	2004-10-16  Jan Hubicka  <jh@suse.cz>

	* cgraph.c (decide_is_variable_needed): New function.
	(cgraph_varpool_finalize_decl): Use it.
	* cgraphunit.c (cgraph_optimize): Assemble_pending_decls when not doing
	unit-at-a-time.
	* final.c (output_addr_const): Do not call mark_referenced.
	* passes.c (rest_of_decl_compilation): ifdef out DECL_RTL_SET_P hack;
	always go via cgraph.

	* cgraph.c (cgraph_varpool_first_unanalyzed_node): New global voriable
	(cgraph_varpool_last_needed_node): New static variable.
	(enqueue_needed_varpool_node): Break out from ...; add items to the
	end of queue; update first pointers.
	(cgraph_varpool_mark_needed_node): ... here.
	(cgraph_varpool_finalize_decl): Use enqueue_needed_varpool_node.
	(cgraph_varpool_assemble_pending_decls): Move to cgraphunit.c
	* cgraph.h (cgraph_varpool_node): Add analyzed field.
	(cgraph_varpool_first_unanalyzed_node): Declare.
	* cgraphunit.c: Include output.h.
	(cgraph_varpool_analyze_pending_decls): New function.
	(cgraph_varpool_assemble_pending_decls): Move from cgraph.c; bail out
	for errors, analyze pending decls.
	(cgraph_finalize_compilation_unit): Only analyze decls.
	(cgraph_optimize): Assemble the decls after expanding.
