re PR tree-optimization/42366 (ICE in ipa_write_node_info, at ipa-prop.c:2023) 

2010-01-04  Martin Jambor  <mjambor@suse.cz>

	PR tree-optimization/42366
	* ipa-cp.c (ipcp_init_stage): Always call ipa_compute_jump_functions on
	edges with variable number of parameters.
	* ipa-prop.c (ipa_write_node_info): Stream out uses_analysis_done
	flag instead of asserting it.
	(ipa_read_node_info): Read uses_analysis_done flag.
