This is with stock RedHat 6.1 (package glibc-2.1.2-11).
I have a multithreaded Linux application which I want to profile with
gprof. As near as I can tell, the call graph is correct but the
timing information is taken from the main thread only. I assume this
is primarily because the profiling timer signal is only being
delivered to the main thread.
Questions:
Is the call graph data actually correct? That is, are the routines
which gather that data thread-safe?
Are profiling timers per-thread? Is it possible for me to enable it
in the other threads? Would that even work?
Any suggestions would be appreciated. Thanks!
