2012-06-05 Sandra Loosemore<san...@codesourcery.com>gcc/ * tree-ssa-loop-ivopts.c (comp_cost): Make complexity field signed. Update comments to indicate this is for addressing mode complexity. (new_cost): Make signedness of parameters match comp_cost fields. (compare_costs): Prefer higher complexity, not lower, per documentation of TARGET_ADDRESS_COST. (multiplier_allowed_in_address_p): Use (+ (* reg1 ratio) reg2) to probe for valid ratios, rather than just (* reg1 ratio). (get_address_cost): Rewrite to eliminate precomputation and caching. Use target's address cost for autoinc forms if possible. Only attempt sym_present -> var_present cost conversion if the sym_present form is not legitimate; amortize setup cost over loop iterations. Adjust complexity computation. (get_computation_cost_at): Adjust call to get_address_cost. Do not mess with complexity for non-address expressions. (determine_use_iv_cost_address): Initialize can_autoinc. (autoinc_possible_for_pair): Likewise.
