| perf supports a simple JIT interface to resolve symbols for dynamic code generated | |
| by a JIT. | |
| The JIT has to write a /tmp/perf-%d.map (%d = pid of process) file | |
| This is a text file. | |
| Each line has the following format, fields separated with spaces: | |
| START SIZE symbolname | |
| START and SIZE are hex numbers without 0x. | |
| symbolname is the rest of the line, so it could contain special characters. | |
| The ownership of the file has to match the process. |
