
        * tree-vect-slp.c (vect_slp_analyze_bb_1): Adjust
        vect_analyze_data_refs caller.

        * gcc.target/i386/pr91033.c: New test.
