@dberlin Thank you for your comments. I agree on you that it is not easy to invent a good heuristics around this knob, but still I find this useful for some cases that actually matters. Assuming that this doesn't make the implementation much complex, wouldn't it be better for compiler users to have more options?

I'm still collecting numbers. Will post it here once I have them all.
