onsideriing 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).
