| 2 | by a JIT. |
| 3 | |
| 4 | The JIT has to write a /tmp/perf-%d.map (%d = pid of process) file |
| 5 | |
| 6 | This is a text file. |
| 7 | |
| 8 | Each line has the following format, fields separated with spaces: |
| 9 | |
| 10 | START SIZE symbolname |
| 11 | |
| 12 | START and SIZE are hex numbers without 0x. |
| 13 | symbolname is the rest of the line, so it could contain special characters. |
| 14 | |
| 15 | The ownership of the file has to match the process. |
