 With C++ this fits. Most abstractions don't have an additional overhead
over a manual implementation.

Again, you are wrong to generalize.  It depends on the situation, the abstraction in question, and the code.

 

As I said, you have no idea what you are talking about in the context of low-level programming.

 I told you why it isn't practicable to suppress exceptions in C++
since the runtime uses a lot of exceptions.

And you were completely wrong when you said that.  Perhaps in /your/ field of programming you are correct - but you are ignoring the rest of the world.

 

Again, you demonstrate your total ignorance of the topic.

 Most of the time a nanosecond more doesn't count, especiailly because
usually you do more complex things in a virtual function.

Often that is correct.  Often it is /not/ correct.  The only thing we can all be sure of is that your laughable attempt at a benchmark here bears no relation to the real world - especially not the real world of small-systems programming.

 

The vast majority of processors produced and sold do not have any kind of branch prediction.

 Not today.

For every one of your favourite big x86 chips sold, there will be a hundred small microcontrollers - none of which has branch prediction.
