--- Comment #2 from Tom Tromey <tromey at gcc dot gnu.org> ---
Suppose 'x' is of bitwise type.
Is "x == x" an allowable operation?
On the one hand, it isn't obvious whether "==" is "strictly bitwise".
On the other hand, this seems well-defined, at least in
cases where no promotion is needed.
This applies to "!=" as well.
