Low level are local optimizations, which basically will be the
same if you use the same backend (like LLVM). It would just
measure the

That is a good idea, if you want to measure compiler

Hopefully, as I understand GCC uses a highlevel IR, but if
performance is equal that is a pretty

Depends what you mean by "processes" :-)
In this comparison it is actually interesting, because D has
its own bignum implementation in the standard library.
There you go!

Thanks, I did not know this. :)
I would not consider it cheating. Using builtins in C is not
portable C11 either. It also shows off how D does versions.
