--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, OK.  With integer valued comparisons considered truth_valued_p
a ~ on them does not result in a truth_value_p.  That in the end means
that we'd need to sign-extend the result or restrict the pattern more.

I'm testing a patch.=
