basic-block.h (BB_FLAGS_TO_PRESERVE): New define.

gcc/
	* basic-block.h (BB_FLAGS_TO_PRESERVE): New define.
	(brief_dump_cfg): Update prototype to take flags argument.
	(check_bb_profile): Remove prototype.
	* tracer.c (tracer): Update brief_dump_cfg calls.
	* cfghooks.c (dump_bb): Do not pass TDF_COMMENT to dump_bb_info.
	Call dump_bb_info before and after the cfghook dump_bb.  Terminate
	the dump with a newline.
	(dump_flow_info): Do not call check_bb_profile.
	* cfg.c (clear_bb_flags): Update using BB_FLAGS_TO_PRESERVE.
	(check_bb_profile): Make static.  Take indent and flags arguments.
	(dump_bb_info): Always dump loop depth.  With TDF_DETAILS, call
	check_bb_profile.  Print one edge per line.
	(brief_dump_cfg): Take a flags argument, and filter out
	TDF_COMMENT and TDF_DETAILS.
	* pretty-print.c (pp_base_newline): Set pp_needs_newline to false.
	* gimple-pretty-print.c (dump_gimple_bb_header): Do not use dump_bb_info
	here, it is already called from dump_bb.  Idem for check_bb_profile.
	(dump_gimple_bb_footer): Likewise.
	(gimple_dump_bb_buff): Call pp_flush after dump_gimple_stmt to
	avoid broken dumps for statement histograms.
	(gimple_dump_bb): Handle ENTRY_BLOCK and EXIT_BLOCK.  Do
	not call pp_flush here, the buffer should be empty.
	* sched-rgn.c (debug_region): Pass TDF_BLOCKS to dump_bb.
	* sched-vis.c (debug_bb_slim): Likewise.
	* tree-cfg.c (remove_bb): Pass dump_flags to dump_bb.
	(gimple_debug_bb): Pass TDF_BLOCKS to dump_bb.
	(gimple_dump_cfg): Do brief_dump_cfg with TDF_COMMENT.
	(dump_function_to_file): Do not call check_bb_profile on
	ENTRY_BLOCK and EXIT_BLOCK, check_bb_profile doesn't handle them.
	Use dump_bb instead of gimple_dump_bb.
	(print_loops_bb): Use dump_bb instead of gimple_dump_bb.
	* passes.c (execute_function_dump): Always call print_rtl_with_bb
	for RTL dumps.
	* cfgrtl.c (print_rtl_with_bb): Handle printing without an up-to-date
	CFG.  With TDF_BLOCKS and TDF_DETAILS, do DF dumps at the top and bottom
	of each basic block.

testsuite/
	* gcc.dg/tree-prof/update-loopch.c: Look for counts on the dumps of
	the basic block and check loop depth.
	* gcc.dg/tree-ssa/pr18133-1.c: Dump details, not blocks.  Update
	matching patterns and comments.
	* gcc.dg/tree-ssa/20031021-1.c: Fix check patterns.
	* gcc.dg/tree-ssa/vector-2.c: Likewise.
