FYI, this is something I'm interested in for the JIT use case. My code has lots of essentially never executed slow paths and getting them pulled far away from the normal code is interesting. Note that my case may be different that others in that the blocks I'm interested in pulling away are stone cold/never executed. This gives a clear profitability heuristic which is one of the complex parts of doing this for the general case.
