--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Please show the (relevant part of) output of -fdump-rtl-combine-all ?  At least
those parts where it decided (ltu:SI (const_int 1) (const_int 0)) is valid (it
isn't) and where optimising that to (const_int 0) is valid (it isn't).
