--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Now verified, in the LTO case both wi::gt_p/wi::gtu_p and wi::lt_p/wi::ltu_p
are inlined and do:

       ja     0x1915edc <_ZNK14range_operator
so that looks like lh_range.val[0] !=3D 0 && lh_range.val[0] <=3D 3U, so I'=
m pretty
sure that is the STATIC_CONSTANT_P case.=
