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.
