IPA ICF: rewrite references into a hash_map.
2019-06-04 Martin Liska <mliska@suse.cz>
* ipa-icf.h (struct sem_usage_pair_hash): New.
(sem_usage_pair_hash::hash): Likewise.
(sem_usage_pair_hash::equal): Likewise.
(struct sem_usage_hash): Likewise.
* ipa-icf.c (sem_item::sem_item): Initialize
referenced_by_count.
(sem_item::add_reference): Register a reference
in ref_map and not in target->usages.
(sem_item::setup): Remove initialization of
dead vectors.
(sem_item::~sem_item): Remove usage of dead vectors.
(sem_item::dump): Remove dump of references.
(sem_item_optimizer::sem_item_optimizer): Initialize
m_references.
(sem_item_optimizer::read_section): Remove useless
dump.
(sem_item_optimizer::parse_funcs_and_vars): Likewise here.
(sem_item_optimizer::build_graph): Pass m_references
to ::add_reference.
(sem_item_optimizer::verify_classes): Remove usage of dead
vectors.
(sem_item_optimizer::traverse_congruence_split): Return true
when a class is split.
(sem_item_optimizer::do_congruence_step_for_index): Use
hash_map for look up of (sem_item *, index). That brings
significant speed up.
(sem_item_optimizer::do_congruence_step): Return true
when a split is done.
(congruence_class::is_class_used): Use referenced_by_count.
