Well, C++ has the likely/unlikely attribute to somewhat prefer a branch over the other in the eye of the branch predictor, and C++, Rust and some other low-level languages do have native SIMD support (note: C doesn’t have an official one, just compiler-specific ones. So in this vein it is actually higher level than Rust or C++).

Depend what you mean by official. There are likely more compilers implementing GCC vector extensions than there are rust compilers.
