Browse Source 
2009-03-30  Vladimir Makarov  <vmakarov@redhat.com>

	* reload.c (push_reload, find_dummy_reload): Use df_get_live_out
	instead of DF_LR_OUT.

	* ira-lives.c (process_bb_node_lives): Ditto.

	* ira-color.c (ira_loop_edge_freq): Use df_get_live_{out,in}
	instead of DF_LR_{OUT,IN}.

	* ira-emit.c (generate_edge_moves, add_ranges_and_copies): Ditto.

	* ira-build.c (create_bb_allocnos, create_loop_allocnos): Ditto.
