| 54 | data was gathered for only the current function (the top of the stack)\r | |
| 55 | or for all functions on the stack. This corresponds to whether the\r | |

| 78 | A line for each (split) function with counts. Each line contains an\r | |
| 79 | integer count of the number of ticks while the function was current.\r | |
| 80 | In addition, if stack data was gathered (<span class="monospaced">-profile-stack true</span>), then\r | |
