cgraph.h (cgraph_node): New method expand_all_artificial_thunks.
2014-12-05 Martin Jambor <mjambor@suse.cz>
* cgraph.h (cgraph_node): New method expand_all_artificial_thunks.
(cgraph_edge): New method redirect_callee_duplicating_thunks.
* cgraphclones.c (duplicate_thunk_for_node): Donot expand newly
created thunks.
(redirect_edge_duplicating_thunks): Turned into edge method
redirect_callee_duplicating_thunks.
(cgraph_node::expand_all_artificial_thunks): New method.
(create_clone): Call expand_all_artificial_thunks.
* ipa-cp.c (perhaps_add_new_callers): Call
redirect_callee_duplicating_thunks instead of redirect_callee.
Also call expand_all_artificial_thunks.
