--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- While the improved predicates make the first IN_RANGE tests unneeded, IMHO it should still verify what the second IN_RANGE tests did, i.e. that operands[2] is not 0 and at most 32 - third operand. I think the combiner just blindly tries to match and simplify, all the verification is performed through trying to recog the insn.
