I don't think there's much difference between C and C++ (and Rust, etc...) when it comes to this.

Idiomatic/natural rust tends to be a lot heavier on allocations and also physically moving objects around than the other two.

Can you elaborate on this? Slightly concerned because I'm have written (and planning to write more) Rust HPC code

		Maybe not what they meant, but Rust sometimes makes it tempting to just copy things rather than fighting the borrow checker. Whereas in C++ you're free to just pass pointers around and not worry about it until / unless your code crashes or gets exploited. Speaking authoritatively from my position as an incompetent C++ / Rust dev.

There is unless using a llvm compiler that does naive things with code motion.

Rust is typically slowest (often negligible <3%), C++ has better CUDA support, and C can be heavily optimized with inline assembly (very unforgiving to juniors.)

Also, heavily associated with coding style =3
