@aandvalenzuela, @cmsbuild, @iarspider, @smuzaffar can you please review it and eventually sign? Thanks.
@antoniovilela, @mandrenguyen, @rappoccio, @sextonkennedy you are the release manager for this.

cms-bot internal usage

please test

test parameters:

• full_cmssw = true

please test

@gartung , any specific reason to add this? have you done any performance studies? If I understand correctly -fno-omit-frame-pointer is good for debugging applications

I agree that it may be a useful addition for debugging and profiling, but I would like to check the impact on the HLT performance before merging this.

This is meant to improve profiling.

I have not done any performance studies.

Can you suggest a workflow to test the HLT timing?

Can you suggest a workflow to test the HLT timing?

Unfortunately no, nothing out of the box :-/

OK

please test

please test with #9568

@gartung without #9568 test will fail again

Thanks

Closing for now as this did not improve the attribution of orphaned call stacks in gprofng or perf. Perf implements lbr stack stitching which still produces orphaned stacks. Vtune uses the vendor knowledge that TBB keeps track of the pointer to the spawned process that executes the code.
