Is it required by C++ standard to bypass "construction" in case of trivial constructor, or just implementation-dependent? In which cases is a construction bypassed? Thanks a lot!

Is it required by C++ standard to bypass "construction" in case of trivial constructor, or just implementation-dependent? In which cases is a construction bypassed? To answer the questions in reverse order. No construction occurs when the constructor is trivial. However, for a class to have a trivial constructor means more than it just has the compiler generated one. The class also needs to have no virtual functions, no virtual bases, and all of it's subobjects (bases and non-static members) must also have trivial constructors.
