In passing, I noticed we currently define wrapper overloads of coerce_template_parms that effectively default complain and require_all_args, but it seems cleaner to specify default arguments for the main overload instead. And I suppose we should also give c_innermost_t_p the same defaults. However, I'm not sure about defaulting complain to tf_none since it's contrary to how we default every other complain parameter to either tf_error or tf_warning_or_error (for sake of non-SFINAE callers), so this tf_none default seems surprising. And since just three callers (all in constraint.cc) use this complain=tf_none default, and just one caller (determine_specialization) passes complain=tf_warning_or_error, it seems best to just not default complain here. Bootstrapped and regtested on x86_64-pc-linux-gnu, does this look OK for trunk? gcc/cp/ChangeLog: * constraint.cc (resolve_function_concept_overload): Explicitly pass tf_none to coerce_template_parms.
