	gcc            : ChangeLog.lno cfgrtl.c loop-iv.c opts.c 
	                 tree-cfg.c tree-ssa-loop-ivopts.c 

Log message:
	* cfgrtl.c (purge_dead_edges): Clean the EDGE_ABNORMAL_CALL flags.
	* loop-iv.c (iv_number_of_iterations): Handle the case when we prove
	that the loop does not roll.
	* opts.c (decode_options): Enable -floop-optimize2 and
	-ftree-loop-optimize by default.
	* tree-cfg.c (factored_computed_goto_label,
	factored_computed_goto): Removed.
	(factor_computed_gotos): Do not record them.
	(disband_implicit_edges): Do not unfactor computed jumps.
	* tree-ssa-loop-ivopts.c (force_gimple_operand): Give correct types
	to temporary variables.
	(idx_force_simple, create_iv, rewrite_use_nonlinear_expr,
	rewrite_use_address, rewrite_use_compare, rewrite_use_outer):
	Changed due to force_gimple_operand change.
	(find_bivs): Handle ill-typed assignments correctly.
