Integrate that for IPA ICF.
2019-10-30 Martin Liska <[email protected]>
* ipa-icf-gimple.c (func_checker::hash_operand): New.
(func_checker::compare_cst_or_decl): Remove handling
of FIELD_DECL.
(func_checker::compare_operand): Transform to ...
(func_checker::operand_equal_p): ... this.
* ipa-icf-gimple.h (class func_checker): Add
operand_equal_p and hash_operand.
* ipa-icf.c (sem_function::equals_private): Fix
pushing and popping of cfun.
