In a c++ file inside a loop I have the following snippet:

If I activate the line with "if (f) break;" then the performance
very much degrades.

Which g++ optimization parameter should I disable (or enable) to keep the
performance?

That depends on how f() is defined.  We need to see a test that we
can reproduce.

It's a simple class member function returning bool:

inline bool func() const
{
//...
}
