	* ipa-prop.h (struct ipa_param_descriptor): Removed the modified flag.
	(struct ipa_node_params): Removed the modification_analysis_done flag.
	(ipa_is_param_modified): Removed.
	(ipa_analyze_node): Declare.
	(ipa_compute_jump_functions): Remove declaration.
	(ipa_count_arguments): Likewise.
	(ipa_detect_param_modifications): Likewise.
	(ipa_analyze_params_uses): Likewise.
	* ipa-prop.c (struct param_analysis_info): New type.
	(visit_store_addr_for_mod_analysis): Removed.
	(visit_load_for_mod_analysis): Renamed to visit_ref_for_mod_analysis,
	moved down in the file.
	(ipa_detect_param_modifications): Merged into ipa_analyze_params_uses.
	(ipa_count_arguments): Made static.
	(mark_modified): New function.
	(is_parm_modified_before_call): New function.
	(compute_pass_through_member_ptrs): New parameter parms_info, call
	is_parm_modified_before_call instead of ipa_is_param_modified.
	(ipa_compute_jump_functions_for_edge): New parameter parms_info, pass
	it to compute_pass_through_member_ptrs.
	(ipa_compute_jump_functions): New parameter parms_info, pass it to
	ipa_compute_jump_functions_for_edge.  Call ipa_initialize_node_params
	on the callee if it is analyzed.  Made static.
	(ipa_analyze_indirect_call_uses): New parameter parms_info, call
	is_parm_modified_before_call instead of ipa_is_param_modified.
	(ipa_analyze_call_uses): New parameter parms_info, pass it to
	ipa_analyze_indirect_call_uses.
	(ipa_analyze_stmt_uses): New parameter parms_info, pass it to
	ipa_analyze_call_uses.
	(ipa_analyze_params_uses): New parameter parms_info, pass it to
	ipa_analyze_stmt_uses.  Also perform the used analysis.  Made static.
	(ipa_analyze_node): New function.
	(ipa_print_node_params): Do not dump the modified flag.
	(ipa_write_node_info): Assert uses_analysis_done rather than streaming
	it.  Do not stream the modified parameter flag.
	(ipa_read_node_info): Set uses_analysis_done to 1 instead of streaming
	it.  Do not stream the modified parameter flag.
	* ipa-cp.c (ipcp_analyze_node): Removed.
	(ipcp_init_stage): Iterate only once over the nodes, analyze each one
	with only a call to ipa_analyze_node.
	* ipa-inline.c (inline_indirect_intraprocedural_analysis): Analyze the
	node with only a call to ipa_analyze_node.

	* testsuite/g++.dg/ipa/iinline-3.C: New test.
	* testsuite/gcc.dg/ipa/modif-1.c: Removed.
