Use func_checker::hash_operand for hashing of GIMPLE operands.
2019-11-14 Martin Liska <mliska@suse.cz>
* ipa-icf-gimple.h (func_checker::func_checker): Add
default constructor.
* ipa-icf.c (sem_function::init): Make operand_equal_p
and hash_operand public.
(sem_item::add_expr): Remove.
(sem_item::add_type): Remove.
(sem_function::hash_stmt): Use m_checker for hashing
of GIMPLE statements.
(sem_function::parse): Init with checker.
(sem_variable::parse): Pass NULL as checker.
(sem_item_optimizer::parse_funcs_and_vars):
Pass checker to ::parse function.
(sem_item_optimizer::parse_nonsingleton_classes): Likewise.
(sem_variable::parse): New function.
(sem_variable::get_hash): Only return computed hash value.
(sem_variable::init): Initialize hash of a variable.
* ipa-icf.h: Remove add_expr, add_type and add func_checker
to couple of functions as a new argument.
