Subject: 	* tree-ssa-loop-niter.c (number_of_iterations_exit): New parameter
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cbe26b293dd751e67e598be62cf5df40e1268992;p=thirdparty%2Fgcc.git

	* tree-ssa-loop-niter.c (number_of_iterations_exit): New parameter
	EVERY_ITERATION with implicit value of true.
	(record_estimate): Check dominance relationship of the basic block
	we are estimating on instead of relying on UPPER to be false.
	(struct ilb_data): Drop RELIABLE.
	(idx_infer_loop_bounds): Update.
	(infer_loop_bounds_from_ref): Drop parameter RELIABLE.
	(infer_loop_bounds_from_array): Drop parameter RELIABLE.
	(infer_loop_bounds_from_undefined): Update comments and handling
	of RELIABLE.
	(estimate_numbers_of_iterations_loop): Record all bounds.
