--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Do we warn in this case (something like condition is always false)?
clang has -Wtautological-compare warning that warns say for
int b;
if (b != b)
but doesn't already for
int a[10], i;
if (a[i] != a[i]).
gcc has -Wtype-limits, which partially overlaps the -Wtautological-compare, so
if we introduce it, we should probably just add there the cases not already
covered by -Wtype-limits.
