Thank you very much for the advice. I will try __gcov_dump first.

Using AutoFDO is one way. For PGO, you may want to to try using
__gcov_dump interface to explicitly control the timing and order of
the profile dump --- i.e., invoke __gcov_dump in main process after
work processes exit and before the main process exits.

Hi,
I am trying PGO on Nginx, which has a main process and several worker processes.
I find that the collected profile data files only contain information
for the main process, which is probably a data race (the main process
exits immediately after worker processes exit).
How can I solve this prob
