--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Yes with -fnon-call-exceptions and -fsignaling-nans conditionals can (and
might) throw an exception.  Maybe a sorry early during option processing should
happen and turn off hardening of condtionals.

    [PR103024,PR103530] support throwing compares and non-boolean types

    This patch adjusts the harden-compares pass to cope with compares that
    end basic blocks, and to accept non-boolean integral types whose
    conversion to boolean may have been discarded.
