--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
ICEs since r13-1754-g7a158a5776f5ca95a318 when the check has been added.
Anyway, looking just at dumps, reassoc1 does this since
r5-4662-gd5e254e19c59fcc49265dda
That commit looks unrelated, but it actually changes quite a lot the generated
IL for some reason already starting with ssa dump.
