"extremely eefficient native code". I don't argue that C++ has extremely efficient native code. But so has D. So the claim that C++ has an "enormous performance advantage" over D is specious.
We also need to keep in mind that for a small segment of C++ programmers it is important to be able to use CPU/SoC/hardware vendor backed compilers so that they can ship optimized code the day a new CPU is available. So there is a distinct advantage there for people who don't aim for consumer CPUs.
Most programmers don't care as much, since adoption of new CPUs is slow enough for GCC/Clang to catch up in time.
Anyway, as C++ is taking more and more of C's niche, this issue can be more an more "threatening". E.g. hardware vendors that now only ship C compilers might in the future only ship C++ compilers... I don't know exactly where this is going, but it is possible that C++ could become hard to displace for hardware oriented programming. Seems like more an more embedded programming is moving to C++ from C.
