Java can run C/C++: https://github.com/oracle/graal/tree/master/sulong https://github.com/oracle/graal/tree/master/sulong What's your point?

  Ok. So you're positing that a giant heavy runtime, written in C++, via a library, can then run C++ code faster than...C++? Good luck.

    It actually really runs slower as is it first an interpreter, and the compiler is yet to be optimized to GCC levels; but is has a great compiler infrastructure that could eventually JIT to faster code (it being a runtime compilation, that has statistics, and Graal being capable of partial evaluation) I was merely pointing at a hole in your argument: the language of the compiler has absolutely no influence in the quality of it's output (again: the JVM compiles to assembly, not to C++). A compiler written in brainfuck could write code that is more performant than gcc does. The language does have an influence on compilation speed, though. But that matter in your argument?

    Actually that can indeed be possible — have a look at Futamura projections. Also, there are AOT compilers that can make use of profile information.
