Hi all,
 
I'm interested in developping a tool based on oprofile witch aim to show profiling results with callgraph support (like opreport tool). So I read the source code of opreport and tried to understand how callers and callees of each symbol are determined, but I did not success :(
I know that parsing XML output is much easier than parsing the sample files but I'm obliged to.
Please, I need some help from this mailing-list, no document is available to exlpain all that (except the source code !!).
Many thanks
