If you are looking to work with computers, you can always try applying as a cashier at your local fast food joint.

They did not specify that they need extremely dumb freelance C++
developers (such are indeed rare) so perhaps they found some during
2 years.

The process is instantiated, hard coded text sections are simply part of that,
they are not instantiated in their own right. That happens to runtime created
objects. Otherwise you might as well say a class is instantiated just by dint
of it existing in the code even before an object has been created from it.
 
Here's an idea - how about you stick to giving vocabulary lessons in Finnish
or Estonian or whatever your native language is, and leave native English
speakers like me to define what the words in our language mean.

"Existing in the code"? You mean the source code?
 
I am precisely making the distinction between compile-time constructs
and runtime constructs. Source code, such as class declarations, are
compile-time constructs. The class declaration itself doesn't exist
at runtime. The data inside of the class may be instantiated as a
data structure.
 
Which one of these are, in your opinion, instantiations of a given
class, and which ones aren't?
 
static const MyClass obj1;
static MyClass obj2;
 
void foo()
{
static MyClass obj3;
MyClass obj4;
MyClass* obj5 = new MyClass;
}

Here's a better idea: Why don't you go and fuck yourself?

Deliberate failure to comprehend the question noted. Language where
rubbish can't be expressed has not been invented yet. So, boltar, you
are offal regardless of what language you can or can not speak.

fwiw, there is a way to get rid of the acquire barrier in the
stack::flush function. The only difference is that some relaxed barriers
would become consume. This is fine on most arch's because they are
no-ops wrt memory barriers, except dec alpha.
