A call through a function pointer doesn't necessarily cause a pipeline clear, but it may, depending on the scenario. The key is whether the CPU can effectively predict the destination of the branch ahead of time. The way that modern "big" out-of-order cores handle indirect calls1 is roughly as follows:
