[Joern RENNECKE]

Consideriing this code:

  if (onlyjump_p (i2)
      || (returnjump_p (i2) && !side_effects_p (PATTERN (i2))))
    {
      last2 = i2;
      /* Count everything except for unconditional jump as insn.  */
      if (!simplejump_p (i2) && !returnjump_p (i2) && last1)
        ninsns++;
      i2 = PREV_INSN (i2);
    }

you count unconditional jumps with a clobber, but you don't count
conditional returns (, or even an instruction that solves a travelling
salesman problem and returns if it finds a solution within a given cost 
bound).
