It seems that in writing testcases for the operator<=> proposal I didn't include any tests for implicitly declared friend operator==, and consequently it didn't work. 2020-02-11 Jason Merrill <ja...@redhat.com> PR c++/93675 * class.c (add_implicitly_declared_members): Use do_friend. * method.c (implicitly_declare_fn): Fix friend handling. (decl_remember_implicit_trigger_p): New. (synthesize_method): Use it. * decl2.c (mark_used): Use it.
