ok, corrected.

  else if (mips_opts.mips16
	   && ! ip->use_extend
	   && *reloc_type != BFD_RELOC_MIPS16_JMP)
    {     
      if ((pinfo & INSN_UNCOND_BRANCH_DELAY) == 0)
	/* Make sure there is enough room to swap this instruction with
	   a following jump instruction.  */
	frag_grow (6);
      add_fixed_insn (ip);
