        * tree-vect-transform.c (vect_estimate_min_profitable_iters): Multiply
        cost of inner-loop stmts (in outer-loop vectorization) by estimated
        inner-loop bound.
        (vect_model_reduction_cost): Don't add reduction epilogue cost in case
        this is an inner-loop reduction in outer-loop vectorization.
        (vect_model_load_cost): Add dr_explicit_realign case. Replace
        dr_unaligned_software_pipeline case with
        dr_explicit_realign_optimized case.

2007-06-17  Dorit Nuzman  <dorit@il.ibm.com>

        * tree-vectorizer.c (new_loop_vec_info): Initialize
        LOOP_VINFO_COST_MODEL_MIN_ITERS.
        * tree-vectorizer.h (_loop_vec_info): Added new filed
        min_profitable_iters.
        (LOOP_VINFO_COST_MODEL_MIN_ITERS): New access macro ti above new field.
        (TARG_SCALAR_TO_VEC_COST): Define cost of scalar to vector operation.
        * tree-vect-analyze.c (vect_analyze_operations): Set
        LOOP_VINFO_COST_MODEL_MIN_ITERS.
        * tree-vect-transform.c (vect_estimate_min_profitable_iters): Use
        VEC_length to determine if there are any LOOP_VINFO_MAY_MISALIGN_STMTS.
        Fix calculation of peel_iters_prologue. Move consideration of epilogue
        and prologue cost to after they are computed.
        (vect_model_induction_cost): Use TARG_SCALAR_TO_VEC_COST instead of
        TARG_VEC_STMT_COST.
        (vect_model_simple_cost): Takes additional argument dt. Consider cost
        of creating vectors from scalars according to dt.
        (vect_model_store_cost): Likewise.
        (vectorizable_call): Use dt array instead of scalar dt. Call
        vect_model_simple_cost with additional argument dt.
        (vectorizable_assignment): Likewise.
        (vectorizable_operation): Likewise.
        (vectorizable_type_demotion): Likewise.
        (vectorizable_type_promotion): Likewise.
        (vectorizable_store): Use dt array instead of scalar dt. Call
        vect_model_store_cost with additional argument dt.
        (vect_do_peeling_for_loop_bound): Don't call
        vect_estimate_min_profitable_iters. Instead, lookup
        LOOP_VINFO_COST_MODEL_MIN_ITERS. Don't always print
        "may not be profitable".
