(array_at_struct_end_p): New function. (idx_infer_loop_bounds): Use it. (estimate_numbers_of_iterations_loop): Export. * predict.c (predict_loops): Use estimated_loop_iterations_int. Do not use PRED_LOOP_EXIT on exits predicted by # of iterations. (tree_estimate_probability): Call record_loop_exits. * tree-data-ref.c (get_number_of_iters_for_loop): Replaced by ... (estimated_loop_iterations, estimated_loop_iterations_int, estimated_loop_iterations_tree): New functions. (analyze_siv_subscript_cst_affine, compute_overlap_steps_for_affine_1_2, analyze_subscript_affine_affine): Use estimated_loop_iterations_int. (analyze_miv_subscript): Use estimated_loop_iterations_tree. * predict.def (PRED_LOOP_ITERATIONS): Update comment. (PRED_LOOP_ITERATIONS_GUESSED): New. * cfgloop.c (record_loop_exits): Do nothing if there are no loops. * cfgloop.h (estimate_numbers_of_iterations_loop, estimated_loop_iterations_int): Declare. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@122316 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cfgloop.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'gcc/cfgloop.c') diff --git a/gcc/cfgloop.c b/gcc/cfgloop.c index 62ee79c6cd1..12ce92cdd9e 100644 --- a/gcc/cfgloop.c +++ b/gcc/cfgloop.c @@ -1038,6 +1038,9 @@ record_loop_exits (void) edge_iterator ei; edge e; + if (!current_loops) + return; + if (current_loops->state & LOOPS_HAVE_RECORDED_EXITS) return; current_loops->state |= LOOPS_HAVE_RECORDED_EXITS; -- cgit v1.2.1
