help with -finstrument-functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am trying to profile the program with gcc. I am inserting the data into
an array which is later used to generate a file.

I am having a problem using template class (std::atomic<int>). Program is
multithreaded. So, I need to use atomics.
Right now, the __cyg_profile_func_enter is called for
std::__atomic_base<int>::operator++ as well.

I even tried setting the compile parameters to ignore it with:
-finstrument-functions
"-finstrument-functions-exclude-function-list=std::__atomic_base<int>::operator++>"

But I am unable to make the compiler ignore the function.
Is there a way for the compiler to make ignore a predefined function?

Any pointers about using the __cyg_profile_func_* functionality will be
helpful.

Thanks,
- Akshit
