      re PR rtl-optimization/17581 (Long long arithmetic fails inside a switch/case statement when compiled with -O2)


	PR rtl-optimization/17581
	* cselib.c (cselib_process_insn): The last instruction of a libcall
	block, with the REG_RETVAL note, should be considered in the libcall.
	* gcse.c (do_local_cprop): Allow constants to be propagated outside
	of libcall blocks.
	(adjust_libcall_notes): Use simplify_replace_rtx instead of
	replace_rtx to avoid creating invalid RTL in REG_RETVAL notes.

	* gcc.dg/pr17581-1.c: New test case.

      tree-ssa-dom.c (struct edge_info): New structure holding edge equivalences and edge redirection information.


	* tree-ssa-dom.c (struct edge_info): New structure holding
	edge equivalences and edge redirection information.
	(get_eq_expr_value, record_dominating_conditions): Kill.
	(propagate_to_outgoing_edges): Renamed from cprop_into_phis.
	Call record_edge_info.
	(allocate_edge_info, free_edge_info): New.
	(tree_ssa_dominator_optimize): Use propagate_to_outgoing_edges
	rather than cprop_into_phis.  Free all edge infos before threading
	jumps.
	(thread_across_edge): Allocate new edge info structures as needed
	and store the redirection target into the edge info structure
	instead of the edge's AUX field.
	(dom_opt_initialize_block): Mark unused argument with ATTRIBUTE_UNUSED.
	(record_equivalence_from_incoming_edge): Lose unnecessary argument.
	Revamp code which finds and records equivalences associated with
	edges to use saved data in the edge_info structure.
	(record_equivalencs_from_phis): Similarly.
	(dom_opt_finalize_block): Revamp code which finds and records
	equivalences associated with edges to use saved data in the
	edge_info structure.
	(build_and_record_new_cond): New function.
	(record_conditions): Use build_and_record_new_cond to record
	dominating conditions.
	(record_edge_info): New function.
	(record_range): Tighten test for conditions which create
	useful range records.
