	gcc            : ChangeLog final.c output.h predict.c toplev.c 
	gcc/doc        : tm.texi 

Log message:
	* final.c (compute_alignments): New function.
	(init_insn_lengths): Do not care label_align.
	(LABEL_ALIGN_AFTER_BARRIER): Default to 1.
	(LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Default to 0.
	(JUMP_ALIGN, JUMP_ALIGN_MAX_SKIP): New.
	(shorted_branches): Realloc label_align array; do
	not call init_insn_lengths; Do not care about loop alignments.
	* output.h (compute_alignments): Declare.
	* toplev.c (rest_of_compilation): Call compute_alignments.
	* tm.texi (JUMP_ALIGN, JUMP_ALIGN_MAX_SKIP): Document.
	
	* predict.c (block_info_def): Add npredecesors, remove nvisited;
	change visited to tovisit.
	(propagate_freq): Use faster traversing algorithm.
	(estimate_loops_at_level, estimate_bb_frequencies): Change visited
	to tovisit; reverse meaning.
	
	* predict.c (struct block_info_def): Remove nvisited.
	(propagate_freq): Use EDGE_DFS_BACK to detect irreducible regions.
	(estimate_bb_frequencies): Call mark_dfs_back_edges.
