URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=123416
Log:
        * tree-vectorizer.c (new_stmt_vec_info): When setting def_type for
        phis differentiate loop-header phis from other phis.
        (bb_in_loop_p): New function.
        (new_loop_vec_info): Inner-loop phis already have a stmt_vinfo, so just
        update their loop_vinfo.  Order of BB traversal now matters - call
        dfs_enumerate_from with bb_in_loop_p.
        (destroy_loop_vec_info): Takes additional argument to control whether
        stmt_vinfo of the loop stmts should be destroyed as well.
        (vect_is_simple_use): Check for multiple-types in inner-loop (currently
        not supported during outer-loop vectorization).
        (vect_is_simple_reduction): Allow the "non-reduction" use of a
        reduction stmt to be defines by a non loop-header phi.
        (vectorize_loops): Call destroy_loop_vec_info with additional argument.
        * tree-vectorizer.h (vect_relevant): Add enum values
        vect_used_in_outer_by_reduction and vect_used_in_outer.
        (is_loop_header_bb_p): New. Used to differentiate loop-header phis
        from other phis in the loop.
        (destroy_loop_vec_info): Add additional argument to declaration.
        * tree-vect-analyze.c (analyze_operations): Check for inner-loop
        loop-closed exit-phis during outer-loop vectorization that are live or
        not used in the outerloop, cause this requires special handling.
        (vect_enhance_data_refs_alignment): Don't consider versioning for
        nested-loops.
        (vect_analyze_data_refs): Check that there are no datarefs in the
        inner-loop.
        (vect_mark_stmts_to_be_vectorized): Also consider vect_used_in_outer
        and vect_used_in_outer_by_reduction cases.
        (process_use): Also consider the case of outer-loop stmt defining an
        inner-loop stmt.
        (vect_analyze_loop_1): New function.
        (vect_analyze_loop_form): Extend, to allow a restricted form of nested
        loops.  Call vect_analyze_loop_1.
        (vect_analyze_loop): Skip (inner-)loops within outer-loops that have
        been vectorized.  Call destroy_loop_vec_info with additional argument.
        * tree-vect-patterns.c (vect_recog_dot_prod_pattern): Add check for
        GIMPLE_MODIFY_STMT (in case we encounter a phi in the loop).
        * tree-vect-transform.c (vect_init_vector): Check which loop to work
        with, in case there's an inner-loop.
        (get_initial_def_for_inducion): Extend to handle outer-loop
        vectorization.
        (vect_get_vec_def_for_operand): Support phis in the case vect_loop_def.
        In the case vect_induction_def get the vector def from the induction
        phi node (instead of calling get_initial_def_for_inducion.
        (vect_finish_stmt_generation): Support the case that the new stmt is
        to be added after a label (rather than before some other stmt).
        (get_initial_def_for_reduction): Extend to handle outer-loop
        vectorization.
        (vect_create_epilog_for_reduction): Extend to handle outer-loop
        vectorization.
        (vectorizable_reduction): Check for multiple-types in inner-loop
        (currently not supported during outer-loop vectorization).
        (vect_transform_loop): Change assert to just skip this case.  Add a
        dump printout.
