If the branch is 100% predicted then the "predicted" is hidden.
Similarly, if there is no branch tsx abort, the "abort" is hidden.
There is only cycles shown (cycle is supported on skylake platform,
older platform would be 0).

If no iterations, the "iterations" is hidden.

For example:

|--29.93%--main div.c:39 (predicted:50.6%, cycles:1, iterations:18)
|          main div.c:44 (predicted:50.6%, cycles:1)
|          |
|           --22.69%--main div.c:42 (cycles:2, iterations:17)
|                     compute_flag div.c:28 (cycles:2)
|                     |
|                      --10.52%--compute_flag div.c:27 (cycles:1)
|                                rand rand.c:28 (cycles:1)
|                                rand rand.c:28 (cycles:1)
|                                __random random.c:298 (cycles:1)
|                                __random random.c:297 (cycles:1)
|                                __random random.c:295 (cycles:1)
|                                __random random.c:295 (cycles:1)
|                                __random random.c:295 (cycles:1)
|                                __random random.c:295 (cycles:6)
