The more advanced toolchains are doing similar things.
They instrument themselves, determine what the code+data
is *actually* doing at runtime, and optimise the **** out
of that.

That's as opposed to what the compiler can guess they
are doing and where a compiler has to make pessimising
assumptions.

And such techniques also work with C. For 18 year old
(gulp) results, google for "hplb dynamo".

And don't forget that some related techniques are implemented
in processor's hardware microarchitecture.

You are correct in presuming that you can't do an
optimal job at compile time, since the information
isn't there - and can't be there.

The bonus of avoiding getting toolchains to make
premature optimisations, is that the same runtime
optimisation techniques also work with different
processors.

There are disadvantages, of course. TANSTAFFL.
