Rust having one of the most sophisticated optimising compiler backends? And a whole suite of language design choices that enable fast, correct code?


A JIT gives you the ability to target the current CPU better.


The parent comment is clearly talking about language design rather than the backend.

I say this because I often see Rust people say isn't a great that rust can do xyz and then I look into it and it's actually just basic dataflow analysis that any compiler does or just LLVM being clever.
