--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Most likely introduced with r231152
operands[2] = gen_reg_rtx (SImode);
in the splitter is just wrong, unless the splitter is limited to
can_create_pseudo_p (), but as the bswap insn has # for this alternative, there
needs to be a way to handle it even after reload.
