Subject: [PR 79108] Put ipa_node_params to GC memory

2017-01-23  Martin Jambor  <mjambor@suse.cz>

	PR ipa/79108
	* ipa-prop.h (ipa_param_descriptor): Anotate with with GTY(()).
	(ipa_node_params): Annotate with GTY((for_user)).  Make descriptors
	field a pointer to garbage collected vector, mark lattices and
	ipcp_orig_node with GTY((skip)).
	(ipa_get_param_count): Adjust to descriptors being a pointer.
	(ipa_get_param): Likewise.
	(ipa_get_type): Likewise.
	(ipa_get_param_move_cost): Likewise.
	(ipa_set_param_used): Likewise.
	(ipa_get_controlled_uses): Likewise.
	(ipa_set_controlled_uses): Likewise.
	(ipa_is_param_used): Likewise.
	(ipa_node_params_t): Move into garbage collector.  New methods insert
	and remove.
	(ipa_node_params_sum): Annotate wth GTY(()).
	(ipa_check_create_node_params): Adjust to ipa_node_params_sum being
	garbage collected.
	(ipa_load_from_parm_agg): Adjust declaration.
	* ipa-icf.c (param_used_p): Adjust to descriptors being a pointer.
	* ipa-profile.c (ipa_profile): Likewise.
	* ipa-prop.c (ipa_get_param_decl_index_1): Likewise.
	(ipa_populate_param_decls): Make descriptors parameter garbage
	collected.
	(ipa_dump_param): Adjust to descriptors being a pointer.
	(ipa_alloc_node_params): Likewise.
	(ipa_initialize_node_params): Likewise.
	(load_from_param_1): Make descriptors parameter garbage collected.
	(load_from_unmodified_param): Likewise.
	(load_from_param): Likewise.
	(ipa_load_from_parm_agg): Likewise.
	(ipa_node_params::~ipa_node_params): Removed.
	(ipa_free_all_node_params): Remove call to delete operator.
	(ipa_node_params_t::insert): New.
	(ipa_node_params_t::remove): Likewise.
	(ipa_node_params_t::duplicate): Adjust to descriptors being a pointer,
	copy known_csts and known_contexts vectors.
	(ipa_read_node_info): Adjust to descriptors being a pointer.
	(ipcp_modif_dom_walker): Make m_descriptors field garbage
	collected.
	(ipcp_transform_function): Make descriptors variable garbage
	collected.

testsuite/
	* gfortran.dg/lto/pr79108_0.f90: New test.
