unroll.c (loop_iteration_var, [...]): No longer static.
* unroll.c (loop_iteration_var, loop_initial_value, loop_increment loop_final_value, loop_comparison_code): No longer static. (unroll_loop): Delete loop_start_value update. * loop.h (loop_iteration_var, loop_initial_value, loop_increment, loop_final_value, loop_comparison_code): Extern. (loop_start_value): Delete extern. * loop.c (loop_can_insert_bct, loop_increment, loop_start_value, loop_comparison_value, loop_comparison_code): Delete. (loop_optimize): Remove initialization for deleted variables. (strength_reduce): Delete analyze_loop_iterations call. Only call insert_bct if flag_branch_count_on_reg set. (analyze_loop_iterations): Delete. (insert_bct): Remove iteration count calculation. Move checks for viable BCT optimization to here. Obtain iteration count from loop_iterations and correct for unrolling. Check for enough iteration to be beneficial. Comment out runtime iteration count case. (insert_bct): Print iteration count in dump file. Remove loop_var_mode and use word_mode directly. * rs6000.h (processor_type): Add PROCESSOR_PPC604e. * rs6000.c (rs6000_override_options): Use it. (optimization_options): Enable use of flag_branch_on_count_reg. * rs6000.md (define_function_unit): Describe 604e. From-SVN: r22852
