O. Then I was indeed wrong and defaulted does not impact ABI at all.
At least that is one worry less for the abi checkers :)
As Siva mentioned, it does in fact impact the ABI. A class with a
non-trivial destructor is not a POD, and affects the calling
convention, so the debugger needs to know the difference.
Yes, but defaulted does not imply trivial (though the converse is true),
so knowing whether a declaration is defaulted is neither necessary nor
sufficient to determine the parameter passing ABI. It would be good to
represent trivial_fn_p in the DWARF.
