> You get different machine code using different compilers on identical pieces of source code. Ah, right - well I'm certainly not denying that. (I'm familiar with the topic, to be clear: I've written compilers. I just wasn't clear what exactly you were saying.) > It’s specifically in reference to rust use of LLVM not being sufficient to guarantee equivalence. Formally, no.
