--- Comment #9 from Segher Boessenkool <segher at gcc dot gnu.org> --- Another way is to not do a splitter at all, just have a separate define_insn for the case where the selection operand is a constant number, since the canonical representation then is different! (An IOR of two ANDs, no NOT in sight).
