Even if this puts LLVM at an unfair disadvantage, I think you will find that
LLVM will thrash MLton's current x86 backend anyway.
I did some benchmarking on HLVM and found that it was often several times
faster than OCaml when the GC is not the bottleneck:
And, of course, OCaml is fast as ML compilers go...
