loop.texi: Document number_of_latch_executions and number_of_cond_exit_executions.
* doc/loop.texi: Document number_of_latch_executions and
number_of_cond_exit_executions.
* tree-scalar-evolution.c (compute_overall_effect_of_inner_loop,
chrec_is_positive, number_of_iterations_for_all_loops,
scev_const_prop): Use number_of_latch_executions.
(set_nb_iterations_in_loop): Do not increase the value of the
number of iterations.
(number_of_iterations_in_loop): Renamed to ...
(number_of_latch_executions): ... this.
(number_of_exit_cond_executions): New function.
* tree-scalar-evolution.h (number_of_iterations_in_loop): Declaration
removed.
(number_of_latch_executions, number_of_exit_cond_executions): Declare.
* tree-ssa-loop-ivcanon.c (canonicalize_loop_induction_variables): Use
number_of_latch_executions.
* tree-data-ref.c (get_number_of_iters_for_loop): Use
number_of_exit_cond_executions.
* tree-vect-analyze.c (vect_get_loop_niters): Ditto.
