2011-09-23 Martin Jambor <mjambor@suse.cz>
* ipa-prop.h (jump_func_type): Updated comments.
(ipa_known_type_data): New type.
(ipa_jump_func): Use it to describe known type jump functions.
* ipa-prop.c (ipa_print_node_jump_functions_for_edge): Updated to
reflect the new known type jump function contents.
(compute_known_type_jump_func): Likewise.
(combine_known_type_and_ancestor_jfs): Likewise.
(try_make_edge_direct_virtual_call): Likewise.
(ipa_write_jump_function): Likewise.
(ipa_read_jump_function): Likewise.
* ipa-cp.c (ipa_value_from_known_type_jfunc): New function.
(ipa_value_from_jfunc): Use ipa_value_from_known_type_jfunc.
(propagate_accross_jump_function): Likewise.
