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.
