* ipa-prop.h (enum ipa_lattice_type): Changed comments.
(struct ipa_param_descriptor): New fields types and
cannot_devirtualize.
(ipa_param_cannot_devirtualize_p): New function.
(ipa_param_types_vec_empty): Likewise.
(ipa_make_edge_direct_to_target): Declare.
* ipa-cp.c: Fixed first stage driver name in initial comment,
described devirtualization there too.
(ipcp_analyze_node): Call ipa_analyze_params_uses.
(ipcp_print_all_lattices): Print devirtualization info.
(ipa_set_param_cannot_devirtualize): New function.
(ipcp_initialize_node_lattices): Set cannot_devirtualize when setting
lattice to BOTTOM.
(ipcp_init_stage): Merged into...
(ipcp_generate_summary): ...its caller.
(ipcp_change_tops_to_bottom): Also process type lists.
(ipcp_add_param_type): New function.
(ipcp_copy_types): Likewise.
(ipcp_propagate_types): Likewise.
(ipcp_propagate_stage): Also propagate types.
(ipcp_need_redirect_p): Variable jump_func moved to its scope block.
Also return true if propagated types require it.
(ipcp_update_callgraph): Dump redirection info.
(ipcp_process_devirtualization_opportunities): New function.
(ipcp_const_param_count): Include known type information.
(ipcp_insert_stage): Call ipcp_process_devirtualization_opportunities
on new node. Fixed formatting.
* ipa-prop.c (make_edge_direct_to_target): Renamed to
ipa_make_edge_direct_to_target and changed all callers. Made
externally visible.
(ipa_node_duplication_hook): Duplicate types vector.
* cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Also try to
redirect outgoing calls for which we can't get a decl from the
statement. Check that we can get a decl from the call statement.
* ipa-inline.c (inline_indirect_intraprocedural_analysis): Call
ipa_analyze_params_uses only when ipa-cp is disabled.
* tree-inline.c (get_indirect_callee_fndecl): Removed.
(expand_call_inline): Do not call get_indirect_callee_fndecl.
* params.def (PARAM_DEVIRT_TYPE_LIST_SIZE): New parameter.
* Makefile.in (ipa-cp.o): Add gimple.h to dependencies.
* testsuite/g++.dg/ipa/devirt-1.C: New test.
* testsuite/g++.dg/ipa/devirt-2.C: Likewise.
* testsuite/g++.dg/ipa/devirt-3.C: Likewise.
* testsuite/g++.dg/ipa/devirt-4.C: Likewise.
* testsuite/g++.dg/ipa/devirt-5.C: Likewise.
* testsuite/gcc.dg/ipa/iinline-3.c: Likewise.
